The utility model relates to an underground water and sewage drainage well which is used in municipal works and an inspection well support of a cable pipe network, particularly a plastic inspection well, which comprises a well cover, a well cover support, a well body and a well seat which are arranged in an order from top to bottom, wherein the well cover is covered on the well body through the well cover support which is fixedly installed at the upper end of the well body. The well body of which both ends are opened is in a tubular structure. A lower end opening of the well body is fixedly connected with the well seat. The side wall of the well body is provided with at least 2 external connecting bores. The inspection well is inside provided with a connecting pipeline which makes the external connecting bores connected with each other. A sealing ring is arranged between the connecting pipeline and the external connecting bores. The utility model has the advantages of high generalization, easy construction, good sealing performance, good anti-oxidation and anti-corrosion performance, long lifetime, etc.

Description

Plastic inspection well

Technical field

The utility model relates to a kind of municipal engineering and props up with the manhole of underground draining, blowdown inspection shaft and cable pipe network.

Background technology

Existing municipal engineering mostly are brick concrete inspection shaft with underground pipe network inspection shaft, mainly there is following shortcoming in it: at first intensity is low, the support strength of brickwork construction is low, especially impacts because of influence of unbalance power near the brickwork construction reducing reducing part on road surface and easily subsides; Secondly well body construction cycle long, construction is complicated, owing to must pile up at manual scene, civil engineering is required height, standardization, generalization, seriation degree are poor, by hand and materials how much be the key factor that influences quality; Exist in addition and can not change, easily break and seepage and defective such as pollute, need frequently maintenance.

Summary of the invention

Technical problem to be solved in the utility model provides that a kind of generalization height, easy construction, good airproof performance, antioxidant anticorrosive performance are good, the plastic inspection well of long service life, to overcome the above-mentioned defective that existing inspection shaft exists.

The technical scheme of the utility model technical solution problem is as follows:

A kind of plastic inspection well, it is characterized in that, comprise from top to bottom that the well lid, the well lid that are provided with in turn prop up, well bore and base, described well lid props up by the well lid that is fixedly installed on the well bore upper end and covers on well bore, described well bore is the tubular structure of both ends open, and the lower port of described well bore is fixedlyed connected with base, and the sidewall of described well bore is provided with at least 2 external holes, being provided with connecting pipe in the described inspection shaft will couple together between the described external hole, is provided with sealing ring between described connecting pipe and the external hole.

Also comprise be fixedly installed on that well lid props up and well bore between preliminary shaft, described preliminary shaft is the reducing of the reducing from bottom to up preliminary shaft of both ends open, the lower port of described preliminary shaft is fixedlyed connected with the upper port of well bore, upper port is propped up fixedly with well lid and is connected.

Described connecting pipe is divided into two perfectly straight types, two logical curved, triplet type or four-way types.

Described preliminary shaft and well bore outer wall are provided with the reinforcement convex tendon that is provided with at interval.Convex tendon is in order to the intensity of the whole inspection shaft of further enhancing.

Described well bore and base are square structure, and described inspection shaft integral body is approximate cuboid.

Described well lid prop up with preliminary shaft between, can be connected or bond by Plastic Welding between preliminary shaft and well bore, well bore and the base by cementing agent.

The borehole wall of described well bore is by being arranged on the tenon socket connection at oblique angle, four flat panel ends.

By above disclosed technical scheme as can be known, the utlity model has following advantage:

(1), intensity height: the utility model adopts polymer composite tubing, its intensity and steel are suitable, impact strength is big, and because preliminary shaft is an integrated structure, avoided that traditional inspection shaft exists especially in impacting defective such as easily subside because of influence of unbalance power near the brickwork construction reducing reducing part on road surface.

(2), long service life: whole inspection shaft bonds by Plastic Welding, and well body good airproof performance is difficult for breaking and seepage, and acid-alkali-corrosive-resisting.

(3), generalization height: can adopt the standardization professional production in the factory, the various piece of well body has versatility, can produce the inspection shaft of various different sizes as required, props up needs to satisfy different wells.And installation and efficiency of construction height.

(4), convenient maintenance and replacement.

The specific embodiment

Further specify the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, the utility model plastic inspection well, comprise from top to bottom that the well lid 1, the well lid that are provided with in turn prop up 2, well bore 3 and base 4, described well lid 1 props up 2 by the well lid that is fixedly installed on well bore 3 upper ends and covers on well bore 3, described well bore 3 is the tubular structure of both ends open, the lower port of described well bore 3 is fixedlyed connected with base 4, the sidewall of described well bore 3 is provided with at least 2 external holes 301, be provided with connecting pipe 5 in the described inspection shaft with coupling together between the described external hole 301, be provided with sealing ring 6 between described connecting pipe 5 and the external hole 301.

Also comprise be fixedly installed on well lid prop up 2 and well bore 3 between preliminary shaft 7, the reducing of the reducing from bottom to up preliminary shaft that described preliminary shaft 7 is a both ends open, the lower port of described preliminary shaft 7 is fixedlyed connected with the upper port of well bore 3, the upper port of preliminary shaft 7 is propped up 2 with well lid and is fixedlyed connected.

Described connecting pipe 301 can be two perfectly straight types, two logical curved (shown in Figure 4), triplet type or four-way types (as shown in Figure 2).

Described preliminary shaft 7 and well bore 3 outer walls are provided with the reinforcement convex tendon 8 that is provided with at interval.

Described well bore 3 and base 4 are square structure, and described inspection shaft integral body is approximate cuboid.Described inspection shaft also can be cylindric and other gengons.
