Ground uniform settlement structure and construction method

Abstract

The invention discloses a ground uniform settlement structure and a construction method in order to overcome the defects that indoor ground settlement is nonuniform and consequently normal use of buildings is affected. The ground uniform settlement structure comprises engineering piles and cast-in-situ members. Pile end support stands are disposed on the engineering piles; each cast-in-situ member comprises an L-shaped guiding portion and a long strip supporting portion; limiting parts are arranged at the edges, close to the engineering piles, of the supporting portions in a casting mode correspondingly; abutting joint plates which are opposite to the limiting parts are disposed on the upper portions of the pile end support stands on the engineering piles; the outer side faces of the limiting parts are limiting planes; buffer pads are mounted between the limiting planes and the abutting joint plates; the guiding portions are disposed on the outer sides of the pile end support stands; prestress springs are connected between the supporting portions and the pile end support stands; arched reinforcing ribs are disposed between the guiding portions of every two adjacent cast-in-situ members; compacted soil is located under the cast-in-situ members; deep fill soil is buried between the guiding portions of every two adjacent cast-in-situ members; rigid ground is located between the supporting portions of the every two adjacent cast-in-situ members; and inserting ribs are connected between the rigid ground and the supporting portions.

Description

technical field [0001] The invention relates to a building construction technology, more specifically, it relates to a uniform subsidence structure of the floor and a construction method. Background technique [0002] At present, a large area of ​​earth filling is often required for engineering construction on relatively low-lying sites. For pile-based buildings, pile foundations are often set up at the lower part of the main structure such as columns and walls, and the settlement is small. However, indoor floors generally use new For the rigid floor of the filled foundation, when the filling is thick, the settlement is relatively large, and the settlement of the floor near the column and wall is less affected by the pile foundation. Therefore, the indoor floor often has obvious uneven subsidence, which affects normal use of the building. [0003] Chinese Patent Publication No. CN103806435A discloses a floor settlement treatment method and a floor structure, in which a grou...
