Abstract
A sewage inspection well belongs to the technical field of municipal underground construction and is characterized in that an inspection well wall (4) is cylindrical; at least two water drainage pipeline ports (5) are arranged on the cylindrical inspection well wall (4); a well bottom (6) is arranged at the bottom of the cylindrical inspection well wall (4); a cylindrical inspection well outlet pipe well wall (2) is connected to the upper part of the cylindrical inspection well wall (4); a well outlet well cover (1) is arranged at the top of the cylindrical inspection well outlet pipe well wall (2); and a crawling ladder (3) is fixedly mounted downward between a well outlet and the well bottom along the cylindrical inspection well outlet pipe well wall (2) and the inspection well wall (4). The inspection well has the advantages of high strength, good heat insulation, ageing resistance, lower possibility of leakage and simple installation procedures, prolongs the service life of the sewage inspection well and pipelines, lowers the maintenance cost and can be extensively applied to underground drainage construction.
Description
Technical field
The utility model relates to municipal underground construction technical field, specifically a kind of sewage manhole.
Background technology
Sewage manhole of the prior art adopts brick to mix the old way of building by laying bricks or stones substantially, is subject to freeze injury when occurring the seepage winter severe cold easily.Existing problems are long construction periods, and engineering efficient is low, and because the physicochemical property instability of brick or cement, in use seepage and damage are more serious, especially because the general degree of depth of blow-off line is all darker, a lot of constructions are built wells substantially all under underground water, thereby difficulty of construction is big, quality more be cannot say for sure to demonstrate,prove, and the direct polluted underground water of seepage appears, if rich groundwater causes underground water to flow from leak source is counter, cause sewage load to strengthen and serious waste, cause underground water to run off in a large number.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of integral type sewage manhole is provided.
The purpose of this utility model realizes by following measure:
A kind of sewage manhole, mainly be to go out the well casing borehole wall 2, cat ladder 3, the manhole borehole wall 4 by manhole, form, it is characterized in that the manhole borehole wall 4 is cylindrical, have 2 drainage pipe interfaces 5 on the cylindrical manhole borehole wall 4 at least, the cylindrical manhole borehole wall 4 bottoms are shaft bottoms 6, the cylindrical manhole borehole wall 4 tops are connected to cylindrical manhole and go out the well casing borehole wall 2, cylindrical manhole goes out the well casing borehole wall 2 tops the well head of going out well lid 1, goes out the well casing borehole wall 2, the manhole borehole wall 4 to being installed with cat ladder 3 shaft bottom from going out well head to the lower edge manhole.
The utility model compared with prior art has following beneficial effect: the utility model utilizes PE material or glass-reinforced plastic material, have intensity height, good heat preservation performance, characteristics such as ageing-resistant, during construction, manhole drainage pipe interface is connected with the drainage pipe sealing, easy to leak not, installation procedure is simple, prolongs the application life of sewage manhole and pipeline, reduces maintenance cost.And simple in structure, easily processing, but mass production can be widely used in underground drainage project.
Description of drawings
Fig. 1 is a sewage manhole cross-sectional view;
Fig. 2 is a sewage manhole cross-sectional view.
More than among each figure: 1. well lid, 2. manhole goes out the well casing borehole wall, 3. cat ladder, 4. the manhole borehole wall, 5. drainage pipe interface, 6. shaft bottom.
The specific embodiment
Shown in the accompanying drawing, the manhole borehole wall 4 is cylindrical, has 2 drainage pipe interfaces 5, the porous well that crosses on the cylindrical manhole borehole wall 4 at least, press actual needs reserved drainpipe pipeline joint 5, the cylindrical manhole borehole wall 4 bottoms are shaft bottoms 6, open well, and shaft bottom 6 and drainage pipe interface 5 are on same horizontal plane, deposition into wells, shaft bottom 6 is lower than drainage pipe interface 5, makes deposit in low 6 precipitations of well, by manhole cleaning deposit.The cylindrical manhole borehole wall 4 tops are connected to cylindrical manhole and go out the well casing borehole wall 2, the cylindrical manhole borehole wall 4 goes out the well casing borehole wall 2 with cylindrical manhole and is prefabricated into one, cylindrical manhole goes out the well casing borehole wall 2 tops the well head of going out well lid 1, goes out the well casing borehole wall 2, the manhole borehole wall 4 to being installed with cat ladder 3 shaft bottom from going out well head to the lower edge manhole.This sewage manhole material adopts PE or glass fiber reinforced plastic to make.
