Abstract

The utility model relates to a sewage water inspection well, which comprises an inspection well body (1), wherein the inspection well body (1) is an integrally-precast cement inspection well, the bottom of the inspection well body (1) is arc-shaped, the radian R of the inspection well body is 550 to 1000 mm, a first water inlet pipe (2), a second water inlet pipe (3), a third water inlet pipe (4) and a water outlet pipe (5) are arranged on the inspection well body (1), and the water outlet pipe (5) is lower than the third water inlet pipe (4) and is arranged in a position opposite to the third water inlet pipe (4). The sewage water inspection well has the advantages of simple structure, convenience in construction, long service life and low cost.

Description

The sewage inspection shaft

Technical field

The utility model belongs to a kind of city and construction area internal drainage field, is specifically related to a kind of sewage inspection shaft.

Background technology

At present, it is to build by laying bricks or stones with common brick that traditional draining inspection shaft and road limit rainwater castor basement advance, and cement is smeared and formed, and not only construction is complicated, and weathering comes off in the inspection shaft body, and the well body sinks, and causes the road surface local collapse easily, and its application life is short, and cost is higher, and maintenance is inconvenient.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, easy construction, long service life, the sewage inspection shaft that cost is low.

The technical solution of the utility model: a kind of sewage inspection shaft, it comprises the inspection shaft body, described inspection shaft body is integral prefabricated good cement inspection shaft, the bottom shape of inspection shaft body is an arc, its radian R is 550～1000mm, basement advances body and is provided with first water inlet pipe, second water inlet pipe the 3rd water inlet pipe and outlet pipe, and outlet pipe is lower than the 3rd water inlet pipe, and is arranged on the position relative with the 3rd water inlet pipe; Outlet pipe is 20～30mm apart from inspection shaft body inwall bottom apart from I, the 3rd water inlet pipe is 30～40mm apart from inspection shaft body inwall bottom apart from J, the equal diameters of first water inlet pipe and the 3rd water inlet pipe, its diameter is 150～250mm, the diameter of the 3rd water inlet pipe is 300～400mm, the diameter of outlet pipe is 250～300mm, and the inner diameter D of inspection shaft body is 1100～2000mm, and the upper end bore C of inspection shaft body is 600mm; The top of inspection shaft body is 800～5000mm apart from its inwall diapire apart from E, first water inlet pipe, second water inlet pipe are 400～3000mm apart from inspection shaft body inwall bottom apart from F, the top of inspection shaft body is 400mm apart from its wall body bending part apart from G, and the thickness H of inspection shaft body wall is 60～140mm.

Described inspection shaft body is provided with plural first water inlet pipe.

The utility model compared with prior art has following beneficial effect: 1, construction cost is lower, and cement one-shot forming goods are saved a large amount of constructional materialss than traditional inspection shaft, have saved cost of manufacture, and the more traditional inspection shaft of construction earth volume reduces; 2, construction period has been shortened in easy construction; 3, non-efflorescing cementitious, do not come off, do not sink, reduced maintenance cost, prolonged application life.
