Embodiment 1

[0043] Example 1, such as figure 1 As shown, the anti-circumvention device includes a baffle 1 and a fixed rod 2, the baffle 1 is rectangular, the height of the fixed plate is 700mm, the fixed rod 2 is L-shaped, and is symmetrically arranged on the top of the baffle 1, The lower end of the vertical portion of the fixed rod 2 is fixed on the baffle plate 1 .

[0044] Further, the fixing plate 1 is a steel plate with a thickness of 10mm.

Embodiment 2

[0045] Embodiment 2, described construction method, comprises the steps:

[0046] Step 1: Making the anti-bypass device:

[0047] 1.1) Process and manufacture the baffle, the height of the baffle is 700mm, the thickness is 10mm, and the width is 10mm smaller than the width of the web of the I-beam joint;

[0048] 1.2) Manufacture the L-shaped fixed rod. The L-shaped fixed rod is made of Ф18 round steel. The length of the curved section of the fixed rod is 500mm, and the length of the straight line is the length of the double-sided weld plus the elevation of the ground wall and the design The difference of the elevation of the top of the concrete surface; the elevation of the top of the concrete surface is the elevation of the concrete surface after overfilling;

[0049] 1.3) The baffle plate and the fixed rod are welded into the anti-flow device by double-sided welding;

[0050] Step 2: Brush the release agent on the concrete-facing surface of the baffle in the anti-circumve...

Abstract

The invention relates to an anti-winding device for repeated use in underground diaphragm wall construction and a construction method of the anti-winding device. The anti-winding device comprises a baffle plate and a fixing rod, the baffle palte is in a rectangular shape, the fixing rod is L-shaped, and the baffle palte and the fixing rod are symmetrically arranged at the top of the baffle plate;the lower end of the vertical part of the fixing rod is fixed on the baffle plate; the construction method comprises the following steps that the anti-winding device is manufactured; a release agent is painted; a steel bar cage with the I-shaped steel joint is manufactured; various parameters of the groove width is detected; the steel bar cage and the I-steel joint are hung, a lock catch box is put down, and a sand belt is refilled; the anti-winding device is installed, and the concrete is poured into a super-irrigation position; and after the concrete in the super-irrigation position reachesinitial setting, and the anti-winding device is pulled out and is washed to be stored. The anti-winding device and the construction method thereof can effectively avoid the flowing concrete at the top of the I-steel, so that the groove formation and the difficult wall brushing are prevented from being caused by concrete caking, the construction quality is improved, meanwhile, the device and the method can be repeatedly used, resources are saved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of ground connection wall construction, and in particular relates to a reusable bypass flow prevention device and a construction method thereof in the construction of a ground connection wall. Background technique [0002] In the construction of deep foundation pits, the form of underground diaphragm wall enclosure has been more and more widely used, and the technological form has become more and more mature. In order to better solve the problem of water seepage and achieve a better water-stop effect, more and more I-beam joints are used in the construction of ground connection walls. By setting the anchor bar between the I-beam and the rear adjacent wall width, an effective connection can be formed between the I-beam and the rear adjoining wall width, and a rigid joint with excellent anti-seepage performance can be formed to overcome the I-beam The joint leakage problem caused by the shrinkage of the concr...
