Detailed Description

As shown in fig. 1-3, a concrete pouring road comprises a sand stone layer 1 and a concrete pouring layer 2, wherein the top surface of the concrete pouring layer 2 is obliquely arranged towards one side of the direction in which the width of the concrete pouring layer is located, vertical piles 3 with uniform intervals are buried in the concrete pouring layer 2 along the length direction of the road, transverse extension parts 31 are arranged on the vertical piles 3 along the width direction of the road, and the bottoms of the vertical piles 3 extend into the sand stone layer 1. This concrete pouring road is by the grit layer 1 bottoming, then pours concrete on the grit layer 1 and forms concrete placement layer 2, and this application buries upright pile 3 in advance in concrete placement layer 2 position department, then pours into concrete again and forms concrete placement layer 2, and upright pile 3 can form the support to concrete placement layer 2, makes it be difficult for subsidence or fracture, and structural strength obtains improving. Moreover, the vertical pile 3 has the extension part 31 in the width direction of the road, the length of the extension part 31 is basically the same as the width of the road, and thus the vertical pile can be supported by the concrete pouring layer 2 along the width direction of the concrete pouring layer 2, and even if a vehicle passes through the edge of the concrete pouring layer 2, the vertical pile cannot be broken and collapsed, so that the structural strength of the vertical pile is further improved.

A pouring groove 21 is formed in the lower side of the concrete pouring layer 2 along the length direction of the road, and a drainage channel 4 formed by pouring integrally is arranged in the pouring groove 21. The top surface of the concrete placement layer 2 of this application is the slope setting so can conveniently drain, just pour out a pouring groove 21 in its lower one side when pouring concrete placement layer 2, this pouring groove 21 is not used for direct drainage, we pour out water drainage canal 4 through independent, then put into pouring groove 21 with water drainage canal 4, water on the concrete placement layer 2 can follow the inclined plane and flow down in water drainage canal 4 and drain away, the design of independent water drainage canal 4 is in order to prevent that concrete placement layer 2 from taking place the fault in water drainage canal 4 department or collapsing and leading to water drainage canal 4 local fracture to lead to rivers to be unsmooth, the problem of drainage is designed into independent water drainage canal 4 and is broken and collapsed even pouring groove 21 department, water drainage canal 4 also can normally communicate the drainage, the structural strength of water drainage canal 4 is promoted so designed. The cross section of the drainage canal 4 is concave, and the drainage canal comprises a cement bottom plate 41 and cement side plates 42 positioned on two sides of the cement bottom plate 41, wherein the cement bottom plate 41 and the two cement side plates 42 are integrally formed through pouring, and a water passing channel 43 is formed between the cement bottom plate 41 and the two cement side plates 42. The lowest position of the concrete placement layer 2 is slightly higher than or flush with the top surface of the cement side plate 42 on the side of the drain channel 4 adjacent to the concrete placement layer 2. The top surface of the side of the water drainage channel 4, which is close to the concrete pouring layer 2, is flush with the lowest part of the concrete pouring layer 2, so that water flowing down from the concrete pouring layer 2 can directly enter the water channel 43 on the water drainage channel 4 to be discharged, no water accumulation is generated, the water drainage channel is quite practical, even if the local concrete pouring layer 2 breaks and collapses, the local position is just disconnected with the water drainage channel 4, water at the position can directly enter the pouring groove 21 to be discharged, and other road surfaces are normally drained due to normal communication of the water drainage channel 4, so that the design connection strength is high, and the stability is very good.

The bottom of the extension 31 is placed against the top of the sand layer 1. The upright pile 3 is actually formed by adopting steel bars to punch a columnar frame and then adopting concrete casting, and the extension part 31 on the upright pile is also formed by adopting a square strip-shaped structure of the steel bars to punch and then adopting concrete casting, and the extension part 31 is attached to the ground and directly contacted with the sand stone layer 1, so that the weight of the concrete casting layer 2 can be better supported, and the integral structural strength of the upright pile is further improved. The distance between two adjacent stakes 3 is ten meters. Every ten meters, the whole road can be supported by the upright posts at uniform intervals, so that the bearing capacity of the road is greatly improved, and the road has better structural strength. The top surface of the concrete placement layer 2 is inclined at an inclination angle α of 3 degrees toward one side of the direction in which the width thereof is located. The inclination angle of 3 degrees makes the road sense of inclination of the whole road surface not very strong, and normal vehicles can not feel inclination when driving on the road surface, but rainwater can well enter into the drainage canal 4 along the inclination direction to drain when raining.
