Further, longitudinal waterstop is located at inverted arch TOC, and longitudinal steel pipe side is fixed on and faced upward
Encircleing the connecing on batch reinforcing bar of short side wall concrete contact, opposite side is fixed on the short side wall concrete of inverted arch and not poured on anchor,
And then longitudinal waterstop is fixed, also allow for inverted arch concrete of constructing.
Further, longitudinal steel pipe both sides tense wire by turnbuckle and fixed.
Further, the intermediate plate is U-shaped steel plate, total length 423mm, a width of 100mm.
Further, the fastener includes clamp nut and bolt, and clamp nut is fixed on intermediate plate both ends, the spiral shell at both ends
Bolt positions through symmetrical abutting waterstop after clamp nut and intermediate plate, reinforces waterstop.
Further, intermediate plate both ends base corresponds in the middle part of waterstop, there is provided short abutment wall inverted arch concrete receives storehouse
Highly, it is ensured that waterstop is embedded placed in the middle.
Further, the spacing of the intermediate plate is 0.5m-1.0m.
Compared with prior art, the beneficial effects of the utility model are as follows：
（1）, the device using construction common used material, it is and simple in construction, make simple, good rigidity is unlikely to deform recyclable
Use, effectively save material consumption is practical, full-featured, reduces engineering cost.
（2）, longitudinal steel pipe bottom is pasted at the top of the device waterstop, intermediate plate base is located just in the middle part of waterstop, there is provided
Short abutment wall inverted arch concrete receives storehouse height, it is ensured that waterstop is embedded placed in the middle.
（3）, the vertical intermediate plate spacing 0.5m-1.0m of the device, can effectively fix waterstop, it is ensured that waterstop outward appearance is straight,
Using turnbuckle can quickly, it is accurate, flexibly waterstop is carried out laterally, vertical positioning.
