Abstract
The utility model discloses a precast-bottom plate-type plastic inspection shaft, which comprises a pit-shaft and an bottom plate connected with the pit-shaft, wherein, the pit-shaft is a spiral winding plastic pit-shaft; the bottom plate is a concrete bottom plate; and a pipe branch is welded on the spiral winding plastic pit-shaft. The precast-bottom plate-type plastic inspection shaft adopts the spiral winding plastic pit-shaft, and the pit-shaft is delivered to a construction site and is put in the precast concrete bottom plate which is not solidified at the construction site after being bored and welded with the pipe branch so as to form the inspection shaft, thereby effectively solving the buoyancy force resistance problem of the plastic inspection shaft and the problem that the construction working procedure of a plastic-bottom plate-type plastic inspection shaft is fussy, and effectively lowering the cost.
Description
Technical field
The utility model relates to a kind of plastic inspection well that is used for plumbing, relates in particular to a kind of prefabricated panel formula plastic inspection well.
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 is divided into the injection moulding formula and is wound in pattern 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 polyvinylchloride, and Wrapping formed plastic inspection well is a raw material with polyethylene HDPE basically then.Existing plastic inspection well base plate is general to adopt the direct cutting of a plastic plate to form, again plastic bottom board that cutting is obtained and plastic inspection well well body welding fabrication.Adopt the plastic inspection well base plate of said structure because polyethylene board owing to the difficult problem of production equipment, technology, cost performance aspect, is essentially the 10mm thin plate so far on the market.As adopt the polyethylene board of this thickness, then since thickness low LCL and strength deficiency to reach the plastic inspection well force request, if adopt existing thicker polyvinylchloride sheet material, then because the material difference can not solve plastic inspection well polyethylene HDPE pit shaft and the welding of polyvinylchloride base plate.
Therefore the board-like plastic inspection well of existing plastic bottom for anti-floating must adopt modes such as increasing thickness, but has increased cost, is unfavorable for promoting; And the board-like plastic inspection well of existing plastic bottom is when construction and installation, must make foundation pad with loam brick, fine sand etc. toward contact, also increased cost.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that existing plastic inspection well base plate exists, and a kind of prefabricated panel formula plastic inspection well is provided.The utility model adopts spiral winding plastic pit shaft, transporting construction behind the pit shaft perforate branch pipe welded directly to the run pipe to and disposing in construction place moulding manhole on the prefabricated and also not solidified concrete floor, effectively solve plastic inspection well opposing buoyancy problem and the loaded down with trivial details problem of the board-like plastic inspection well working procedure of plastic bottom, and effectively reduced cost.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of prefabricated panel formula plastic inspection well comprises pit shaft and the base plate that is connected with pit shaft, it is characterized in that: described pit shaft is a spiral winding plastic pit shaft, and described base plate is a concrete floor, is welded with arm on the spiral winding plastic pit shaft.
Described spiral winding plastic pit shaft is spiral planomural internal layer well bore wall.
Described spiral winding plastic pit shaft comprises spiral planomural internal layer well bore wall, the outer well bore wall of spiral arch, and outer well bore wall and internal layer well bore wall are molten to be connected.
Described arch is corrugated arch or trapezoidal shape arch.
Be provided with strength bar in the plastics arcuate strips of described outer well bore wall.
The inwall of described internal layer well bore wall is provided with maintenance and marks time.
Adopt advantage of the present utility model to be:
One, the utility model adopts spiral to twine pit shaft, and simple and reliable process is combined into plastic inspection well with concrete floor again, can effectively solve plastic inspection well opposing buoyancy problem.
Two, the utility model adopts spiral to twine pit shaft, is combined into plastic inspection well with concrete floor again, can effectively solve the loaded down with trivial details problem of the board-like plastic inspection well working procedure of plastic bottom.
Three, the utility model adopts spiral to twine pit shaft, is combined into plastic inspection well with concrete floor again, can effectively reduce the plastic inspection well cost.
Four, in the identical ring stiffness plastic inspection well of same material, save material more than 1/4, under the situation that the oil product plastics significantly appreciate, reduced manufacturing cost.
Five, strength bar is set in pipe, has effectively improved the ring stiffness and the intensity thereof of plastic inspection well, particularly outstanding when diameter surpasses 1000 millimeters, and its structure is more firm.
