Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a curbstone-free asphalt pavement construction method. Background Art

[0002] As asphalt itself is polluting, asphalt pavement construction is easy to pollute the surrounding environment. Traditional asphalt pavement construction requires the installation of curbs on both sides of the designed position of the asphalt pavement to block the pollution of the soil and plants on both sides during the subsequent pouring of asphalt. However, the cost of the curb itself as a stone material and the transportation cost are relatively high, and the flatness test is also required during the construction of the curb, which takes up construction time. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a curb-free asphalt pavement construction method, which uses baffles instead of curbs, reduces production costs and transportation costs while speeding up construction speed.

[0004] To achieve the above object, the technical solution adopted by the present invention is a curb-free asphalt pavement construction method, comprising the steps of:

[0005] Step 1: construct a roadbed at the designed position of the asphalt pavement so that the top surface of the roadbed is flush with the top surface of the planting soil of the green belts on both sides;

[0006] Step 2: Connect baffles on both sides of the planting soil of the green belts on both sides at the top of the roadbed, so that the baffles are arranged along the length direction of the roadbed, and the top elevation of the baffles is flush with the top design elevation of the asphalt pavement;

[0007] Step 3: pouring coarse aggregate asphalt on the inner side of the two baffles until the designed position, backfilling the first backfill soil on the outer side of the two baffles, so that the top elevation of the first backfill soil is flush with the top elevation of the coarse aggregate asphalt;

[0008] Step 4: Pour fine aggregate asphalt on the inner side of the two baffles until it is flush with the top surface of the baffles, and backfill the second backfill soil on the outer side of the two baffles so that the top elevation of the second backfill soil is flush with the top surface of the baffles.

[0009] A further improvement of the curb-free asphalt pavement construction method of the present invention is that the baffle includes a stainless steel edge strip and a connecting piece;

[0010] When executing the above step 2, the connecting member is first connected to the roadbed, and then the stainless steel edge strip is connected to the connecting member.

[0011] A further improvement of the curb-free asphalt pavement construction method of the present invention is that the connecting piece comprises two angle steels.

[0012] When executing the above step 2, the two angle steels are arranged back to back, the horizontal plates of the two angle steels are fixed to the top of the roadbed, the vertical plates of the two angle steels are relatively close to form a clamping space, and then the stainless steel edge strips are inserted into the clamping space.

[0013] A further improvement of the curbstone-free asphalt pavement construction method of the present invention is that, when executing the above step 2, after the stainless steel edge strip is inserted into the clamping space, the stainless steel edge strip is plug-welded to the vertical plate of the angle steel.

[0014] A further improvement of the curbstone-free asphalt pavement construction method of the present invention is that, when executing the above step 3, pouring of coarse aggregate asphalt and the first backfilling of soil are simultaneously constructed.

[0015] A further improvement of the curbstone-free asphalt pavement construction method of the present invention is that, when executing the above step 4, pouring of fine aggregate asphalt and second backfilling are carried out simultaneously.

[0016] A further improvement of the curbstone-free asphalt pavement construction method of the present invention is that, when performing the above step 4, when pouring the fine aggregate asphalt, a slope is provided from the middle to both sides.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. The use of baffles instead of traditional curb stones greatly reduces construction costs and inspection fees, and speeds up construction.

[0019] 2. Due to the thin structural characteristics of the baffle itself, the overall visual effect is more beautiful after the asphalt pavement construction is completed. You can see that the pavement and plants are seamlessly connected and coexist harmoniously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] The curb-free asphalt pavement construction method of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] See also Figure 1 to Figure 4 As shown, the method for constructing a curb-free asphalt pavement comprises the following steps:

[0029] Step 1: construct a roadbed 1 at the designed position of the asphalt pavement, so that the top surface of the roadbed 1 is flush with the top surface of the planting soil 2 of the green belts on both sides;

[0030] Step 2: Connect baffles 3 on both sides of the planting soil 2 of the green belts on both sides at the top of the roadbed 1, so that the baffles 3 are arranged along the length direction of the roadbed 1, and the top elevation of the baffles 3 is flush with the top design elevation of the asphalt pavement;

[0031] Step 3: pouring coarse aggregate asphalt 4 on the inner side of the two baffles 3 until the designed position, backfilling the first backfill soil 5 on the outer side of the two baffles 3, so that the top elevation of the first backfill soil 5 is flush with the top elevation of the coarse aggregate asphalt 4;

[0032] Step 4: Pour fine aggregate asphalt 6 on the inner side of the two baffles 3 until it is flush with the top surface of the baffles 3, and backfill the second backfill soil 7 on the outer side of the two baffles 3 so that the top elevation of the second backfill soil 7 is flush with the top surface of the baffles 3.

[0033] Preferably, the baffle 3 includes a stainless steel edge strip 301 and a connecting piece;

[0034] When executing the above step 2, the connecting member is first connected to the roadbed 1, and then the stainless steel edge strip 301 is connected to the connecting member.

[0035] Specifically, the thickness of the stainless steel edge strip 301 is between 5 mm and 8 mm.

[0036] By setting the stainless steel edge strip 301 instead of the traditional curb stone, the stainless steel itself has strong corrosion resistance and durability, which can meet the future maintenance and care of the road surface. Moreover, due to the thin characteristics of the stainless steel edge strip 301 itself, the overall visual effect is more beautiful after the asphalt pavement construction is completed. It can be seen that the asphalt pavement and plants are seamlessly connected and coexist harmoniously.

[0037] Specifically, the stainless steel edge strip 301 includes a plurality of stainless steel plate units, and the plurality of stainless steel plate units are welded to each other.

[0038] Since the asphalt pavement is long, it is obviously impossible to prefabricate and transport stainless steel edge strips 301 of the same length, so a plurality of stainless steel plate units are welded to each other to form the stainless steel edge strips 301 .

[0039] Preferably, the connecting piece includes two angle steels 302,

[0040] When executing the above step 2, the two angle steels 302 are arranged back to back, the horizontal plates of the two angle steels 302 are fixed to the top of the roadbed 1, the vertical plates of the two angle steels 302 are relatively close to form a clamping space, and then the stainless steel edge strip 301 is inserted into the clamping space.

[0041] Specifically, the angle steel 302 is arranged along the length direction of the roadbed 1 .

[0042] Specifically, the transverse plate of the angle steel 302 is connected to the roadbed 1 via screws 303 , and a through hole is provided on the transverse plate of the angle steel 302 for the screws 303 to pass through and be driven into the roadbed 1 .

[0043] Preferably, when performing the above step 2, after the stainless steel side bar 301 is inserted into the clamping space, the stainless steel side bar 301 is plug-welded to the vertical plate of the angle steel 302 .

[0044] The stainless steel side strip 301 is first inserted into the clamping space, and then plug-welded by argon arc welding, thereby improving the connection stability of the stainless steel side strip 301.

[0045] Traditional curb stone construction requires excavation on both sides of the roadbed 1, and then setting multiple curb stones on both sides of the roadbed 1. After installation, it is necessary to check whether the top elevations of the multiple curb stones are flush, which takes up construction time. However, the present application improves construction efficiency by setting connecting parts and stainless steel edge strips 301, and there is no need to check the top elevation.

[0046] Preferably, when executing the above step 3, pouring of the coarse aggregate asphalt 4 and the first backfill soil 5 are constructed simultaneously.

[0047] Preferably, when executing the above step 4, pouring of fine aggregate asphalt 6 and second backfill soil 7 are carried out simultaneously.

[0048] By simultaneously pouring the coarse aggregate asphalt 4 and the first backfill 5, and simultaneously pouring the fine aggregate asphalt 6 and the second backfill 7, it is ensured that the forces on both sides of the baffle 3 are uniform, thus preventing the baffle 3 from overturning.

[0049] Preferably, when performing the above step 4, when pouring the fine aggregate asphalt 6, the slope is lowered from the middle to both sides.

[0050] Specifically, the slope is controlled between 1% and 2%.

[0051] By sloping from the middle to both sides when pouring the fine aggregate asphalt 6, the drainage effect of the asphalt pavement is ensured. When it rains, rainwater automatically drains from the asphalt pavement to both sides.
