Pressure test device and method for prestressed pipe pile through peripheral pipe pile in component force measuring mode

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a pressure test method for a prestressed pipe pile and a device used in the method. The device comprises one set of center clamping plates and at least two sets of component force clamping plates. Each center clamping plate comprises a center upper clamping plate body and a center lower clamping plate body, wherein the center upper clamping plate body and the center lower clamping plate body are respectively provided with at least two sets of screw through holes corresponding to one another in position. Each component force clamping plate comprises an upper component force clamping plate body and a lower component force clamping plate body, wherein the upper component force clamping plate body and the lower component force clamping plate body are respectively provided with at least two sets of screw through holes corresponding to one another in position. The center clamping plates and the component force clamping plates are connected through steel beams. The method and device have the advantages that a prestressed pipe pile around the tested prestressed pipe pile serves as a ground anchor, a high frame does not need to be erected, heavy objects for pressing are not needed, the bearing force at which the prestressed pipe pile cannot sink can be measured only through a layer of radioactive support pressure test device, the cost of using hundreds of or thousands of tons of heavy articles to carry out the pressure test is greatly saved, the accident risk that the heavy articles collapse is completely avoided, the time for measuring test pressure is greatly shortened, and construction time is saved.

Description

technical field [0001] The invention belongs to the technical field of pile foundation detection of buildings, in particular to a pressure test method for prestressed pipe piles and a used device. Background technique [0002] The current pressure test method for prestressed pipe piles is to pile up the weight required for pressure test with concrete weights on the top of the prestressed pipe piles. Pressure test the prestressed pipe pile with tons of weight to determine the pressure resistance capacity of the prestressed pipe pile. This method needs to build a very wide load-bearing frame. When the weight is too heavy and slightly unbalanced, the load-bearing frame is also easy to collapse and cause an accident. Contents of the invention [0003] The purpose of the present invention is to provide and utilize the prestressed pipe piles or other piles around the prestressed pipe piles to be tested as ground anchors, without building an elevated frame, without pressing heav...
