Underground engineering foundation slab structure and construction method thereof

Abstract

The invention relates to the technical field of underground structural engineering and discloses an underground engineering foundation slab structure and a construction method thereof. The undergroundengineering foundation slab structure and the construction method thereof solve the problems that an underground structural engineering foundation slab and a construction and use method thereof in the current market have poor pressure-bearing effect, the slab is easy to generate the condition of local cracking, the service life and the stability of the slab are influenced, the peripheral protection measures of the slab are lacked, the condition of edge collapse is easy to occur, the normal use of the whole slab is influenced, the horizontal heights of laying things at the bottom of the slab are different, the pressure-bearing capacity of the slab is uneven, and the slab is prone to damage. The underground engineering foundation slab structure comprises manual hole digging piles, a lime layer is paved at one end of each manual hole digging pile, and a waterproof layer is paved on the lime layer. The underground engineering foundation slab structure and the construction method thereof have the advantages of good pressure-bearing effect, no local cracking due to large pressure, long service life and good stability, the periphery of the slab is well protected, edge collapse is not prone to occurring, the slab is stably used, the horizontal heights of the laying things are the same, the pressure borne by the slab is uniform, and the slab is not prone to damage.

Description

technical field [0001] The invention belongs to the technical field of underground building construction, in particular to an underground engineering foundation floor structure and a construction method thereof. Background technique [0002] Underground structures are divided into arched structures, circular and rectangular tubular structures, frame structures, thin shell structures, and special-shaped structures according to their structural forms. The loads borne by underground structures are divided into the following three categories according to their functional characteristics and possible situations during use. : That is, permanent (main) loads, variable (additional) loads and occasional (special) loads. [0003] However, the base floor structure used in the underground engineering currently on the market is laid layer by layer by filling the upper and lower layers in sequence, which will lead to: when the foundation floor structure is used, the upper part of the foun...

AI Technical Summary

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an underground engineering foundation floor structure and its construction method, which effectively solves the problem of the poor pressure bearing effect of the underground structure engineering foundation floor and its construction and use method on the market. The floor is prone to local cracking, which affects the service life and stability of the floor. The lack of protective measures around the floor is prone to edge collapse, which affects the normal use of the entire floor. The level of the bottom of the floor is different, and the pressure capacity of the floor Uneven, easily damaged problems
