Embodiment

[0033] Embodiment: a kind of large-scale deep foundation pit supporting construction structure, such as Figure 1-4 As shown, it includes the road surface 1, the side slope 2, the side of the foundation pit 3, the upper soil nail wall 4 set on the surface of the side slope 2, the lower soil nail wall 5 set on the side of the foundation pit 3, the crown beam 6, and the concrete support column 7 1. Concrete piles 8, steel pipes 9, block nets 10 and steel wires 11 arranged on the road surface 1; the side 3 of the foundation pit is arranged below the side slope 2. For foundation pits with good foundation geology and soil quality and shallow depth, the side 3 of the foundation pit It can be set perpendicular to the ground. For deep foundation pits with poor foundation geological conditions or a depth exceeding 5m, the side 3 of the foundation pit can be set to form a certain angle with the ground. The specific angle can be determined according to the construction situation on site. ...

Abstract

The invention relates to the technical field of intelligent environmental protection engineering construction, and particularly relates to a large deep foundation pit supporting construction structureand a method thereof. The large deep foundation pit supporting construction structure comprises a pavement, a side slope, a foundation pit side face, an upper soil nailing wall arranged on the surface of the side slope, a lower soil nailing wall arranged on the side face of a foundation pit, a crown beam, concrete supporting columns, concrete piles arranged on the pavement, steel pipes, a blocking net and steel wires. The method further comprises the steps of building the concrete piles, building the upper soil nailing wall, building the crown beam and the concrete supporting columns, building a blocking facility and building the lower soil nailing wall. The large deep foundation pit supporting construction structure and the method thereof solve the technical problems that in the prior art, in the deep foundation pit construction process, supporting is not firm, and the occupied area of a protection net is large.

Description

technical field [0001] The invention relates to the technical field of intelligent environmental protection engineering construction, in particular to a large-scale deep foundation pit support construction structure and a method thereof. Background technique [0002] A deep foundation pit refers to a project where the excavation depth exceeds 5 meters (including 5 meters), or the basement has more than three floors (including three floors), or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. The deep foundation pit engineering mainly includes the design and construction of the foundation pit support system and earthwork excavation. The foundation pit support is mainly to prevent the side of the foundation pit from collapsing and to prevent the falling of vehicles and personnel on the top of the foundation pit. The construction of foundation pit support facilities in the prior ar...
