Prefabricated hollow pipe pile verticality measuring device and measuring method thereof

Abstract

The invention relates to the technical field of construction tools, in particular to a prefabricated hollow pipe pile verticality measuring device, which comprises a measuring pipe of an inclinometerand a plurality of centralizers mounted on the measuring pipe in a sleeved manner, wherein the centralizers comprise clamps, movable hoops and a plurality of arc-shaped spring sheets; the clamps are fixed on the measuring pipe; the movable hoops are sleeved on the measuring pipe; and the spring sheets are connected between the clamps and the movable hoops to form an annular shape. The device is developed aiming at the problem that the inclination of the hollow pipe pile cannot be measured in the prior art. By using the prior inclination measuring instrument, the centralizers are sleeved on themeasuring pipe of the measuring instrument, and the centralizers can always ensure that the measuring pipe is positioned in the center of the hollow pipe pile, and thus the measuring accuracy of themeasuring instrument is greatly ensured, and the problem that the inclination of the hollow pipe pile cannot be measured at present is effectively solved.

Description

technical field [0001] The invention relates to the technical field of construction tools, in particular to a prefabricated hollow pipe pile verticality measuring device and a measuring method thereof. Background technique [0002] With the development of construction technology, the field of pile foundation construction is changing with each passing day. Prestressed high-strength concrete pipe piles have many advantages such as fast construction speed, low price, high bearing capacity, stable quality, short maintenance time, convenient construction and pollution-free construction. In recent years, it has been widely used in foundation projects in various places, especially municipal soft soil foundations and collapsible foundations. At present, in addition to ordinary concrete pipe piles in China, hollow pipe piles have appeared in order to save costs. Hollow pipe piles are divided into many pipe joints to go deep into the ground, such as figure 1 As shown, there are sold...

AI Technical Summary

Problems solved by technology

At present, in addition to ordinary concrete pipe piles in China, hollow pipe piles have appeared in order to save costs. Hollow pipe piles are divided into many pipe joints to go deep into the ground, such as figure 1 As shown, there are solder joints 6 between the pipe joints, and there will often be a certain inclination between two adjacent pipe joints. At present, the state stipulates that the inclination of the hollow pipe pile cannot exceed ±1%. There is no suitable method and device for measuring how many degrees
