Embodiment Construction

[0018] The present invention is described in detail below in conjunction with accompanying drawing:

[0019] Such as figure 1 As shown, according to the actual situation of the deep foundation pit construction site, the central area that is convenient for mechanical excavation construction is divided into mechanical excavation area 1, and the area that is not convenient for mechanical excavation construction is divided into hydraulic scouring area 2. According to the foundation pit area and excavation depth, calculate the number of mechanical excavation equipment and arrange construction machinery. Under the condition that the number of mechanical excavation equipment is determined, by calculating the workload of mechanical excavation and hydraulic excavation, the mechanical excavation time To determine the time of hydraulic excavation, to ensure that the construction progress of the two is consistent, and then to determine the number of hydraulic excavation equipment layout. ...

Abstract

The invention discloses a construction method for earth excavation of a deep foundation pit near a river. The construction method is characterized by comprising the following steps that in the construction process for earth excavation of a deep foundation pit project near the river, mechanical excavation for foundation pit construction and hydraulicking for foundation pit construction are combined according to the actual condition of a foundation pit construction site; hydraulicking is adopted for foundation pit construction when the operating space of a traditional mechanical excavation construction machine is limited or the passing time of an earthwork transport vehicle is limited; and meanwhile, earth is converted into mud during hydraulicking for foundation pit construction, and the mud is directly transported away in a waterway transportation way through a mud ship in the river. Influences on the road traffic around the project are avoided, and the transportation time is not limited. By applying the construction method to construction of a construction project, the earth excavation construction efficiency for the deep foundation pit project can be effectively improved, environmental friendliness is achieved, earth excavation noise is lowered, raising dust pollution is reduced, and time and labor are saved.

Description

Technical field: [0001] The invention relates to a construction method for earthwork excavation of a deep foundation pit near a river. It is mainly used in construction engineering, and it is a construction method for earthwork excavation using hydraulic scour excavation and mechanical excavation combined technology in the earthwork excavation construction of Linjiang deep foundation pit. Background technique: [0002] In the field of construction engineering, when carrying out earthwork excavation of deep foundation pits, large-scale earthwork excavation machinery and equipment are generally used for excavation construction, and earthwork vehicles are used for earthwork transportation. However, in the construction of some projects, due to the limitation of the surrounding conditions of the project, there are the following deficiencies: [0003] 1. The passage time of earthwork transport vehicles is strictly limited, and the transportation efficiency is low; [0004] 2. Th...
