Technical field
The utility model relates to a kind of major diameter high pressure duct grouting structure and grouting method, particularly a kind of major diameter high pressure duct grouting structure and grouting method being applied to the realm of building construction.
Background technology
The novel grouting way of high pressure pipeline that the utility model relates to, refers to and is applicable to high water head, large discharge, major diameter and 10m and above diameter, needs the water delivery pressure diversion road of higher-strength steel lining, the pressure pipeline especially in Hydraulic and Hydro-Power Engineering.The head of this kind of derivation conduit or pipeline and the long-pending often comparatively large of diameter, at 3000mm
2above, the steel lining tensile strength of employing is higher than 610MPa.Relative to Traditional project experience, concrete backfill grouting, country rock consolidation grouting and steel plate contact grouting need reserved perforate on steel lining, and perform hole of going forward side by side mouth is reinforced, the making of steel lining and sealing of hole welding procedure complexity, higher to the requirement of environment temperature and humidity, unfavorable to the construction period.Therefore also do not have a kind of structure simple in prior art, do not need reserved perforate on steel lining, simple to operate, effectively can save the major diameter high pressure duct grouting structure of duration.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, do not need reserved perforate on steel lining, simple to operate, effectively can save the major diameter high pressure duct grouting structure of duration.
For solving the problems of the technologies described above, the major diameter high pressure duct grouting structure that the utility model adopts, comprises steel lining, contact grouting pipeline and backfill grouting pipeline; The contact grouting arm that described contact grouting pipeline comprises contact grouting supervisor and formed by contact grouting supervisor branch, described contact grouting supervisor is arranged on the outer wall of steel lining; The backfill grouting arm that described backfill grouting pipeline comprises backfill grouting supervisor and formed by backfill grouting supervisor branch, described backfill grouting supervisor is arranged on the outer wall of steel lining.
Further, also comprise contact grouting stiffening ring, described contact grouting stiffening ring is responsible for contact grouting and is fixedly connected with.
Further, also comprise contact grouting plain steel-bar, described contact grouting plain steel-bar is fixedly connected with contact grouting arm, and the two ends of contact grouting plain steel-bar are fixedly connected with contact grouting stiffening ring.
Further, also comprise backfill grouting stiffening ring, described backfill grouting stiffening ring is responsible for backfill grouting and is fixedly connected with.
Further, also comprise backfill grouting plain steel-bar, described backfill grouting plain steel-bar is fixedly connected with backfill grouting arm, and the two ends of backfill grouting plain steel-bar are fixedly connected with backfill grouting stiffening ring.
Further, also comprise steel mesh reinforcement, described steel mesh reinforcement is arranged on the outer wall of steel lining.
Further, the mouth of pipe of described backfill grouting arm is horn mouth.
The beneficial effects of the utility model are: the utility model is the novel grouting way of major diameter high pressure pipeline, steel pipe can according to underground buried tube Theoretical Design, steel pipe, concrete lining, country rock shared internal water pressure, steel plate thickness is thinner, the dry requirement of steel pipe site operation environment can be reduced simultaneously, thus reduce costs.Owing to not needing plugging holes to weld, can the reduction of erection time, thus play project benefit in advance as generating, water delivery.The process such as perforate are not carried out to high strength steel plate, the performance of high-strength steel can be guaranteed, welding especially can be avoided to occur crackle, and bring potential safety hazard to engineering.
