Description

Technical Field

[0001] The utility model relates to the technical field of plastic drainage boards, in particular to a multi-channel plastic drainage board. Background Art

[0002] The plastic drainage board is made of polystyrene or polyethylene as the raw material, and the plastic bottom plate is stamped into conical protrusions or convex points with stiffening ribs. Through continuous innovation and research and development, the raw materials have been greatly improved and changed. Now it is made of polyvinyl chloride by pressing, and the compressive strength and overall flatness have been greatly improved. The plastic drainage board and the porous drain pipe form an effective drainage system, which is a widely used building tool.

[0003] The existing plastic drainage board has the following disadvantages when in use: when the existing plastic drainage board is in use, a geotextile is directly laid on the top, and the infiltrated rainwater is discharged from the drainage grooves on the surface of the drainage board. However, the existing drainage board generally has a single-channel drainage groove structure, and the top of the convex block structure on the surface is directly attached to the surface of the geotextile and is a sealed structure, which will cause the moisture at the contact position with the convex block to be unable to be directly discharged, affecting the drainage efficiency of the drainage board. For this reason, we propose a multi-channel plastic drainage board. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a multi-channel plastic drainage board. By improving the drainage board body and adopting a double-channel structure for water discharge, the drainage efficiency of the drainage board is improved, and the problems in the background art can be effectively solved.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A multi-channel plastic drainage board, including a drainage board body, further including a drainage mechanism. The drainage mechanism is arranged inside the drainage board body. The drainage mechanism includes convex blocks, water seepage holes, main drainage grooves, a support plate, hollow columns, side drainage holes and discharge grooves. Convex blocks are integrally formed on the top of the drainage board body, and water seepage holes are opened at the tops of the convex blocks. Main drainage grooves are opened at positions between the convex blocks on the surface of the drainage board body. A support plate is inserted at the bottom of the drainage board body, and hollow columns corresponding to the positions of the convex blocks are integrally formed on the surface of the support plate. The tops of the hollow columns all abut against the inner surfaces of the convex blocks. Side drainage holes are opened at positions near the support plate at the bottoms of the hollow columns. Discharge grooves are opened on both sides of the surface of the drainage board body.

[0007] Further, it further includes a connecting mechanism. A connecting mechanism is provided between the drainage board main body and the supporting plate. The connecting mechanism includes a slot and an inserting strip. Slots are opened at the bottom side positions of the drainage board main body, and inserting strips inserted into the slots are integrally formed at the peripheral positions of the top of the supporting plate; slots are opened at the bottom peripheral positions of the drainage board main body, and inserting strip structures are provided at the peripheral positions of the top of the supporting plate. When docking the supporting plate and the drainage board main body, the hollow pillars at the top of the supporting plate are inserted against the bottom of the convex block while the inserting strip structures are inserted against the slots and inserted. After being inserted in place, the inserting strips are completely inserted into the slots, ensuring the fitting between the drainage board main body and the supporting plate and improving the sealing performance of the connection part.

[0008] Further, auxiliary drainage grooves are opened at the positions between the hollow pillars on the surface of the supporting plate, and the ends of the auxiliary drainage grooves are all communicated with the surface of the discharge groove; the water seeping out from the side discharge holes will fall into the auxiliary drainage grooves and be discharged from the discharge groove along the auxiliary drainage grooves.

[0009] Further, a geotextile is laid on the surface of the drainage board main body; after the geotextile is laid, it plays a role of filtering and blocking, preventing soil from falling on the surface of the drainage board main body.

[0010] Further, rubber pads are bonded to the inner wall positions of the slots, and the rubber pads are located at the connection between the inserting strips and the slots; the rubber pad structure at the connection can improve the sealing performance of the connection part and the docking fitting effect of the connection part after docking.

[0011] Compared with the prior art, the utility model has the following beneficial effects: The surface of the drainage board main body is provided with a convex block structure. The water directly infiltrated through the geotextile will fall on the surface of the drainage board main body and be discharged along the main drainage groove. A supporting plate structure is inserted at the bottom of the drainage board main body. After the supporting plate structure is installed in place, the hollow pillars at its top are inserted into the convex blocks, which can strengthen the structure of the convex blocks. At the same time, water seepage holes are provided at the top of the convex blocks, and the water at the position in contact with the top of the convex blocks will directly infiltrate and be discharged into the hollow pillars through the water seepage holes, slide down to the bottom along the hollow pillars and then be discharged from the side discharge holes into the auxiliary drainage grooves, and finally be discharged from the discharge groove position. Cooperating with the main drainage groove, a dual-channel drainage structure is formed. Compared with the existing drainage board structure, the structural strength of the convex blocks is greatly improved, and the drainage efficiency of the drainage board is enhanced; Slots are opened at the bottom peripheral positions of the drainage board main body, and inserting strip structures are provided at the peripheral positions of the top of the supporting plate. When docking the supporting plate and the drainage board main body, the hollow pillars at the top of the supporting plate are inserted against the bottom of the convex block while the inserting strip structures are inserted against the slots and inserted. After being inserted in place, the inserting strips are completely inserted into the slots, ensuring the fitting between the drainage board main body and the supporting plate and improving the sealing performance of the connection part.
