In actual engineering construction, it is usually necessary to consolidate soft soil foundations, and the most commonly used method is drainage consolidation method, which consists of a drainage system and a loading system. The drainage system includes a vertical drainage body and a horizontal drainage body, and the typical vertical drainage body is a plastic drainage board.

塑料排水板通常由塑料芯板和包裹在塑料芯板四周的透水无纺布组成。塑料芯板大多采用聚乙烯材料,是排水板的骨架和排水通道。滤膜通常采用无纺布制成,紧贴塑料芯板包裹。在施工时,将塑料排水板通过插板机插入软土地基中。当地基表面加载时,软土地基中产生超孔隙水压力,地下水受压力差驱动透过外层滤膜经塑料芯板上的排水通道排到上部水平排水体,再从其他地方排出,从而实现加速软土固结的目的。The plastic drainage board is usually composed of a plastic core board and a permeable non-woven fabric wrapped around the plastic core board. The plastic core board is mostly made of polyethylene material, which is the skeleton and drainage channel of the drainage board. The filter membrane is usually made of non-woven fabric and wrapped tightly against the plastic core board. During construction, the plastic drainage board is inserted into the soft soil foundation through the inserter. When the ground surface is loaded, excess pore water pressure is generated in the soft soil foundation, and the groundwater is driven by the pressure difference to pass through the outer filter membrane through the drainage channel on the plastic core board to be discharged to the upper horizontal drainage body, and then discharged from other places, so as to realize The purpose of accelerating the consolidation of soft soil.

但排水板在向上排水的过程中,土体中的部分细颗粒会通过外层滤膜进入芯板。这些颗粒粒径很小,颗粒间有很强的静电作用,易形成絮凝状或蜂窝状的结构形式,从而会在芯板逐渐积累造成一些排水通道的淤堵,影响排水板的排水效率。因此,需要一种经济有效的措施来解决由于排水通道淤堵造成排水能力下降的问题。However, during the upward drainage of the drainage board, some fine particles in the soil will enter the core board through the outer filter membrane. The particle size of these particles is very small, and there is a strong electrostatic effect between the particles, which is easy to form a flocculation or honeycomb structure, which will gradually accumulate in the core board, causing some drainage channels to block, affecting the drainage efficiency of the drainage board. Therefore, there is a need for a cost-effective measure to solve the problem of reduced drainage capacity due to clogging of drainage channels.

具体实施方式Detailed ways

下面将结合附图对本实用新型做详细的介绍:如附图1、2所示,本实用新型包括排水芯板件1、滤膜2,排水芯板件1制作所采用的材质为PVC材料,排水芯板件1的横截面为格栅状的截面,并形成有若干竖向排水通道3;排水芯板件1的底部套接有连通板靴4,且连通板靴4的四周与若干排水通道3均连通;滤膜2包裹在排水芯板件1的四周及连通板靴4的四周和底部,且若干排水通道3均与滤膜2相通;当软土中的细小颗粒透过滤膜2在排水芯板件1上积累,造成部分排水通道3无法向上排水时,淤堵通道内的水可向下汇入连通板靴4,然后从未发生淤堵的通道向上排出,从而增强排水芯板件1的排水能力。The present utility model will be described in detail below in conjunction with the accompanying drawings: as shown in the accompanying drawings 1 and 2, the utility model includes a drainage core board member 1 and a filter membrane 2, and the material used for the production of the drainage core board member 1 is PVC material, The cross section of the drainage core plate 1 is a grid-like section, and a number of vertical drainage channels 3 are formed; the bottom of the drainage core plate 1 is sleeved with a connecting shoe 4, and the surrounding of the connecting shoe 4 is connected with several drainage channels. The channels 3 are all connected; the filter membrane 2 is wrapped around the drainage core plate 1 and around and the bottom of the connected shoe 4, and several drainage channels 3 are all communicated with the filter membrane 2; when the fine particles in the soft soil penetrate the filter membrane 2 When some of the drainage channels 3 cannot be drained upward due to accumulation on the drainage core plate 1, the water in the blocked channel can flow downward into the connecting shoe 4, and then be discharged upward from the channel that has not been blocked, thereby enhancing the drainage core. Drainage capacity of panel 1.

连通板靴4为底部密封、顶部开口的PVC容器,且连通板靴4的横截面面积大于排水芯板件1的横截面面积;连通板靴4的高度为10至20cm,长度比排水芯板件1的横截面长度大2至4mm,宽度比排水芯板件1的横截面宽度大6至8mm,因排水通道3的渗入口均朝向连通板靴4的长边方向,只有两侧边的渗入口朝向连通板靴4的宽边方向,那么通过上述连通板靴4的宽度、长度与排水芯板件1之间的间隙设置,能使得排水通道内的水可以向下汇聚到连通板靴内,并使得各排水通道相互之间的水能快速的流通,排水效率大大提升。The connecting shoe 4 is a PVC container with a sealed bottom and an open top, and the cross-sectional area of the connecting shoe 4 is larger than that of the drainage core plate 1; The length of the cross section of the piece 1 is 2 to 4 mm larger, and the width is 6 to 8 mm larger than the width of the cross section of the drainage core board piece 1. Because the infiltration ports of the drainage channel 3 are all facing the long side of the connecting shoe 4, only the two sides are The infiltration port faces the broad side direction of the communication shoe 4, then through the setting of the gap between the width and length of the communication shoe 4 and the drainage core plate 1, the water in the drainage channel can be collected downward to the communication shoe and make the water between the drainage channels circulate quickly, and the drainage efficiency is greatly improved.

装置工作时,由于连通板靴4底部密封、顶部开口的结构,可以在排水芯板件1底部形成储水区域;各个排水通道3内的水可向下渗流汇入该储水区域,而储水区域内的水可选择沿程阻力较小的排水通道3向上排出;因此,当部分排水通道3发生淤堵无法向上排水时,这些排水通道3内的水可向下汇入连通板靴4中,然后从其他未发生淤堵的排水通道3流出到地表,从而增强排水芯板件1的排水能力。When the device is working, due to the structure of the bottom of the connecting shoe 4 being sealed and the top being open, a water storage area can be formed at the bottom of the drainage core plate 1; The water in the water area can be discharged upward through the drainage channel 3 with lower resistance along the way; therefore, when some drainage channels 3 are blocked and cannot be drained upward, the water in these drainage channels 3 can flow downward into the connecting shoe 4 , and then flow out to the surface from other drainage channels 3 that are not blocked, thereby enhancing the drainage capacity of the drainage core panel 1 .

排水芯板件1包括基板11和支撑板12,支撑板12固定在基板11的两侧,并沿基板11的长度方向依次排列;位于基板11两侧的支撑板12呈对称分布,且支撑板12与基板11呈垂直状分布;相邻的支撑板12与基板11之间构成“凵”字形排水通道3,只有两侧边胡排水通道3为L形开口状,且开口均朝向滤膜2侧,这样能顺利的将来自通过滤膜2的水渗入至排水通道3内。The drainage core plate 1 includes a base plate 11 and a support plate 12. The support plates 12 are fixed on both sides of the base plate 11 and are arranged in sequence along the length direction of the base plate 11; the support plates 12 located on both sides of the base plate 11 are symmetrically distributed, and the support plates 12 and the base plate 11 are distributed vertically; the adjacent support plates 12 and the base plate 11 form a "凵"-shaped drainage channel 3, and only the drainage channels 3 on both sides are L-shaped openings, and the openings are all towards the filter membrane 2 In this way, the water from passing through the filter membrane 2 can penetrate into the drainage channel 3 smoothly.

在经过一定时间的排水工作后,软土中的细颗粒将不可避免地透过滤膜2进入排水芯板件1中,在排水芯板件1上逐渐累积造成部分排水通道淤堵,无法向上排水;通过本设计的排水板装置,使这些排水通道3内的水可以向下汇聚到连通板靴4内,然后从未发生淤堵的排水通道3向上排出,从而增强排水芯板件1的排水能力,保证排水过程的长期有效性。After a certain period of drainage work, the fine particles in the soft soil will inevitably penetrate the filter membrane 2 into the drainage core board 1, and gradually accumulate on the drainage core board 1, causing some drainage channels to be blocked and unable to drain upwards. ; Through the drainage plate device of this design, the water in these drainage channels 3 can be collected downward into the connecting plate shoe 4, and then the drainage channel 3 that has never been blocked is discharged upward, thereby enhancing the drainage of the drainage core plate 1. ability to ensure the long-term effectiveness of the drainage process.

本实用新型不局限于上述实施方式,不论在其形状或材料构成上作任何变化,凡是采用本实用新型所提供的结构设计,都是本实用新型的一种变形,均应认为在本实用新型保护范围之内。The present utility model is not limited to the above-mentioned embodiments, and no matter what changes are made in its shape or material composition, any structural design provided by the present utility model is a deformation of the present utility model, and should be considered in the present utility model. within the scope of protection.
