对加筋土挡土墙装配单元的要求是,便于安装、垂直度好、加筋后能自身锚定。筒形(箱形)企口式的装配单元(图1)和异形混凝土梁式装配单元(图2)是比较好的一种。装配单元接口处为企口,安装后不会产生错位。箱内填土,下部填砾石以利排水,上部灌筑混凝土。拉筋用聚合材料或旧皮带(输送带)割制。拉筋也可利用渔网,其线径为5～10毫米,网目为50×50到100×100毫米。这种每平方米约100个结的网会在填土中形成分布的锚固体系。网式拉筋与带式拉筋(图3)
Reinforced earth retaining wall assembly unit requirements are easy to install, good verticality, reinforced self-anchored. Cylindrical (box) flapper fitting units (Figure 1) and profiled concrete beam fitting units (Figure 2) are the better ones. Assembly unit interface at the mouth of enterprises, after installation will not produce dislocation. Filling the box, the bottom of the gravel to facilitate drainage, the upper perfusion of concrete. Tendon with polymeric materials or the old belt (conveyor belt) cut. Stretching can also use fishing nets, the diameter of 5 to 10 mm, mesh 50 × 50 to 100 × 100 mm. This net of about 100 knots per square meter forms a distributed anchoring system in the fill. Web-style lacing and band-type lacing (Figure 3)
