Abstract

The invention relates to the field of static tests, and aims to solve the problems that an existing counterforce device is complicated in structure, large in transportation and construction difficulty, high in cost, and low in construction safety. The invention provides a combined type support beam counterforce loading device which comprises a target stress pressure-bearing beam and multiple pushing structures. The target stress pressure-bearing beam is in downwards press fit onto a target test pile through a vertical jacking force device; the jacking force device upwards supports the target stress pressure-bearing beam at the position between two ends of the target stress pressure-bearing beam; the multiple pushing structures are arranged in an anchoring manner; part of pushing structuresdownwards correspond to one end of the target stress pressure-bearing beam and can prevent the end of the target stress pressure-bearing beam from moving upwards; and the other part of pushing structures downwards correspond to the other end of the target stress pressure-bearing beam and can prevent the end of the target stress pressure-bearing beam from moving upwards. The combined type supportbeam counterforce loading device provided by the invention has the beneficial effects of low difficulty and cost in transportation and construction, and high construction safety.

Description

technical field [0001] The invention relates to the field of static load tests, in particular to a combined support beam reaction force loading device. Background technique [0002] The existing pile foundation test methods are based on the test load and the layout of the test site, usually using the surcharge method, the reverse anchor pile method, or both methods at the same time. Among them, the large-tonnage and large-load anchor pile method has more and more requirements for the site. Due to the limitations of transportation and on-site construction conditions, the following problems exist in the large-load test of the anti-anchor method or the traditional method: [0003] When the steel structure pressure beam is used, the structure is complex and heavy, and the on-site installation is inconvenient, resulting in high on-site construction costs and corresponding high transportation costs; [0004] The strength requirements of the main structural beams are increased, an...
