Device for detecting length and pile splicing quality of pre-stress concrete hollow pile and method of device

Abstract

The invention discloses a device for detecting length and pile splicing quality of pre-stress concrete hollow pile and a method of the device. The device for detecting length and pile splicing qualityof pre-stress concrete hollow pile comprises a detection instrument located on the ground, a cable winch and a hollow pile, wherein the detection instrument is electrically connected with the cable winch through a cable; the detector further comprises a counter, a guiding fixing cover and a pile inside sensor, wherein the counter is electrically connected with the detection instrument and is fixed on the guiding fixing cover, the guiding fixing cover is arranged at the top of the hollow pile, and the pile inside sensor is electrically connected with the detection instrument through the cable.According to the structure of the detector of pre-stress concrete hollow pile length and pile splicing quality, a measuring arm inclination angle and a roller rotation speed detected by the bottom orinner part of the hollow pile are transmitted to the detection instrument through the pile inside sensor, and the pulling speed of the cable in the detection instrument transmitted by the counter iscombined, so that the position of the bottom end of the pile is judged, the pile length is thus calculated, and the pile splicing quality is analyzed; and the overall structure is simple, the operation is easy, the measuring efficiency is comparatively high, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a device and method for detecting the length and quality of prestressed concrete hollow piles. Background technique [0002] With the vigorous development of engineering construction in our country, the proportion of prestressed concrete hollow pile foundation in the foundation form is getting higher and higher. The prestressed concrete hollow pile is a hollow slender concrete prefabricated component, mainly composed of concrete, steel bars, and end plates. The bearing layer at the pile end is generally clay, sand, and silt. It has the advantages of fast speed, good driving resistance and high pile quality, and is widely used in soft soil geological conditions. The bearing capacity of prestressed concrete hollow piles is composed of pile side friction resistance and pile tip resistance, and the construction pile length is very important for pile side friction re...
