Problems solved by technology

However, for foundation pits with large depths, high water levels, and narrow sites, on the one hand, the construction of anti-floating piles and anchor rods is difficult and the construction period is long, and there are certain quality and safety risks.
On the other hand, the cost of the foundation pit support system and anti-floating measures is relatively high, and the foundation pit support is a temporary structure that only plays a role within the service life of the foundation pit support, and there is a certain degree of "waste of resources" Phenomenon, not environmentally friendly, not economical

Embodiment Construction

[0025] A kind of support system provided by the present invention and the method for substituting the anti-floating measures of main body structure permanent combination, this method specifically comprises the following steps:

[0026] 1) The support system is connected with the main structure structure; the support system is support piles, and the steel bars reserved on the crown beams of the support piles are anchored with the steel bars of the main structure;

[0027] If the steel bars reserved for the crown beam do not meet the design requirements, it may be considered to plant reinforcements on the support piles. One end of the planting reinforcement meets the implantation depth, and the other end meets the anchoring requirements of the main structure;

[0028] The side formwork of the supporting pile crown beam is drilled on site according to the reserved steel bar position of the main structure to meet the flexibility and convenience of on-site construction; the crown be...

Abstract

The invention relates to a method for replacing an anti-floating measure through permanent and temporary combination of a supporting system and a main body structure. The method comprises the following steps that (1) the supporting system is connected with the main body structure; (2) a main body structure raft plate is externally expanded to a supporting system, and backfilling is carried out to increase the balance weight; the design method that anti-floating piles are additionally arranged on a raft plate is replaced by means that a supporting system and a main body structure outer wall are subjected to structural connection, and expanded feet are externally arranged on the structure raft plate to increase counterweights; according to the external expansion part, the structural balance weight is increased in a soil covering or concrete pouring mode, and therefore the purpose that a supporting system and a main body structure are permanently and temporarily combined to resist floating synergistically is achieved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering design and construction, and specifically relates to a method for permanently combining a support system with a main structure to replace anti-floating measures. Background technique [0002] With the development of urban construction in our country, there are more and more projects featuring high groundwater level, large excavation depth, and small usable range around them. When engineering designers face the geological environment of deep foundation pits and high water levels, they must first solve the problem of anti-floating of the main structure. However, measures such as setting anti-floating piles and anchor rods under the main structure or increasing the self-weight of the main structure have become one of the few options. However, for foundation pits with large depths, high water levels, and narrow sites, on the one hand, the construction of anti-floating piles and anchor rods ...
