Problems solved by technology

The disadvantage is that the stability and durability of the roadbed are poor: 1. The same wall panel is not firm between the wall panels, and the stability and durability are poor; 2. The wall panel and the filling are not firm, and the stability and durability are poor; 3. Just a wall

Embodiment Construction

[0012] Such as figure 1 , figure 2 , image 3 As shown, the inter-anchored thin-walled retaining wall is mainly composed of retaining panels, tie bars and fillers. The inner side of the retaining panel 3 is provided with a pull ring 8, and its side is provided with an anchor ring 7; the retaining panel is connected to the surrounding The adjacent soil retaining panels are anchored by the connectors and the anchor rings on the contacting sides, and the soil retaining panels are arranged vertically and upwardly from the foundation 1 to form two walls 2; the corresponding soil retaining panels on the two walls at the same height are composed of tension bars 5 is fixed to the pull ring and anchored by opposite pull, the filler 4 is between the two walls, and the pavement layer 6 is on the top.

[0013] The tie bars are steel bars.

[0014] The filler is soil or stone.

[0015] The connectors are anchor bolts (such as Figure 4 shown).

[0016] The soil retaining panel is a ...

Abstract

A mutually anchored thin-wall retention wall for high-filling road embankment is composed of retention slabs, tie bars and filler. Said retention slab has pull rings on its internal surface and anchor rings on its side edges for anchoring several retention slabs together to form two vertical walls. The filler is filled between said two walls to form a pavement layer on its top. Its advantages are high stability and durability, greatly decrease the cubic metre of filled earth and stone, and less possessed agricultural field.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a retaining wall of a high-fill embankment. Background technique [0002] With the development of transportation in our country, there are more and more projects to build high-grade roads or expressways in mountainous areas, and the height difference between different road sections is quite large, so there will be a large number of high-fill embankment projects. In order to obtain a high embankment embankment with stable structure and durable use, reinforcement measures are often required. The current reinforcement measures mainly adopt retaining walls, and the existing retaining walls usually adopt anchor slab structures or reinforced soil structures, such as patent application number 94100288.8, "Anchor slab reinforced soil structures and their construction methods", published " An anchor plate reinforced soil structure is characterized in that each unit is composed of ...
