Portable foundation pile post-grouting device and stirring, grouting and cleaning method thereof

Abstract

The invention relates to a portable foundation pile post-grouting device and a stirring, grouting and cleaning method thereof. The portable foundation pile post-grouting device and the stirring, grouting and cleaning method thereof are applied to a building foundation pile self-balancing bearing capacity static load detection test post-grouting treatment process. The portable foundation pile post-grouting device comprises a stirring and weighing device, a gas-liquid booster pump, an automatic feeding device, a grouting device body and cleaning devices, the stirring and weighing device is arranged on the upper layer of the post-grouting device, the plurality of cleaning devices are arranged on the inner edge of the side wall of the stirring and weighing device, the automatic feeding deviceis located on one side of the stirring and weighing device, the grouting device body is arranged on the lower layer of the post-grouting device, a stirring part of the grouting device body is providedwith an automatic weighing device and a pressure gauge, and the gas-liquid booster pump is connected with the grouting device body. According to the portable foundation pile post-grouting device andthe stirring, grouting and cleaning method thereof, inner grouting and outer grouting of a load box cylinder can be guaranteed to be carried out smoothly, continuous grout discharging is realized, grout is uniformly mixed, the strength and the integrity of a pile body of a pile foundation are further guaranteed, meanwhile, the portable foundation pile post-grouting device is small in power and lowin energy consumption, compressed oil is not adopted, and the requirements of energy conservation and environmental protection are met.

Description

technical field [0001] The invention relates to a portable foundation pile post-grouting device and a stirring and grouting cleaning method thereof, which are applied in the post-grouting treatment process of the self-balancing bearing capacity static load detection test of building foundation piles, in particular to a self-balancing bearing capacity of foundation piles The utility model relates to a portable device and method for grouting inside and outside a load box cylinder after a static load detection test. Background technique [0002] The high-pressure grouting pumps currently in use basically use high-power motors to drive high-pressure grouting. Since the high-pressure grouting method is used, the motor power is required to be high, which makes the equipment relatively cumbersome, and the weight is basically above 400KG. It is convenient for transportation and on-site use; its drive adopts a high-power motor, which consumes a lot of energy, and the grouting materia...

Problems solved by technology

[0003] The purpose of the present invention is to provide a portable post-pile grouting device and its stirring and grouting cleaning method. The device is light in weight, complete in function, novel in structure, high in automation, easy to transport and carry, and uses compressed air as a power source during operation. It is used for grouting inside and outside the load box cylinder for self-balancing static load detection of foundation piles to solve the problem of broken piles for self-balance detection of foundation piles. Using this device can ensure smooth grouting inside and outside the load box cylinder and realize continuous grouting. The slurry is evenly mixed, which further ensures the strength and integrity of the pile body. At the same time, the device has low power, low energy consumption, and does not use compressed oil, which meets the requirements of energy saving and environmental protection.
