An underground engineering crack repair device

Abstract

The invention discloses an underground engineering crack repair device, which belongs to the technical field of building construction. The soft liquid storage bag of the crack repairing device is provided with a liquid inlet and outlet, and the liquid inlet and outlet are connected to the buffer tank through the first connecting pipe and the second connecting pipe. The first connecting pipe is provided with a first one-way valve, and the second connecting pipe A second one-way valve is provided on the top, a first flowmeter is provided on the first connecting pipe, and a second flowmeter is provided on the second connecting pipe; a limit device is also provided outside the soft liquid storage bag; the first flowmeter Both the second flowmeter and the second flowmeter are electrically connected to the controller, and the electromagnetic valve on the grouting device and the third flowmeter are also electrically connected to the controller, and the controller is also connected to a delay module. The crack repairing device of the present invention detects the internal volume of the crack in advance before grouting, and adjusts the grouting amount in time according to the detection results at each position of the crack, so as to avoid the trouble of secondary grouting caused by too little grouting amount or the Excessive amount of grouting causes waste of grouting amount.

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
