Problems solved by technology

However, the current detection is generally completed by injecting water on one side and collecting on the other side. This method is simple and convenient. Inserting into the hole for suction, because the collection pipe is prone to clogging and other problems during suction, and at the same time, the surrounding area of ​​the collection will also seep during the collection process, which leads to little water collected even if the grouting effect is not good. Thus affecting the detection accuracy and detection reliability

Abstract

The invention discloses a grouting effect detection device. A telescopic and swing driving mechanism is optimally arranged, so that when suction is detected, the telescopic and swing driving mechanismcan drive a conical detection pipe to move slightly in the axial direction and realize slight eccentric rotation at the same time, wherein the slight eccentric rotation is that the rotating central axis of the conical detection pipe is not coaxial with the central axis of the conical detection pipe, the reliability during suction can be effectively guaranteed, and a suction hole is prevented frombeing blocked; and due to the rotating arrangement, the suction of the surrounding water seepage condition can be effectively realized, and then the suction amount is guaranteed, so that the reliability of judging the grouting effect can be improved, and the detection reliability is effectively improved.

Description

technical field [0001] Specifically, the invention relates to a grouting effect detection device, which relates to the related fields of civil construction detection. Background technique [0002] After the grouting construction is completed, the flow rate and permeability coefficient of the foundation shall be measured by means of pressing water, water injection or pumping through drilling holes in the grouting body, and supplementary grouting shall be carried out for unqualified ones. The number of inspection holes is about 5 to 10% of the total number of grouting holes. The focus of hole layout is on areas with poor geological conditions and parts with poor or questionable grouting quality. The grouting effect detection equipment is to check the grouting effect. Collect and detect the device structure. Since the purpose of grouting is to block and fix the pores in the rock formation, when detecting the effect of grouting, the detection of the seepage around the grouting ...
