High-rise pile cap retaining wall and construction method

Abstract

The invention relates to the field of side slope retaining structures, and discloses a high-rise pile cap retaining wall and a construction method. The high-rise pile cap retaining wall comprises a double-row pile foundation, transverse waist beams, longitudinal waist beams, a pile cap, a corbel, a connection beam, a plug pin, a soil retaining plate, a foundation, an anchor rod, a soil retaining wall, a soil retaining wall back and water leakage holes. The transverse waist beams and the longitudinal waist beams are arranged on the middle portion of the double-row pile foundation. The pile capis connected with the top of the double-row pile foundation. The corbel is connected with the inner sides of the pile cap and the double-row pile foundation. The connection beam is placed on the corbel. The connection beam and the corbel are connected through the plug pin. The soil retaining plate is placed on the connection beam. The foundation and the anchor rod are arranged inside the connection beam. The inner end of the anchor rod is anchored into a stabilization slope body. The outer end of the anchor rod is connected with the connection beam. The soil retaining wall is arranged on the top face of the pile cap. The soil retaining wall back is a graded broken stone reversed filter layer. The water leakage holes formed at certain intervals and penetrating through the pile cap are formed below the soil retaining wall back and the graded broken stone reversed filter layer. The double-row foundation and the pile cap transmit a part of horizontal force into the stabilization slope bodythrough the corbel, the plug pin, the connection beam and the anchor rod, the retaining height of the high-rise pile cap retaining wall is greatly increased, the project cost is reduced, influences on the environment are reduced, and a landscape effect as good as that of a stilted building can be achieved on the aspect of landscapes.

Description

technical field [0001] The invention relates to the technical field of slope retaining structures, in particular to high pile cap retaining walls and construction methods. Background technique [0002] At present, in the field of geotechnical engineering, super-high fill retaining structures suitable for steep ground slopes mainly include ultra-high retaining walls with super-large sections, pile-slab walls, and anchor-cable pile-slab walls, etc., but these retaining structures exist Certain deficiencies, such as super-high retaining walls with super-large sections require a large amount of engineering, high cost, high requirements for foundation bearing capacity, high probability of problems, and high cost of pile-slab walls and anchor-cable pile-slab walls , long construction period, greater impact on the environment, and unsightly facade.

Problems solved by technology

[0003] Technical problem: The purpose of the present invention is to provide a high pile cap retaining wall and a construction method, aiming to solve the problem that the super high retaining wall with a super large section in the prior art has a large amount of work, high cost, and high requirements for the bearing capacity of the foundation. The probability of problems is also high; pile-slab walls and anchor-cable pile-slab walls have high cost, long construction period, great impact on the environment, and unsightly facades, etc.
