Device for replacing non-initial-set cement paste and construction method

Abstract

The invention discloses a device for replacing non-initial-set cement paste and a construction method, and relates to the technical field of cement pouring, the device comprises a base with a supporting plate arranged at the top, a clamping mechanism and a clamping mechanism arranged on the supporting plate and used for clamping a cleaned pipe, and the clamping mechanism comprises a mounting component, a power buffering component and two clamping plates; the two clamping plates are slidably connected to the two ends of the mounting component correspondingly. According to the device for replacing the non-initial-setting cement paste and the construction method, the sounding pipe can be fixed to the same position through the clamping mechanism, so that the sounding pipe is kept stable and is not prone to moving in the cleaning process, the situation that the sounding pipe is damaged due to movement and cannot be used is avoided, loss is reduced, and the working efficiency is improved. And the interior of the sounding pipe can be fully cleaned through the rotary cleaning mechanism, and when cement paste remains in the sounding pipe, cleaning can be conducted through a brush, so that interior cleaning is more perfect and tidy, and the situation that the next use is affected by the cement paste does not exist.

Description

technical field [0001] The invention belongs to the technical field of cement pouring, in particular to a device and a construction method for replacing uninitialized 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] Grouting pipe is a pre-embedded grouting pipe system used for permanent sealing of construction joints in concrete, cold joints, pipe seepage joints, gaps between ground walls, etc., between joints of new and old concrete It is very suitable to install a grouting pipe. When w...

[0004] According to the conventional method, the acoustic test tube is also used as the post-grouting tube, and the ultrasonic test is carried out first, and then the post-grouting is carried out. The time of the post-grouting process is postponed until after the ultrasonic test. According to the test regulations, the ultrasonic test should be carried out after the concrete strength of the pile reaches 90%. After the above, the strength of the pile body is high at this time, and it is easy to cause blockage of the post-grouting pipe. The delay of the post-grouting process will affect the improvement of the bearing capacity of the single pile, causing the test date of the static load test to be postponed, thereby affecting the construction period. Post-grouting is carried out first, and ultrasonic testing is performed after the grouting is completed. It is necessary to replace the cement slurry on the acoustic measuring tube immediately after the grouting is completed. Therefore, a device and construction method for replacing the uninitialized cement slurry are required.
