Foundation treatment method under dynamic load and static load mixing effect of equipment room

Abstract

The invention relates to a foundation treatment method under the dynamic load and static load mixing effect of an equipment room, and relates to the technical field of building engineering construction. The method comprises the following steps that (1), manual hole digging piles are constructed on a dynamic load area, and a reinforced concrete bearing platform used for supporting dynamic load generation equipment is constructed after a gravel cushion layer is laid in the top area of the manual hole digging piles; (2), high-pressure jet grouting piles are constructed in a static load area, and a reinforced concrete terrace used for supporting static load generation equipment is constructed after a gravel cushion layer is laid in the top area of the high-pressure jet grouting piles; (3), dividing joints are cut at the connection positions of the reinforced concrete bearing platform and the reinforced concrete terrace and are filled with sealing factice. By means of the foundation treatment method, the manual hole digging piles are adopted for supporting the reinforced concrete bearing platform in the dynamic load area for foundation treatment, and the high-pressure jet grouting piles are adopted for supporting the reinforced concrete terrace in the static load area for foundation treatment, so that the problems that the reinforced concrete terrace is locally sunken, cracks and the like when the equipment room is used later are avoided.

Description

technical field [0001] The invention belongs to the field of building engineering construction, and in particular relates to a foundation treatment method under the mixed action of dynamic load and static load in an equipment room. Background technique [0002] Considering the functional requirements of the building, the equipment room of some buildings often places equipment that generates large dynamic loads and equipment that only generates static loads at the same time. If the equipment room is designed above the first floor structure, it only needs to be considered separately in the design of the floor structure. relevant loads. If the equipment room is designed on the first floor, and the lower foundation is backfilled with plain soil, the conventional foundation treatment method is to construct a reinforced concrete floor after backfilling and compacting the plain soil layer by layer. It is difficult to guarantee the degree of safety, and the operation of dynamic loa...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the existing problems and defects in the prior art, and to provide a ground treatment method under the mixed action of dynamic load and static load in the equipment room, which adopts different foundations in the dynamic load area and the static load area in the equipment room. The treatment method solves the problems of local subsidence and cracking of the reinforced concrete floor when the equipment room is used later
