Embodiment Construction

[0034] The construction method of the foundation pit floor proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0035] Combine below Figure 1 to Figure 6 Describe in detail the construction method of the foundation pit floor of an embodiment of the present invention:

[0036] Step 1: Divide the area to be excavated of the foundation pit into several adjacent blocks F1, F2, ..., Fn, wherein n is an integer greater than 2;

[0037] The size and shape of each block can be determined according to the actual construction environment of the foundation pit to be ex...

Abstract

The invention provides a construction method of a bottom plate of a foundation pit. A region to be excavated of the foundation pit is divided into a plurality of small blocks, the bottom plate is constructed after the blocks are excavated one by one, so that unloading amount of excavated soil bodies every time is reduced greatly, the probability of raising of the bottom of the foundation pit after unloading of the excavated soil bodies is greatly reduced, and safety of construction is improved. In addition, before construction of the blocks of the bottom plate, reinforcement cages, corresponding to the blocks, of the bottom plate have been prefabricated, site construction time of construction of the bottom plate is greatly shortened, on one hand, the probability of raising of the bottom of the foundation pit is reduced further, on the other hand, the construction efficiency of the bottom plate of the foundation pit is improved effectively, and the purposes of safety and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a foundation pit floor. Background technique [0002] In order to ensure the safety of foundation pit construction, the safety of the main underground structure and the surrounding environment, comprehensive design and monitoring are required for foundation pit support, precipitation, earthwork excavation, and foundation pit floor construction. In recent years, with the excavation of foundation pits getting deeper and larger, the construction of super-large deep foundation pits has become more and more difficult to control the environmental deformation process, and one-time excavation has a greater impact on the surrounding environment. Large, huge soil excavation and unloading during construction, the rebound of the soil at the bottom of the foundation pit will also have an unavoidable adverse effect on the surrounding strata. [0003] In...
