Abstract
The utility model discloses a load-bearing and pressure-bearing combination type inspection shaft. The inspection shaft comprises a sectional shaft formed by combing four circular arc modules (4) in uniform shapes and sizes; each circular arc module (4) is provided with at least a reinforcing rib (3); bolted connection sides (2) connected with adjacent circular arc modules (4) are arranged on axial lateral sides of each circular arc module (4); at least a pipe mouth opening (6) is formed on each circular arc module (4); and matched inserting holes are formed at the radial top and the radial bottom of each circular arc module (4). The inspection shaft disclosed by the utility model effectively bears loads and pressure, prevents leakage, and is practical and safe.
Description
Technical field
The utility model discloses a kind of load-bearing pressure-bearing combined inspection shaft tube that utilizes high molecular material resin base and other material produced with combination, belong to building environmental protection field.
Background technology
At present, in the manhole of pipe-networks engineerings such as civilian construction and municipal engineering, uptown, tap water, telecommunications, electric power greatly to there being three kinds: first kind is brick mix structure; Second kind is reinforced concrete prefabricated; The third is the composite material synthesis type manhole of enabling in recent years.
First kind: brick mix structure is because of the multinomial transhipment of material and the limitation of some construction plants, and cause constructing very complicated and construction period are long; Simultaneously because the defective of material itself, this product not only appearance is coarse but also seepage is serious, and also very unstable the causing when carrying out constructing the second time easily of structure collapsed.
Second kind: reinforced concrete prefabricated this causes transhipment gruelling to a certain extent because of individual heavy, and cost of transportation is also very high simultaneously.The problem that this prefabricated component does not also have thoroughly to solve seepage and permeated, another this product need thoroughly to change in case be damaged when construction and be difficult for repairing.
The third: is though other composite material synthesis type is checked the problems such as seepage of the fine roughening that solves brick mix structure of pit shaft, concrete precast element, but owing to ignore the complexity of its construction and the polytropy of geological conditions, often intensity and stiffness are all very poor, and transportation the squeeze crack phenomenon occurs in installing easily.
The utility model content
Technical problem to be solved in the utility model provides the load-bearing pressure-bearing combined inspection shaft tube of a kind of effective load-bearing pressure-bearing and anti-leakage, practical safety.
In order to solve the problems of the technologies described above, the load-bearing pressure-bearing combined inspection shaft tube that the utility model provides, comprise the assistant warden pit shaft, circular arc module combinations block-shaped and of the same size forms described assistant warden pit shaft by four, every described circular arc module is provided with at least one reinforcing rib, the axial side of described circular arc module is provided with the bolt fillet that is connected with adjacent circular arc module, on described circular arc module, be provided with a mouth of pipe hole at least, the radial top of described circular arc module and radially the bottom be provided with the cooperation interface.
Described mouth of pipe hole is located on the bolt fillet on the described circular arc module.
Described reinforcing rib is one and is arranged on the axial middle part of described circular arc module.
Described reinforcing rib is made by the reinforcing bar of 25mm.
The radial top of described circular arc module is provided with concave ring groove, and the radially bottom of described circular arc module is provided with and the bulge loop of described groove fit to inserting.
Adopt the load-bearing pressure-bearing combined inspection shaft tube of technique scheme, made reinforcing rib, a plurality of assistant warden pit shafts are formed by pegging graft, be convenient to install, economical with materials and man-hour, thus save cost, be assembled into multistage inspection pit shaft by multimode, not only well solved seepage and by infiltration problem, and inner exquisite smooth, can the load-bearing pressure-bearing, convenient transportation, quick for installation be the inevitable substitute of current pipe-networks engineering manhole.
The utility model reaches following effect:
One, overall structure good airproof performance, leakproof and infiltration have solved thoroughly that brick mix structure and reinforced concrete precast member are coarse, seepage and the problem of being permeated.
Two, changed the synthetic problem of checking the anti-extrusion and load-bearing of pit shaft of other composite material.
Three, convenient fortune connect, quick for installation, reduced transport power and construction cost.
Four, safeguard and overhaul very conveniently, effectively reduce cost of production and construction cost.
In sum, the utility model is the load-bearing pressure-bearing combined inspection shaft tube of a kind of effective load-bearing weight and anti-leakage, practical safety.
