Embodiment Construction

[0018] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Insert 2 lattice columns in the steel cage of the underground diaphragm wall as an example to illustrate the specific implementation method of the present invention, please refer to the attached figure 1 , first make the steel cage for the underground diaphragm wall by normal welding according to the design requirements (not shown in the figure), and then erect the auxiliary lifting cage 1 above. The space where the longitudinal truss 5 is about to be inserted and installed with lattice columns is called the enclosed space. A plurality of guide ribs 3 are welded horizontally and symmetrically on the longitudinal truss 5 inside the enclosed space. Lattice columns are planned to be inserted deep into the underground diaphragm wall. The longitudinal truss 5 combined with the guide rib 3 and the main rib 4 enclose to form a guide groove, a...

Abstract

The invention discloses a construction method for installing underground lattice column. The method includes the steps that a reinforcement cage of an underground diaphragm wall and a craning auxiliary cage are produced firstly, wherein the craning auxiliary cage comprises a main reinforcement and a plurality of longitudinal trusses vertically connected with the main reinforcement, a plurality of guide ribs are horizontally and symmetrically welded on the longitudinal trusses, and a guide groove is defined by the main reinforcement and the longitudinal trusses which are combined with the guide ribs; positions of the longitudinal trusses are adjusted so as to enable space defined by the longitudinal trusses combined with the guide ribs to be larger than the width of the lattice column to be installed in a direction perpendicular to the longitudinal trusses; a guide device is detachably fixed in the guide groove, and the top elevation of the guide device is flushed with the ground elevation; a hanging steel bar is welded at the top of the lattice column which is then craned through the hanging steel bar and placed in the guide device, and the hanging steel bar is fixed until the lattice column is craned to a designed elevation; and the guide device is dismounted, concrete is poured on the underground diaphragm wall, and the construction is completed.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for inserting lattice columns underground. Background technique [0002] As an important form of enclosure structure in deep foundation pit engineering, underground diaphragm wall has been widely cited in the field of rail transit engineering construction in major cities in my country in recent years. With the expansion of rail transit station space, the structural form has become more complex and the construction difficulty has gradually increased. The function of the underground diaphragm wall has gradually developed from a temporary enclosure structure to a permanent enclosure structure and the longitudinal support structure of the main structure. [0003] Usually the underground station is constructed by cover-excavation method due to the progress of the construction period, and the conventional cover-excavation support column is constructed by the metho...
