Description

Manhole well bore building block

Technical field

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

Background technology

The webmaster manhole mostly 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 larger increase the difficulty of construction and can't guaranteeing of workmanship;

Secondly, intensity is low, and the support strength of brickwork construction is low, especially easily subsides because the horizontal active force of imbalance impacts near the brickwork construction reducing reducing part on road surface; Secondly well body construction cycle long, construction is complicated, and is high to the civil engineering requirement owing to must piling up at manual scene, standardization, generalization, seriation degree are poor, by hand and materials how much be the key factor that affects quality; Exist in addition and can not change, easily break and seepage and the defective such as pollute, need frequently maintenance.

Again; the ladder great majority that need to check pile up fixedly by brick concrete pit well bore that reinforcing bar forms, and ladder is become flexible, and understand 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 in the utility model provides that a kind of generalization is high, easy construction, good airproof performance, antioxidant anticorrosive performance are good, be convenient to adjust the manhole well bore building block well bore height and that improve work safety, the defects that exists to overcome existing inspection shaft.

The technical scheme of the utility model technical solution problem is as follows: manhole well bore building block is formed by integrated injection molding, and it comprises main part and step.

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

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

Its use is as follows: the upper port of a manhole well bore building block is docked with the upper 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 be engaged, 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 be engaged, 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, the beneficial effects of the utility model are: can decide according to the height of construction requirement the number of assembling manhole well bore building block, thereby solve because of the out of use problem of differing heights; Strengthen protuberance towards the structure in the sphere sidewall outside by the first convex surface of strengthening 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; Manhole well bore building block is formed by integrated injection molding, and generalization is improved, easy construction, good airproof performance, antioxidant anticorrosive performance are good.
