Abstract
The invention relates to a well seat of a spiral steel belt inspection well. The well seat should have the advantages of convenience in construction, simple structure and high strength, so that deformation and damage in the process of construction and use are reduced. The technical scheme includes that the well seat comprises a seat body, a wellhole joint and at least two pipeline joints which are integrally formed through injection molding, the wellhole joint is arranged in a vertically upward manner, the pipeline joints extend towards the side face of the seat body, and an external thread used for connecting a pipeline is formed on the outer wall of each pipeline joint. The well seat is characterized in that each external thread is formed by a flange spirally extending along the outer wall of the corresponding pipeline joint, and each flange is embedded in a metal belt used for improving strength.
Description
Technical field
The present invention relates to manhole technical field, be specifically related to the well seat of helical steel band manhole.
Background technology
Plastic inspection well is commonly called as plastics " inspection shaft ", is generally located on drainage pipe intersection, turning, caliber or gradient change place, drop place and straight line pipeline section and locates at a certain distance, be convenient to make regular check on, the drainage structures of clean and dredging pipeline.Plastic inspection well, take macromolecule resin as raw material, adopts combining structure, is conventionally made up of well seat, pit shaft, well lid, cage and concrete support plate etc.; Wherein crucial well seat part adopts once injection moulding, reaches the connection that changes caliber and angle with accessories such as reducer union, variable angle joint and sealing rings.Pavement loading acts on around manhole by well lid, well seat, avoided the destruction of pavement loading to manhole, cage has the function fluctuating, and the height that can initiatively adapt to road surface changes, pit shaft can intercept respective length according to the on-the-spot depth of burying simultaneously, has very large flexibility.
Above-mentioned well seat (is vertically arranged upward) except being shaped with a pit shaft joint being connected with pit shaft; conventionally be also shaped with 2～4 pipe joints of extending towards side; pipe joint by coupling (as pipe collar, pipeline leakage plugging device etc.) with enter (going out) water pipe and be tightly connected; convenient and quick construction; but the pipe joint intensity of existing well seat is not high; in construction or use procedure, easily distortion and even damaged, affects the normal use of manhole, waits to improve.
Summary of the invention
For the deficiency in above-mentioned background technology, the invention provides the well seat of helical steel band manhole, this well seat should have easy construction, the feature that simple in structure, intensity is high, thereby reduces distortion and damaged situation in construction and use procedure.
The technical solution adopted in the present invention is: the well seat of helical steel band manhole, comprise pedestal, pit shaft joint and at least two pipe joints of integrated injection molding, pit shaft joint is arranged straight up, pipe joint is stretched towards the side of pedestal, the outer wall of each pipe joint is shaped with the external screw thread for connecting pipe, it is characterized in that: the fin that described external screw thread is stretched by an outer wall spiral along pipe joint forms, and fin is embedded in and is useful on the metal tape of gaining in strength.
The cross section of the metal tape in described fin is arch, the both sides of metal tape are shaped with and are shaped with respectively flanging, the flanging of both sides all embeds in the tube wall of pipe joint, the outer wall of metal tape and inwall are injected with respectively outer plastic layer and inner plastic layer, and between inner plastic layer and the tube wall of pipe joint, be hollow structure, the both sides of outer plastic layer and inner plastic layer are all injection molded into one with the tube wall of pipe joint.
Described metal tape is steel band.
The quantity of described pipe joint is two, and the axis coaxle of two pipe joints is arranged or be mutually vertical.
The quantity of described pipe joint is three, and wherein the axis coaxle of two pipe joints is arranged, and vertical with the axis of another pipe joint.
The quantity of described pipe joint is four, and four pipe joints are cross arranges, the wherein axis coaxle of two pipe joints, and the axis of the pipe joint coaxially arranged with two other is vertical.
The invention has the beneficial effects as follows: in the external screw thread in the present invention, embed and have metal tape, thereby can increase the intensity of pipe joint, can bear larger external force, reduce distortion and damaged situation, and external screw thread in the present invention is hollow structure, weight is alleviated, and reduces raw-material use, reduce cost of production, in addition, the present invention is simple in structure, easy to manufacture, construct also very convenient, there are good market prospects.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 be in Fig. 1 A-A to analyse and observe enlarged diagram.
The specific embodiment
Below in conjunction with Figure of description, the invention will be further described, but the present invention is not limited to following examples.
