Abstract

The utility model relates to an assembly box type inspection well for pipeline in lightweight composite material, which is characterized in that the well is constructed by detachably splicing a seat, a front and a rear side panel in the same, a left and a right side panel in the same. The assembly box type inspection well for pipeline in lightweight composite material facilitates human operation, no affection to the environment is caused because no clay bricks is used, no sand, rocks and cement is used for the masonry, and is an environment friendly pipeline inspection well. The utility model proposes that the inspection well is subject to product production in prefabrication form, then spliced and connected in the field, and in field masonry is eliminated. Not only no affection to the operation field is caused, but also the installation is easy, the splicing speed is high, the construction speed is enhanced by more than 3 times, and the construction cost is lowered by 50% because composite material is used for the seat, the front, the rear, the left and the right side panels. The efficiency is high, and the entire strength of the inspection well is also high.

Description

Assembling box light composite material pipe manhole

Technical field

The utility model relates to a kind of manhole of pipeline, specifically be a kind of little to the operation field ambient influnence, assembly unit speed is fast, and efficient height, pipe manhole that bulk strength is high.

Background technology

With people's life, the many closely pipe-line inspections of working relation, to guarantee safety with needing not timing; Especially some municipal engineering, for example thermoelectricity, communication, coal gas, fire-fighting etc.Pipe inspection need be built a manhole at operation field, traditional pipe manhole, often adopt clay common brick or cement sanded brick and masonry of cement mortar to form, because the main material of masonry is solid clay common brick, and solid clay common brick occupies cultivated land in a large number because of its production, destroy the soil, consumes energy, contaminated environment is a kind of nondegradable resource-hungry product, is limited the quantity of in the city by a lot of local governments even bans use of; Adopt the cement sanded brick, because the structure of building by laying bricks or stones is soaked through rainwater underground, external force (as heavy vehicle) repeat function is easy to plaster and comes off, and is loosely organized, and whole well body is destroyed; Pipe manhole is built at the scene by laying bricks or stones, and sand, stone, cement and brick be manageability not at the scene, have greater environmental impacts, and it is low manually to build work efficiency by laying bricks or stones, and expense is big, and is very uneconomical.

The utility model content

The purpose of this utility model provide a kind of little to the operation field ambient influnence, assembly unit speed is fast, and efficient height, pipe manhole that bulk strength is high.

The purpose of this utility model can realize by following technical scheme: a kind of assembling box light composite material pipe manhole is characterized in that: it is made of base, identical forward and backward side plate and identical left and right side plate assembly unit removably.

The end face periphery of described base has four grooves all around, and each groove joins in twos and constitutes closed square, and the length of each groove is corresponding with the front, rear, left and right side plate respectively with thickness; Described front, rear, left and right side plate vertically is inserted on the described base top surface groove, and described front, rear, left and right side plate vertically splicing place design has corresponding connected structure; Side plate vertical dual-side in described front, rear, left and right has the through hole or the screwed hole of a pair of correspondence at least, and the steel card and the connector that all have " L " type of connecting hole by two right-angle sides connect adjacent biside plate.

The connected structure of described front, rear, left and right side plate is: the two ends in the cross section of each vertical front, rear, left and right side plate are the corresponding stairstepping groove and tognue type that overlaps that an angle bar is made.

On the basis of the above, the utility model can be done following improvement:

The bottom of described base is provided with one deck reinforced mesh, and the size and the base of this reinforced mesh adapt.

Be provided with one deck reinforced mesh at least in the side plate of described front, rear, left and right in any side plate more than one or, the size of described reinforcing bar steel disc and each side plate adapt.

The end face of described base is located at suspension ring; Reinforced mesh in these suspension ring and the described base extension that interlocks.Use other these suspension ring of corollary equipment lifting to move this base up and down.

The center of described base has the through hole that penetrates, and this through hole is as sump.

Described forward and backward side plate all has the preformed hole that is used for by communication conduit, and the preformed hole on the biside plate is located at the position of symmetry.

The material of described composition manhole side plate, end plate, base adopts composite material.

Compared with prior art, the utility model manual work of being more convenient for simultaneously because of not using loam brick, influences environment hardly without sand, stone, cement masonry, is a kind of environment-friendly type pipe manhole.The utility model proposes and take prefabricated form to carry out commercialization production manhole, behind the scene, carry out the assembly unit connection then, build by laying bricks or stones at the cancellation scene, not only the operation field environment there is not influence, and, install lightly because base, front, rear, left and right side plate use is composite material, assembly unit speed is fast, speed of application improves more than three times, and operating expenses reduces by 50%; The efficient height, the manhole bulk strength is also high.
