[0002] With the rapid development of my country's economy, various types of chemical enterprises and factories have increased rapidly. In order to prevent the road surface from being corroded by acids and alkalis, cement concrete pavement is generally used on the transportation roads within the newly built chemical enterprise plant area, while the municipal roads in front of the plant are generally asphalt pavement. In the connection area between the concrete pavement and the asphalt pavement, due to the large traffic volume of large vehicles and heavy-loaded vehicles, the pavement bearing capacity and anti-seepage requirements of the connection area are generally more stringent. If the pavement bearing capacity is insufficient and the connection of the pavement connection area is not firm enough, it is very easy to produce large cracks due to uneven settlement; if the anti-seepage measures are not properly set, acids and alkalis will seep from the joints and asphalt pavement to the bottom of the municipal road without chemical pollution anti-seepage measures, which is very easy to pollute the underground soil at the bottom of the road.

[0003] At present, the connection structure between new and old roads is relatively simple, which is not applicable to roads with large traffic volume of heavy-loaded vehicles and anti-seepage requirements. Utility Model Content

[0004] The utility model aims to provide a connection structure between a chemical anti-seepage road and an ordinary road to solve the problems in the above background.

[0011] Preferably, a geogrid 1 is provided on the bottom surface of the common road surface layer, and a geogrid 2 is provided on the bottom surface of the end portion of the water-stabilizing layer below the common road surface layer.

[0012] Preferably, the first geogrid is a glass fiber geogrid, and the second geogrid is a biaxially stretched plastic geogrid.

[0030] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0031] In the description of the embodiments of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0032] Reference Figure 1-2 A connection structure between a chemical anti-seepage road and an ordinary road is provided, located at one end of a newly built chemical anti-seepage road, and is used to connect the newly built chemical anti-seepage road with an existing municipal ordinary road 11. The connection structure includes a chemical anti-seepage road surface layer 1 and an ordinary road surface layer 2 arranged adjacent to each other, a caulking connection portion 3 is provided at the joint between the two, and a water-stabilizing layer 4, a cushion layer 5 and an anti-seepage layer 6 are provided at the bottom of the two in sequence, and the ends of the water-stabilizing layer 4, the cushion layer 5 and the anti-seepage layer 6 located below the ordinary road surface layer 2 are distributed in an inverted step shape, and a transition plate 7 connecting the chemical anti-seepage road surface layer 1 is provided between the ordinary road surface layer 2 and the water-stabilizing layer 4.

[0033] During construction, graded excavation and stepping are carried out at the end of the original municipal ordinary road 11. The shape and size of the stepping are complementary to the inverted step-shaped distribution structure of the water-stabilizing layer 4, the cushion layer 5 and the anti-seepage layer 6, so that the connection structure is firmly connected and tightly combined with the original municipal ordinary road 11. The chemical anti-seepage road surface layer 1, the water-stabilizing layer 4, the cushion layer 5 and the anti-seepage layer 6 are part of the newly built chemical anti-seepage road, and are constructed in an integrated manner with other roads within the factory. The chemical anti-seepage road surface layer 1 is cast with cement concrete to improve the anti-seepage and acid-alkali corrosion resistance. The materials of the water-stabilizing layer 4 and the cushion layer 5 can be consistent with the layers of the original municipal ordinary road 11 outside the factory to improve the bonding strength with each open area; the ordinary road surface layer 2 is arranged between the original municipal road surface layer after the open step and the chemical anti-seepage road surface layer 1, and its material is consistent with the surface layer of the original municipal ordinary road 11 outside the factory, and is paved with asphalt to improve the bonding strength at the junction of the newly paved road and the original municipal ordinary road 11; the caulking connection part 3 can ensure the bonding strength and anti-seepage performance of the junction between the ordinary road surface layer 2 and the chemical anti-seepage road surface layer 1, and the transition plate 7 is cast with cement concrete to improve the supporting strength of the ordinary road surface layer 2 and reduce the uneven settlement at the junction of the chemical anti-seepage road surface layer 1 and the ordinary road surface layer 2.

[0034] Due to the connection position of the road surface layer and the strong permeability of the asphalt pavement itself, if chemical pollutants such as acid and alkali infiltrate along the above structure to the bottom of the municipal road without chemical pollution anti-seepage measures, it is very easy to pollute the underground soil at the bottom of the road. Therefore, in this embodiment, the bottom surface of the end of the water-stabilizing layer 4, cushion layer 5 and anti-seepage layer 6 below the ordinary road surface layer 2 is set as a slope, with the top of the slope facing the ordinary road surface layer 2 and the bottom facing the chemical anti-seepage road surface layer 1, so as to guide the infiltrated acid and alkali chemical pollutants to flow to the side of the newly built road with the anti-seepage layer 6. The anti-seepage layer 6 isolates the chemical pollutants from the underground soil to avoid polluting the underground environment. The slope of the above slope can be set according to actual construction needs, and no specific restrictions are made here.

[0035] The above-mentioned caulking connection part 3 includes a caulking plate 3-1, a backing layer 3-2 and a caulking sealing material layer 3-2 which are arranged in sequence from bottom to top. The caulking plate 3-1 can be a closed-cell polyethylene foam plastic plate, the backing layer 3-2 can be an elastic polyethylene foam rod, and its diameter should be not less than 1.25 times the seam width. The caulking sealing material layer 3-2 can be made of silicone sealant and should be 2mm to 3mm below the ground.

[0036] In order to further improve the structural stability of the connection structure, a tie rod 8 is provided in the connection structure in this embodiment, and the two ends of the tie rod 8 are respectively fixed in the chemical anti-seepage road surface layer 1 and the transition plate 7 to prevent the relative displacement and expansion of the cement concrete structures on both sides. During construction, the tie rod 8 can be made of HPB300 grade steel bars, and it is evenly arranged in a row along the joint between the chemical anti-seepage road surface layer 1 and the transition plate 7. The length, diameter, spacing and number of the tie rod 8 can be configured according to actual construction requirements, and no specific restrictions are made here.

[0037] During construction, each layer of the connection structure is poured or laid in layers, wherein: the ordinary road surface layer 2 includes several structural layers distributed vertically, and the several structural layers are distributed in an inverted step shape toward the end of the transition plate 7, and the end shape of the transition plate 7 is complementary and adapted thereto to improve the connection tightness of the road layers.

[0038] Due to differences in construction requirements for roads in different areas, there may be differences in thickness between new and old roads. Generally, the thickness of internal factory roads is thinner than that of municipal roads to save costs. When the road surface elevation is consistent, the roadbed elevation inside the factory must be higher than that outside the factory. In order to improve the position correspondence and connection tightness of each structural layer between the internal factory roads and the external municipal roads, the water-stable layer 4 and the cushion layer 5 inside the factory will be higher than the part outside the factory. Therefore, in the connecting structure, the middle parts of the water-stable layer 4 and the cushion layer 5 are inclined, and the side of the water-stable layer 4 away from the chemical anti-seepage road surface layer 1 is upwardly protruding to have a water-stable layer 4 structure adapted to the external factory road, thereby improving the bonding strength of the water-stable layer 4 of the new and old roads, and the side of the transition plate 7 away from the chemical anti-seepage road surface layer 1 is tightly connected to the water-stable layer 4 at that position.

[0039] In addition, in order to improve the road bearing capacity, the present embodiment is provided with a geogrid 1 9 on the bottom surface of the ordinary road surface layer 2, and a geogrid 2 10 is provided on the bottom surface of the end of the water-stabilizing layer 4 located below the ordinary road surface layer 2. During implementation, the geogrid 1 9 can be a glass fiber geogrid, which has high tensile strength, low elongation, and high anti-deformation ability; the geogrid 2 10 can be a biaxially stretched plastic geogrid, which has great tensile strength and strain rate in the vertical and horizontal directions, can prevent the water-stabilizing layer 4 and its upper structure from collapsing, and improve the service life of the roadbed.

[0040] The anti-seepage layer 6 can be made of a two-cloth-one-film composite geomembrane, which includes an anti-seepage membrane and protective layers on both sides of the anti-seepage membrane. To ensure the anti-seepage effect, the anti-seepage membrane should have a thickness greater than or equal to 1.5 mm.

[0041] Compared with the prior art, the beneficial effects of the utility model are: the ordinary road surface layer 2, the water-stabilizing layer 4, and the cushion layer 5 in the connection structure have a strong bonding force with the various structural layers of the municipal road, and it is not easy to produce settlement joints. The transition plate 7 and the pull rod 8 can improve the supporting strength of the ordinary road surface layer 2, and avoid uneven settlement causing settlement joints at the connection position between the chemical anti-seepage road surface layer 1 and the ordinary road surface layer 2. At the same time, the caulking connection part 3 arranged at the connection position can effectively prevent seepage and splitting, thereby improving the bearing capacity of the connection structure; the slope setting of the bottom surface of the end of the water-stabilizing layer 4 and the cushion layer 5 can guide chemical pollutants to flow to the side of the newly built road with the anti-seepage layer 6, thereby avoiding pollution of the underground environment.

[0042] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
