Fig. 1 to 4 show an embodiment of the present utility model.

Example 1:

As shown in fig. 1-3, an asphalt pavement assembled base layer comprises a base layer body 1, wherein a drain pipe 2 is horizontally arranged in the middle of the base layer body 1, two ends of the drain pipe 2 are respectively communicated with two ends of the base layer body 1, and when two adjacent base layer bodies 1 are connected, the drain pipes 2 of the two base layer bodies 1 are aligned and communicated; the upper portion of basic unit body 1 sets up to permeable layer 3, and the surface of drain pipe 2 upside is provided with the wash port 4 that link up inside and outside both sides, and permeable layer 3's downside and wash port 4 laminate mutually. By providing the drain pipe 2 and the permeable layer 3, the accumulated water on the road surface can be guided into the drain pipe 2 through the permeable layer 3 and then discharged into the sewage well through the drain pipe 2. A plurality of base course bodies 1 are installed in a continuous arrangement at the roadside, and rainwater can be systematically guided into the sewage well by communicating the drain pipes 2 of the respective base course bodies 1. By providing the drain hole 4, water passing through the water permeable layer 3 can be facilitated to enter the drain pipe 2.

One end of the base body 1 is convexly provided with a flange 5 around the drain pipe 2, and the other end is concavely provided with a groove 6 matched with the flange 5 around the drain pipe 2. Through setting up flange 5 and recess 6, can be when installing basic unit's 1, can make the drain pipe 2 intercommunication of two adjacent basic unit's 1 through the installation of registering flange 5 and recess 6, avoid the condition emergence of drain pipe 2 dislocation. And simultaneously, the joint of the two base layer bodies 1 can be leveled.

The inner diameter of the drain pipe 2 at one end of the flange 5 is enlarged to form a connecting end 7, and the surfaces of the connecting end 7 and the flange 5 are flush; the drain pipe 2 protrudes from the bottom of the groove 6 at one end of the groove 6 to form an insertion section 8; the outer diameter of the insertion section 8 matches the inner diameter of the connection end 7. By providing the connection end 7 and the insertion section 8, the stability of the connection of the drain pipe 2 is further improved.

Example 2:

On the basis of the embodiment 1, as shown in fig. 3 and 4, a cleaning hole 9 communicated with the drain pipe 2 is arranged on the upper side of the base layer body 1, and a plugging plug 10 for plugging the cleaning hole 9 is detachably arranged at the upper end of the cleaning hole 9. Because rainwater or sewage permeates into the drain pipe 2 through the permeable layer 3, the rainwater or sewage can more or less carry dust and soil and the like, and the dust and soil can not be completely discharged along with the drain pipe 2 when flowing through the drain pipe 2 along with the rainwater, and can more or less accumulate in the drain pipe 2, so that the drain pipe 2 is blocked to a certain extent, and at the moment, sanitation workers are required to clean the drain pipe 2 through a high-pressure water gun. The drain pipe 2 is cleaned by taking out the sealing plug 10 from the drain hole 4, aligning the muzzle of the high-pressure water gun with the cleaning hole 9, opening a water valve, and flushing the sludge accumulated in the drain pipe 2 into the sewage well by utilizing the high-pressure water flow of the high-pressure water gun to reenter the drain pipe 2.

The sealing plug 10 is detachably arranged in the cleaning hole 9 through a mounting ring 11, and the outer wall of the mounting ring 11 is connected with the hole wall of the cleaning hole 9; when the seal plug 10 is installed in the cleaning hole 9, the lower end of the seal plug 10 is attached to the upper side of the mounting ring 11. By arranging the mounting ring 11, the plug 10 can be conveniently mounted in the cleaning hole 9.

The upper side of the closure plug 10 is provided with a disassembly hole 12 for connecting an external disassembly tool; the wall of the disassembly hole 12 is provided with a disassembly groove 13. Through setting up the dismantlement hole 12, can be convenient for connect external connection instrument to the sanitation worker of being convenient for dismantles the shutoff plug 10 from the clearance hole 9 in. The outside clearance instrument includes connecting rod 15, fixture block 16 and pull ring 17, and pull ring 17 sets up in the tip of connecting rod 15, and fixture block 16 sets up in the side of connecting rod 15 one end of keeping away from pull ring 17. When the sealing plug 10 needs to be detached from the cleaning hole 9, the sealing plug 10 is detached from the cleaning hole 9 by inserting the connecting rod 15 into the detaching hole 12, then clamping the clamping block 16 on the connecting rod 15 into the detaching groove 13, and then pulling the pull ring 17.

The side of the base body 1 is provided with a pouring connection groove 14. By arranging the pouring connecting groove 14, the concrete base layer can be conveniently connected with the concrete base layer in the middle of the pavement, and cracks are avoided. The construction method comprises the following steps: before constructing a concrete base layer in the middle of a pavement, the base layer body 1 is firstly arranged at the edge of the pavement according to the planned pavement width. And after the installation is finished, concrete is poured in the middle of the pavement to serve as a concrete base layer of the pavement. The concrete base layer and the base layer body 1 are better connected together by the concrete flowing into the pouring connecting grooves 14. When the asphalt pavement is poured, water permeable asphalt is poured on the upper side of the base layer body 1, so that rainwater or sewage can conveniently permeate into the drain pipe 2.
