Example Embodiment

[0030] Example 1:

[0031] reference Figure 1 to Figure 2 This embodiment provides a corbel comprising a vertical I-beam 1, a bottom plate 2, and a reinforcing rib 3. The bottom plate 2 is horizontally disposed and fixed to the lower part of the right flange of the I-beam 1, so The stiffener 3 is vertically fixed at the bottom of the bottom plate 2 and connected to the right flange of the I-beam 1, and further includes a suspension device 4, which is fixed on the left wing of the I-beam 1. Rim upper part.

[0032] For the corbel in this embodiment, since the suspension device 4 is provided on the upper left edge of the I-beam 1, when installing the corbel, it is only necessary to fix the corbel on the top of the steel sheet pile wall through the suspension device 4 , The installation of the corbel can be completed, unnecessary construction steps such as welding are avoided, and the problem of inconvenient construction caused by the need for welding to install the corbel is solved...

Example Embodiment

[0037] Example 2:

[0038] reference Figure 1 to Figure 3 , This embodiment provides a construction method for deep trench support.

[0039] The technical solution of a construction method for deep trench support in this embodiment is as follows:

[0040] A construction method for deep trench support, the steps are as follows:

[0041] In the first step, several steel sheet piles 5 are driven into both sides of the deep groove to be constructed, and steel sheet pile walls are formed on both sides of the deep groove to be constructed, and the top elevations of the steel sheet piles 5 are unified, and the top elevations of the steel sheet piles 5 are unified. Later, the purlin 6 can be installed horizontally, which strengthens the supporting effect of the purlin 6 on the steel sheet pile wall;

[0042] In the second step, excavate a foundation trench between the steel sheet pile walls on both sides, the depth of the foundation trench is greater than the height of the corbel in Example ...

Abstract

The invention provides a bracket and a construction method of a deep trench support so as to solve the problem that the bracket is inconvenient to mount and cannot be repeatedly utilized in the construction process of the deep trench support. Due to the arrangement of a suspending device at the upper part of the left flange of an I steel, when the bracket is mounted, the mounting of the bracket can be finished as long as the bracket is fixed at the top of a steel sheet pile wall through the suspending device, so that unnecessary construction steps, such as welding, are avoided, and the problem of construction inconvenience caused by welding necessity during the mounting of the bracket is solved. As the bracket can be conveniently disassembled after the construction of the deep trench support is finished, the bracket can be cyclically used, and the problem that the existing bracket cannot be repeatedly utilized is solved.

Description

technical field [0001] The invention relates to the current field of deep trench support construction, in particular to a construction method for corbels and deep trench support. Background technique [0002] In the current deep trench support construction, purlins need to be installed inside the steel sheet pile wall to increase the strength of the steel sheet pile wall. Generally speaking, ordinary corbels are used as purlin supports and welded to steel sheet piles. As a result, the installation of the corbel requires on-site welding operations, which is inconvenient for installation, and in the absence of power supply from high-power electrical equipment, it cannot be installed. In addition, once the corbel is welded to death, the corbel cannot be recovered and reused in its original state, which wastes resources. Contents of the invention [0003] The invention provides a construction method for a corbel and a deep trench support to solve the problems that the corbel...
