Miniature adjustable steel inner pile sleeved pile

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a miniature adjustable steel inner pile sleeved pile which comprises an outer sleeve, an inner pile and a steel ring plate. Sliding grooves are evenly formed in the upper surface of the steel ring plate, and are annularly arranged at equal intervals with the center line of the steel ring plate as the axis; sliding rods are slidably connected into the sliding grooves; arc-shaped blocks are fixedly connected to the ends, away from the inner pile, of the sliding rods; through holes are formed in the middles of the arc-shaped blocks; one same reinforcing steel bar is arranged in the through holes among the multiple arc-shaped blocks in the vertical direction; guide rods are fixedly connected to the upper surfaces of the sliding rods; the upper surface of the steel ring plate is rotationally connected with an adjusting plate; the adjusting plate is annular; arc-shaped grooves which are uniformly distributed are formed in the adjusting plate; the arc-shaped grooves are obliquely designed; and the guide rods slide in the arc-shaped grooves. According to the miniature adjustable steel inner pile sleeved pile provided by the invention, the size of the steel ring plate is adjusted, the construction efficiency is improved, the overall connection strength of a pile body is improved, the pile body is prevented from being deformed and damaged, and the service life of the pile body is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a miniature adjustable steel inner pile casing pile. Background technique [0002] Mini casing pile is a new type of pile, which can ingeniously isolate side resistance and effectively solve the problem of ground expansion and contraction. Different from traditional piles, micro-cased piles mainly include inner piles and outer casings. The upper end of the outer jacket is located in the swelling and shrinking soil layer, and the bottom is supported on the stable soil layer. The inner pile is fixed by pouring concrete at the bottom of the pile. There is an overhead height and the building is built above the inner pile. Since there is a cavity between the inner pile and the outer casing, when the soil layer expands and contracts, friction is applied to the outer casing to drive the outer casing to move to a certain extent, thereby effectively eliminating the soil laye...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the shortcomings of the existing technology and solve the poor connection strength between multiple rigid ring plates in the prior art, when some steel ring plates are damaged, the pile body is easily deformed and damaged due to excessive local force, reducing the use of the pile body The service life is low, and due to the different sizes between the outer casing and the inner pile in different construction sites, the steel ring plate needs to be customized in advance or processed on site, which makes the construction efficiency low. The present invention proposes a miniature adjustable steel inner pile Cased pile
