Pile foundation depth tester

Abstract

The invention discloses a pile foundation depth tester. The pile foundation depth tester comprises a hole and a guide pipe. The lower end of the guide pipe is located in the hole. By additionally arranging a testing rod, ropes, sliding blocks, first copper layers, U-shaped frameworks and other structures, the guide pipe is arranged at the position two meters above the hole bottom, an air bag is inflated, concrete is poured into the hole from the guide pipe, a motor is started, by means of engaging of a worm and a worm wheel, a rollers rolls the ropes, the two ropes pull the sliding blocks at the same time till GPS positioners are located on the face layer of the concrete, while the sliding blocks ascend along with the face layer of the concrete, an electric bell is electrified, a worker judges the ascending height of the concrete face layer through the ringing frequency of the electric bell, comparison with the GPS positioners can also be achieved, the depth of the poured concrete is tested for the second time, then the speed for pulling out the guide pipe is controlled, the pile breaking phenomenon is prevented, and the concrete is poured better.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a pile foundation depth measuring instrument. Background technique [0002] At present, the concrete pouring of the bridge pile foundation adopts conduit pouring. The specification requires that the conduit be embedded in the concrete for 2 to 6 meters. During the pouring process, the depth of the conduit is determined based on the experience of the construction personnel. If the conduit depth is too large, the conduit cannot be lifted. Excessive lifting of the conduit leads to broken piles on the concrete surface of the conduit. Therefore, how to determine the buried depth of the conduit during the concrete pouring of the pile foundation is of great significance for concrete pouring. Contents of the invention [0003] The object of the present invention is to provide a pile foundation depth measuring instrument to solve the problems raised in the above-mentioned background t...
