Abstract
The utility model discloses a compound plastic inspection well, and relates to the plastic inspection wells in the field of municipal facilities. The compound plastic inspection well is high in strength and is resistant to corrosion. According to the technical scheme, the compound plastic inspection well comprises an inspection well body and connector pipe fittings matched with connectors formed in the circumferential direction of the inspection well body, wherein the inspection well body is of a three-layer structure, the inner layer is a polyurethane elastomer layer, the middle layer is a packing layer, and the outer layer is a high-density polyethylene resin layer. The compound plastic inspection well has the advantages that the inspection well body is of the three-layer structure, the polyurethane elastomer layer at the inner layer effectively improves the abrasion resistance of the inspection well body and is high in scaling-resisting capacity, the packing layer at the middle layer plays a role in sealing to a certain degree, the high-density polyethylene resin layer at the outer layer is not corroded easily and does not fracture easily, the abrasion resistance, the corrosion resistance and the strength of the inspection well body are improved, the service life of the inspection well body is prolonged, and the manufacturing cost is low.
Description
Technical field
The utility model relates to municipal facilities field, is specially a kind of plastic cement manhole.
Background technology
Further enforcement along with Chinese society development and new countryside construction, various infrastructure is all being built in each metropolis, the whole nation, but when building various infrastructure, for the design that is embedded in the network of underground such as plumbing under road, communication, just seem very important.Manhole as pipelines such as plumbing, communications still adopts traditional brick well pattern mostly, but some careful masses find, part building site is adopting a kind of emerging plastic cement manhole, this plastic cement manhole is connected with plastic conduit, because this kind of plastic cement manhole exists the advantages such as quality is light, sealing joint is good and corrosion-resistant, therefore just progressively replace traditional brick well.Existing plastic cement manhole is mostly by disposable injection molded, its bulk strength is lower, adding plastic cement manhole is embedded in underground for a long time, be subject to for a long time the corrosion of water soaking, various acid, alkali, salt, thereby working environment is very severe, very easily impaired and lose waterproof ability, polluted underground water source.
Summary of the invention
The purpose of this utility model is to provide a kind of have high strength, corrosion resistant plastic cement manhole, solves the problems such as intensity that in prior art, plastic cement manhole exists is low, perishable.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A complex plastic manhole, comprises manhole body, the interface pipe fitting that the interface of circumferentially offering with manhole body matches, it is characterized in that: described manhole body comprises three layer construction, internal layer is polyurethane elastomer layer, and middle level is packing layer, and skin is high-density polyethylene resin layer.
Further, packing layer is Vestolit plate.
Further, in packing layer, be inlaid with reinforcing rib.
Further, reinforcing rib is circumferentially uniformly distributed along manhole body.
The beneficial effects of the utility model are:
1, manhole body comprises three layer construction, abrasion resistance, ant-scaling ability that the polyurethane elastomer layer of internal layer has effectively improved manhole body are strong, the packing layer in middle level plays sealing function to a certain extent, outer field high-density polyethylene resin layer is difficult for being corroded, breaking, abrasion resistance, corrosion resistance and the intensity of manhole body have been improved, extended the application life of manhole body, and low cost of manufacture.
2, the filler of packing layer adopts Vestolit plate, has good water proofing property, fire-resistant, acid-alkali-corrosive-resisting, and filling property is good, can improve manhole sealing, extended application life of manhole body.
3, in packing layer, be inlaid with reinforcing rib, effectively improved the intensity of manhole body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of the utility model manhole body;
Wherein Reference numeral is: 1-manhole body, 2-interface pipe fitting, 3-polyurethane elastomer layer, 4-packing layer, 5-high-density polyethylene resin layer, 6-reinforcing rib.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment mono-
As shown in the figure, a kind of complex plastic manhole, comprises manhole body 1 and interface pipe fitting 2, and manhole body 1 surface offers at least interface, and a plurality of interface is along being circumferentially uniformly distributed of manhole body 1, and the unnecessary interface of part can be used as spare interface.Interface pipe fitting 2 is connected with the interface on manhole body 1, its connected mode can be in welding, the bonding or direct insertion of one end by structure pipe fitting 2 interface, if adopt directly the connected mode in interface inserted in one end of structure pipe fitting 2, need add sealing mat and prevent out polluted underground water source of manhole or ducted sewage permeation between structure pipe fitting 2 and interface.Manhole body 1 comprises three layer construction, and internal layer is polyurethane elastomer layer 3, and middle level is packing layer 4, and skin is high-density polyethylene resin layer 5.Wherein, the preferred thermoplastic polyurethane elastic body of polyurethane elastomer layer 3 (being called for short TPU), its object is that thermoplastic polyurethane elastic body (being called for short TPU) has excellent in abrasion resistance, hardness is large, intensity is high, good springiness, low temperature resistant, there are good oil resistant, ant-scaling ability, chemical-resistant resistance and environmental resistance, hydrolytic stability in wet environment is higher, thereby in pipeline, for a long time current are little to the wearing and tearing of inner surface of pipeline, erosion degree is low, less scaling, cost is low; Packing layer 4 can select the materials such as elastic caoutchouc, Vestolit plate, polystyrene board to fill, the preferred Vestolit plate of the present embodiment, it has good water proofing property, fire-resistant, acid-alkali-corrosive-resisting, and filling property is good, can improve manhole sealing, extended application life of manhole body; Because erosion, the water imbibition of the most of soda acids of high-density polyethylene resin layer 5 ability are less, be difficult for being corroded, damaging, improved abrasion resistance, corrosion resistance and the intensity of manhole body, extended the application life of manhole body.
Manhole body 1 adopts three layer construction to form, outer field high-density polyethylene resin layer 5 mainly plays anticorrosive effect, the polyurethane elastomer layer 3 of internal layer mainly plays waterproof, wear-resisting effect, pass through three layer construction, improved intensity, abrasion resistance, the corrosion resistance of manhole, improve manhole sealing, extended application life of manhole body.
Embodiment bis-
On the basis of embodiment mono-, in packing layer 4, be inlaid with reinforcing rib 6, the cross section of this reinforcing rib 6 is trapezoidal, has increased the vertical load of reinforcing rib 6.This reinforcing rib 6 can be along the strip reinforcing rib of the axial placement of manhole body 1, and the ring-type that can circumferentially place along manhole body 1 is strengthened warp, also can be latticed integral body and wrap manhole body 1.
By inlay reinforcing rib 6 in packing layer 4, can effectively improve the intensity of manhole body.
