Description
Technical field
The utility model is mainly directed to the structural improvement of plastic inspection well.
Background technology
Plastic inspection well is generally made up of well seat, pit shaft, well lid and plastic inspection well spare and accessory parts, and it is arranged on the place of plastic drainage pipeline intersection, turning, caliber or gradient change place and drop; Or on straight line pipeline section at a certain distance place one plastic inspection well is set, be convenient to make regular check on, clean and dredging pipeline.
Because plastic inspection well is embedded in underground, maintenance conditions is not easily observe and detect, therefore it is also proposed higher standard to its some performances.
Conventional plastic manhole shaft and well seat junction lack powerful support when applying gravity to pit shaft and foreign object to pit shaft, when foreign object applies pressure to pit shaft, can cause well seat and pit shaft junction unbalance stress; Pit shaft and well seat junction depart from or pit shaft tilts, so that damage well body, finally affect well body application life.
In addition, plastic inspection well body pressure routinely structure is generally directly act on well seat arm socket joint oral area, pipeline and well seat arm bell and spigot is made to misplace or depart from, well seat and pipeline junction is caused to leak, also can cause well body built on the sand due to bottom pressurized inequality simultaneously, cause well body to tilt, affect well body life time.
In addition, bottom conventional plastic manhole, mostly be flat, run into well body pressure-bearing excessive time, easily cause and damage in varying degrees bottom well body, affect the application life of plastic inspection well too.
Further, conventional plastic manhole is connected oblique inserting as acclive in tool with pipeline or low-angle connects, often difficulty is large, and poor sealing performance, easily causes junction to leak, and understands direct polluted water resources or causes road surface to subside owing to leaking for a long time.
Summary of the invention
The purpose of this utility model is to provide a kind of novel plastic manhole, utilizes it can overcome deficiency of the prior art.
For achieving the above object, the utility model takes following design scheme:
A kind of novel plastic manhole, comprise well seat, pit shaft and well lid, between the well seat and pit shaft of plastic inspection well, add a gravity annular brace platform, this gravity annular brace platform is seated the top of well seat, is integrally made up of the platform watch box of the flat ring-shaped platform established and longitudinal direction; Be provided with the firm pressure-bearing body of ring type or circular table in the bottom of manhole well seat, or be provided with one group of vertical type reinforcing rib in the bottom of manhole well seat.
In described novel plastic manhole, the described flat ring-shaped platform width set is as 5.0cm ~ 8.0cm; Platform watch box height is at 15cm ~ 25cm.
In described novel plastic manhole, the ring wall thickness of the firm pressure-bearing body of described ring type is more than or equal to the wall thickness of plastic inspection well seat.
In described novel plastic manhole, at least there is the one in having structure: on the outer wall of platform watch box, be provided with one group of reinforcing rib; The ring wall of the firm pressure-bearing body of described ring type is provided with one group of reinforcing rib.
In described novel plastic manhole, also can be furnished with the angle socket and spigot joint that bending angle (θ) is 11.25 ° or 22.5 °.
The utility model has the advantages that:
1. pit shaft and well seat junction are more tight, connect more firm, make whole plastic inspection well more firm, well seat is born uniformly pressure that pit shaft and ground object act on pit shaft;
2. the steadiness of effective reinforced plastic manhole well body, can avoid well seat and pipeline junction pressurized to occur down to situation about departing from or leak;
3. add the holding capacity bottom well seat;
4. effectively can extend the application life of plastic inspection well body.

Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
Detailed description of the invention
Consult shown in Fig. 1 to Fig. 6, this novel plastic manhole comprises well seat 3, pit shaft 1 and well lid (not shown), and its main innovate point is: between the well seat 3 and pit shaft 1 of plastic inspection well, add a gravity annular brace platform 2; Be provided with the firm pressure-bearing body 5 (see Fig. 1 and Fig. 5) of ring type or circular table in the bottom of manhole well seat, or be provided with one group of vertical type reinforcing rib 6 (see Fig. 6) in the bottom of manhole well seat.
Consult Fig. 1, described gravity annular brace platform 2 is seated the top of well seat, is integrally made up of, shown in Fig. 2, Fig. 3 and Fig. 4 the platform watch box 21 of the flat ring-shaped platform 22 established and longitudinal direction.Described flat ring-shaped platform 22 width set is as 5.0cm ~ 8.0cm, in embody rule, the width (diameter) of this gravity annular brace platform will be determined according to the diameter of wellbore tubular and wall thickness, and the width of ring-shaped platform 22 should be made to be greater than the wall thickness of pit shaft as far as possible, and it is good for preferably having more 0.5cm.Platform watch box height is between 15cm ~ 25cm.This gravity annular brace platform can directly and plastic inspection well seat integrated injection molding, and its material is consistent with well seat material, without the need to change, without the need to secondary operations.It is according to plane uniform force principle and adapts to wellbore tubular circular design principle, and gravity ring-shaped platform can be made evenly to carry pressure when pit shaft and ground object act on pit shaft.Annular brace platform can solve well seat by pit shaft and ground object to pit shaft apply pressure act on well seat time, the technical problem of well body that well seat unbalance stress causes infringement, effectively prevent the problem that pit shaft departs from by gravity sinking, pit shaft and well seat and occurs.
Another innovative point of this novel plastic manhole is: the firm pressure-bearing body 5 (shown in Fig. 1 and Fig. 5) being provided with ring type or circular table in the bottom of manhole well seat, when plastic inspection well body is subject to longitudinal pressure, its well body pressure can major part act on the firm pressure-bearing body of annular bottom well seat or circular table through conduction, effectively prevent the generation that pipeline and well seat arm bell and spigot misplace or depart from.
An innovative point again of this novel plastic manhole is: or be provided with one group of vertical type reinforcing rib 6 (shown in Figure 6) in the bottom of manhole well seat, such design, add the holding capacity bottom well seat, add the steadiness of well body, effectively can extend the application life of well body.
This novel plastic manhole also can be furnished with the angle socket and spigot joint 4 (see Fig. 1, Fig. 2 and Fig. 6) that bending angle (θ) is 11.25 ° or 22.5 °.During use, as long as adjust angle socket and spigot joint 4 by rotating, the installation requirement of most of gradient can be met.
In described novel plastic manhole, also can have the one in having structure: on the platform watch box outer wall of gravity annular brace platform, be furnished with one group of reinforcing rib (can be net structure form, see the reinforcing rib 23 in Fig. 4; Also list structure form, the reinforcing rib 23 ' see in Fig. 5); Or one group of reinforcing rib (not shown) is provided with on the ring wall of the firm pressure-bearing body of described gravity annular, make well body more firm.
The various embodiments described above can not to depart under protection domain of the present utility model in addition some changes, thus above explanation to comprise and the structure shown in accompanying drawing should be considered as exemplary, and be not used to limit the protection domain that the utility model applies for a patent.
