上马村橡胶坝基础底板和防渗排水设计初步分析

摘要

橡胶坝是用高强力合成纤维织物做受力骨架，内外涂敷合成橡胶作黏结保护层，加工成胶布，按要求的尺寸，锚固在混凝土基础底板上，成封闭袋形，用水、气或水气混合充胀，形成挡水坝。不需要挡水时，泄空坝袋内的水（气），便可恢复原有河渠的过流断面。文章对基础底板和防渗排水设计做了初步分析。%Rubber dam takes high strength synthetic fiber fabric as the bearing frame,internal and external synthetic rubber adhesive protection layer is coated and processed into fabric,according to the required size,then anchored in the concrete foundation slab.Water,gas or gas mixture is inflated to form a dam.When it is not necessary to block water,empty the dam bag in the water (gas),flow section can restore the original canal.This paper made a preliminary analysis of the foundation and the seepage con-trol design of rubber dam.
