Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

A kind of order type manhole, comprises well seat 100, pit shaft 200, inlet pipe 300, goes out pipe 400, posting 500, bar 101 of standing, draining ring 600 and gutter 700.

Described inlet pipe 300 and go out pipe 400 level and concentric is arranged, described pit shaft 200, inlet pipe 300 and go out pipe 400 and be intersected in well seat 100, and pit shaft 200 is erect and is arranged.

Described posting 500 is inserted in inlet pipe 300 and goes out the pipeline opening of pipe 400; Described posting 500 comprises outer shroud 501, floor 502 and inner ring 503.The annulus that outer shroud 501 and inner ring 503 are arranged for concentric.Described floor 502 radial shelf is located between outer shroud 501 and inner ring 503.Inner ring 503 is fixed in described floor 502 the inner, and outer shroud 501 is fixed in outer end.

From the electric power cable that inlet pipe 300 is introduced, enter out pipe 400 through after posting 500.The setting of posting 500, avoids already installed cable and is subject to extraneous upset.

Described well seat 100 erection has the station bar 101 of level.Described station bar 101 is positioned at below posting 500.To stand the setting of bar 101, for operating personnel provides the position of standing.

Described well seat 100 sidewall offers the drain hole 102 of equidistant equal altitudes; The height of described drain hole 102 lower than inlet pipe 300, go out pipe 400 and station bar 101; Described well seat 100 outer wall is arranged with draining ring 600; Drain chamber 601 is formed between described draining ring 600 and well seat 100; Described draining ring 600 covers drain hole 102, and drain hole 102 and drain chamber 601 are interconnected; Described draining ring 600 is connected with gutter 700.Described drain hole 102 is around the equidistant arrangement of axis circumference of well seat 100.

The ponding gathered bottom well seat 100, enters drain chamber 601 by drain hole 102, finally discharges from gutter 700.When rainwater enters from pit shaft 200, rainwater can gather at well seat 100.The setting of drain hole 102, draining ring 600 and gutter 700, avoids the rising of water accumulation level, impacts electric power cable.

As preferably, a kind of order type manhole, also comprises lifting cover 800; Bulge loop 201 is equidistantly placed with above described pit shaft 200; Described lifting cover 800 is sheathed on pit shaft 200 top; Equidistant arrangement is provided with and the scrobicular ring 804 adapted with bulge loop 201 bottom described lifting cover 800; Described bulge loop 201 is embedded at scrobicular ring 804.

The position being sheathed on pit shaft 200 by adjusting lifting cover 800 adjusts the height of this manhole, in order to adapt to the laying operating mode of different depth, adds the compliance of product.

The inwall of described lifting cover 800 is provided with the upper solid ring 805 of level and lower solid ring 807; Be folded with between described solid ring 805 and lower solid ring 807 and import plate 900; Described importing plate 900 offers entrance hole 901.

The lower surface of described solid ring 805 is provided with ramp 806; The upper surface of described lower solid ring 807 is provided with lower inclined plane 808; The spacing of described ramp 806 and lower inclined plane 808 radially outward reduces.Ramp 806 is radial low inside and high outside; The inside low outer height in lower inclined plane 808 footpath, be convenient to slip into when installing import plate 900, and after playing installation, location imports the effect of plate 900.

Described entrance hole 901 comprises hole 902 and lower opening 903; The inwall in described upper hole 902 is cylindrical; Described lower opening 903 is arranged with upper hole 902 concentric, and the inwall of lower opening 903 is in the truncated cone-shaped of standing upside down.New cable penetrates from entrance hole 901, thus enters into manhole inside.The setting of entrance hole 901, plays the effect of positioning cable, and make the arrangement of cable more orderly on the one hand, on the other hand, similar cable can import from same entrance hole 901, facilitates cable to do functional differentiation.The entrance hole 901 temporarily do not used can plug blocked shot 904.The setting of lower opening 903, in order to locate blocked shot 904, prevents blocked shot 904 from sinking.The setting of blocked shot 904, enters this manhole in order to prevent rainwater or other foreign material.

Described lifting cover 800 overlaps 801 mutual being fitted together to by two semicircles and forms; One end of described semicircle cover 801 is provided with bayonet socket 802, and the other end is provided with the coadapted card convex 803 with bayonet socket 802; Snap ring 809 is arranged with outside described lifting cover 800; Described snap ring 809 is equipped with screw rod 810; Described screw rod 810 is connected with backstay 811 through snap ring 809 rear thread.

Snap ring 809 be combined with each other fixing in order to make two semicircle covers 801.Exterior object is fixed on, as roadbed in the outer end of described backstay 811.By the mutual rotation of screw rod 810 and backstay 811, adjust the orientation of lifting cover 800.

The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technical scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection domain of the present utility model.
