Description

Manhole well bore building block

Technical field

The present invention relates to a kind of municipal engineering with underground draining, blowdown manhole building block, particularly a kind of generalization height, easy construction, good airproof performance, the manhole well bore building block that the antioxidant anticorrosive performance is good, easy to use.

Background technology

Mostly the webmaster manhole is brick concrete inspection well under the existing municipal engineering land used, and mainly there is following shortcoming in it:

At first, height can't arbitrarily be changed, and the user is only using fixing height, thus bigger increase the difficulty of construction and can't guaranteeing of workmanship;

Secondly, intensity is low, and the support strength of brickwork construction is low, and especially the brickwork construction reducing reducing part near the road surface is prone to subside because of the horizontal active force of imbalance impacts; 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, be prone to break and seepage and defective such as pollute, need frequently maintenance.

Once more; Reinforcing bar forms to need the ladder great majority of inspection to pile up fixedly by brick concrete inspection shaft well bore, and ladder is become flexible, and understands crisis procurator's personal safety; Then carry the ladder inspection of going into the well by the inspection personnel, cause workload to increase.

Summary of the invention

Technical problem to be solved by this invention provide a kind of generalization height, easy construction, good airproof performance, antioxidant anticorrosive performance good, be convenient to adjust the manhole well bore building block well bore height and that improve work safety, to overcome the above-mentioned defective that existing inspection shaft exists.

The technical scheme of technical solution problem of the present invention is following: manhole well bore building block is formed by the one injection moulding, and it comprises main part and step.

Aforementioned body portion comprises port, lower port and sphere sidewall; The port setting holds projection and holds groove, and holding projection is that arrange the space with holding groove; The sphere sidewall is provided with first and strengthens protuberance, second reinforcement protuberance and the ribs; First strengthens protuberance is arranged at sphere sidewall inwall; And the convex surface of the first reinforcement protuberance is provided with towards the sphere interior; It comprises sector and reduces arcwall face, and sector is concordant with the lower surface, reduces arcwall face towards to upper surface extension and at the rounding off to the upper end surface not; Second strengthens protuberance is arranged at sphere sidewall outer wall, and second strengthen protuberance convex surface towards sphere sidewall outer setting, second strengthens protuberance is provided with along the sphere sidewall from the direction of port to lower port; Ribs is arranged at the sector place in the first reinforcement protuberance outside, and extends towards port along the concave surface of the first reinforcement protuberance, and lower port is provided with butt joint projection and docking recess.

Above-mentioned step is arranged at sphere sidewall inner surface wall and concordant with the port end face, and it comprises and is at least two U shape bodies and is combined to form side by side.

It uses as follows: the port of a manhole well bore building block is docked with the port of another manhole well bore building block; Wherein a manhole well bore building block hold projection and another manhole well bore building block hold that groove is supporting to engage; And then again will be wherein a manhole well bore building block hold groove and another manhole well bore building block hold that projection is supporting to engage; Thereby above-mentioned two manhole well bore building blocks are combined; Again the lower port of the 3rd manhole well bore building block is docked with the lower port of an above-mentioned manhole well bore building block; Decide the number of assembling manhole well bore building block according to the height of construction requirement, thereby solve because of the out of use problem of differing heights.

Compared with prior art, beneficial effect of the present invention is: can decide the number of assembling manhole well bore building block according to the height of construction requirement, thereby solve because of the out of use problem of differing heights; Strengthen the structure of protuberance through the convex surface of the first reinforcement protuberance towards sphere inside sidewalls and second simultaneously, strengthened the support strength of manhole well bore building block, thereby prolonged the application life of manhole well bore building block towards the sphere outside; Manhole well bore building block is formed by the one injection moulding, and generalization is improved, easy construction, good airproof performance, antioxidant anticorrosive performance are good.
