It is laid with the special GCL composite components milling roller of vertical seepage control completed, product is rolled and is attached on cell wall, it is convenient
Follow-up decentralization connector case and junction block；Meanwhile rolling rear overlapping regions and being tightly combined, be conducive to promote overlapping regions barrier properties
Can, overlapping regions smears overlap joint cream, and it is more preferable to roll rear anti-seepage effect；Further, since close segments construction is because be not required to decentralization connector
Pipe fitting case, GCL composite components roll after the completion of being laid with using milling roller, ensure that GCL composite components are adherent, overlapping regions fitting
Closely, meanwhile, ensure that pulp flow direction is consistent with lapping direction when pouring, prevention is poured grouting material and generated to GCL composite components
Disturbance；
Milling roller can be an individual mechanical device, can also be combined with GCL laying apparatus；Milling roller is long
Degree should be able to adapt to the variation of trench length；
After GCL composite components transfer to projected depth, connector case is transferred in overlap, connector is closely placed on the inside of connector case
It manages (can not also put junction block), overlapping regions is entered with blocking backfill material, ensures that the second width GCL can be overlapped smoothly；Connector
Pipe and connector case can reduce the clear slot difficulty of overlapping regions, while material waste caused by capable of reducing clear slot and compound to GCL
The damage of component；
Connector case height is not less than gash depth, and connector case length is not less than overlapping regions length, and connector case width is less than
2~5cm of groove width transfers convenient for connector case；The connector pipe diameter is less than 2~5cm of groove width, and length is not less than slot
It is deep；
Connector pipe diameter and connector case width should determine that diameter and width are slightly less than groove width, just according to groove width
It is transferred in junction block and connector case, while maximum possible blocking backfill slurry outflow；
Since junction block is circle, connector case is rectangular, after junction block is close to connector case, therebetween or there is seam
The backfill slurry of gap, perfusion can enter gap, and after extracting junction block and connector case, the backfill material demand in gap is removed, with
Ensure free from admixture in overlapping regions；During clear slot, grab claw is readily accessible the GCL being laid with, and is easy to cause product
Damage；Overlapping regions >=45cm, junction block, connector case and the contacts site GCL smear overlap joint agent, on the one hand slurry coat method are cooperateed with to carry
Overlapping regions entirety barrier performance is risen, lubricating action is on the other hand played, junction block and connector case and production are divided into and pulled up in reduction
Friction between product, protects product not to be damaged；
Overlap joint agent can be lotion made of bentonite adds water to stir, but if needing overlapping regions that can bear centainly
A certain amount of cement can be then added in external force in swelling soil cream；
Corner is laid with GCL composite components and needs special suspender, to ensure that GCL composite components and corner wall are close
Fitting, suspender angle, bottom end counterweight steel plate angle be adjusted to consistent with the angle of corner, with crane by the compound structures of entire GCL
Part is slowly put into groove after slinging；
To ensure that construction safety and vertical laying effect, corner's construction should construct under calm or breeze conditions；
When there are GCL composite component overlaps in casting area, it should ensure that mud flow direction is consistent with lapping direction when pouring,
Reduce disturbance of the casting process to overlapping regions.
Embodiment two
Junction block, connector case are substituted for two-in-one connector case, two-in-one connector can case once pull up after can enter under
Procedure is constructed, and construction efficiency is improved.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody the principles of the present invention to some variations that some of which part may be made, and belong to the utility model
Protection domain within.
