塑料土工格栅如何加筋扶壁式挡墙

       塑料土工格栅是经过拉伸形成的具有方形或矩形的聚合物网材，按其制造时拉伸方向的不同可为单向拉伸和双向拉伸两种。它是以聚丙烯为主要材料，通过挤出、然后再纵向、横向拉伸形成的一种gq度土工材料。

       Plastic geogrid is a kind of polymer net material with square or rectangle formed by stretching. It can be divided into unidirectional stretching and biaxial stretching according to the different stretching direction when it is manufactured. It is a kind of high-strength geotechnical material which is made of polypropylene by extrusion, then longitudinal and transverse stretching.

       塑料土工格栅是适用于公路及铁路路基、路堤、边坡加筋、各类挡墙加筋、江河海坝的加筋及堆场加筋、桥台加筋、较前层基础的加筋。广泛应用于各类加筋挡土墙。双向格栅适用于公路及铁路路基、路基加筋、防止沥青混凝土路而反射裂缝等。广泛应用于路基、路堤加筋和浅层基础加筋。

Plastic geogrid is applicable to the reinforcement of subgrade, embankment, slope, retaining wall, river and sea dam, storage yard, abutment and foundation. It is widely used in all kinds of reinforced retaining walls. The two-way grid is suitable for highway and railway subgrade, subgrade reinforcement, preventing reflection crack of asphalt concrete road, etc. It is widely used in subgrade, embankment reinforcement and shallow foundation reinforcement.

       在建筑工程施工当中,经常会遇见诸多边坡需要支护的问题,特别是一些高填深挖的边坡。而现有技术中,支挡结构主要有重力式挡墙、悬臂式挡墙、扶壁式挡墙、锚杆式挡墙等。对于重力式挡墙,其稳定性的来源主要靠墙身自重,这种挡墙截面较大、浪费材料,不经济，且只用于低矮边坡加固;悬臂式挡墙适用于6~9m,随着墙身z,墙板变形z,且钢筋用量急剧增加,不经济;扶壁式挡墙由墙面板(立壁)、墙趾板、墙踵板及扶肋(扶壁)组成。

In the construction of construction projects, there are often many problems that need to be supported, especially some high fill and deep excavation slopes. In the existing technology, the retaining structure mainly includes gravity retaining wall, cantilever retaining wall, buttress retaining wall, anchor rod retaining wall, etc. For gravity retaining wall, its stability mainly depends on the self weight of the wall body. This kind of retaining wall has a large section, wastes materials, is not economical, and is only used for the reinforcement of low slope; cantilever retaining wall is suitable for 6-9M, with the increase of the wall body, the deformation of the wall plate increases, and the amount of reinforcement increases rapidly, which is not economical; buttress retaining wall is composed of wall panel (vertical wall), wall toe plate, wall heel plate and rib (buttress).

        扶肋把墙面板同墙踵板连接起来,起加劲的作用,以改善立壁和墙踵板的受力条件,提高结构的刚度和整体性，一般适用9~12m,但是随着高度增加,钢材的用量迅速增加，影响经济性;并且由于墙后坡料中的水分不能及时排除,从而会使造成结构自身受额外的静水压力,粘性土填料因含水量增加产生膨胀压力,季节性冰冻地区填料的冻胀压力,均会造成支挡结构的AQ性能受到影响。

The rib connects the wall panel with the wall heel plate, and plays a role of stiffening, so as to improve the stress conditions of the vertical wall and the wall heel plate, improve the rigidity and integrity of the structure. Generally, it is applicable to 9-12M, but with the increase of the height, the consumption of steel increases rapidly, which affects the economy; and because the moisture in the slope material behind the wall cannot be removed in time, it will cause the structure itself to suffer additional hydrostatic pressure, Because of the increase of moisture content, the swelling pressure of cohesive soil filler and the frost heaving pressure of filler in seasonal frozen area will affect the safety performance of retaining structure.

       塑料土工格栅加筋扶壁式挡墙,包括趾板、踵板、墙面板和扶壁,所述踵板地面设置有凸榫,所述扶璧沿墙面板长度方向设置为多个,所述墙面板的下端设置有排水孔,所述排水孔为多个且沿墙面板的长度方向设置,通过在扶壁墙的墙背通过连接固定件连接塑料土工格栅进行填土加筋处理，减轻填土侧滑,改善墙面板的受力情况,使得同等尺寸的挡土墙具有更高挡土强度，并且通过排水孔和盲沟的设置,以疏干仓格内和墙后坡料中的水分,消除粘性土填料因含水量增加产生的膨胀压力,保证高填土支挡结构的AQ性,通过使用塑料土工格栅,能够与环境协调一致且适用于高填方,结构简单，施工快速,工程造价低。

Plastic geogrid reinforced buttress retaining wall, including toe board, heel board, wall panel and buttress wall, the heel board ground is provided with tenon, the buttress wall is provided with multiple along the length direction of the wall panel, the lower end of the wall panel is provided with drainage holes, the drainage holes are multiple and along the length direction of the wall panel, The back of the buttress wall is connected with the plastic geogrid by connecting the fixed parts to reinforce the earth, so as to reduce the side slip of the earth and improve the stress of the wall panel, so that the retaining wall of the same size has higher retaining strength, and through the setting of drainage holes and blind ditches, the water in the warehouse lattice and the slope material behind the wall is drained, To eliminate the expansion pressure of cohesive soil filler due to the increase of water content, to ensure the safety of high fill retaining structure, through the use of plastic geogrid, it can be consistent with the environment and suitable for high fill, simple structure, rapid construction, low project cost.

       相信大家看完以上内容以后，应该也对塑料土工格栅如何加筋扶壁式挡墙有所了解了，希望会对大家有所帮助吧。
