Abstract

The invention relates to an in-cylinder grouting device used after a self-balancing load box static load detection test and a grouting method thereof, and is applied to the technical field of in-cylinder grouting of a load box after the building foundation pile self-balancing bearing force static load test. The device comprises a stirring device, a filtering stirring device, a stirring driving device, a weighing device, a pressurizing driving device, a pressurizing grouting device and an in-cylinder grouting load box; the filtering stirring device is arranged below the stirring device, the lower end of the filtering stirring device is connected to the stirring driving device, and the weighing device is located below the stirring driving device; the filtering stirring device is connected tothe pressurizing grouting device through a suction port, and the pressurizing grouting device is connected with the pressurizing driving device; an output port of the pressurizing grouting device isconnected with the in-cylinder grouting load box through a grouting pipe; and the in-cylinder grouting load box is connected with the grouting pipe.

Description

technical field [0001] The invention relates to an in-cylinder grouting device and a grouting method after a static load detection test of a self-balancing load box, which is applied to the technical field of grouting in a load box after a static load detection test of a self-balancing bearing capacity of a building foundation pile. Background technique [0002] At present, after the load box is applied to the self-balancing static load test of the foundation pile, only the gap near the load box after the foundation pile inspection is grouted and filled. Since there is no mature technology of grouting in the load box in the domestic market, it is used in engineering applications. At present, the grouting treatment in the load box cylinder is not possible, and the gap in the load box cylinder is not filled, resulting in a reduction in the cross-sectional effective area of ​​the pile foundation, weakening the strength of the pile foundation, and failing to meet the same strengt...
