Problems solved by technology

The retaining wall is usually a reinforced concrete structure, which has two disadvantages: first, laying reinforced concrete requires a large number of mechanical equipment to tamp the soil layer of the slope and harden the slope body, so the amount of work is large, and the environmental coordination performance of the reinforced concrete structure is extremely poor
The retaining wall has three defects: first, it is fixedly installed on the slope, so it can only be used once
Third, the retaining wall structure also retains structures such as diversion pipes to provide conditions for plant growth, and both the design structure and the construction method are relatively complicated

Embodiment 1

[0119] Such as Figure 1 to Figure 4 Shown, design a kind of prefabricated ecological retaining wall of the present invention.

[0120] figure 1 It is a schematic diagram of the overall structure of the prefabricated ecological retaining wall, figure 2 yes figure 1 A partial enlargement of the . The prefabricated ecological retaining wall is a strip-shaped trapezoidal platform structure in which multiple layers of monomers 1 are overlapped and assembled into one. The monomers 1 are fixedly connected; the main body of the monomer 1 is a trapezoidal platform-shaped steel frame 11, and the steel frame 11 is filled with two layers of matrix. The inner layer is a counterweight matrix layer 12, and the outer layer is an ecological matrix layer 13.

[0121] The steel frame 11 adopts a cross grid steel frame. Steel frame 11 steel bars adopt round steel, H-shaped steel, angle steel, channel steel all can. In order to save material cost, there is no ecological matrix layer 13 on ...

Embodiment 2

[0125] Such as Figure 4 As shown, combined with the site conditions, the safety check calculation of the prefabricated ecological retaining wall designed in Example 1 is carried out.

[0126] 1. Wall anti-slip stability checking calculation

[0127] Step S11, on-site investigation to determine the basic parameters

[0128] The basic parameters include the basic parameters of the slope body and the structural design parameters of the prefabricated ecological retaining wall. The structural design parameters of the prefabricated ecological retaining wall are shown in Example 1. The basic parameters of the slope include the statistical average values ​​of various soil parameters x multiple investigation and measurement results u x with standard deviation σ x ,As shown in Table 1. Figure 4 It is a schematic diagram of the meaning of the basic parameters of some slopes and a force analysis diagram of the retaining wall.

Abstract

The invention discloses a fabricated ecological retaining wall and a safety checking calculation method thereof, and aims at the defects of extremely poor environmental coordination performance or increased construction procedures, long construction period and difficulty in total cost control in the prior art. The retaining wall is of a strip-shaped trapezoidal table structure formed by overlapping and assembling multiple layers of single bodies into a whole, the single bodies are fixedly connected, each single body main body is a trapezoidal table-shaped steel frame, the steel frame is filledwith two layers of substrates, the inner layer is a balance weight substrate layer, the outer layer is an ecological substrate layer, and the ecological substrate layer takes porous concrete as a framework, and plants can grow on the ecological substrate layer. The invention further provides a checking calculation method for design safety of the retaining wall. The safety checking calculation isachieved from the four aspects, specifically, anti-sliding stability, anti-overturning stability, foundation bearing capacity safety and bolt shear resistance and tensile bearing capacity safety; andthe retaining wall has high environmental coordination, is economical in material processing and mounting cost, is flexible and convenient to combine and use on site, and has high applicability in various slope disasters and disaster hidden danger places.

Description

technical field [0001] The invention relates to a device for prevention and control of geological disasters, in particular to a wall structure used for slope disasters and a safety checking method thereof, belonging to the technical field of geological disaster prevention engineering. Background technique [0002] Slope disaster is one of the types of geological disasters induced by the comprehensive influence of various environmental factors. It is not only a single type of geological disaster, but also a derivative disaster form of various types of geological disasters, so it has the characteristics of frequent occurrence and dispersion. Regardless of the type and scale of slope disasters, it is a geological problem caused by the sliding movement of the soil above the slope surface along the sliding surface, and the key disaster area is the slope foot area. The "blocking" measure is one of the main preventive measures in slope geological disasters. [0003] The main devi...
