Building ground surface settlement repair method

Abstract

The invention discloses a building ground surface settlement repair method. The method is characterized by comprising the following steps that S1, a road breaker is used for breaking the portion, where settlement occurs, of the building ground surface, original filler of the settlement portion is removed, then the concrete surface on the inner side wall of a foundation pit formed when the settlement portion is broken is cleaned, grinding is performed when necessary, and repair should be performed in advance if honeycombs or holes exist; and S2, after the inner side of the foundation pit is cleaned, surveying and setting out are performed. Through pile foundations, spurs, connecting shafts, a division wall, automatic repair bags, a metal binding wire net and clamp nuts which are designed, the problems that an existing building ground surface settlement repair method is mostly a layer-to-layer overlay filling method, a flaking phenomenon is prone to occurring between layers, the stability after the building ground surface repair is severely affected, in addition, the water proof performance is poor, automatic repair fails when an internal waterproof structure is damaged, and the service life of the building ground surface which is repaired is severely shortened are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction methods, and in particular relates to a method for repairing building surface settlement. Background technique [0002] Under the action of building load, the vertical deformation or subsidence of foundation soil due to compression. Uniform settlement is generally less harmful to buildings, but if it is too large, it will also reduce the elevation of the building and affect its use. When designing the foundation, the settlement should be estimated. [0003] Uneven settlement is very harmful to buildings. It will cause additional stress in the building, cause cracks, and even break local components, endangering the safety of buildings. , can not meet the demand of production. [0004] The existing building surface settlement repair methods are mostly covering filling between layers, which is prone to shelling between layers, which seriously affects the stability of the building sur...

[0003] Uneven settlement is very harmful to buildings. It will cause additional stress in the building, cause cracks, and even break local components, endangering the safety of buildings. , cannot meet the demand of production

[0004] The existing building surface settlement repair methods are mostly covering filling between layers, which is prone to shelling between layers, which seriously affects the stability of the building surface after repair, and the waterproof performance is poor. When the interior When the waterproof structure is damaged, it cannot be repaired automatically, which seriously shortens the service life of the repaired building surface. Therefore, we propose a repair method for building surface settlement
