Abstract
The utility model provides a metal threaded steel pipe inspection shaft, consisting of a shaft body and a pipe hoop, wherein the surface of the shaft body is provided with threads, and the pipe hoop is arranged at the connecting place of the shaft body and a main pipeline of a drainage system. The metal threaded steel pipe inspection shaft has the advantages that: 1. the overall performance is good, the metal threaded steel pipe inspection shaft consists of the shaft body and the pipe hoop and has a simpler structure than the concrete and brick structure built on spot; 2. the construction cycle is short, the installation is simple and convenient and can be synchronous with the main pipeline, and the installation cycle of the metal threaded steel pipe inspection shaft is only one tenth of that of the masonry type inspection shaft; and 3. the conformability is strong, the metal threaded steel pipe inspection shaft has more evident conformability for poor conditions that a drainage pipeline buried layer is deeper than 4 meters and the ground surface water level is high.
Description
(1) technical field
The utility model relates to the water discharge technology field, is specifically related to a kind of drainage system pipe technology.
(2) background technology
At present, in metal threaded steel pipeline drainage system, pipeline the performance and the life-span that can influence whole drainage system usually be set.And common drainage pipe when laying, exist usually be difficult for " turnings ", can not the indexing setting problem.And on-the-spot build by laying bricks or stones build concrete and the brick structure complexity that the type checking well can provide " turnings " effect by laying bricks or stones, long construction period is installed loaded down with trivial detailsly, and can not carry out synchronously with trunk line, so has drawbacks such as technology bothers, cost is low, and the application scenario is limited.
(3) summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, short construction period, simple installation, can carry out the metal threaded steel pipe manhole that conformability is strong with trunk line synchronously.
The purpose of this utility model is achieved in that it is made up of well body and pipe collar, and the surface of well body is provided with screw thread, and pipe collar is arranged on well body and drainage system trunk line junction.
The utility model also has some technical characterictics like this:
1, described well body comprises pipeline and connector, and connector is arranged on lower end of duct, and pipe collar is arranged on connector and drainage system trunk line junction;
2, described well body is the vertical pillars type, and connector is separately positioned on two ends, the duct bottom left and right sides;
3, described well body rising type in the shape of a spiral;
4, described well body bottom is an enclosed construction, in establish fixedly steel ladder;
5, described well body top is provided with the manhole cover base supporting plate, on the manhole cover base supporting plate manhole cover is set;
6, described well surface is provided with zinc coat or overlay film zinc coat.
The beneficial effects of the utility model have:
1, overall performance is good: metal threaded steel pipe manhole is made up of well body and pipe collar, and the concrete and the brick structure of building by laying bricks or stones than the scene are simple.
2, short construction period, simple installation, can carry out synchronously with trunk line: the installation period of metal threaded steel pipe manhole is just built 1/10 of type checking well by laying bricks or stones.
3, conformability is strong: more than four meters, and water level high mal-condition in the face of land seems more outstanding to metal threaded steel pipe manhole to the drainage pipe buried regions.
Whether the metal threaded steel pipe manhole of the utility model is divided into two kinds in zinc-plated threaded steel pipe manhole and the zinc-plated threaded steel pipe manhole of overlay film by its overlay film.The planform of well is divided vertical pillars type and spiral rising type two classes.When the trunk line diameter adopts vertical pillars type structure during less than metal threaded steel pipe manhole diameter; When the trunk line diameter adopts spiral rising type structure during greater than metal threaded steel pipe manhole diameter.The method of attachment of metal threaded steel pipe manhole and trunk line adopts pipe collar to be connected, and the shaft bottom is an enclosed construction, in establish fixedly steel ladder.Well lid adopts CJ/T121-2000 standard manhole cover, and metal threaded steel pipe manhole top is provided with the manhole cover base supporting plate.
The metal threaded steel pipe manhole of the utility model can be applicable in the metal threaded steel pipeline drainage system. and the manhole that also can be used in various network of underground, piping lane is used.Global design is reasonable, compact conformation.Material is selected galvanized steel plain sheet and peritonaeum galvanized steel plain sheet, and durability can reach 50-100.Introduce in the manufacturing process and the digestion U.S., Korea S's advanced technology, design the series of products of metal threaded steel pipe manhole, factory normalization production, steady quality.
(4) description of drawings
Fig. 1 is the metal threaded steel pipe manhole of a vertical pillars type structural representation;
Fig. 2 is the metal threaded steel pipe manhole of a spiral rising type structural representation.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Embodiment 1:
In conjunction with Fig. 1, present embodiment comprises well body and pipe collar, the surface of well body is provided with screw thread, the well body comprises pipeline 1 and connector 2, pipe collar is arranged on connector and drainage system trunk line junction, connector is arranged on lower end of duct, and the well body is the vertical pillars type, and connector is separately positioned on two ends, the duct bottom left and right sides; Well body bottom is an enclosed construction, in establish fixedly steel ladder; Well body top is provided with manhole cover base supporting plate 3, on the manhole cover base supporting plate manhole cover is set; The well surface is provided with zinc coat.
Embodiment 2:
In conjunction with Fig. 2, present embodiment basic structure is with embodiment 1, and difference is well body rising type in the shape of a spiral; The well surface is provided with the overlay film zinc coat.
