Abstract
The utility model discloses a kind of high strength steel and mould manhole, comprise well seat and by-pass connection, by-pass connection is connected on well seat, well seat comprises outer tube and interior pipe, many the steel bands axially arranged circumferentially evenly are provided with between outer tube and interior pipe, be evenly distributed with steel loop by corrugated vertically between outer tube and steel band, the cross section of steel loop is arc-shaped.This high strength steel is moulded manhole and is improved manhole well seat surface to the resistance of impacting, and improves the transverse strength of manhole well seat, can prevent manhole well seat transverse breakage, the intensity of this manhole of General Promotion, extends the application life of manhole further.
Description
Technical field
The utility model relates to manhole field, particularly relates to a kind of high strength steel bearing larger pressure and impact force and moulds manhole.
Background technology
Manhole is generally located at that drainage pipe intersection, turning, caliber or the gradient change, drop place and straight line pipeline section are located at a certain distance, be convenient to make regular check on, the draining ancillary structure of clean and dredging pipeline.Plastic inspection well is widely used at the place such as power system, communication system, existing plastic inspection well, comprise well seat and by-pass connection, by-pass connection is connected on well seat, plastic inspection well weight capacity is more weak, carry certain weight just easily to flatten, run into certain vibrations or impact force is just easily broken.
Utility model content
For solving the problems of the technologies described above, the utility model devises a kind of high strength steel bearing larger pressure and impact force and moulds manhole.
The utility model adopts following technical scheme:
A kind of high strength steel moulds manhole, comprise well seat and by-pass connection, by-pass connection is connected on well seat, well seat comprises outer tube and interior pipe, many the steel bands axially arranged circumferentially evenly are provided with between outer tube and interior pipe, be evenly distributed with steel loop by corrugated vertically between outer tube and steel band, the cross section of steel loop is arc-shaped.
As preferably, be socketed with PE corrugated ring outside described steel loop, PE corrugated ring is fixedly connected with steel band respectively with outer tube, steel loop, and steel loop is fixedly connected with steel band, and steel band is fixedly connected with interior pipe.
As preferably, described PE corrugated ring and steel band and steel loop bond fixing respectively by binding resin.
As preferably, the external surface of described well seat is fixedly installed circular ribs.
As preferably, described well seat and by-pass connection are structure as a whole.
Compared with prior art, this high strength steel is moulded between manhole outer tube and interior pipe and is circumferentially evenly provided with many steel bands axially arranged, steel loop is evenly distributed with by corrugated vertically between outer tube and steel band, the cross section of steel loop is arc-shaped, the design of the steel loop distributed by steel band and corrugated strengthens the intensity of this manhole well seat greatly, stressed between inner and outer tubes can carry out flexible buffering by undulatory steel loop, improve manhole well seat surface to the resistance of impacting, steel band promotes the transverse strength of manhole well seat, manhole well seat transverse breakage can be prevented, the intensity of this manhole of General Promotion, the application life of further prolongation manhole, the external surface of well seat is fixedly installed circular ribs, promote the supporting capacity of manhole.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
In figure: 1, well seat, 2, by-pass connection, 3, outer tube, 4, interior pipe, 5, steel band, 6, steel loop, 7, PE corrugated ring, 8, ribs.
Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figure 1, a kind of high strength steel moulds manhole, comprise well seat 1 and by-pass connection 2, by-pass connection is connected on well seat, well seat comprises outer tube 3 and interior pipe 4, eight steel bands 5 axially arranged circumferentially evenly are provided with between outer tube and interior pipe, steel loop 6 is evenly distributed with by corrugated vertically between outer tube and steel band, the cross section of steel loop is arc-shaped, PE corrugated ring 7 is socketed with outside steel loop, PE corrugated ring and outer tube, steel loop is fixedly connected with respectively with steel band, steel loop is fixedly connected with steel band, steel band is fixedly connected with interior pipe, PE corrugated ring and steel band and steel loop bond fixing respectively by binding resin, the external surface of well seat is fixedly installed circular ribs 8, well seat and by-pass connection are structure as a whole.
This high strength steel is moulded between manhole outer tube and interior pipe and is circumferentially evenly provided with eight steel bands axially arranged, steel loop is evenly distributed with by corrugated vertically between outer tube and steel band, the cross section of steel loop is arc-shaped, the design of the steel loop distributed by steel band and corrugated strengthens the intensity of this manhole well seat greatly, stressed between inner and outer tubes can carry out flexible buffering by undulatory steel loop, improve manhole well seat surface to the resistance of impacting, steel band promotes the transverse strength of manhole well seat, manhole well seat transverse breakage can be prevented, the intensity of this manhole of General Promotion, the application life of further prolongation manhole, the external surface of well seat is fixedly installed circular ribs, promote the supporting capacity of manhole.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
