Description

The fan-shaped drainage inspection well of plastics municipal administration

Technical field

A kind of fan-shaped drainage inspection well of plastics municipal administration is the utility model is related to, belongs to drainage system field, more particularly to should The inspection shaft at large-caliber drainage pipeline turning under town road.

Background technology

Municipal drainage is divided into rainwater and sewage, and run-off system is divided into two kinds of separate system and combined system, and most of city is all Separate system is taken, i.e. rainwater, sewage discharges respectively.Unit or residential area along urban road are typically all functional in organized water drainage, Rainwater, sewage are collected to the drainage pipeline drained under urban road, are commonly called as municipal drain.Rainwater, sewage are arranged by municipal administration again Waterpipe drains into water body or sewage treatment plant.Municipal drainage pipeline at spacing intervals, pipeline turning, need at branch pipe access Inspection shaft is set.The characteristics of municipal drain is that caliber is larger, and the inspection shaft used is also larger.《Code for design of outdoor sewerage engineering》 GB50014-2006, regulation is all made that to the well room height of inspection shaft, the setting of chute, turning inspection shaft chute radius. When carrying out drainage pipeline design, designer is to use national standard drawing《Drainage inspection well》02S515, or《Municipal administration row Waterpipe engineering and affiliated facility》06MS201, the latter are the former revision file versions.Municipal drainage inspection shaft is according to caliber Difference is divided into circle, rectangle, sector etc..Circular inspection well is only applicable to the pipeline that caliber is less than 1000mm, turns in drainage pipeline Crook, pipeline of the caliber more than or equal to 1000mm typically all use fan-shaped well.

The chute of fan-shaped well is curvilinear, existing standard drawing inspection shaft, is divided to brick and two kinds of structure shapes of concreting Formula.Most of in Practical Project is to use brickwork construction, brick to have easy construction, short time limit etc. relative to concrete structure Advantage.But building by laying bricks or stones for brick drainage inspection well requires very high, and puzzle joint mortar should be full, and well inner waterproofing sand finish is closely knit. Closed-water test is carried out before drainage pipeline backfill, examines the airtight performance of pipeline.Closed-water test requires that band well is tested, i.e., pipeline connects With inspection shaft together closed-water test.Inspection shaft in practice of construction being often present, to build brickwork joint by laying bricks or stones not tight, especially pipeline and inspection Look into it is more difficult between well build by laying bricks or stones, the hidden danger of quality such as leakiness of being wiped one's face in well.Height of being wiped one's face in standard drawing rainwater inspection well is in pipe 200mm on top, height of wiping one's face in sewage inspection well to well ceiling, the water level of closed-water test are the inspection well casing of test section most upstream Interior top above 2m, it is possible to the phenomenon that water level is higher than height of wiping one's face be present, inspection shaft easily causes leak especially cover plate It is main portions that leak occur with the seat of well body slurry, it is not reach requirement, it is necessary to wipe one's face again very that leak, which causes closed-water test, Built by laying bricks or stones again to inspection shaft is removed.Drainage also occurs in the inspection shaft of concrete cast in situs leakiness of vibrating.Therefore, if Meter personnel typically can be when applying mechanically standard drawing, it is desirable to wipes one's face in rainwater inspection well to well head, is wiped one's face inside and outside sewage inspection well to well Mouthful.The chute of fan-shaped well is curvilinear, and brick and concrete inspection well technological requirement is high, and difficulty of construction is big, and site operation is by people Member's technical merit influences greatly, and construction quality is uneven, long construction period, and airtight performance is not so good as plastic inspection well.Due to big mouth The fan-shaped well size of footpath drainage pipeline is larger, and plastic inspection well bearing capacity is limited, and prior art is more than for caliber etc. In 1000mm plastics sector drainage inspection well.

The content of the invention

The purpose of this utility model is：There is provided a kind of plastics municipal administration fan-shaped drainage inspection well, be more than or equal to for caliber At 1000mm drainage system pipeline turning.Using the construction size of current standard figure inspection shaft as foundation, meet specification chute, Workbench and maintenance requirement of going into the well.Mainly it is made up of plastics well body and reinforced concrete frame, plastics well body includes well seat, well Body, bed die, pit shaft using plastic production into component, these plastic member assembled in situ form, and are around plastics well body Basis, well room post, cover plate, pit shaft post, walling crib composition cast-in-situ steel reinforced concrete framework, composition one by plastic member assemble and Into waterproof plastic well body, steel bar framework mixes structure inspection well for the modeling of load-carrying members.Soil pressure around ground load and well Undertaken by armored concrete, this mixed structure of modeling has the good seal of plastics, the stronger bearing capacity of armored concrete.Framework Concreting makees template using plastics well body, without formwork and form removal, saves the material of formwork form removal and artificial.Beneficial to effect Fruit is：Solve the problems, such as the low inadaptable making heavy caliber drain pipe sector inspection shaft of plastic strength, compensate for prior art Brick or concrete inspection well seal is poor, drainage easily occurs, working procedure is complicated, the weakness of long construction period.
