Description

Technical Field

[0001] The utility model relates to the technical field of sediment thickness detection, in particular to a sediment thickness detection instrument for bored cast-in-place piles. Background Art

[0002] The sediment of bored piles refers to the sediment that is precipitated or left behind by the collapsed hole during the drilling and grouting process and is not carried away by the circulating mud. If the sediment is too thick, on the one hand, it will cause the concrete that falls by gravity to flip part of the sediment up. In the process of the sediment flipping up, a small amount of sediment will be mixed into the fresh concrete, causing the concrete to be impure and seriously affecting the strength of the concrete; on the other hand, in addition to the sediment that flips up, there is a small amount of sediment that has not been turned up and continues to stay at the bottom of the hole, forming a sandwich between the bottom of the hole and the bottom of the pile; on the other hand, due to the small specific gravity of the sediment at the bottom of the pile, it cannot play the effect of embedding the bottom of the pile, and the effectiveness of the pile bottom in resisting bending moment is reduced, resulting in potential large deformation, which is not good for the stress and stability of the pile body. It can be seen that the thickness of the sediment is a relatively important indicator in the construction process, but there is no device in the prior art that can quickly measure the thickness of the sediment.

[0003] Therefore, it is necessary to provide a new bored pile sediment thickness detection instrument to solve the above technical problems. Utility Model Content

[0006] Preferably, the lifting and holding mechanism includes a plurality of slots provided on both sides of the steel chisel and a hinged seat fixedly mounted on the top of the disc, a rotating shaft is rotatably mounted on the hinged seat, a clamping rod is provided on the outer fixed sleeve of the rotating shaft, and a clamping block is provided on the side where the two clamping rods are close to each other, and the clamping block is located in the corresponding slot.

[0010] Compared with the related art, the bored pile sediment thickness detection instrument provided by the utility model has the following beneficial effects:

[0011] The utility model provides a sediment thickness detection instrument for bored cast-in-place piles. The circular disc is arranged so that the circular disc will not sink into the sediment, thereby preventing the sediment from splashing onto the steel chisel above the circular disc when the steel chisel is inserted into the sediment to measure the thickness of the sediment, thereby ensuring the accuracy of the measurement. The lifting and clamping mechanism composed of a clamping groove, a clamping rod, a clamping block, an articulated seat, a rotating shaft and a torsion spring can prevent the clamping rod, the clamping block, the articulated seat, the rotating shaft and the torsion spring from being immersed in the sediment without hindering the steel chisel from being inserted into the sediment, thereby ensuring the normal use of the lifting and clamping mechanism.
