Abstract

The utility model discloses a synthetic rubber runway structure with permeability. A runway surface layer (10) is paved on the plain foundation ground formed by the civil engineering, the runway surface layer (10) comprises a surface layer main body (11) which is made of permeable gravel, fiber, cracked rubber and bonding agent in a mixed way, a surface anti-sliding layer (12) formed by the rubber grains mixed with bonding agent paved on the surface layer main body (11), and a water permeable layer (13) formed by the gravel mixed with bonding agent below the surface layer main body (11). Compared with the prior technology, the utility model has the advantages of high elasticity, no distortion and no water accumulation.

Description

The infiltrative synthetic rubber runway of tool structure

Technical field the utility model relates to the paving that is exclusively used in stadium or playing field, particularly relates to the runway paving of field fabrication.

Artificial course's pavement structure of background technology prior art as shown in Figure 4, be followed successively by on-slip polyurethane (PU) particle 91, PU first coating layer 93, PU second coating layer 92, pitch surface layer 94, pitch articulamentum 95, end oil 96, gravel grating 97, rough sand 98 and mackintosh 99 etc. from top to bottom, this runway structure is not only laid very trouble layer by layer in construction, and every laying one deck, then must detect once, thus time-consuming, take a lot of work and the cost height.

In addition, because PU material possess hydrophilic property not, so the easy ponding of runway when rainy, again because airtight, do not seep water, thereby easily the aqueous vapor of humidity is lodged between each layer of runway, cause material not good or the bad place that constructs (can't avoid) cause the PU pull-up to fall, so cost of maintenance are very high.And the particle on PU top layer is the spreading construction, and adhesion area is little, and the PU particle easily comes off because of rubbing.

The summary of the invention the purpose of this utility model be to avoid above-mentioned the deficiencies in the prior art part and a kind of gas permeability is proposed, seepage of water is good, the PU particle of surperficial on-slip layer is not allowed the infiltrative synthetic rubber runway of caducous tool structure.

The purpose of this utility model can be by realizing by the following technical solutions:

Design, the infiltrative synthetic rubber runway of a kind of tool of use structure; the runway cover of establishing on the formed smooth ground of civil engineering upper berth; described runway cover comprises the pervious layer that is formed by gravel mixing bonding agent below the surface layer body that is mixed and made into by permeable gravel, fiber, crumb and bonding agent and surperficial on-slip layer of laying that is formed by rubber grain mixing bonding agent and the surface layer body on this surface layer body.

Compared with prior art, the utlity model has following advantage:

1. adopt surface layer body that is mixed and made into by permeable gravel, fiber, crumb and bonding agent and the air-permeable layer of making by gravel mixing bonding agent, compare with the runway of repeatedly laying layer of the prior art, not only save job step, working time and detection number of times, and have high resiliency, indeformable and advantage such as ponding not in the use;

2. the particle bonding way of surperficial on-slip layer of the present utility model is laid for stirring synthetic, and the whole grain of particle is long-pending all to contact bonding agent, thereby is not easy to come off;

3. the utility model runway cover thickness is the twice of existing runway thickness, thus the abrasion resistance height, and when allotment material mixed proportion, the adjustable surface layer of different elasticity and hardness of allotting is to be used in different athletic grounds;

4. elastomeric material can reclaim tire twice laid in addition by automobile, helps environmental protection, and can reduce the runway manufacturing cost.

The specific embodiment is described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.

The infiltrative synthetic rubber runway of a kind of tool structure; it is the runway cover of establishing on the formed smooth ground of civil engineering upper berth 10; as shown in Figure 1; described runway cover 10 comprise the surface layer body 11 that is mixed and made into by permeable gravel, fiber, crumb and bonding agent and the surperficial on-slip layer 12 that forms by rubber grain mixing bonding agent on this surface layer body 11, laid and surface layer body 11 below the pervious layer 13 that forms by gravel mixing bonding agent.Described surface layer body 11 thick 22～25 centimetres, the mixed proportion of its material is: gravel is 19～20 Kilograms Per Square Meters; Crumb is 9～10 Kilograms Per Square Meters; Fiber is 1.2～1.5 Kilograms Per Square Meters; The polyurethane bonding agent is 1.2～1.5 Kilograms Per Square Meters.Described surperficial on-slip layer 12 thick 3～5 centimetres, its material mixed proportion is: the rubber grain is 1.0～1.2 Kilograms Per Square Meters, the polyurethane bonding agent is 1.2～1.5 Kilograms Per Square Meters.Described pervious layer 13 thick 50～60 centimetres, its material mixed proportion is: gravel is 60～70 Kilograms Per Square Meters, polyurethane bonding agent 2.4～3.0 Kilograms Per Square Meters.Describedly handle formed runway by pervious layer 13, surface layer body 11 and surperficial on-slip thereof, in security test, no matter under any weather, all have good elasticity, abrasion resistance, anti-nail, anti-caltrop, stretching and combustibility, and non-ageing characteristic is all arranged in fine, rainy day.

As shown in Figure 1, in the sandy gravel stratum of described ground, be embedded with toughness water-permeable pipe 20, in order to collecting a large amount of rainwater that penetrate by runway cover, and guide it to flow into gutter system, rainwater is unlikely accumulates in ground, keep the water permeability of rubber track.

Described water-permeable pipe 20 is by molded the forming of rubber grain mixing polyurethane bonding agent, and the rainwater that penetrates runway cover can directly infiltrate in the water-permeable pipe 20.As Fig. 2, shown in Figure 3, described water-permeable pipe 20 is the square-outside and round-inside long tube, in order to increase water-permeable pipe intensity and with the contact area in the external world, increase the ponding ability.For several water-permeable pipes 20 are linked to each other, water-permeable pipe 20 two ends have concavo-

convex joint

21,22 respectively.The latter half inner edge of described water-permeable pipe 20 is provided with waterproofing course 23, is used for collecting the rainwater that its first half penetrates.

Make the used rubber grain of described water-permeable pipe 20, processed by the waste vapour vehicle tyre that reclaims, twice laid helps to reduce cost, and helps environmental protection.Described toughness water-permeable pipe is not limited to use in this synthetic rubber runway ground, also applicable in other artificial courses and the court ground.
