Embodiment Construction

[0036] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0037] As shown in the accompanying drawings, the present invention discloses a soil-moving device for deep foundation pit excavation, which mainly consists of a first hoist 6, a second hoist 1, a steel wire rope 7, a triangular support tower 8, and a reinforced concrete anchor block 2 , cable stay 10, steel plate base 4, steel pile 12, cement-soil reinforcement area 11 and earth moving box 13 constitute.

[0038] Two triangular support towers 8 are symmetrically installed on the ground on both sides of the top of the foundation pit 14, the height of the 8 triangular support towers is 2~3m, and the included angle between the steel pipes in the triangular support tower 8 and the ground is 45° ~60°. The triangular support tower 8 can also be changed int...

Abstract

The invention discloses an earth moving device and method for deep foundation pit excavation. Ground surfaces at two side at the top of a foundation pit are respectively provided with supporting tower frames; steel wire ropes are connected between the two supporting tower frames; a first winch is arranged on the steel wire ropes; the tail end of a rolling rope of the first winch is connected with an earth moving box in a hanging mode through a hook; the ground surface at the outer side of each supporting tower frame is provided with a second winch; a rolling rope of the second winch passes through the supporting tower frames, and is fixedly connected with the first winch; the first winch places the earth moving box at the bottom of the foundation pit for earth filling; and after earth is filled fully in the earth moving box, the first winch hangs up the earth moving box, then the earth moving box is pulled close to the supporting tower frames through the second winch on the ground surface, and the earth can be moved away by using earth moving vehicles stopped out of the foundation pit. According to the earth moving device and method, for the foundation pit, especially the deep foundation pit, the earth volume can be moved safely and reliably; and meanwhile, the construction manufacturing cost also can be saved, and the construction period that the earth volume of the foundation pit is moved externally can be shortened.

Description

technical field [0001] The invention relates to a device and method for transporting excavated materials in civil engineering, in particular to an excavation and soil transporting device and soil transporting method suitable for deep foundation pits such as house construction and subway stations. Background technique [0002] At present, the method of soil transportation for deep foundation pits such as housing construction and subway stations is mainly by building temporary trestle bridges or soil transportation channels connecting the inside and outside of the foundation pit. [0003] Among them, building a temporary trestle will increase the cross-sectional area of ​​horizontal support and vertical support, increase the amount of steel and concrete, and increase the cost of the project; and building a trestle also requires adding temporary columns, which will occupy the working space of excavating construction machinery and reduce the cost of construction. Improve the wor...
