遮阳网是什么，有什么作用？
The role of shading nets
遮阳网可以避免植物受到强光暴晒、暴雨冲击、高温危害，还能阻碍病虫害的传播，比如阻止虫害迁移。
遮阳网主要在夏天使用，特别是在南方地区的使用范围较广。北方夏季通常覆盖白色薄膜，南方夏季通常覆盖黑色遮阳网。
除上述作用以外，遮阳网还具有一定的保温保湿能力。
遮阳网较多的只有黑色和灰色两种，两者之间稍微有些区别：黑色遮光率高，降温效果好，但是对光合作用影响较大，比较适合在叶菜类蔬菜上使用，如果在一些喜光类的蔬菜上使用应减少覆盖时间。银灰色遮阳网虽然降温效果不如黑色的，但对蔬菜的光合作用影响较小，可在茄果类等喜光蔬菜上使用。
一、遮阳网的作用
1、遮阳网主要应用在夏季，尤其是南方推广面积大。有人形容说：北方冬季是一片白（薄膜覆盖），南方夏季是一片黑（覆盖遮阳网）。
2、夏季在南方利用遮阳网栽培蔬菜已成为防灾保护的一项主要推广的技术措施。北方应用还只限于夏季蔬菜育苗。
3、夏季（6-8月）覆盖遮阳网主要作用是防烈日的照射、防暴雨的冲击、高温的危害、病虫害的传播，尤其是对阻止虫害迁移起到非常好的作用。
4、夏季覆盖后起到一种挡光、挡雨、保湿、降温的作用；冬春季覆盖后还有一定的保温增湿作用。
二、遮阳网的保湿原理
1、掩盖遮阳网后，由于降温防风效果，下降了掩盖区空气和外界的沟通速度，就明显进步进步空气相对湿度，中午时，湿度增加值，一 般进步13-17%，湿度高，土壤蒸发量下降，增加了土壤湿度。
2、遮阳网是采用聚乙烯（HDPE）， 高密度聚乙烯、PE、 PB、PVC、回收料、全新料、聚乙丙等为原材料，经紫外线稳定剂及防氧化处理，具用抗拉力强、耐老化、耐腐蚀、耐辐射、轻便等特点。
The shading net can prevent plants from being exposed to strong light, rainstorm, high temperature, and can also hinder the spread of diseases and pests, such as preventing the migration of pests.
Sunshade nets are mainly used in summer, especially in the southern regions where they are widely used. The northern summer is usually covered with white film, while the southern summer is usually covered with black shading nets.
In addition to the above functions, shading nets also have a certain degree of insulation and moisturizing ability.
There are only two types of shading nets, black and gray, with slight differences between the two: black has a high shading rate and good cooling effect, but it has a significant impact on photosynthesis and is more suitable for use on leafy vegetables. If used on some light loving vegetables, the coverage time should be reduced. Although the cooling effect of the silver gray shading net is not as good as that of the black one, it has a relatively small impact on the photosynthesis of vegetables and can be used on light loving vegetables such as eggplants and fruits.
1、 The role of shading nets
1. Sunshade nets are mainly used in summer, especially in the southern region with a large promotion area. Some people describe it as: winter in the north is covered with white film, while summer in the south is covered with black film.
2. The use of shading nets to cultivate vegetables in the south during summer has become a major technical measure for promoting disaster prevention and protection. The application in the north is still limited to summer vegetable seedling cultivation.
3. In summer (June August), the main functions of covering the shading net are to prevent the exposure of the hot sun, the impact of rainstorm, the harm of high temperature, and the spread of diseases and pests, especially to prevent the migration of pests.
4. After covering in summer, it plays a role in blocking light, rain, moisturizing, and cooling; After covering in winter and spring, there is also a certain degree of insulation and humidification effect.
2、 The moisturizing principle of sunshade nets
1. After covering up the shading net, due to its cooling and windproof effect, the communication speed between the air in the covered area and the outside world is reduced, which significantly improves the relative humidity of the air. At noon, the humidity increases by 13-17%, which is generally higher. As the humidity is high, the soil evaporation decreases and increases the soil humidity.
2. The sunshade net is made of polyethylene (HDPE), high-density polyethylene, PE, PB, PVC, recycled materials, brand new materials, polyethylene propylene, and other raw materials. It has been treated with ultraviolet stabilizers and anti oxidation treatment, and has the characteristics of strong tensile resistance, aging resistance, corrosion resistance, radiation resistance, and portability.

止水螺杆使用时的安装间距
我们知道止水螺杆普遍的操作方法是木模板或复合型模版时选用，止水螺杆这一在标准里〈施工工艺〉的规定是常见间隔在400~600，实际的间隔，应当看施工计划设计方案上的要求，由于有的的地区施工单位墙的薄厚非常后，这类状况下止水螺杆间隔就规定就大。实际间隔牵涉到止水螺杆的应用直径、框架柱的高宽比，再开展实际的测算就可以得到。
We know that the common operating method for water stop screws is to use wooden templates or composite templates. In the standard “Construction Technology”, the spacing for water stop screws is usually between 400 and 600. The actual spacing should depend on the requirements of the construction plan design scheme. Due to the extremely thin thickness of the construction unit wall in some areas, the spacing for water stop screws is specified to be large in such situations. The actual spacing involves the application diameter of the water stop screw and the aspect ratio of the frame column, which can be obtained by conducting actual calculations.
pvc管材安装使用方法
PVC管材的安装方法： 1，PVC管在与钢管连接的时候，要先将钢管的连接处擦胶水，将PVC管加热后变软不会烧焦，然后承插在钢管上做降温处理。 2，粘接的时候严禁沾到水，PVC管必须放平在沟内，接头24小时后开始回填，要将管道的四周填紧，接头部位大批量回填。 3，玻璃纤维固化剂配成的树脂溶液浸渍玻璃纤维布之后，均匀缠绕在管道的渗漏出然后固化形成玻璃钢。 4，套补粘接法主要是针对管道小孔和接头的渗漏，选用统一的口径管材将其纵向剖开，然后将管内和外表面打毛，涂胶后在漏水处贴紧。
Installation method of PVC pipes:
1. When connecting PVC pipes to steel pipes, the joints of the pipes should be rubbed with glue first, and the PVC pipes should be heated to become soft without burning. Then, they should be inserted onto the steel pipes for cooling treatment.
2. During bonding, it is strictly prohibited to touch water. PVC pipes must be placed flat in the trench, and backfilling should begin 24 hours after the joint. The surrounding areas of the pipeline should be filled tightly, and the joint parts should be backfilled in large quantities.
3. After the resin solution prepared with glass fiber curing agent is impregnated with glass fiber cloth, it is evenly wrapped around the leakage of the pipeline and then solidified to form fiberglass.
4. The patching and bonding method is mainly aimed at the leakage of small holes and joints in the pipeline. A unified caliber pipe material is selected to longitudinally cut it open, and then the inner and outer surfaces of the pipe are roughened. After applying glue, it is tightly adhered to the leaking area.
钢筋连接套筒和钢筋接头的使用安装方法
一、钢筋连接套筒和钢筋接头的使用安装 1、钢筋就位：将丝头查验合格的钢筋搬运至待联接处。 2、接头拧紧：运用扳手或管钳等东西将联接接头拧紧。 3、作符号：对现已拧紧的接头作符号，与未拧紧的接头区分隔。 4、施工查验：对施工完的接头进行的质量查验。 5、绑扎其它钢筋。 钢筋接头加工的技术是需要十分慎重的进程需要的，我们可以经过比较其他加工技术而言，钢筋接头的技术进程是十分慎重的。
1、 Use and installation of steel bar connection sleeves and steel bar joints 1. Steel bars in place: Transport the steel bars that have passed the wire head inspection to the joint to be connected. 2. Joint tightening: Use a wrench or pipe wrench to tighten the joint. 3. Mark: Mark the joints that have been tightened and separate them from the area of the joints that have not been tightened. 4. Construction inspection: Quality inspection of joints after construction. 5. Bind other steel bars. The technology of processing steel bar joints requires a very cautious process, and we can compare it with other processing technologies. The technical process of steel bar joints is very cautious.
钢筋马镫是做什么用的？
一、提高施工质量 铁马凳的采用，对建筑施工来说，是一种施工技术，因产品为工厂标准化、规格化生产，故其质量比人工制作的马镫更为标准，更加控制板楼下层钢筋保护层的标准性，并有效控制了上下层钢筋的间距。而且通过支架的使用，便于工地施工管理的规范，减少施工随意性。 二、提高施工效率 与传统人工工地现场制作的马镫相比，铁马凳因产品轻巧，安装简便，易于定位，从而减小施工人员劳动强度，通过实际使用情况测算，平均提高现场钢筋施工效率20%左右，在加快了钢筋混凝土施工进度的同时降低了施工成本。并且减少了工地的焊接，有利于提高项目施工的安全性。 三、降低施工成本 铁马凳的使用不仅有效控制工地废料的产生（包括工人现场制作马镫的认为损耗），而且减少了工人现场加工量，节约了工地现场用电量，很大程度降低了生产成本。并且我公司的产品价格比施工现场所用废钢筋制作的铁马凳节约成本30%左右，比用成品钢筋制作的马镫节约成本50%左右，直接降低施工成本。
1、 The use of iron horse stools to improve construction quality is a construction technology for building construction. As the product is standardized and produced by the factory, its quality is more standardized than that of manually made stirrups, which better controls the standardization of the protective layer of the lower steel bars in the slab building and effectively controls the spacing between the upper and lower steel bars. Moreover, the use of brackets facilitates standardized construction management on the construction site and reduces the randomness of construction. 2、 Compared with traditional manual on-site production of stirrups, the iron horse stool reduces the labor intensity of construction personnel due to its lightweight, easy installation, and easy positioning. Based on actual usage, it increases the on-site steel bar construction efficiency by an average of about 20%, accelerating the progress of reinforced concrete construction and reducing construction costs. And it reduces welding on the construction site, which is beneficial for improving the safety of project construction. 3、 The use of iron horse stools to reduce construction costs not only effectively controls the generation of waste materials on the construction site (including the perceived loss of stirrups made by workers on site), but also reduces the on-site processing volume of workers, saves electricity consumption on the construction site, and greatly reduces production costs. And our company’s product price saves about 30% of the cost compared to the iron horse stool made of waste steel bars on the construction site, and about 50% of the cost compared to the stirrup made of finished steel bars, directly reducing construction costs.
