Problems solved by technology

[0003] Now the water tank is filled with water as the heavy object used for the pressure test foundation pipe pile. The disadvantage is that if the water tank is small in size, if the load-bearing frame on the foundation pile is tilted, the water in the water tank pressed on the load-bearing frame It will lean towards the lower side, and a large number of water tanks on the load-bearing frame will all tilt in one direction, and the entire load-bearing frame will topple over, causing an accident.
If the volume of the water tank is large, the bottom water tank cannot withstand the upward force of the hydraulic pump for pressure test placed on the foundation pipe pile, and the bottom water tank will be damaged.

Abstract

The invention discloses counterweight combined water tanks for the pressure test of foundation tubular piles and a pressure test method, and belongs to the technical field of pile foundation detection of a building. The combined water tanks include the four bottom-layer water tanks which are arranged on the foundation tubular piles in a Chinese character 'qi' shape and the four upper-layer water tanks which are overlapped on the four bottom-layer water tanks in a Chinese character 'chuan' shape. The pressure test method includes the steps that (1) a pressure test and load bearing combined device is built; (2) a supporting strip-shaped stack for stable arrangement of the water tanks is formed; (3) the four bottom-layer water tanks arranged in the Chinese character 'qi' shape are arranged; (4) water is injected into the four bottom-layer water tanks to increase the weight; (5) the four upper-layer water tanks arranged in the Chinese character 'chuan' shape are arranged on the four bottom-layer water tanks; and (6) a pressure test instrument is started to detect the descending height of the foundation tubular piles under test. The counterweight combined water tanks for the pressure test of the foundation tubular piles and the pressure test method have the advantages that the conveying quantity of counterweight objects is reduced by eight times, the conveying efficiency is improved, the conveying expenses are reduced, the bottom-layer water tanks are prevented from inclining or toppling over in the direction away from the foundation tubular piles, and the purpose that the water tanks can be filled with water to serve as a counterweight and provide pressure for the foundation tubular piles is achieved.

Description

technical field [0001] The invention belongs to the technical field of pile foundation detection of buildings, in particular to a counterweight device and a pressure test detection method for the pressure test of foundation pipe piles. Background technique [0002] The current pressure test method for foundation pipe piles is to pile up the weight required for pressure testing with concrete weights on the foundation pipe piles, often hundreds of tons or thousands of tons are stacked on a foundation pipe pile Ton weight is used to test the pressure of the foundation pipe piles to determine the pressure resistance of the foundation pipe piles. This method needs hundreds of tons of thousands of tons of cement blocks as heavy objects, and these hundreds of tons of thousands of tons of cement blocks are transported from a construction site to other construction sites as heavy objects to consume a large amount of manpower and expense. [0003] Now the water tank is filled with wa...
