Frost heaving and seepage preventing structure of filled channel
The invention relates to the field of water conservancy projects, and discloses a fill channel frost heaving and seepage preventing structure which is sequentially provided with a concrete lining layer, a waterproof layer, a heat preservation layer, a drainage layer and a sand cushion layer from top to bottom. An expansion joint structure is adopted in the splicing position of the two concrete prefabricated parts, a rubber water stop belt is arranged at the expansion joint structure, the concrete prefabricated parts are formed by splicing and connecting a plurality of concrete prefabricated blocks into a whole through a preset joint structure, and the joint structure is filled with structural waterproof glue. A multi-protection system is formed through the waterproof layer, the drainage layer, the drainage pipe, the ventilation pipe and other structures, water exchange between the lining structure and foundation soil can be effectively isolated, the water content and the frost heaving rate of the foundation soil are reduced, redundant water in the foundation soil and the structure is discharged in time, and therefore leakage and frost heaving damage of a filling channel are effectively prevented.
本申请涉及水利工程领域，公开了一种填方渠道抗冻胀防渗结构，所述抗冻胀防渗结构从上至下依次设置的混凝土衬砌层、防水层、保温层、排水层和砂垫层，所述混凝土衬砌层由断面为弧底梯形的混凝土预制件拼接而成，且两个混凝土预制件拼接处采用伸缩缝结构，并在伸缩缝结构处设置橡胶止水带，所述混凝土预制件由多个混凝土预制块以预先设置的接缝结构拼接连成一体，且接缝结构处填充有结构防水胶。通过防水层、排水层、排水管、通气管等结构形成了一个多重防护体系，可以有效地隔断衬砌结构与基土之间的水分交换，减少基土的含水量和冻胀率，并及时将基土与结构中的多余水分排出，从而有效地防止填方渠道的渗漏和冻胀破坏。
