Assembly type low pile bearing platform revetment suitable for muddy foundation and construction method

Abstract

The invention discloses an assembly type low pile bearing platform revetment suitable for a muddy foundation. The assembly type low pile bearing platform revetment comprises a pile foundation and a prefabricated bottom plate, wherein a plurality of bottom plate holes are formed in the prefabricated bottom plate, pile heads penetrate through the bottom plate holes, the prefabricated bottom plate iserected on pile foundation brackets, grooves in the side portions of the pile heads are located above the prefabricated bottom plate, fasteners are installed at the positions of the grooves in the two sides of the pile heads and are in an L shape, the lower portions of the fasteners protrude outwards to form fastener tenons, the fastener tenons are tightly attached to the grooves in the side portions of the pile heads, the bottoms of the fasteners abut against the bottom plate, pile head sleeve pieces are arranged on the periphery of the pile heads and the periphery of the fasteners in a sleeving mode, and effective connection between the prefabricated pile foundation and the prefabricated bottom plate is formed. The assembly type low pile bearing platform revetment is reliable in structure, components can be dismantled in order according to needs, waste concrete is not left in soil, the influence on ecology is reduced, factory standard prefabrication is adopted, the cost is low, theuniversality is good, the site cast-in-place concrete construction step is completely avoided, the site construction period is shortened, the construction quality is good, and the environmental influence is small.

Description

technical field [0001] The invention relates to the technical field of river channel engineering construction, and discloses an assembled low-pile cap bank revetment suitable for muddy foundations and a construction method. Background technique [0002] When building revetment works on river courses, there is often a large height difference between the river bed and the rear land area, and the space for grading is small. It is necessary to build vertical revetment sections or composite revetment sections, and erect revetment sections on muddy ground with poor mechanical indicators. Type revetment structure, in order to ensure the safety and stability of the structure, it is necessary to carry out foundation treatment or adopt a deep foundation structure. [0003] Conventional vertical revetment or composite revetment have gravity retaining wall structure, pile cap retaining wall structure, etc., to build a new gravity retaining wall structure on a foundation with deep silt a...

AI Technical Summary

Problems solved by technology

[0003] Conventional vertical revetment or composite revetment have gravity retaining wall structure, pile cap retaining wall structure, etc., to build a new gravity retaining wall structure on a foundation with deep silt and poor foundation bearing capacity, a large-scale foundation is required processing, which is not economical compared to the pile-based structure

The construction of conventional pile cap retaining walls often requires cast-in-place concrete components below the water level, the construction interface is large, the construction period is long, and cofferdams need to be filled to occupy the river for a long time
