Body.
By such scheme, the middle part of described connecting rod is installed on to medium-height trestle.
By such scheme, its length of part that described connecting rod inserts the second wall section is not less than 35 times of connection shank diameters.
By such scheme, the length of described connecting rod is more than the length of straight connector.
By such scheme, described anchoring body is cement mortar or pea gravel concreten.
By such scheme, the axis of described connecting rod and the dead in line of straight connector.
By such scheme, the body of rod surface of described connecting rod is provided with the ribbon projection with body of rod axes intersect.
The beneficial effects of the utility model are：This attachment means and method of attachment can achieve intersegmental firm of underground continuous wall
Property connect, improve the wholeness and whole stiffness of diaphram wall, reduce Wei Lin road number, when adjacent wall section occur vertically uneven
Sedimentation or during horizontal displacement, attachment means described in the utility model and method of attachment can greatly reduce the opening width of the intersegmental seam of wall
With leakage it is ensured that the stability of diaphram wall and construction quality；Compared with traditional rigid structure, this utility model is applied
Work is convenient, and cost performance is high.

Specific embodiment
In order to more fully understand this utility model, with specific embodiment, utility model is made further below in conjunction with the accompanying drawings
Description.
A kind of underground continuous wall section attachment means as described in Figure 1, including from the first wall section 8 steel reinforcement cage（Namely first
Steel reinforcement cage 5）The straight connector 1 of upper end insertion, the outer wall of straight connector 1 is connected with the first the concrete curing of wall section 8；Straight connector 1
Lower end is stretched out from the first wall section 8 steel reinforcement cage side（Specifically the piecing devices from the first wall section 8 steel reinforcement cage side stretch out）, straight set
The lower end port of pipe 1 is provided with plug 2, is blocked by plug 2；Straight connector 1 is built-in with connecting rod 3, and the lower end of connecting rod 3 passes through to be blocked up
2, inside insertion the second wall section 9（Specifically insert in the second wall section 9 steel reinforcement cage, namely in the second steel reinforcement cage 6）, with the second wall
Section 9 concrete curing be integrated connected；It is filled with anchoring body 4, by anchoring body 4 by straight connector 1 in described straight connector 1
Wall and connecting rod 3 are connected.
In this utility model, the length of connecting rod 3 is more than the length of straight connector 1, and the second wall section is inserted in the lower end of connecting rod 3
9 length is not less than 35 times of connection shank diameters.
