Abstract
The utility model provides a welded type plastic inspection well with a shell nosing, belonging to the field of municipal engineering. The welded type plastic inspection well with the shell nosing comprises a welded interface, a shell nosing cone and a straight wall. The shell nosing cone is arranged on the straight wall on which the welded interface is arranged, and welded bulges are arranged on the circumference at the top end of the welded interface and on the circumference at the bottom end of the straight wall. The welded type plastic inspection well with the shell nosing adopts the requirements that the inner diameter is taken as the benchmark, the inner diameter space is guaranteed and the like. The section of an annular rib is trapezoid, the rigidity of the annular rib can be effectively improved, the wall of the well can be relatively thin, the material is saved, and the weight is reduced. The plastic inspection well with the shell nosing can be applied to various aspects such as water drainage, gas, water supply, chemical industry valve, electric power, communication and the like.
Description
Technical field
The utility model relates to a kind of welded type 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 complex structure, poor rigidity, and bonding strength and sealing are poor, and shortcomings such as cost height for addressing this problem, need 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 welded type plastics closing in manhole that cost is low.
The technical scheme of the utility model is: a kind of welded type plastics closing in manhole comprises welding junction 1, closing in cone 2, straight wall 4.Be shaped on closing in cone 2 on the straight wall 4, be shaped on welding junction 1 on the closing in cone 2, welding junction 1 top circumference is shaped on solder-bump respectively with straight wall 4 bottom circumference.
Equidistance is distributed with annular muscle 3 on the manhole outer wall.
Said annular muscle 3 sections are trapezoidal.
Said welding junction 1 is concentric shape with closing in cone 2.
Said closing in cone 2 is taper.
Said closing in cone 2 mouths are concentric or eccentric shape with well body portion center.
Said welded type plastics closing in manhole is an overall structure, the time processing moulding.Other of closing in well two ends and well seat is connected and adopts welding.
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) 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: welding junction, 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 welded type plastics closing in manhole comprises welding junction 1, closing in cone 2, straight wall 4.Be shaped on closing in cone 2 on the straight wall 4, be shaped on welding junction 1 on the closing in cone 2, welding junction 1 top circumference is shaped on solder-bump respectively with straight wall 4 bottom circumference.Equidistance is distributed with annular muscle 3 on the manhole outer wall, and annular muscle 3 sections are trapezoidal.Welding junction 1 is concentric shape with closing in cone 2.Closing in cone 2 is taper, and closing in cone 2 mouths are concentric shape with well body portion center.Welded type plastics closing in manhole is an overall structure, the time processing moulding.Other of closing in well two ends and well seat is connected and adopts welding.
Embodiment 2: as shown in the figure, a kind of welded type plastics closing in manhole comprises welding junction 1, closing in cone 2, straight wall 4.Be shaped on closing in cone 2 on the straight wall 4, be shaped on welding junction 1 on the closing in cone 2, welding junction 1 top circumference is shaped on solder-bump respectively with straight wall 4 bottom circumference.Equidistance is distributed with annular muscle 3 on the manhole outer wall, and annular muscle 3 sections are trapezoidal.Welding junction 1 is concentric shape with closing in cone 2.Closing in cone 2 is taper, and closing in cone 2 mouths and well body portion center are eccentric shape.Welded type plastics closing in manhole is an overall structure, the time processing moulding.Other of closing in well two ends and well seat is connected and adopts welding.
