Problems solved by technology

[0002] Existing retaining walls are in the form of straight or segmented straight lines on the plane, which is extremely unfavorable for the use of high and large retaining walls, and due to the large thrust of the slope, the retaining walls need to provide corresponding resistance, resulting in this There is an embarrassing situation of high cost for similar retaining walls
[0003] For linear retaining walls, in addition to the characteristics of high cost, its stabilization effect is not good, and engineering accidents often occur
In addition, the "man-made" characteristics of the linear retaining wall are extremely strong, and in many cases it is not well coordinated with the natural environment, and the environmental perception is poor

Embodiment 1

[0025] Project overview: a construction earthwork excavation waste slag field such as figure 1 , figure 2 As shown, the spoil field is a retaining wall in the valley area between two ridges. The design requirements were to control the cost while ensuring safety and to maintain harmony with the environment after the slag was completed.

Embodiment approach

[0027] A horizontal arc-shaped arch retaining wall 2 is set at the narrow part of the valley at the lower part of the site. The arc-shaped central control point of the arc-shaped arch retaining wall 2 is at point A. The structure of the reinforced earth retaining wall is adopted, and the section size is determined by design calculation. and selection of materials; use the slope stable bedrock on both sides of the valley as the end structure 1 of the arc arch retaining wall to provide arch foot resistance for the arc arch retaining wall 2; when applying the end structure 1 of the arc arch retaining wall, remove the ground first The soil mass and strongly weathered rock mass are made into end faces perpendicular to the arc of the arc-shaped arch retaining wall 2; after the construction of the end structure 1 and the arc-shaped retaining wall 2 is completed, a waste slag silo is formed, and then the slag is rolled into the silo in layers. The discarded slag is piled up to the elev...

Embodiment 2

[0039] Project overview: a landslide is located in the valley area between two ridges, and the plane topography is referred to in Example 1. figure 1 and combine image 3 As shown in the figure, the landslide is now to be treated, and the design requirements are to control the cost while ensuring safety, and try not to damage the natural vegetation.

[0040] Embodiment: The method of high-pressure rotary jetting piles is used to form an arc-shaped arch retaining wall 2 composed of a rotary jetting cement-soil structure below the surface of the landslide support position; A certain distance is reserved between the bottom surface of the arch retaining wall 2 and the bedrock surface line 10. In this distance, there is no swirling jet, and only the guide hole of the rotary jetting pile enters below the bedrock surface line 10 to form a groundwater channel; in the arc-shaped arch retaining wall 2 The part where the end is in contact with the bedrock is sprayed locally with ribs, a...

Abstract

The invention provides a horizontal arc-shaped arch retaining wall and an upper arched slope body, which are mainly composed of an arc-shaped arch retaining wall, an end structure and an upper arched slope body. The main retaining structure is the arc-shaped arch retaining wall, and the end structure is connected with the arch foot of the arc-shaped arch retaining wall to transmit its resistance to the stable formation. The upper part adopts a horizontal arched slope to form an overall structure consistent with the lower retaining wall. The advantages of the invention are: the internal force of the retaining wall structure is mainly pressure, and cheap structures and geological materials with good compressive performance can be used to greatly reduce the cost; Construction; reducing or not using large excavation, filling and pile and anchor structure system, fast construction, high practicability; good overall stability of the structure; good coordination with the natural environment, with excellent market prospects and social benefits.

Description

technical field [0001] The invention belongs to the technical field of side slope engineering, and particularly relates to a horizontal arc-shaped arch retaining wall and an upper arched slope body using the arc-shaped arch retaining wall. Background technique [0002] The existing retaining walls are in the form of straight line or segmented straight line distribution on the plane, which is extremely unfavorable for the use of high and large retaining walls, and due to the large thrust of the slope, the retaining wall needs to provide corresponding resistance, resulting in this problem. There is an embarrassing situation in which the cost of quasi-retaining walls remains high. [0003] For linear retaining walls, in addition to the characteristics of high cost, the stabilization effect is not good, and engineering accidents often occur. In addition, the "man-made" characteristics of the linear retaining wall are extremely strong, and in many cases, the coordination with th...
