Abstract
The utility model discloses a draining, exhausting and manhole combined tee joint prefabricated pipe section for a water conveying main pipe. The tee joint prefabricated pipe section comprises a prefabricated pipeline, as well as an exhausting hole, a draining hole and the manhole, which are formed on the peripheral surface of the prefabricated pipeline in a communication manner; the exhausting hole is formed at the upper part of the peripheral surface of the prefabricated pipeline in a communication manner, the draining hole is formed at the lower part of the peripheral surface of the prefabricated pipeline in a communication manner, and the manhole is formed on the middle lower side of the peripheral surface of the prefabricated pipeline in a communication manner. According to the pipe section, the exhausting hole, the draining hole and the manhole are formed in the same prefabricated pipeline in advance, the site construction difficulty is reduced greatly, multiple functions of maintenance, evacuation, exhausting and the like are achieved at the same time, the quantity of working wells can be reduced greatly through the application of the water conveying main pipe of the prefabricated pipe section, and further, the construction cost is reduced, construction maintenance of a plurality of parts can be conducted in the same working well at the same time, and the unified management and maintenance of the water conveying pipe are more convenient.
Description
Technical field
The utility model relates to the drainage pipe facility technology field in the engineering of paddling, and relates in particular to a kind of draining for delivery main, exhaust, the prefabricated tube coupling of manhole combination threeway.
Background technique
Along with China's economic development, increasing city begins to build the large-scale water delivery engineering of long distance.In long distance water transfer project, need to be on different tube couplings on the delivery main parts such as installation of relief valve, outlet valve, manhole.In present water delivery engineering, the setting position of all parts of delivery main disperses, parts on the corresponding diverse location all need to arrange separately an active well, great in constructing amount, and be unfavorable for unified management, the maintenance of delivery main, simultaneously also take more space, improved engineering cost.
Therefore, those skilled in the art is devoted to develop a kind of draining for delivery main, exhaust, the prefabricated tube coupling of manhole combination threeway to address the above problem.
The model utility content
Because the defects of prior art, technical problem to be solved in the utility model provide a kind of for long apart from can realize simultaneously on the Large Diameter Pipeline delivery main overhauling, the prefabricated tube coupling of combination threeway of the multiple functions such as emptying, exhaust.
For achieving the above object, the utility model provides a kind of draining for delivery main, exhaust, the prefabricated tube coupling of manhole combination threeway, comprises prefabricated pipeline, and connects exhaust port, weep hole and the manhole that is arranged on the side of described prefabricated pipeline week.Described exhaust port connects the top that is arranged on side of described prefabricated pipeline week, described weep hole connects the bottom that is arranged on side of described prefabricated pipeline week, described manhole connects a centre side on the lower that is arranged on side of described prefabricated pipeline week, setting position is more reasonable, realize to a greater extent the performance of prefabricated pipeline, improve applicability of the present utility model.
The utility model sets in advance exhaust port, weep hole and manhole on same prefabricated pipeline, reduced greatly the difficulty of site operation, realize simultaneously the multiple functions such as maintenance, emptying, exhaust, because with being arranged on the same tube coupling of exhaust port, weep hole and manhole compactness, the delivery main of using the prefabricated tube coupling of the utility model will greatly reduce the magnitude setting of active well, then realize the decline of engineering cost, and can in same active well, carry out Construction and Maintenance to a plurality of parts simultaneously, more be convenient to unified management, the maintenance of delivery main.
Better, be provided with outward extending exhaust fitting on the described exhaust port, make things convenient for externally connected exhaust pipe, further reduce the difficulty of site operation.
Better, be provided with outward extending emptying pipe joint on the described weep hole, length and the angle of extension can be set as required, improve drainage performance.
Better, be provided with outward extending current pipeline on the described manhole, length and the angle of extension can be set as required, further facilitate operator and pass in and out and carry out maintenance and inspection in the delivery main.
Better, the end portion of described prefabricated pipeline is provided with recessed head or the plush copper of being convenient to adjacent described prefabricated pipeline splicing, by recessed head or plush copper are set as connecting head in the termination, can recessed head or plush copper all be set in two ends, arrange to realize being connected of plush copper and recessed head by the interval, also at one end head arranges recessed head, another termination arranges plush copper, directly recessed head, the plush copper with adjacent tube coupling connects, and realizes the flexible connection of prefabricated tube coupling of the present utility model on delivery main.
In sum, the utility model be a kind ofly can realize simultaneously overhauling, the prefabricated tube coupling of combination threeway of the multiple function such as emptying, exhaust, be applied in the workload that not only can reduce the engineering site construction on the delivery main, and the volume that can effectively reduce active well takes up room and reduces the magnitude setting of active well, greatly reduces engineering cost; In addition, the utility model connects flexibly, and it is convenient to install, overhaul, and can move more safely and effectively under the operating modes such as installation, debugging, cleaning and maintenance.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand fully the purpose of this utility model, feature and effect.
