Problems solved by technology

[0003] This method is suitable for underpinning of a single piece or wall with moderate thickness and uniform material structure. However, for masonry with relatively large volume, surrounded by bricks, complex internal structure, loose foundation, and uneven material dispersion Structural platform, the above method is difficult to apply

Abstract

The invention provides an integral underpinning method for a discrete type bricking platform. The integral underpinning method specifically comprises the following steps that S1, a platform foundationis surrounded by concrete retaining plates; S2, grouting reinforcement is carried out for the platform foundation at the corresponding position after installing the concrete retaining plates; S3, cross drilling is carried out on the platform foundation after grouting; S4, underpinning profile steel is inserted into the drilled holes, and the two ends of the underpinning profile steel can extend out from the corresponding concrete retaining plates to the outside; and S5, grouting is carried out in the holes in which the underpinning profile steel is placed so as to enable the underpinning profile steel and the platform to form a whole. According to the integral underpinning method, the stability of the platform foundation is increased by grouting the discrete and loose bricking platform foundation, through the insertion of a dense underpinning plate, the structure located above the platform foundation is underpinned integrally, the integral underpinning of the discrete type bricking platform foundation is realized, and the stability of the superstructure of the underpinning platform is guaranteed.

Description

technical field [0001] The invention relates to the field of displacement of existing buildings, in particular to an integral underpinning method for a discrete brick platform. Background technique [0002] In order to displace the existing brick cavity, it is necessary to underpin the brick platform foundation (foundation) to other movable structures. The traditional brick wall usually adopts the underpinning form of double clamped wall beams. The clamped beams are arranged on both sides of the wall, and an underpinning beam is arranged at a certain distance along the wall direction. The underpinning beams connect the clamped beams on both sides and Transverse the wall and transfer the load of the upper wall to the clamped wall beams on both sides. [0003] This method is suitable for underpinning a single piece or wall with moderate thickness and uniform material structure. However, it is suitable for masonry with relatively large volume, surrounded by bricks, complex int...
