The utility model relates to a kind of plastic inspection well, relates in particular to a kind of enhanced plastic manhole that adopts the rotational moulding method to produce.
Background technology
For constructing of buried pipeline manhole, traditional method is after digging pit in place, the position of manhole, builds by laying bricks or stones or the shaft bottom of concreting with loam brick, builds pit shaft by laying bricks or stones with loam brick again and is communicated with buried pipeline, shaft in wall is smeared concrete, and walling crib and well lid are installed then.Adopt not only complex procedures of cast-in-place method, troublesome poeration, long construction period, the influence that engineering is subjected to artificial and natural environment is bigger, and quality is difficult for guaranteeing.
In order to solve the problem that above-mentioned brick manhole exists, plastic inspection well has appearred.The blowdown of making both at home and abroad at present mainly is divided into the injection moulding formula, is wound in pattern and die casting formula with straight tube plastic inspection well production technology: the injection moulding formula is produced plastic inspection well and is adopted raw material to be generally polyvinyl chloride (PVC), use plastic injection equipment and moulding form high-pressure injection molding, Wrapping formed plastic inspection well is a raw material with polyethylene (HDPE) then, and it is helically-wound shaped again to adopt extruder to extrude the base pipe; The die casting formula is produced and is taked to extrude the melting plastics with extruder earlier, is cast into plastic inspection well with press and moulding form again.The plastic inspection well equipment and the mould that adopt Shooting Technique to produce drop into huge, there is welding hidden danger in the plastic inspection well that adopts winding process to produce, and can not produce the eccentric type plastic manhole, if the plastic inspection well diameter 630 that adopts extrusion process production is to 1500mm, equipment and mould input are also very big, also have Combination Welding hidden danger.Also have the rotational moulding of employing method to produce plastic inspection well now, but both unresolved well head off-centre is beneficial to workman's safety assurance up and down, unresolved again rotational moulding method is produced the problem safe in utilization of plastic inspection well intensity.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that existing plastic inspection well exists, a kind of enhanced plastic manhole is provided, the utility model adopts the moulding of rotational moulding method, by the enhancing skeleton that is provided with, improved the intensity of plastic inspection well, promptly can be used for straight tube well, also can be used in the well head eccentric type plastic manhole.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of enhanced plastic manhole comprises the plastic well body, it is characterized in that: described well body is provided with the enhancing skeleton, strengthens skeleton and is coated in the plastics.
Described well body is provided with many ring stiffeners, and ring stiffener is coated in the plastics.
Described enhancing skeleton is steel frame or steel mesh formula skeleton.
The well chamber interior walls of described well body is provided with maintenance and marks time, and bottom, well chamber is provided with the blowdown chute that is communicated with arm.
Described manhole is a tapering and eccentric type plastic checking-well, and the well body comprises main well body and the upper well body that is the eccentric shape that closes up that is connected with main well body.
Described manhole is straight tube well.
Adopt advantage of the present utility model to be:
One, the utility model well body comprises enhancing skeleton and plastic well body wall, strengthens skeleton and is coated in the plastic well body wall, has strengthened the intensity of plastic inspection well.
Two, the utility model well body is provided with ring stiffener, between the well body wall and the outer borehole wall, combines with strengthening skeleton in ring stiffener is arranged on, and has further improved plastic inspection well intensity.
Three, the utility model skeleton is steel frame or steel mesh formula skeleton, is coated in the plastics, and is in aggregates with moulding plastics, and the intensity of manhole can be fully guaranteed.
