Problems solved by technology

However, since the retaining wall and the anti-slide pile belong to the rigid support structure, the allowable deformation is small when the external load increases sharply, especially under the action of sudden load (earthquake, landslide, etc.), brittle failure is easy to occur. resulting in project failure

Embodiment Construction

[0041] A large deformation buffer transition device for slope support, the device includes:

[0042] Constant resistance structure, frame structure, pressure monitoring module;

[0043] The constant resistance structure is a structure formed by connecting steel plates with a triangular prism-shaped exterior, and its interior is filled with asphalt concrete 6 and prefabricated concrete blocks 5 in layers. The top surface of the prefabricated concrete block 5 contacts the bottom surface of the asphalt concrete 6. Both sides of the concrete block 5 are in close contact with the steel plate, as shown in Figure 5(b).

[0044] The frame structure 4 is constructed of steel plates and solid steel pipes, and is used to place a constant resistance structure in layers. The angle steel 15 constitutes the frame body by welding or riveting, and the steel plates 16 are fixed to the frame body in layers by bolts or welding. Inside. The structural diagram of frame structure 4 is as follows ...

Abstract

A large deformation buffer transition device for slope support, the device includes: a constant resistance structure, a frame structure, and a pressure monitoring module. The constant-resistance structure is a structure formed by connecting steel plates with a triangular prism-shaped exterior, and its interior is filled with asphalt concrete and prefabricated concrete blocks in layers. The top surface of the prefabricated concrete block is in contact with the bottom surface of the asphalt concrete. In close contact with the steel plate. The frame structure is used for layering the constant resistance structure. The pressure monitoring module includes a pressure sensor embedded in the asphalt concrete, and the pressure sensor is connected with a pressure monitor. The device of the present invention is arranged at the rear of the retaining wall or the anti-slide pile, and its rigidity is similar to that of the support structure, and absorbs the energy generated by the sudden increase of part of the external load through constant resistance, and transmits the remaining load evenly to the retaining wall, Or anti-slide piles, thereby effectively avoiding brittle failure of the support structure under sudden dynamic loads and large deformations.

Description

technical field [0001] The invention relates to the technical field of slope support, in particular to a large deformation buffer transition device for slope support. Background technique [0002] Slopes generally exist in human construction projects and daily life, and are a kind of widely distributed geological and landform environment. Deformation and damage usually occur under the influence of human disturbance and natural factors. Natural disasters such as landslides, collapses, and debris flows pose varying degrees of threat to human life and property. Therefore, taking stability as the starting point, taking into account the hydrology, engineering geological conditions, and geological structure of the site, economical and reasonable support measures are adopted to ensure the safety and reliability of slope engineering. Retaining walls and anti-slide piles are common slope support measures, which are widely used in engineering because of their simple structure and con...
