In-hole point anchor slide-resistant pile barricade

Abstract

The invention belongs to the field of slope treatment and discloses a novel in-hole point anchor slide-resistant pile barricade. The in-hole point anchor slide-resistant pile barricade comprises a slope top, slide-resistant piles, point anchors, anchorage sections and horizontal slumping arches, wherein the slide-resistant piles are arranged between the slope top and a slope bottom; anchor cables are disposed on the surfaces of the slide-resistant piles at intervals; one end of each anchor cable is provided with one anchorage section; the point anchors are disposed between the anchor cables and the slide-resistant piles; the horizontal slumping arches and vertical slumping arches are disposed between the point anchors; and a sliding fracture surface is disposed between the anchorage sections and the anchor cables, and the anchorage sections are arranged inside the sliding fracture surface. An in-pile point anchor technology combines the advantages of both a piled anchor method and a point anchor method, the structure safety can be ensured in the construction period, and the construction cost of the projects can be reduced; the novel in-hole point anchor slide-resistant pile barricade has the same construction method as that of a traditional piled anchor system; the structure of each pile body is small in size, the number of steel bars is small, the construction cost is low, and the construction period is short; and the defect that traditional point anchor support methods do not have vertical supports is avoided.

Description

technical field [0001] The invention relates to a retaining wall, in particular to a novel point-anchored anti-sliding pile retaining wall in a hole. Background technique [0002] As we all know, today, the difficulties faced by slope engineering design are: 1) In urban construction, the limitation and complexity of environmental conditions have increased significantly; 2) Due to the limitation of environmental conditions, geological conditions are not selective; Increased restrictions on catastrophic environments such as shocks. Under these conditions, the design of slope engineering has become very difficult. Anti-slide piles are piles that penetrate the slope and go deep into the sliding bed to support the sliding force of the sliding body and stabilize the slope. It is mainly to use the anchor pipe effect and passive resistance of the stable rock formation below the sliding surface of the landslide to balance the sliding thrust of the landslide. With the occurrence of ...

Problems solved by technology

With the occurrence of earthquakes in our country more and more frequently, various slope geological disasters caused by earthquakes have also become more and more frequent, and landslide control has become an increasingly important project. Compared with other anti-slide projects, such as anti-slide Compared with sliding retaining walls, anchor rods, etc., anti-slide piles have the characteristics of strong sliding resistance and wide ap
