A thin-walled cylindrical soil core pile with wings

Abstract

The invention provides a thin-walled cylindrical soil core pile with wings. The thin-walled cylindrical soil core pile can serve as a supporting body and a temporary facility such as emergency hydraulic rescue, the thin-walled cylindrical soil core pile is made of metal, the middle of the soil core pile is a thin-walled cylinder, a front wing plate and a rear wing plate are arranged at the front end and the rear end of the thin-walled cylinder respectively, a fastening portion is arranged on the front wing plate and used for splicing with a rear wing plate of a front pressing pile in a guiding manner, and a sharp edge is arranged at the bottom of the pile, so that the pile can be smoothly pressed into soil. Various thin-walled cylindrical soil core piles can be sequentially pressed into the soil in a section divided manner, so that the front of one soil core pile is connected with the tail of other soil core pile to form an entire soil core pile, the soil core pile serves as the supporting body when soil is excavated, space stiffness of the pile cylinder and stability of the supporting body are improved by combined actions of the closed thin-walled cylinder, the two wing plates of the pile and a soil core, soil can not be reconstructed, so that surrounding residents cannot be disturbed, construction cost is reduced, the pile can be drawn out after supporting is finished, the pile can be repeatedly used, labor and materials are saved, and environments are protected.

Description

technical field [0001] The invention relates to the construction field, in particular to a thin-walled cylindrical soil core pile with wings used for temporary support. Background technique [0002] In the construction of underground structures, earthwork excavation needs to be provided with supporting facilities in advance, and underground structures also need to be provided with surrounding protective structures. The support facilities for earthwork excavation are independent temporary support bodies, whose purpose is to ensure the stability of the surrounding soil and construction safety during the construction of underground structures. Therefore, the requirements for support facilities are high, but they are discarded after the completion of underground works, which not only wastes manpower and financial resources, but also easily causes pollution and other hazards to the environment. Contents of the invention [0003] In view of the above-mentioned deficiencies in t...
