Description

Hole pile verticality detection device

Technical Field

The utility model belongs to the technical field of the architectural survey technique and specifically relates to a hole stake straightness detection device that hangs down.

Background

At present, with the rapid development of the domestic building field, the cast-in-situ bored pile is widely applied to various fields such as bridges, subways and house buildings, the cast-in-situ bored pile is generally used as a foundation pile, and after the foundation pile is drilled, the perpendicularity of the foundation pile needs to be detected so as to ensure the stability of later buildings. At present, the following main detection aspects for the perpendicularity of a foundation pile are provided:

firstly, detecting by adopting a verticality numerical control device carried by the drilling machine. However, the verticality numerical control device carried by the pile drilling machine affects the precision of the numerical control device according to objective factors such as the service time limit and the abrasion degree of the machine, so that the verticality cannot be detected by the device singly.

And secondly, manufacturing a cage exploring device, wherein the diameter of the cage exploring device is smaller than that of the pile foundation by about 10 cm-15 cm, and the cage exploring device is vertically transferred by a crane, if the pile foundation verticality does not reach the standard, the cage exploring device cannot be freely transferred, so that whether the verticality of the pile foundation is qualified is judged. However, the cage detector is adopted, a crane is required to be matched every time, the cost is high, the efficiency is not high, the cage detector is heavy, the cage detector is not easy to sense after slightly touching the wall, and therefore the verticality precision is rough.

And thirdly, detecting the verticality in the hole by adopting a plumb bob, placing the plumb bob after the upper opening of the plumb bob is away from the hole wall by a certain distance, measuring the distance between the plumb bob and the hole wall after the plumb bob collides with the wall, and subtracting the radius of the plumb bob and the verticality deviation value of the pile by using the numerical value. However, the plumb degree is measured by adopting the plumb bob, and because the depth of the bored pile hole is deep, the plumb bob is a cone, and the distance between the off-hole plumb bob and the hole wall is not easy to measure accurately, so that the error is large.

And fourthly, measuring the verticality by adopting a horizontal ruler, wherein the method is suitable for detecting the verticality during full casing follow-up construction, and the horizontal ruler is adopted to detect the verticality of the casing in the casing running process. However, when the full casing is adopted for follow-up, the verticality of the casing is measured by using a horizontal ruler, the length of the horizontal ruler is about two meters generally, the hole depth is more than ten meters or deeper, certain limitation is realized, and the measurement error is larger.
