Strengthening and deviation rectifying equipment for grouting composite foundation

Abstract

The invention relates to reinforcing and deviation rectifying equipment for a grouting composite foundation. The reinforcing and deviation rectifying equipment for the grouting composite foundation comprises a drill floor arranged on the foundation, a drill bit rod penetrating through the drill floor and entering a foundation soil layer, a drill bit body arranged at the end, located in the foundation soil layer, of the drill bit rod and used for foundation pile hole forming, a guiding stand column arranged on the drill floor, a power device arranged on one side of the guiding stand column and driving the drill bit rod to rotate so as to drive the drill bit body to rotate, a vertical moving device arranged on the guiding stand column and driving the drill bit rod to move in the length direction of the guiding stand column, a grout jetting ring block arranged at the end, close to the drill bit body, of the drill bit rod and capable of jetting grout towards the inner wall of a foundation pile hole, an outer sleeve sleeving the drill bit rod, a grout inlet ring block arranged on the outer sleeve and communicating with the grout jetting ring block in a sealed rotating mode and a soil discharging device arranged on the drill bit rod and used for discharging soil in the foundation pile hole when the drill bit body works. The effect that the grout jetting ring block can form a concrete cylinder on the inner wall of the foundation pile hole, so that the foundation pile hole can not collapse easily in the downward moving process of the drill bit body is achieved.

Description

technical field [0001] The present application relates to the technical field of equipment related to foundation reinforcement and deviation correction, and in particular to a device for strengthening and deviation correction of a grouted composite foundation. Background technique [0002] After the construction of the building is completed, due to the uneven settlement of the foundation, the building is prone to inclination. For this reason, the building needs to be corrected. There are three main methods for correcting the deviation. One is to correct the low point of the building Jacking up, this correction method is to change the bottom foundation structure of the building, the second is to excavate the foundation at the high point side of the building, so that the high point side of the building sinks to achieve balance Effect. The newer technology generally treats both sides of the building separately by combining the above two methods at the same time to form a new p...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that in the existing drilling process for forming foundation pile holes, due to the loose soil or the requirement of a relatively large depth for the foundation pile holes, there is a defect that the foundation pile holes are prone to collapse
