Description
Technical field
The utility model relates to drainage, more particularly, relates to a kind of municipal drain.
Background technology
In Urban Underground drainage system, gutter is indispensable important component part, is basic composition unit in plumbing network system and be connected hinge.Current subsoil drain is closed circular tubular, between every two joint gutters, same upper ground surface is set to collect and to converge the catch pit of the surface water.Such drainage pipe drainage efficiency is low, is unfavorable for the quick removing of the surface water, easily occurs the situation of city waterlogging because catch pit stops up.And its, current this cylindrical shape gutter is made up of cement, concrete, metal or plastic material etc., but reliability can not reach perfect condition always.
Utility model content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides that a kind of intensity is high, corrosion resistance strong and municipal drain rational in infrastructure, that drainage efficiency is high.
The utility model solves the technical scheme that its technical problem adopts: propose a kind of municipal drain, comprise plastic cement inner tube and cement or concrete outer tube, between described inner and outer tubes, be provided with cushion coat, the outer wall of described outer tube is provided with the first etch resistant layer, the inwall of described inner tube is provided with the second etch resistant layer, described outer tube inside is provided with along the axially extended Z-shaped waling of gutter, connect the interior ring reinforcing rib on summit inside described Z-shaped waling, with the outer shroud reinforcing rib that is connected described Z-shaped waling outer point, and the top of described municipal drain extends axially to offer along it and connects described the first etch resistant layer, outer tube, cushion coat, the opening of inner tube and the second etch resistant layer, the top of described opening is provided with screen pack.
According in an embodiment of the present utility model, described cushion coat is rubber layer.
According in an embodiment of the present utility model, described Z-shaped waling, interior ring reinforcing rib and outer shroud reinforcing rib are made by reinforcing bar.
Implement municipal drain of the present utility model, there is following beneficial effect: municipal drain of the present utility model adds the design of reinforcing rib by double-deck body, improved the intensity of gutter, and strengthen the corrosion resistance of body by inside and outside etch resistant layer; And excess surface water is drained fast by the opening extending along pipeline axial in this municipal drain, improve drainage efficiency, and stop various foreign material by screen pack, result in blockage in order to avoid foreign material enter pipe interior, because foreign material are blocked on the ground, clear up also very convenient.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the cross sectional representation of the municipal drain of an embodiment of the utility model;
Fig. 2 is the longitudinal cross-section schematic diagram of the municipal drain shown in Fig. 1;
Fig. 3 is the top view of the municipal drain shown in Fig. 1.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1-Fig. 3 shows respectively according to the cross sectional representation of the municipal drain 100 of an embodiment of the utility model, longitudinal cross-section schematic diagram and top view.As shown in the figure, this municipal drain 100 comprises the first etch resistant layer 110, outer tube 120, cushion coat 130, inner tube 140 and the second etch resistant layer 150 from outside to inside successively.Wherein, outer tube 120 is made up of cement or concrete, in outer tube 120, is provided with reinforcing rib.This reinforcing rib comprises Z-shaped waling 123 (shown in Figure 2), interior ring reinforcing rib 122 and outer shroud reinforcing rib 121.Z-shaped waling 123 extends axially along gutter, and interior ring reinforcing rib 122 is for connecting each summit of Z-shaped waling inner side, and outer shroud reinforcing rib 121 is for connecting each summit in Z-shaped waling outside.As shown in Figure 1, outer tube 120 is interior can be along many Z-shaped walings 123 are circumferentially set, and encircles reinforcing rib 122 and outer shroud reinforcing rib 121 along axially also can arranging of outer tube 120 in many simultaneously.Z-shaped waling 123, interior ring reinforcing rib 122 and outer shroud reinforcing rib 121 can be made up of reinforcing bar, for example, connect by welding manner.The setting of this reinforcing rib, can strengthen the intensity of body, makes the good reliability of gutter 100.The outer wall of outer tube 120 is provided with the first etch resistant layer 110.Inner tube 140 is plastic pipe, preferably pvc pipe.Between inner tube 140 and outer tube 120, cushion coat 130 is set, for reducing the wearing and tearing between outer tube 120 and inner tube 140.Cushion coat 130 preferred rubber layers, in certain different embodiment, cushion coat 130 is not limited to this, can adopt other various materials with damping characteristics.The inwall of inner tube 140 is provided with the second etch resistant layer 150, the second corrosion-resistant coatings 150 and the first corrosion-resistant coating 110 can be identical or different, preferably realizes by the mode that applies anticorrosive.
Further as shown in figures 1 and 3, the top of this municipal drain 100 is also provided with opening 170.Opening 170 extends axially along gutter 100, and connects the first etch resistant layer 110, outer tube 120, cushion coat 130, inner tube 140 and the second etch resistant layer 150, and in managing, space 160 is communicated with outside.Use so gutter 100 of design, the surface water can directly enter in pipe-line system along the opening extending on gutter 100, without converging to pipe-line system from catch pit as existing underground piping system, greatly accelerate the discharge of water, while avoiding the situations such as such as heavy rain, produced flood from road surface.And the top of opening 170 is provided with screen pack 180, stop various foreign material for crossing, in order to avoid entering pipe interior, foreign material result in blockage.Because foreign material are blocked on the ground, clear up also very convenient.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
