Description
Technical field
The present invention relates to Tunnel Engineering fields, in particular to a kind of tunnel waterstop fixed setting method.
Background technique
Middle buried water stop is the important component of tunnel waterproofing construction, is mainly used for tunnel inverted arch and two lining construction joints
Waterproof measure, when construction must assure that buried water strip position is in the center position of lining thickness, and Transducers Embedded in Concrete portion
Divide the half just for sealing bandwidth, waterstop cannot damage, and line style wants straight.Buried water stop is constructed in tunnel side wall
Method is many in the process, but its main method predominantly uses the fixed waterstop of reinforcing bar card.
Routine is in such a way that self-control reinforcing bar card is fixed, since reinforcing bar is stuck in processing, fixture is welded in fixation procedure and deforms
Larger, the position fixed is the reinforcing bar that binding is completed, and in concreting process, reinforcing bar can be displaced and deviation,
And it is big to continue adjustment difficulty after fixed, often results in that waterstop is damaged during the installation process, it is not straight etc. to apply post-construction deformation
Problem.
Common process is fixed using the every 50cm~100cm setting reinforcing bar card of spacing, every circulation inverted arch (pressing 9m drilling depth)
Two sides abutment wall at least needs to process and weld 20 Reinforcing bar clamps of installation, and not recoverable, material loss are big.
The Reinforcing bar clamp that common process needs processing quantity very big, while needing to be arranged again after welding each fixture
Waterstop, time-consuming, and every circulation inverted arch (by 9m drilling depth) waterstop installation at least needs 4 people while carrying out cooperation to construct,
Reinforcing bar clamp processing, installation and waterstop fixation take a long time.
