Problems solved by technology

[0004] Disadvantages: The woven bag used to wrap and fix the geogrid is easy to age and cause soil loss and uneven slope
If there is no slope greening, the slope will be relatively monotonous

Embodiment Construction

[0016] Root attached figure 1 . figure 2 As shown in (1) first, if the bearing capacity of the shallow part of the foundation does not meet the requirements, replace it first, then level it up to the design elevation, lay a layer of geogrid + graded gravel cushion on the ground ⑥, and pour C15 concrete Cushion layer ⑤, and then start to make concrete ground beams ④. The height of the ground beams is required to be slightly higher than that of the first layer of grids. The geogrid is compressed and fixed with bagged gravel, and the pre-embedded steel bar ③ is placed on the top, and the front end of the steel bar is made into a hook; (2) After the geogrid is laid to a certain height, the concrete panel ① is started on the ground beam, The pre-placed steel bars are connected with the panel steel bars (main bars, tie bars ②), and at the same time, they are used as concrete formwork fixing measures.

Abstract

The invention discloses a technology for processing a soil filled slope by combining geogrids and concrete panels. The technology comprises the following steps of: flattening to a foundation design elevation, paving a layer of broken stone hardcore on ground, and manufacturing a concrete ground beam, wherein the height of the ground beam is required to be greater than that of a first layer of grinds; after the age of the pouring of the ground beam is reached, paving the geogrids inside the ground beam, and laminating on different layers; placing embedded bars on the top of each layer of the geogrids, and manufacturing bent hooks at the front ends of the steel bars; after the geogrids are paved for certain height, starting to manufacture the concrete panels on the ground beam; and connecting the steel bars which are placed in advance and the steel bars of the panels, wherein the step of connecting the steel bars which are placed in advance and the steel bars of the panels is used as fixing measures of a concrete formwork.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, and relates to a technology for treating fill slopes by using a geogrid combined with a concrete cast-in-place panel. Background technique [0002] Common forms such as gravity retaining wall, anchor plate retaining wall, anchor retaining wall, reinforced concrete cantilever retaining wall, and reinforced soil retaining wall are generally used to deal with the fill slope. Gravity retaining walls rely on the wall's own weight to support the earth pressure to maintain its stability. Generally, pieces (blocks) of stone are used for masonry, the form is simple, and local materials can be obtained. However, the stability of the entire wall depends on the concrete wall resisting the earth pressure and bending moment generated by the filling, and the general cross-sectional size is large. [0003] For the filling slope, the construction of geogrid is relatively simple, the requirement...
