Device and construction method for dredging pipe blocked by final setting cement paste for sounding pipe cast-in-place pile

Abstract

The invention discloses a device for dredging a pipe blocked by final setting cement paste for a sounding pipe cast-in-place pile and a construction method, and the device comprises a fixed plate, a fixed frame and a rotating assembly. A working motor is arranged at the top of the outer wall of the fixed plate, the fixed frame is fixedly arranged at the bottom of the fixed plate, two sliding frames are fixedly arranged on the inner wall of the fixed frame, the rotating assembly is fixedly arranged in the fixed frame, movably arranged at the bottom of the fixed plate and used for transforming rotation into telescopic pushing. A movable column body is connected with a sliding rod, a buffering assembly and an auxiliary spring, cement smashing operation can be rapidly conducted on a blocked area, a blocked pipeline is unblocked, the speed is high, the stability is high, the vibration effect generated by the dredging device is reduced, the stability of the dredging device is improved, the dredging device can be installed on the pipeline, the vibration crushing effect can be automatically achieved only by fixing the dredging device, the vibration part can be prolonged after cleaning, and finally set cement in the deep position can be crushed.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a device and a construction method for dredging a pipe blocked by final setting cement slurry with an acoustic measuring pipe pouring pile. Background technique [0002] At present, the grouting pipe is a pre-embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe seepage joints, gaps between ground walls, etc. in concrete, between the joints of new and old concrete It is very suitable to install grouting pipes between them. When water seeps into the joints, it can be blocked by injecting grout through the PVC port set on the surface. This method can seal the joints. The appropriate grouting time can be selected at the end of concrete curing. After grouting, leaking joints can also be permanently sealed by this method. During the grouting process, it is necessary to prevent the backflow of the grout to avoid damage to the grou...

AI Technical Summary

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. Aspect 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 final setting state
