Conventional spare interface form has：1 prearrangement of deformation amount stitches waterstop+masonry or the protection of concrete periphery, this form
Later stage easily makes waterstop damaged when excavating and remove periphery protection；2 prearrangement of deformation amount stitch waterstop+connector part waterproof coagulation
Soil, this form waterstop under soil pressure effect can be deformed, and excavate pole when cutting connector part water-proof concrete
Easily make waterstop damaged；3 reserved interface channel interfaces, the later stage cuts part concrete, in New-old concrete interface construction joint
Place sets water expandable waterstop, then construction Deformation seam, and this form later stage cuts concrete and more bothered, only set at construction joint
Put the easy seepage of water expandable waterstop.
At present, also no one kind can early stage have good defencive function, later stage convenient construction ensures construction quality, and energy
The prearrangement of deformation amount for having fine water resistance sews up mouth structure.
The content of the invention
The utility model purpose is：A kind of unfavorable problem for solving conventional spare interface form is provided, can early stage have very
Good defencive function, later stage convenient construction ensures construction quality, and the underground engineering prearrangement of deformation amount that can have fine water resistance again is stitched
Connecting interface structure.
The technical solution of the utility model is：A kind of underground engineering prearrangement of deformation amount stitches connecting interface structure, in new/old coagulation
The interface formation tongue and groove of soil, and left plate waterstop is reserved in old concrete, at the tongue and groove, in left plate sealing
The right steel plate water stopper of welding is taken, the right steel plate water stopper is located in the novel concrete, and transversal in the novel concrete
Face be provided with movement joint, in the movement joint be provided with the vertically disposed detachable waterstop of the movement joint, while described
In detachable waterstop two ends embedment both sides novel concrete.
As preferred technical scheme, old interior arrangement of reinforcement is provided with the old concrete, is provided with the novel concrete
Arrangement of reinforcement in new, and old interior arrangement of reinforcement in old concrete extends into novel concrete and is welded and fixed with new interior arrangement of reinforcement.
As preferred technical scheme, inverted U cover is provided with the outside of the movement joint, the inverted U cover two ends are by burying
Coordinate in the barb in the novel concrete of both sides and nut and fix.
A kind of underground engineering prearrangement of deformation amount stitches connecting interface preparation method, comprises the following steps：
Step 1) in old concrete, positioned at the reserved left plate waterstop of intersection of new/old concrete, and new/old
The intersection of concrete is embedded to trapezoidal wooden unit；
Step 2) cut the old concrete and trapezoidal wooden unit beyond trapezoidal wooden unit and formed in the intersection of new/old concrete
Tongue and groove；
Step 3) right steel plate water stopper is welded on left plate waterstop, novel concrete is then poured, and in novel concrete
Movement joint is reserved on cross section, detachable waterstop is embedded in the both sides novel concrete of movement joint.
As preferred technical scheme, new/old interior arrangement of reinforcement is embedded with respectively in the new/old concrete, and it is new/old interior
Arrangement of reinforcement is welded.
The utility model has the advantages that：
1. the utility model reserves left plate waterstop in old concrete, at the tongue and groove, it is to avoid the later stage cuts
Damage to waterstop, tongue and groove interface solves conventional spare interface form not to strengthen the shearing resistance of new/old concrete
Sharp problem, can early stage have good defencive function, later stage convenient construction ensures construction quality, can there is fine water resistance again；
2. the utility model early stage reserves trapezoidal wooden unit, so that the later stage conveniently cuts concrete.
