Overall type steel-based platform static load test load piling method for civil engineering

Abstract

The invention relates to an overall type steel-based platform static load test load piling method for civil engineering. The overall type steel-based platform static load test load piling method for civil engineering is characterized in that the method is performed according to the following steps that, a steel-based platform is selected, a jack is installed at the center of test points, a main beam is installed on the steel-based platform, a jack cylinder body and the main beam are effectively connected, and the steel-based platform and the main beam are effectively connected; a reference beam is installed, and loads are piled; after the weight of the piled loads reaches a regulated weight and a test instrument meets the test requirement according to check, test loading can be performed;after a test ends, parts of the loads are unloaded; and the steel-based platform, the main beam and part of the loads are transferred to a next test point, the above steps are repeated till detectionof the test points of the whole program ends. By means of the load piling method, the large tonnage load piling potential safety hazards can be eliminated, the detection time and the detection cost are saved, a large tonnage static load experiment can be safely and conveniently implemented, integrity is good, self moving can be achieved, speed is high, cost is low, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to a vertical anti-compression static load test pressure heaping platform and its supporting pier used in the vertical anti-compression static load test pressure weight reaction force when the civil engineering static load test is detected, especially a civil engineering The stacking method is tested with the static load test of the integral steel base platform. Background technique [0002] At present, the pressure and reaction force of the vertical compressive static load test mainly comes from 1. anchor piles and anchor rods; However, due to site conditions, anchor piles or anchor rods cannot be constructed, and the use of self-balancing load boxes is also limited because the frictional resistance of the pile body is much smaller than the end bearing capacity. Artificial ground compaction and heaping are basically not affected by the site conditions and the ratio of the frictional resistance of the pile itself and the end bear...

Problems solved by technology

Its disadvantages are: each test point needs to build and dismantle the test platform, load and unload the ballast load, which takes time and effort to increase the detection cost, increase the detection auxiliary time, and prolong the project duration

[0008] Therefore, there are defects in the existing method of surfacing in the vertical compressive static load test, which needs to be improved.
