Abstract
The invention discloses a tube with pedal and relative application in the check well. Wherein, the inner wall of tube is mounted with pedals whose surface are mounted with anti-slide protrude blocks; two sides of pedal are mounted with connecting part of protective bar. The invention uses the tube in checking well to solve the defects of present combined tube-type checking well which can not be mounted with pedal and protective bar and avoid the accident of soil collapse in deep-well construction, while the special structure of tube can be one-time molded in production.
Description
Technical field
The present invention relates to the plumbing fitting field, particularly relate to a kind of manhole and deep-well that is applied in the large scale pipeline system and do the tubing in industry field.
Technical background
Manhole major part in the present large-scale underground piping system is that the underground in pipe path is built into the well body to ground by brick or cement, cover well lid again, the side of well body is provided with interface and comes connecting pipe, long, the obstruction easily of its engineering time, and when the staff checks pipeline in manhole, problem such as cave in easily, safety can't be protected.
As China Patent No. is that 00206354.9 utility model patent discloses a kind of pin-connected panel manhole, the pit shaft that comprises tubular, mark time on the well bore wall, it is characterized in that: pit shaft is horizontal or vertically assembled by concrete prefabricated element, connect by interface between each member, interface is flat mouth, tongue and groove, concavo-convex interface, reserves the rivet clasp bolt in the superiors and well lid connection.This utility model is assembled into manhole by concrete component, to a certain extent than brick or cement be built into more flexible, and be convenient to construction, improved labor productivity and operating efficiency.Yet it can not fundamentally address the above problem.
Comparatively advanced at present technology is to adopt plastic inspection well, promptly be provided with plastic conduit in well body inside, as Chinese patent application number is that 03131811.8 application for a patent for invention discloses a kind of integral type pipe manhole, it has the well body of an inner hollow, have at least a side to be provided with the trunk line connecting port and communicate perpendicular to the well body side surface of horizontal plane with the well intracoelomic cavity, well body top is provided with well body bellmouth, the inside wall of being close to well body bellmouth is provided with tube connector, the inside wall of being close to tube connector is provided with telescoping tube, and the telescoping tube top is connected with well lid and is covered by well lid.This technology has solved the problem that well body that brick or cement is built into is produced to a certain extent.
Yet above-mentioned plastic inspection well only is to insert plastic conduit to realize and being connected and preventing and cave in of ground in the well body, but common plastic conduit cannot install and mark time and protective guard, makes behind the deep drilling well body weight block work trouble, danger.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of the safe and reliable of manhole and construction band tubing of marking time easily that is applied to is provided.
In order to realize the foregoing invention purpose, the technical scheme of employing is:
The tubing that a kind of band is marked time, the inwall of described tubing is provided with marks time.
Owing to mark time in the inwall setting of tubing, thus this pipe applications when manhole, the constructor just can mark time by this and enter the shaft bottom easily.
In the technique scheme, described marking time to pipe material inner wall moulding one and along the vertical plane of pipe material inner wall or the projection that becomes a low-angle up to extend with vertical plane.The present invention is in conjunction with the characteristics of plastic conduit, when pipe production, can be directly in the pipe material inner wall moulding as the projection that mark time, compared with the concrete layout, the disposal molding but it is marked time needn't be constructed once more.
In order to make technique effect of the present invention more obvious, described upper surface of marking time also is provided with anti-skidding small lugs.Same, this anti-skidding small lugs also can be when pipe production disposal molding.
Both sides of marking time of the present invention are provided with the protective guard link.Because heavy duty service is very high to the requirement of safety,, further strengthened the safety of construction operation personnel work so the present invention can connect protective guard as required by in the both sides of marking time the protective guard link being set.
Particularly, described pipe material inner wall directly is provided with protective guard in the place, both sides of marking time.Protective guard can adopt arcuate structure, and the two ends of arc are connected in the inwall of tubing by fusion, and marking time then is positioned at the ring of encirclement of arc, and the staff slams when marking time, and can catch protective guard.
Tubing of the present invention is plastic cement tubing.Can adopt PE pipe, PP pipe or pvc pipe etc.
The present invention is by marking time in the pipe material inner wall setting, and the structure of the anti-skidding projection on marking time and the attachable protective guard in both sides of marking time, the well body that makes pipe applications can solve combined pipe fitting inspection well of the prior art when manhole can not be installed and mark time and protective guard, caused very big trouble and the existing dangerous operation of in the pipe inspection course of work, bringing, reach and get rid of the hazards that in the heavy duty service process, cause because of the earth landslide, and the invention process is convenient, and the ad hoc structure of tubing can one-shot forming when producing.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a partial enlarged drawing of the present invention;
Fig. 3 is applied to the structural representation of manhole for the present invention.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
Structural representation of the present invention as shown in Figure 1, tubing comprises outer wall 1, inwall 2, described inwall 2 is provided with marks time 3,3 the upper surface of marking time is provided with anti-skidding projection 4, inwall 2 also is provided with protective guard link 5 in 3 the both sides of marking time.Describedly mark time 3, the structure enlarged drawing of anti-skidding projection 4, protective guard link 5 as shown in Figure 2.
The structural representation that is applied to manhole of the present invention as shown in Figure 3, whole manhole comprises well lid 11, manhole cover base 12, regulates tubing 13, well body bellmouth 14, well body 15, well seat 17, the inside of well body 15 is provided with marks time 3,3 the upper surface of marking time is provided with anti-skidding projection 4, and the inboard of well body 15 also is provided with protective guard 51 in 3 the place, both sides of marking time.
Present embodiment is done well body 15 with mark time 3 tubing of band, and protective guard 51 connections in, make things convenient for the safety of carrying out and having improved greatly operation of inspection work operations.
When heavy duty service, after having bored well, band is marked time that 3 tubing is put in the well can convenient working, increases work efficiency and prevents the earth landslide.
