Vehicular integral type shell structure ballasting body pile-loading method

Abstract

The invention relates to a vehicular integral type shell structure ballasting body pile-loading method. The vehicular integral type shell structure ballasting body pile-loading method is characterized by comprising the following steps that a, the plane position of a static load test point is determined, the static load test point is used as the center to process a static load foundation; and a steel structural buttress is installed; b, a shell pile-loading body bottom structure is installed, so that a vehicular main beam platform center and the test point are in center coincidence, and a vehicular main beam platform and an integral type steel structural platform jointly form a bottom structure of a shell pile-loading body; c, side plates are installed on the outer edges of the bottom structure; d, a building waterproof layer is built or seepage-proofing water proof materials are installed; e, vertical and horizontal steel plates/sectional materials or steel structural plates are installed; f, a steel structural scissor support and a waist beam are installed; g, the shell pile-loading body is filled until the requirement for the oil-loading capacity is met; h, detection equipment is installed for detecting; i, ballasts are removed, and the shell pile-loading body is moved to a next point; j, the above processes are repeated until the whole static load test project is completed; and k, the shell pile-loading body is removed.

Description

technical field [0001] The invention relates to a ballast stacking method and device used in vertical anti-compressive static load test ballast counterforce when testing the bearing capacity of civil engineering foundations, in particular to a ballast pile with a vehicle-mounted integral shell structure upload method. 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. The artificial ground compaction and surcharge is basically not affected by the site conditions and the ratio of the frictional resistance of the pile itself and the end bearing force. It is widely used in the vertical compressive static load test. The follow...

Problems solved by technology

4. If the piled objects below are soil, gravel, rocks or water tanks (bags), etc., when piled high, the piled objects will move laterally, and the danger will increase.

The existing water tank is a whole, the weight is not heavy but the volume is large during transportation, and the transportation workload is also large. In order to reduce the transportation workload, sometimes it is made into water tanks of different sizes, and they are packaged during transportation, but the specifications of the water tanks are different. It is also inconvenient to stack and overlap

[0006] Static load tests of large, medium and small tonnages can be carried out by stacking tank columns, but there are also problems of large field transportation and high manufacturing costs during transportation, just like water tanks

[0007] Therefore, there are technical gaps in the method of stacking load and stacking carrier used in the vertical compressive static load test when the existing civil engineering foundation piles are tested.
