Abstract
Description
Technical Field

[0002] Grouting test refers to a test to select an appropriate location in the proposed area to conduct cemented rock and soil in order to understand the possibility of grouting treatment of rock and soil and obtain relevant technical and economic indicators. In the grouting test, the quality of the hole directly affects the quality of the pile after concrete pouring. If the hole diameter of the pile hole is too small, the bearing capacity of the pile tip will be reduced, and the bearing capacity of the whole pile will be reduced; the expansion of the upper part of the pile hole will lead to an increase in the upper side resistance of the pile, and at the same time, the concrete pouring volume of a single pile will increase, thereby increasing the construction cost of the bored pile. Therefore, after the drilling of the grouting hole is completed, the hole diameter and verticality of the hole need to be tested using a borehole inspection device.
[0003] The borehole detector currently used mainly includes a column and conical ends arranged at both ends of the column. The column and the two conical ends form a cage-like structure. The outer diameter of the borehole detector is adapted to the aperture of the grouting hole, and the length is 4-6 times the outer diameter.
[0004] The column and the conical end of the existing borehole detector are welded by steel bars and cannot be disassembled or adjusted in telescopic manner, which causes the borehole detector to occupy a lot of transportation space and needs to be improved. Utility Model Content
