An assembled anti-seismic anchor retaining wall and its construction method

Abstract

The invention discloses a novel fabricated anti-seismic anchor retaining wall. The novel fabricated anti-seismic anchor retaining wall comprises a retaining wall body and an inverted filter layer. Theinverted filter layer is arranged on the back of the retaining wall body. The retaining wall body comprises n retaining plates and (n-1) anti-seismic plates. The retaining plates and the anti-seismicplates are arranged at intervals. Connecting assemblies are installed between the anti-seismic plates and the retaining plates. Joint filler is arranged between the retaining plates and the anti-seismic plates in a filling mode. A plurality of bidirectional dampers are arranged in the anti-seismic plates. The bidirectional dampers are arranged vertically. Every two of the bidirectional dampers are arranged in an included-angle mode. The bidirectional dampers which are arranged in an intersection angle mode can counteract the force in different directions, so that a load-bearing wall body is prevented from deforming and fracturing, the integrity of the retaining plates is maintained, and a good anti-seismic effect is achieved; prefabricated shell structures are adopted for the outer wallsof the retaining plates and the anti-seismic plates, transportation and hoisting are facilitated, and the transportation cost is saved; and the retaining plates and the anti-seismic plates are connected by the connecting assemblies, the structure is simple, the connection is convenient, the installation is convenient, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of retaining walls, in particular to an assembled anti-seismic anchor retaining wall and a construction method thereof. Background technique [0002] The anchor retaining wall is a lightweight retaining structure composed of reinforced concrete columns, retaining plates and anchors. The anchors are connected to the columns. The earth pressure behind the wall is transmitted to the columns by the retaining plates. The anchoring force between the bodies stabilizes the walls. Its structure is light and the cost is low, so it is suitable for important projects with low foundation bearing capacity, but the construction technology is complicated and the seismic performance is poor. There are through cracks, overall collapse, and it is difficult to repair, which not only affects the normal use and function of the anchor retaining wall, but also causes deformation and instability of the supported slope, affects peop...

Its structure is light and the cost is low, so it is suitable for important projects with low foundation bearing capacity, but the construction technology is complicated and the seismic performance is poor. There are through cracks, overall collapse, and it is difficult to repair, which not only affects the normal use and function of the anchor retaining wall, but also causes deformation and instability of the supported slope, affects people's normal production and life, and even causes huge damage to people's lives and property. loss
