Description
Technical field
The utility model relates to constructing tunnel guarded drainage technical fields, more particularly, to a kind of anti-water system of construction joint of tunnel
System.
Background technique
With the development of national economy, ratio shared by Tunnel Engineering is incrementally increased in road construction.In railway tunnel
In construction, with cognition universal in the industry, since necessity of construction is divided into inverted arch and arch wall lining cutting two parts, short abutment wall is made for lining cutting
A kind of customized noun is formed to the part structure between inverted arch and two linings in the construction process for unit in charge of construction, thus also
Longitudinal construction joint is produced, in the guarded drainage technical measures in tunnel, construction joint is all made of the double-deck Water stop structure, i.e. back sticking type
+ middle buried water stop.Construction joint is the weak link of tunnel water proofing, and waterstop is necessarily mounted at the centre of lining thickness due to it
And must assure that installation quality, mounting height, straight degree and verticality are required to very stringent, the direct shadow of quality of installation quality
Tunnel water proofing quality is rung, in terms of the railway tunnel traffic-operating period that the current country has been completed, there are still percolating water phenomenons, influence tunnel
Traffic safety and hole in equipment normal use.
The rubber fastening band generallyd use in lining construction is main raw material(s) with natural rubber and various rubber.
However being limited since waterproof/drainage structure is designed with waterstop web length for lining cutting position, it is necessarily buried in appearance, back sticking type sealing
Band overlapped require.Since the tow sides surface of middle buried water stop has fin, the front face surface of back-adhering waterstop has
Have fin, docking when existing method there are two types of: one is use heat cure mold carry out heat connect, one is using bonding agent into
Row cold junction.Live heat connect vulcanization docking, be using with the matched heat cure mold of waterstop and the situ vulcanized heat of raw stock
It connects, difficulty of construction is big, but docks effect ideal, is suitble to require construction quality stringent project, is not suitable for being widely used to promote.
It is that the section sanding machine of connector needs waterstop using the dedicated cold joint glue of rubber fastening band using bonding agent cold junction
5~10 centimetres, cementing compacting are polished, has the advantages that intensity is high, solidification is fast, can reach common engineering quality requirement.
But using in the method for bonding agent cold junction at the construction field (site) use process, since the fin at banjo fixing butt jointing needs to carry out
Neat cutting and whole polishing, the cumbersome and quality that operates control is not easy, and then leaves more percolating water hidden danger in joint,
The weak spot of percolating water is finally formed at construction joint, and then causes very big security risk for the operation security in tunnel later period.
Summary of the invention
In order to realize the main purpose of the utility model, the utility model provides a kind of overlap joint simple and fast and waterproof effect
Good construction joint of tunnel waterproof system.
