The invention relates to a foundation pile self-reaction force balance test integrated device and belongs to the technical field of building equipment. An upper connection board and a lower connection board of the device are connected with a hydraulic cylinder through bolts. A plurality of telescopic protection pipes are arranged around a slurry guide pipe. The two ends of each telescopic protection pipe are sealed. An upper threaded reinforcing steel bar and a lower threaded reinforcing steel bar which are in overlap joint are arranged inside each telescopic protection pipe and are connected with an upper corresponding reinforcing steel bar cage main bar and a lower corresponding reinforcing steel bar cage main bar respectively. Displacement rods and displacement protection pipes which are arranged outside the displacement rods in a sleeving mode are arranged on the two sides of the device. A pressurized water pipe connected with the hydraulic cylinder is led to the ground, a grouting pipe connected with the hydraulic cylinder is led to the ground, an ultra-high pressure water station is connected with the pressurized water pipe, and a mortar pressurization station is connected with the grouting pipe. According to the device, the problem of pollution of residual hydraulic oil to the environment after an existing foundation pile self-reaction force balance test is effectively solved, and horizontal shear resistance of tested foundation piles is increased.
Description
technical field [0001] The invention relates to an integrated device for foundation pile self-reflection force balance test, which belongs to the technical field of construction equipment. Background technique [0002] With the rapid development of national construction, large and super large buildings and bridge projects have increased dramatically, and the design of single pile bearing capacity of pile foundation is also increasing, and the characteristic value of many single pile bearing capacity is more than 10,000 tons. The traditional surcharge method and anchor pile method cannot meet the testing requirements of super-large-tonnage foundation pile bearing capacity, while the current self-reflexive force balance method uses a high-pressure oil pump to load the load of the foundation pile self-reflective force balance test device. Therefore, there are environmental pollution problems of the remaining hydraulic oil after the test, and the problem that the concrete and th...
