Problems solved by technology

[0003] The existing slope protection systems are mainly passive protection structures such as gravity retaining walls and anti-slide pile retaining walls, and active protection structures with frame retaining walls and anchor rods, but both protection systems are difficult to effectively resist earthquakes.
Under the earthquake state, the passive protection structure cannot effectively control the vibration of the slope and the deformation of the rock and soil mass, and it is very easy to cause the rock and soil mass to collapse and slide
Although the active protective structure has the ability to control deformation, it does not have the anti-seismic characteristics. Under the earthquake, the stress of the anchor rod increases sharply, which will cause the anchor head to fall off, the pressure platform to be crushed, the anchor rod to break, and the anchor to be pulled out. The structure of the rigid frame retaining wall will be void, brittle fracture, etc., which will cause the failure of the active protection system

Embodiment 1

[0047] like Figure 1-5, as shown in 7-8, a construction method of a rigid-flexible economical slope anti-seismic supporting structure, the rigid-flexible economical slope anti-seismic supporting structure includes a rigid supporting structure 1 and a flexible supporting structure 2; The protective structure 1 includes a traditional bolt 4 and a rigid frame structure 3; the flexible supporting structure 2 includes a seismic bolt 6 and a flexible frame structure 5; the seismic bolt 6 includes an anchor a61, a backing plate a63, a protective shell 64, and a rod body a65 and the anti-vibration device 62 located on the backing plate a63; the anti-vibration device 62 includes a spherical roller bearing 621, an arc-shaped limb 622, and a spherical base 623. The inner edge of the spherical roller bearing 621 is fixedly connected with the outer edge of the anchor a61, the outer edge of the spherical roller bearing 621 is evenly distributed with several arc-shaped claws 622, and the in...

Embodiment 2

[0062] The construction method of the rigid-flexible economical slope anti-seismic support structure is the same as that of Embodiment 1. Further, the number of the rod bodies a65 is 3, but in step 8, when the anti-seismic anchor rods 6 are tensioned and locked, due to the construction technology or Due to the influence of construction quality, there is a small difference in the prestress loss of each rod body a65, resulting in unbalanced prestress of each rod body a65, such as Image 6 As shown, when the prestress of the rod body a65 is unbalanced, the anchoring device a61 flips slightly, one end of the larger prestressed rod body a65 sinks, and part of the prestress is released, while one end of the smaller prestressed rod body a65 rises, which is equivalent to applying Part of the prestress is removed. When the prestress of each rod body a65 is the same, the anchorage a61 will no longer be turned over, and a new state of mechanical equilibrium will be reached. The outer edg...

Abstract

The invention discloses a construction method of a rigid-flexible economical slope anti-seismic support structure, comprising a rigid support structure and a flexible support structure; the rigid support structure includes a rigid frame structure and a traditional anchor rod; the flexible support structure includes Flexible frame structures and seismic anchors. The construction methods are as follows: 1 slope repair; 2 lofting; 3 traditional bolt construction; 4 seismic bolt construction; 5 rigid frame structure construction; 6 flexible frame structure construction; 7 traditional bolt tension locking; 8 seismic bolt tension locking . The invention effectively solves the problems of the traditional passive protection structure, which has poor deformation control ability, the active protection structure has no seismic performance, is prone to anchoring failure, and the frame retaining wall is hollowed out and fractured under the action of earthquake. , The bolt stress balance adjustment, can effectively control the slope displacement, has a wide range of application prospects and significant economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of side slope reinforcement, and in particular relates to a construction method of a rigid-flexible and economical side slope seismic support structure. Background technique [0002] my country's geographical location is relatively special. It is located between the Pacific Ring Seismic Belt and the Asia-Europe Seismic Belt. As a result, earthquake-induced landslide disasters occur from time to time. [0003] The existing slope protection systems are mainly passive protection structures such as gravity retaining walls and anti-sliding pile retaining walls, and active protection structures with frame retaining walls and anchors, but both protection systems are difficult to effectively resist earthquakes. Under the earthquake state, the passive protective structure cannot effectively control the slope vibration and the deformation of the rock and soil mass, and the rock and soil mass is prone to collapse and ...
