Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of civil engineering materials, in particular to a plastic drainage board capable of reducing blockage. Background Art
[0002] Plastic drain boards are used for soft soil foundation treatment and belong to the vertical drainage fixing method. The working principle of plastic drain boards is to increase the vertical drainage path of the soil layer, shorten the drainage distance, and accelerate the solidification of the foundation. The existing plastic drain boards include a plastic core board in the middle and a filter membrane surrounding the plastic core board. The end faces of common plastic core boards are parallel crosses, which are divided into two layers of several drainage channels arranged side by side; the process flow of plastic drain pipes is to level the ground → spread the lower sand cushion layer → put the machine in place → put on the plastic drain board → insert the casing → pull out the casing → cut off the plastic drain board → shift the machine → spread the upper sand cushion layer. During the construction process, it is easy for debris to enter the drainage channel. These debris will block the drainage channel, making the drainage channel below the debris unable to be used for drainage, reducing the drainage efficiency of the plastic drain board.

[0024] Compared with the prior art, the utility model is provided with gap A 2211 and gap B 2221 for horizontal communication on the core plate 2; when a drainage channel is blocked, the interstitial water can flow horizontally through the gap A 2211 and gap B 2221 and be discharged upward with the help of adjacent drainage pipes; and the gap A 2211 and gap B 2221 are staggered, which can not only divert the interstitial water entering the drainage channel and flowing upward, so that the interstitial water is evenly distributed in all unblocked drainage channels to ensure drainage efficiency, but also collide with debris in the interstitial water, so that the sand and gravel in the debris can be decomposed, reducing the probability of blockage.
[0025] The length of gap A 2211 is comparable to that of gap B 2221, so that the speed at which interstitial water passes through gap A 2211 and gap B 2221 is comparable, and the interstitial water can be more evenly distributed to all unblocked drainage channels.
[0026] The partitions are symmetrically arranged relative to the connecting plate 21 to stably support the filter membrane 1 and improve its anti-deformation capability.
[0027] The partition also includes a plate C 223 ; the plate C 223 is arranged on both sides of the connecting plate 21 , and the end faces are aligned with the end faces of the connecting plate 21 ; the plate C 223 can fully support the filter membrane 1 , and can reduce the possibility of cutting the filter membrane 1 .
[0028] The length of the diversion section A 2212 corresponds to the length of the gap B 2221; the length of the diversion section B 2222 corresponds to the length of the gap A 2211; in the drainage channel, the interstitial water can stably pass through the gap A 2211 or the gap B 2221.
[0029] The length of the diversion section A 2212 is greater than the length of the gap B 2221; the length of the diversion section B 2222 is greater than the length of the gap A 2211; there is a small drainage channel between the adjacent gaps A 2211 and gaps B 2221, which is neither connected to the gap A 2211 nor to the gap B 2221; the interstitial water can flow steadily in the small drainage channel to ensure the stable discharge of the interstitial water.
[0030] The diversion section A 2212 and the gap B 2221 have the same neutral plane; the diversion section B 2222 and the gap A 2211 have the same neutral plane; both ends of the plastic drainage board can be set upwards to increase construction convenience.
[0031] The working principle of this embodiment is as follows: gap A 2211 and gap B 2221 can connect adjacent drainage channels; when a drainage channel is blocked, interstitial water can flow laterally through gap A 2211 and gap B 2221 and be discharged upward with the help of adjacent drainage pipes; diversion section A 2212 and diversion section B 2222 divert the interstitial water entering the drainage channel and flowing upward, so that the interstitial water directly passes through gap A 2211 or gap B 2221 and is evenly distributed in all unblocked drainage channels to ensure drainage efficiency; the ends of diversion section A 2212 and the ends of diversion section B 2222 can collide with debris in the interstitial water, so that the gravel in the debris can be decomposed, reducing the probability of blockage.
[0032] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the similarities are not repeated here. The difference is that the core plate 2 is made of a mixture of polypropylene and polyethylene, and has the rigidity of polypropylene and the flexibility and weather resistance of polyethylene.
