Abstract
The utility model relates to a subgrade tarpaulin sheet with high strength, which is characterized in that the subgrade tarpaulin sheet is composed of an upper tarpaulin layer, a lower tarpaulin layer and a middle base fabric, embossing reinforce points are distributed on both the lower surface of the upper tarpaulin layer and upper surface of the lower tarpaulin layer, recessed holes corresponding to positions of reinforce points are disposed on the upper surface and the lower surface of the middle base fabric, and the reinforce points are installed in the recessed holes. The subgrade tarpaulin sheet has high strength, strong tension resisting capability, good bursting and tearing resistant property, high prick resisting capability, is not easy to be torn by ballasts, can effectively resist water and dredge road bed water drainage, slow down road bed smudge and hardening. Yellow sand is not needed cushioning, thereby saving cost of human power and materials.
Description
Technical field
The utility model relates to a kind of canvas cloth that is used for railway bed.
Background technology
Along with science and technology development, some advanced countries adopt high-strength waterproof cloth to be used for the waterproof of railway bed railway roadbed in succession in the world, solve the railway bed railway roadbed with this and fall into the disease that railway roadbed that groove, bedding spring, plate knot of ballast bed, impeded drainage etc. cause is risen soil because of quarrel capsule, ballast aggregate.But present existing canvas cloth intensity is not high, cracky, easily aging, do not play waterproof effect, all the time do not prevent and treat the rise soil generation of disease of railway roadbed effectively, along with continuing to increase of railway transporting amount, under the effect of high rate of traffic flow, heavily loaded rapid, the frequency that disease takes place in same circuit, same place is more and more higher, and the cycle is shorter and shorter, the be engaged in pressure of maintenance of worker is also increasing, and the difficulty of rail control is more and more difficult.
Summary of the invention
The purpose of this utility model then is at above-mentioned the deficiencies in the prior art, and a kind of intensity height, roadbed canvas cloth that big, the anti-bursting tear resistance of stretch-proof ability is good are provided.
The purpose of this utility model can realize by following measure:
A kind of high strength roadbed canvas cloth, it is characterized in that it comprises by upper and lower waterproofing course and middle base cloth forms, the upper surface of the soffit of last waterproofing course and following waterproofing course is evenly equipped with the hard point of projection, the upper and lower surface of middle base cloth be provided with upper and lower waterproofing course on the corresponding shrinkage pool in hard point position, each hard point is arranged in the described shrinkage pool.
The shrinkage pool up and down of above-mentioned middle base cloth can be communicated with, thereby the hard point on the upper and lower waterproofing course links into an integrated entity.
The beneficial effects of the utility model have:
1, intensity height, big, the anti-bursting tear resistance of stretch-proof ability are good, the anti-performance height of poking, and difficult is poked by ballast, and effectively waterproof is effectively dredged the railway roadbed draining, slows down ballast contamination, hardens, and repaiies the cycle in the corresponding prolongation railway roadbed.
2, mechanical strength height need not the underlay yellow ground in the construction, simplified construction operation, has saved the construction operation time.
3, because of need not to fill up yellow ground, saved the human and material resources cost.
4, be fit to adopt large-scale screen scarifier to throw the bed mechanized construction, the canvas cloth operation of pad shop has guaranteed that at quick section, operation quality that carries on construction work at night and job safety have been guaranteed traffic safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model includes upper and lower waterproofing course and middle base cloth three layer construction, the upper surface of the soffit of last waterproofing course 1 and following waterproofing course 3 is evenly equipped with the hard point of projection, this this protruding hard point correspondence is inserted in the shrinkage pool of middle base cloth 2 upper and lower surfaces, these shrinkage pools can run through up and down, thereby the hard point on close waterproofing course 1 and the following waterproofing course 3 fuses, and guarantees that it has better overall intensity.
Upper and lower waterproofing course of the present utility model is plasticated by synthetic rubber and natural rubber and is formed, middle base cloth then is can be made from mixed materials such as nylon or polyester-cotton blend, when upper and lower waterproofing course with make them closely connect together the formation overall structure by processing steps such as sulfurations again after middle base cloth is fitted, the various aspects of performance that the guarantor levies canvas cloth.
Other undeclared part that the utility model relates to is same as the prior art or adopt prior art to be realized.
Claims (2)
1, a kind of high strength roadbed canvas cloth, it is characterized in that it comprises by upper and lower waterproofing course and middle base cloth forms, the upper surface of the soffit of last waterproofing course and following waterproofing course is evenly equipped with the hard point of projection, the upper and lower surface of middle base cloth be provided with upper and lower waterproofing course on the corresponding shrinkage pool in hard point position, each hard point is arranged in the described shrinkage pool.
2, high strength roadbed canvas cloth according to claim 1 it is characterized in that the shrinkage pool up and down of described middle base cloth is communicated with, thereby the hard point on the upper and lower waterproofing course links into an integrated entity.
