Device for dredging pipe blocked by initial setting cement paste and construction method

Abstract

The invention discloses a device for dredging a pipe blocked by initial setting cement paste and a construction method, and relates to the technical field of cement pouring, the device comprises a base provided with a supporting plate at the top, a clamping mechanism arranged on the supporting plate and used for clamping a cleaned pipe, and the clamping mechanism comprises an installation buffering part, two clamping plates and two anti-skid rubber mats. The sounding pipes needing to be cleaned can be fixed to the same position through the clamping mechanism, the sounding pipes are kept stable and not prone to generating relative movement in the process of being impacted and cleaning the interiors, damage to the interiors of the sounding pipes due to movement is avoided, cement solidified in the sounding pipes can be effectively impacted through the impact mechanism, and the cleaning efficiency is improved. The overall mechanism is simple and convenient to use, the flushing pipe flushes water from the top, the water pumping pipe is connected with the low-pressure pump and bound with the balance weight to extend to the dredging portion, the internal cleaning effect is achieved, and the cleaning difficulty of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of cement pouring, in particular to a device and a construction method for unblocking pipes blocked by initial setting cement slurry. Background technique [0002] The acoustic test tube is an indispensable acoustic wave detection tube, and the quality of a pile can be detected by using the acoustic test tube. An important part of the ultrasonic testing system, its pre-embedded method in the pile and its layout on the cross-section of the pile will directly affect the testing results. The quality of embedding and the thickness of the pipe wall should be strictly controlled during construction to ensure the smooth progress of the inspection work. [0003] In the construction of cast-in-situ piles with acoustic tubes and grouting tubes, post-grouting is performed first, and ultrasonic testing is performed after the grouting is completed, which can achieve the goal of shortening the construction period. In te...

Problems solved by technology

[0003] In the construction of cast-in-situ piles with acoustic tubes and grouting tubes, post-grouting is performed first, and ultrasonic testing is performed after the grouting is completed, which can achieve the goal of shortening the construction period. In terms of factors, the cement slurry in the acoustic measurement tube may not be replaced in time after the post-grouting is completed, and the cement slurry in the tube reaches the initial setting state, so a device for dredging the initial setting cement slurry plugging pipe is needed
