Abstract
The present invention relates to the well seat of helical steel band inspection shaft. The well seat that object is to provide should have easy construction, the feature that simple in structure, intensity is high, thereby reduces distortion and damaged situation in construction and use procedure. Technical scheme is: the well seat of helical steel band inspection shaft, 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.
Description
Technical field
The present invention relates to inspection shaft technical field, be specifically related to the well seat of helical steel band inspection shaft.
Background technology
Plastic inspection well is commonly called as plastics " inspection shaft ", is generally located at drainage pipeline intersection, turning, caliberOr locate at a certain distance on gradient change place, drop place and straight line pipeline section, be to be convenient to make regular check on, clearlyThe drainage structures of clean and dredging pipeline. Plastic inspection well, taking macromolecule resin as raw material, adopts combining structure,Conventionally formed by well seat, pit shaft, well lid, cage and concrete support plate etc.; Wherein crucial well seat partAdopt once injection moulding, reach and change pipe with accessories such as reducer union, variable angle joint and sealing ringsThe connection of footpath and angle. Pavement loading acts on around inspection shaft by well lid, well seat, has avoided road surface to carryThe destruction of lotus to inspection shaft, cage has the function fluctuating, and the height that can initiatively adapt to road surface changes,Pit shaft can intercept corresponding 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, commonAlso be shaped with 2～4 pipe joints of extending towards side, pipe joint is passed through coupling (as pipe collar, KazakhstanHusband joint etc.) with enter (going out) water pipe and be tightly connected, convenient and quick construction, but the pipe joint of existing well seatIntensity is not high, and in construction or use procedure, easily distortion and even damaged, affects the normal use of inspection shaft,Wait to improve.
Summary of the invention
For the deficiency in above-mentioned background technology, the invention provides the well seat of helical steel band inspection shaft, this wellSeat should have easy construction, the feature that simple in structure, intensity is high, thereby reduces in construction and use procedureDistortion and damaged situation.
The technical solution adopted in the present invention is: the well seat of helical steel band inspection shaft, comprises integrated injection moldingPedestal, pit shaft joint and at least two pipe joints, pit shaft joint is arranged straight up, pipe jointStretch side towards pedestal, and the outer wall of each pipe joint is shaped with the external screw thread for connecting pipe, its spyLevy and be: the fin that described external screw thread is stretched by an outer wall spiral along pipe joint forms, in finEmbedding is useful on the metal tape of gaining in strength.
The cross section of the metal tape in described fin is arch, and 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, and the outer wall of metal tape and inwall are injected with respectively outer mouldingThe bed of material and inner plastic layer, and be hollow structure between inner plastic layer and the tube wall of pipe joint, outer plastic layerAll be injection molded into one with the tube wall of pipe joint with the both sides of inner plastic layer.
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, wherein the axis coaxle of two pipe joints arrange, and with separatelyThe axis of a pipe joint is vertical.
The quantity of described pipe joint is four, and four pipe joints are cross arranges, wherein two pipelinesThe axis coaxle of joint, 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 increaseThe intensity of pipe joint, can bear larger external force, reduces distortion and damaged situation, and thisExternal screw thread in bright is hollow structure, and weight is alleviated, and reduces raw-material use, has reduced and has been produced intoThis, in addition, the present invention is simple in structure, easy to manufacture, constructs also very convenient, has good market prospects.
Brief description of the drawings
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.
Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described, but that the present invention is not limited to is followingEmbodiment.
As shown in Figure 1, the well seat of helical steel band inspection shaft of the present invention, comprises integrated injection moldingPedestal 4, pit shaft joint 3 and at least two pipe joints, pit shaft joint is arranged straight up, pipe jointStretch side towards pedestal, and the outer wall of each pipe joint is shaped with the external screw thread for connecting pipe. As Fig. 2Shown in, the fin 2 that described external screw thread is stretched by an outer wall spiral along pipe joint forms, in finEmbedding is useful on the metal tape 6 of gaining in strength, recommend adoption steel band.
The cross section of the metal tape in described fin be arch (can be also other shape, for example semicircle,Determine as required), maximum height is 3～6cm, Breadth Maximum is 6～8cm, also can connect according to pipelineHead actual size determine, the both sides of metal tape are shaped with and are shaped with respectively flanging 6-1, the flanging of both sides is equalEmbed in the tube wall 1 of pipe joint, the outer wall of metal tape and inwall be injected with respectively outer plastic layer 5-1 andInner plastic layer 5-2(outer plastic layer, inner plastic layer are identical with the tube wall material of pipe joint). Inner plastic layer withThereby between the tube wall of pipe joint, be hollow structure weight reduction, the both sides of outer plastic layer and inner plastic layer are equalBe injection molded into one with the tube wall of pipe joint.
The recommendation thickness of described outer plastic layer and inner plastic layer is: outer plastic layer 1.5～3mm, inner plastic0.1～0.5mm, also can determine according to the actual size of pipe joint.
The quantity of described pipe joint is definite as required, is generally 2～4, and each pipe joint each otherCan arrange by coaxial line, or be mutually arranged vertically, or be mutually a fixed inclination (such as 30 °, 120°, 270 °). Below illustrate: the quantity of (1) described pipe joint is two two pipe jointsAxis coaxle arrange or mutually vertical; (2) quantity of described pipe joint is three, wherein two pipesThe axis coaxle layout of road joint, and vertical with the axis of another pipe joint; (3) described pipe jointQuantity be four, 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.
