Slope reinforcing retaining wall and construction method thereof
The invention discloses a slope reinforcing retaining wall and a construction method thereof. The retaining wall comprises a concrete cushion and a plurality of unit structural layers formed by a backfill soil layer entraining a concrete soil layer above the concrete cushion. The inclination angle of each unit structural layer is consistent with the grade of the slope. A plurality of hollow steelpipes vertically pressed unto a soil body downward are arranged on the concrete cushion. The hollow steel pipes of same inclination angle are arranged in the unit structural layers. Two ends of the hollow steel pipes are restrained and fixed by concrete soil layers. A base structure of the retaining wall is relatively high in bearing capacity and unlikely to soften and permeate. The unit structural layers are stable structural bodies and have the characteristics of isolating water and being unlikely to soften. The inclination angle of the retaining wall can be arranged relatively steeply, so that the cost of filling engineering is saved. A soil material of the retaining wall is fully taken from an excavated natural soil body, so that the engineering cost can be saved. The slope reinforcingretaining wall is particularly suitable for south region with limited sites for reinforced design of the slope and high perennial rainfall frequency.
本发明公开了一种边坡加筋挡土墙及其施工方法，挡土墙包括混凝土垫层及其上方的水泥土层夹回填土层形成的单元结构层，单元结构层可设置多层，各单元结构层的倾角与边坡坡度一致，混凝土垫层处设置有垂直向下压入土体中的若干空心钢管，单元结构层中设置有同倾角的空心钢管，空心钢管的两端分别通过水泥土层约束固定。挡土墙的基础结构承载力较高、不易软化和渗透，单元结构层为稳定的结构体，具有隔水和不易软化的特点。所以挡土墙面倾角可设置较陡，节省填筑工程两节约成本。挡土墙的土料完全取自开挖的天然土体，可节约工程成本。本发明尤其适用于边坡加固设计场地有限、常年降雨频率大的南方地区。
