Abstract
The invention relates to a non-excavation cantilever retaining wall with an embedded steel pipe and a construction method of the non-excavation cantilever retaining wall, and belongs to the technical field of civil engineering. The non-excavation cantilever retaining wall with the embedded steel pipe is composed of a steel pipe reinforced concrete base plate and a reinforced concrete vertical plate. The steel pipe reinforced concrete base plate comprises the hollow steel pipe, a reinforcement cage and concrete with which the hollow steel pipe is filled. The two ends of the hollow steel pipe are open. The reinforced concrete vertical plate is composed of a reinforcement cage and concrete. The inner wall of the hollow steel pipe is coated with lubricating oil in advance, and the hollow steel plate is horizontally embedded into soil in an opening pipe tamping manner. A soil core in the pipe is removed after the hollow steel pipe reaches the target position, the reinforcement cage is placed in the hollow steel pipe and the concrete is poured. The reinforced concrete vertical plate is vertically arranged, a water drainage hole is reserved in the vertical plate, and the steel pipe reinforced concrete base plate and the reinforced concrete vertical plate are connected through the reinforcement cages into a whole. The non-excavation cantilever retaining wall is simple in structure, saves cost, and is convenient to construct, clear and reliable in force transfer, capable of bringing strength characteristics of materials into full play, and applicable to civil engineering of management of geological disaster, slope support and the like.
Description
technical field [0001] The invention relates to a steel pipe embedded non-excavation cantilever retaining wall and a construction method thereof, belonging to the field of civil engineering. Background technique [0002] The cantilever retaining wall is composed of a base plate and a straight wall fixed on the base plate, and the stability of the retaining wall is mainly maintained by the weight of the fill on the base plate. The cantilever retaining wall has a simple structure and can adapt to soft foundations. The wall height is generally between 6m and 9m. The traditional construction method of the cantilever retaining wall is to first excavate the original site soil, level the foundation, then construct the floor and wall, and then backfill and compact the soil. When the amount of excavation is large, especially when the excavation soil itself has a good structure, the traditional construction method is expensive, laborious and time-consuming. [0003] Regarding the re...
