Abstract
The utility model provides a plastic straight-wall inspection well, and belongs to the field of municipal engineering. An inspection well is formed by straight wall in an encircling manner; annular ribs are arranged on the outer wall of the straight wall; welding protruding structures are arranged on the circumferences at the top and the bottom ends of the straight wall; the annular ribs are equidistantly distributed on the outer wall of the straight wall; and the sections of the annular ribs are trapezoidal. The specification of the plastic straight-wall inspection well is determined on the basis of the internal diameter, requirements on the internal diameter space and the like are met, and the sections of the annular ribs are trapezoidal, so that the annular rigidity can be effectively improved, the well wall can be thinner, materials are saved, the weight is reduced, the plastic straight-wall inspection well is simple in structure, high in annular rigidity, low in manufacturing cost and convenient to maintain, and automatic control and positioning stroke control can conveniently realized.
Description
Technical field
The utility model relates to a kind of plastic inspection well, and the straight wall manhole of particularly a kind of plastics belongs to the municipal engineering field.
Background technology
Manhole is to be used for rainwater, sewage vent line; The vertical shaft of on the underground utilities position, building at a certain distance; Pipeline in order to connect different tube diameters, different directions, differing heights uses; The main nurse people of keeping makes regular check on dredging pipeline, removes the mud foreign matter, prevents line clogging etc., is one of urban road underground foundation facility.Because plastic drain-pipe and plastic inspection well are in light weight, corrosion-resistant; The tubing ring stiffness can design as required; Sealing joint property is good, and is non-leakage, can effectively prevent phreatic pollution; And speed of application, hydraulics, cost performance etc. all are superior to cement sewer pipe and the brick manhole of sand-lime, therefore in rain sewage drainage systems such as town road, building sub-district, use in a large number.Existing plastic inspection well has Zhi Bijing, closing in well and pipe fitting well, but all has complex structure, poor rigidity, and bonding strength and sealing are poor, problems such as cost height.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, good rigidly, and bonding strength is high, good airproof performance, the manhole that cost is low.
The technical scheme of the utility model is: the straight wall manhole of a kind of plastics, surround manhole by straight wall 1, and straight wall 1 outer wall is shaped on annular muscle 2, and the circumference of straight wall 1 top and bottom has the solder-bump structure respectively.Annular muscle 2 is equally spaced on the outer wall of straight wall 1, and annular muscle 2 sections are trapezoidal.
The straight wall manhole of said plastics is an overall structure, the time processing moulding, and welding is all adopted with being connected of other pipe network part in straight wall 1 two ends.
The utility model can pass through preparation method's time processing moulding such as the moulding of Integratively hot extrude cold presswork, Integratively rotational moulding machine-shaping, Integratively mold pressing machine-shaping, the notes machine-shaping of Integratively pressure and Integratively injection moulding machine-shaping to be made.
The beneficial effect of the utility model is:
(1) employing of manhole specification is a benchmark with the internal diameter, guarantees requirements such as inner diameter volume;
(2) annular breaking of muscle and tendon face is trapezoidal, can effectively improve ring stiffness, and the borehole wall can be thinner, saves material, weight reduction;
(3) welding is all adopted with being connected of other part in straight wall well two ends, and bonding strength is high, good airproof performance;
(4) straight wall well construction is simple, and ring stiffness is good, low cost of manufacture;
(5) can be applicable to the plastic inspection well of each side such as draining, combustion gas, feedwater, chemical industry valve, electric power, communication.
Description of drawings
Fig. 1 is the section of structure of the utility model;
Fig. 2 is the vertical view of the utility model;
Each label is among the figure: 1: straight wall, 2: annular muscle.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further, but the content of the utility model is not limited to said scope.
Embodiment 1: as shown in Figure 1, the straight wall manhole of a kind of plastics surrounds manhole by straight wall 1, and straight wall 1 outer wall is shaped on annular muscle 2, and the circumference of straight wall 1 top and bottom has the solder-bump structure respectively.Annular muscle 2 is equally spaced on the outer wall of straight wall 1, and annular muscle 2 sections are trapezoidal.
The straight wall manhole of said plastics is an overall structure, the time processing moulding, and welding is all adopted with being connected of other pipe network part in straight wall 1 two ends.
Claims (3)
1. straight wall manhole of plastics is characterized in that: surround manhole by straight wall (1), straight wall (1) outer wall is shaped on annular muscle (2), and the circumference of straight wall (1) top and bottom has the solder-bump structure respectively.
2. the straight wall manhole of plastics according to claim 1 is characterized in that: annular muscle (2) is equally spaced on the outer wall of Zhi Bi (1).
