Abstract

The invention discloses a non-brace support device which comprises support piles, anchor cables, support pillars and unbonded anchor cables. The invention provides a construction method of the non-brace support device. According to the device, by utilizing the functions of the anchor cables and the support pillars, the acting forces stressed on the support piles are transmitted into a soil body. According to the non-brace support device and the construction method thereof provided by the invention, the sufficient horizontal forces are provided through the unbonded anchor cables, and the horizontal pulling forces stressed on the unbonded anchor cables are transmitted to the bedrock positions on the pile bottoms through the support pillars. By adopting the vertically arranged anchor cables and the horizontally arranged unbonded anchor cables, the occurrence of the phenomenon that an existing anchor cable is slantways inserted into the soil body and occupies a large area so as to be limited by the neighboring building foundation is avoided, and the occupied area is reduced, so that the non-brace support device not only meets the engineering needs but also can be applicable to the places with the limited area. On the premise of ensuring the safety, the use of the anchor cables is reduced, the cost is saved, and the non-brace support device has the beneficial effects of simple structure, less occupied range, and low construction cost.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to a support device and a construction method thereof, in particular to a support-free support device and a construction method thereof. Background technique [0002] Pile anchor is a relatively new support technology in our country. Compared with the traditional support, the anchor cable has better performance in terms of bearing capacity, support for large-span sections and support for roof fall areas. And in terms of applicability, pile-anchor support is widely applicable and can be applied in complex soil layers. All in all, pile-anchor support has many advantages. Although the existing pile-anchor support adopts the connection structure of anchor rod and anchor cable, in the current practical engineering application, the anchor cable in the support usually cannot be recovered, resulting in high economic cost of the pile-anchor support structure, and in In the design proce...
