Abstract

The invention belongs to the technical field of underground engineering construction, and particularly relates to a foundation pit excavation method. According to the foundation pit excavation method,an open trench is excavated along a construction route by providing an excavator and a heading machine, then the heading machine is placed in the open trench, and a pretreated foundation pit is excavated by the heading machine. In the way, on the one hand, the excavator and the heading machine are excavated simultaneously, the excavation time can be saved, and the excavation efficiency is improved; on the other hand, when the excavator, a bulldozer and other equipment are used for excavating the foundation pit, the bulldozer needs to be reserved for the area where the bulldozer moves forwardand turns in the open ditch as well as muck treatment, thus a large excavation cross section is required, however, the heading machine is placed in the open ditch to excavate the pretreated foundationpit, only the area where the heading machine is lowered and taken out needs to be reserved, and thus the larger excavation cross section is not required to be produced during excavation; and the foundation pit for construction can be formed by collecting and transporting mucks produced during driving of the heading machine and treating the pretreated foundation pit.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to a foundation pit excavation method. Background technique [0002] In the open-cut construction of the traditional comprehensive pipe gallery, the foundation pit excavation, foundation pit support, foundation pit bottom treatment and pre-installation preparation are carried out first, and then the prefabricated multi-section integral cast-in-place pipe gallery is transported to the construction site. Cranes or truck cranes are often used for installation, and then the overall cast-in-place pipe gallery is adjusted by manual assembly, and then the installation of the pipe gallery and subsequent waterproof treatment are continued manually, and finally the muck is backfilled and compacted. [0003] In the traditional open-cut construction of comprehensive utility tunnels, excavators and bulldozers are used to excavate foundation pits, and then...
