Underground engineering crack repairing device

Abstract

The invention discloses an underground engineering crack repairing device, and belongs to the technical field of building construction. The underground engineering crack repairing device is characterized in that a liquid inlet and outlet is formed in a soft liquid containing bag, the liquid inlet and outlet is connected with a buffer tank through a first connecting pipe and a second connecting pipe, a first one-way valve is arranged on the first connecting pipe, a second one-way valve is arranged on the second connecting pipe, a first flow meter is arranged on the first connecting pipe. a second flow meter is arranged on the second connecting pipe, a limiting device is further arranged outside the soft liquid containing bag, the first flow meter and the second flow meter are both electrically connected with a controller, an electromagnetic valve on a grouting device and a third flow meter are both electrically connected with the controller, and the controller is further connected witha time delay module. According to the crack repairing device, the internal volume of a crack is detected in advance before grouting, the grouting amount is adjusted in time according to the detectionresult of each position of the crack, and the problem that secondary grouting is needed and trouble is caused due to the fact that the grouting amount is too small or the grouting amount is wasted dueto the fact that the grouting amount is too large is solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an underground engineering crack repairing device. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, land resources are becoming increasingly scarce and expensive in engineering construction, making engineering projects have to develop in the direction of underground space, and a large number of underground projects have emerged as the times require , the waterproofing of the basement is very important, and the setting of various joints brings difficulties to the waterproofing of the basement. If the structural design of the basement is unreasonable, or the construction quality cannot be guaranteed, the concrete in the basement is prone to cracks, causing the basement to leak , affecting its normal use.

[0002] With the rapid development of social economy and the continuous improvement of people's living standards, land resources are becoming increasingly scarce and expensive in engineering construction, making engineering projects have to develop in the direction of underground space, and a large number of underground projects have emerged as the times require , the waterproofing of the basement is very important, and the setting of various joints brings difficulties to the waterproofing of the basement. If the structural design of the basement is unreasonable, or the construction quality cannot be guaranteed, the concrete in the basement is prone to cracks, causing the basement to leak , affecting its normal use

[0003] Therefore, it is necessary to timely and effectively repair the cracks generated in the basement. The filling method is one of the ways to repair cracks. Generally, the cracks are first enlarged, and then the surface of the cracks is brushed and cleaned. Finally, the plugging slurry is filled to seal the cracks. For repairing, the grouting method or grouting device of the prior art cannot predict the amount of grouting for the cracks in advance. Even the same crack at different positions has wide and narrow, deep and shallow, so the grouting required to fill the cracks The amount of grout is constantly changing, and the currently used crack filling devices cannot accurately control the amount of grout, which may easily lead to insufficient filling of the filler, requiring secondary replenishment or waste of grout due to excessive grout injection
