Multi-stride hole probe fixing frame for pile foundation detection and use method of fixing frame

Abstract

The invention discloses a multi-stride hole probe fixing frame for pile foundation detection and a use method of the fixing frame, the fixing frame comprises an adjusting device and a driving device,wherein the adjusting device comprises a fixing housing and an adjusting screw, a length-adjustable push rod is arranged in the fixing housing, and a nut in thread connection with the adjusting screwis connected with the push rod; the motor of the driving device is connected with the fixing housing and arranged on one side of the fixing house, two pulleys are attached to the top and the surfacesof the two ends of the tail of the device respectively and used for fixing the direction of a probe wire. A semicircular guide sleeve structure is attached to the top of the push rod, moves along withthe push rod and fits an ultrasonic probe. According to the multi-stride hole probe fixing frame for pile foundation detection and the use method of the fixing frame, the structure design is reasonable, an ultrasonic probe can reach the position of an opening of a sound detection pipe through the device directly on a marine file foundation construction platform, a construction worker holds the ultrasonic probe and lowers the ultrasonic probe into a steel protection tube for dangerous operation, at the same time, the time can be saved, the construction efficiency is improved, the manufacturingcost is low, and the popularization is easy.

Description

technical field [0001] The invention relates to the technical field of offshore pile foundation detection, in particular to a multi-quad probe fixing frame for offshore pile foundation detection and a use method thereof. Background technique [0002] With the rapid development of my country's infrastructure construction, many foundation projects such as high-rise buildings and bridges adopt the foundation form of cast-in-place piles. Since cast-in-situ piles require a large amount of concrete pouring, affected by various construction factors, quality accidents such as broken piles, interlayers, necking, and holes often occur. Therefore, it is necessary to determine the position of the defect and evaluate it accurately, which has become a core issue of pile foundation quality inspection. When using ultrasonic instruments for pile foundation detection, it is necessary to install acoustic tubes in advance. The acoustic tubes are as long as the pile body and distributed vertica...

Problems solved by technology

However, in the construction of pile foundations of offshore bridges, it is often necessary to build offshore platforms in advance. During the pile foundation inspection, since the top of the pile is a certain distance from the offshore platform, construction workers need to use an escalator to go down to the top of the pile foundation and put the ultrasonic probe into the acoustic tube. , this operation is extremely dangerous and poses a great threat to the safety of construction personnel, and the construction efficiency is low
