Abstract
The utility model provides a socket type plastic closing-in manhole, which belongs to the field of municipal engineering, and comprises a socket opening, a closing-in cone and a straight wall, wherein the straight wall is provided with the closing-in cone, and the closing-in cone is provided with the socket opening. Requirements on inner diameter space and the like is guaranteed as the specification of the manhole takes the inner diameter as a criterion, the socket opening which is conical is fine in socket positioning and guiding so that a certain sealing function is achieved, the section of each annular rib is trapezoidal so that annular rigidity of the manhole is effectively enhanced, and the wall of the manhole can be thinner so that materials are saved and the manhole is lightened. The socket type plastic closing-in manhole can be applied to various aspects such as drainage, gas, water supply, chemical valves, electric power, communication and the like.
Description
Technical field
The utility model relates to a kind of spigot-and-socket plastics closing in manhole, belongs to the municipal engineering field.
Background technology
Manhole is to be used for the rain 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 shortcomings such as complex structure, poor rigidity, cost height, for addressing this problem, needs design a kind of simple in structure, good rigidly, the manhole that cost is low.
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 spigot-and-socket plastics closing in manhole that cost is low.
The technical scheme of the utility model is: a kind of spigot-and-socket plastics closing in manhole comprises bell and spigot 1, closing in cone 2, straight wall 4.Be shaped on closing in cone 2 on the straight wall 4, be shaped on bell and spigot 1 on the closing in cone 2.
Equidistance is distributed with annular muscle 3 on the said manhole outer wall.
Said annular muscle 3 sections are trapezoidal.
Said bell and spigot 1 is concentric shape with closing in cone 2, and the diameter of bell and spigot 1 is less than closing in cone 2.
Said closing in cone 2 is taper.
Said spigot-and-socket plastics closing in manhole is an overall structure, the time processing moulding.The closing in downhole end adopts welding with being connected of well seat.
Said closing in cone 2 mouths are concentric or eccentric shape with well body portion center.
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) bell and spigot is taper, and the socket joint positioning and guiding is good, can play certain sealing function;
(3) 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;
(4) 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 front view of the utility model;
Each label is among the figure: 1: bell and spigot, 2: closing in cone, 3: annular muscle, 4: straight wall.
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 the figure, a kind of spigot-and-socket plastics closing in manhole comprises bell and spigot 1, closing in cone 2, straight wall 4.Be shaped on closing in cone 2 on the straight wall 4, be shaped on bell and spigot 1 on the closing in cone 2.Equidistance is distributed with annular muscle 3 on the manhole outer wall, and annular muscle 3 sections are trapezoidal.Bell and spigot 1 is concentric shape with closing in cone 2, and the diameter of bell and spigot 1 is less than closing in cone 2, and closing in cone 2 is taper.Spigot-and-socket plastics closing in manhole is an overall structure, the time processing moulding.The closing in downhole end adopts welding with being connected of well seat.Closing in cone 2 mouths are concentric shape with well body portion center.
Embodiment 2: as shown in the figure, a kind of spigot-and-socket plastics closing in manhole comprises bell and spigot 1, closing in cone 2, straight wall 4.Be shaped on closing in cone 2 on the straight wall 4, be shaped on bell and spigot 1 on the closing in cone 2.Equidistance is distributed with annular muscle 3 on the manhole outer wall, and annular muscle 3 sections are trapezoidal.Bell and spigot 1 is concentric shape with closing in cone 2, and the diameter of bell and spigot 1 is less than closing in cone 2, and closing in cone 2 is taper.Spigot-and-socket plastics closing in manhole is an overall structure, the time processing moulding.The closing in downhole end adopts welding with being connected of well seat.Closing in cone 2 mouths and well body portion center are eccentric shape.
