Engineering building pile construction method

Abstract

The invention relates to the technical field of underground structure engineering, and discloses an engineering building pile construction method. The problems that as for an underground structure engineering foundation slab on the current market and a construction and use method of the underground structure engineering foundation slab, the pressure bearing effect is poor, the slab is prone to local cracking, the service life and stability of the slab are affected, and the periphery of the slab lacks protective measures, the condition of edge collapse is prone to occurring, normal use of the whole slab is affected, laid objects at the bottom of the slab are different in horizontal height, and the slab is uneven in pressuring bearing capacity and consequently prone to damage are solved. A manual hole digging pile is included, a lime layer is laid at one end of the manual hole digging pile, and a waterproof layer is laid and mounted on the lime layer. The engineering building pile construction method has the advantages that the pressure bearing effect is good, local cracking caused by the large pressure is avoided, the service life is long, stability is good, the periphery of the slab can be protected well, edge collapse is not prone to being generated, the slab is used stably, the laid objects are the same in horizontal height, and the slab is even in pressure bearing and not prone to damage.

Description

technical field [0001] The invention belongs to the technical field of underground building construction, and specifically relates to an underground engineering foundation floor structure and a construction and use 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 function 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...

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 and use method, which effectively solves the poor pressure bearing effect of the underground structure engineering foundation floor and its construction and use method on the market. , the base plate is prone to local cracking, which affects the service life and stability of the base plate. The lack of protective measures around the base plate is prone to edge collapse, which affects the normal use of the entire base plate. The level of the bottom of the base plate is different, and the base plate is under pressure The problem of uneven capacity and easy damage
