Abstract

The utility relates to construction technology for underground diaphragm wall , proposes a underground diaphragm wall joint ---- an I-steel joint improvement. I-steel joint is provided with a slot end plate one side of which is provided with two slot side plates whose outer side has 50-80mm shrinkage away from side of slot side plates; another side of slot end plate is provided with a ribbed slab at middle part. Rib slab side is used in first-stage wall section; the first-stage slot section comes into being; then rib slab can be welded together with first-stage wall steel bar cage and simultaneously placed in first-stage slot section; then concrete is poured into first-stage slot section to form first-stage wall section with joint, subsequently second-stage wall is constructed according to existing technology. Compared with the prior arts, the utility enables connection fastness of first-stage wall section and second-stage section, largely promotes antiseepage capability of underground diaphragm wall, saves steel, and is easily manufactured and assembled.

Description

A kind of underground continuous wall connector

Technical field

The utility model relates to diaphragm wall engineering construction technology.

Background technology

Diaphragm wall is meant the underground structure that is coupled together by joint by a plurality of unit body of wall.Because technology, during construction, carry out the wall section construction of first phase unit earlier, the second stage of unit wall section of constructing then, one, the second stage of unit wall section connects by joint.Because one, the second stage of unit wall section concrete is cast in the different periods and carries out, therefore can produce cold seam in the joint, become wall after, artesian water is just by this position seepage.

Joint commonly used at present mostly is the i iron joint, because its second stage of steel plate is positioned at wall outer side, and objectively forming one influences its anti-seepage effect around oozing passage, and steel quantity consumption is big, makes complicated behind the one-tenth wall.

The utility model content

The purpose of this utility model is a kind of underground continuous wall connector of design, and it has that the antiseepage ability is strong, steel using amount is few and is easy to make characteristics such as installation.

The technical solution of the utility model is as follows:

A kind of underground continuous wall connector, be the improvement of i iron joint, it is characterized in that: a groove end plate is arranged, and a side of groove end plate is provided with two blocks of trough rim plates, there is the punctured bit of 50～80mm trough rim plate outside from groove end plate limit, the opposite side centre position of groove end plate is provided with a floor.

During use, floor side of the present utility model is used for first phase wall section, after the grooving of first phase groove section, floor of the present utility model and first phase wall reinforcing cage can be welded together, put into first phase groove section simultaneously, then concrete perfusion makes to form and has the first phase wall section of belt lacing in first phase groove section, then by the prior art the second stage of wall section of constructing.

With existent technique contrast, the utility model makes one, the second stage of wall section firm and reliable connection, can improve the antiseepage ability of diaphragm wall greatly, and steel using amount few, be easy to make and install.

Description of drawings

Fig. 1 is a schematic cross-section of the present utility model;

Fig. 2 is the utility model user mode reference diagram;

Fig. 3 is a stereogram of the present utility model.

The specific embodiment

With reference to figure 1 and Fig. 3, as shown in Figure 1, a kind of underground continuous wall connector that the utility model proposes, it has a groove end plate (2), one side of groove end plate (2) is provided with two blocks of trough rim plates (3), there is the punctured bit (22) of 50～80mm trough rim plate (3) outside from groove end plate (2) limit, the opposite side centre position of groove end plate (2) is provided with a floor (1).

In conjunction with reference to figure 2, during use, floor 1 side of the present utility model is used for first phase wall section, after the grooving of first phase groove section, floor 1 of the present utility model can be welded together with first phase wall reinforcing cage, put into first phase groove section simultaneously, then concrete perfusion makes to form and has the first phase wall section of belt lacing in first phase groove section, then by the prior art the second stage of wall section of constructing.

As can be seen from Figure 2, the utility model can be connected firmly first and second phase wall section, and it is strong to make the diaphragm wall that is connected have stronger antiseepage ability, has the steel of saving simultaneously and is easy to advantages such as manufacturing and installation.

Claims

1. underground continuous wall connector, it is the improvement of i iron joint, it is characterized in that: a groove end plate (2) is arranged, one side of groove end plate (2) is provided with two blocks of trough rim plates (3), there is the punctured bit (22) of 50～80mm trough rim plate (3) outside from groove end plate (2) limit, the opposite side centre position of groove end plate (2) is provided with a floor (1).

2. underground continuous wall connector as claimed in claim 1 is characterized in that: floor (1) side combines with first phase wall section.
