Description
Technical field
The utility model relates to constructing tunnel guarded drainage technical fields, specifically, being to be related to a kind of middle buried water stop
Connector.
Background technique
In the construction of railway tunnel, with cognition universal in the industry, lining cutting is divided into inverted arch and arch due to necessity of construction
Wall lining builds two parts, and short abutment wall is unit in charge of construction in the construction process to the part structure between inverted arch and secondary lining
Address, thus also just produces longitudinal construction joint, in the guarded drainage technical measures in tunnel, the waterproof system of construction joint is all made of
The double-deck Water stop structure, i.e. back-adhering waterstop and middle buried water stop, wherein in buried water stop include intersect vertically it is vertical
To buried water strip and circumferential buried water strip.Construction joint is the weak link of tunnel water proofing, and waterstop must be installed due to it
Lining thickness centre and must assure that installation quality, mounting height, straight degree and verticality are required to very stringent, installation
The quality of quality directly affects tunnel water proofing quality, and in terms of the railway tunnel traffic-operating period that the current country has been completed, there are still infiltrations
Drainage, influences the normal use of equipment in the traffic safety and hole in tunnel, thus at present the mounting process of waterstop not at
It is ripe.
The rubber fastening band generallyd use in lining construction is main raw material(s) with natural rubber and various rubber.
However at short abutment wall position, since waterproof/drainage structure designs, there is longitudinal buried water strip and circumferential buried water strip intersection
Form.
As shown in Fig. 2, longitudinal buried water strip 101 at " cruciform joint " is identical with circumferential 102 structure of buried water strip,
There are six fins in the front of longitudinal buried water strip 101, and also there are six fins at the back side.Overlap joint at existing " cruciform joint "
There are two types of processing methods: one is using heat cure mold to carry out heat to connect, one is carry out cold joint using bonding agent.
To the method that heat connects vulcanization connector on site, using live with the matched heat cure mold of waterstop and raw stock
Heat of vulcanization connects, and difficulty of construction is big, but connector effect is ideal, is suitble to require construction quality stringent project, is not suitable for pushing away extensively
It is wide to use.
For the method for use bonding agent cold junction, stop using the dedicated cold joint glue of rubber fastening band, using splicing processes handle
Water band needs the section of connector to polish 5 to 10 centimetres, cementing compacting with sanding machine, with intensity height, solidifies fastly excellent
Point can reach common engineering quality requirement.
But bonding agent is used to carry out the method for cold joint at the construction field (site) in use process, due to convex at " cruciform joint "
Rib needs to carry out neat cutting and whole polishing, and the cumbersome and quality that operates control is not easy, and then leaves in joint more
Percolating water hidden danger.The weak spot of percolating water is finally formed at construction joint, and then is caused greatly for the operation security in tunnel later period
Security risk.
