Waterproof construction method for pipe gallery structure
The invention discloses a waterproof construction method for a pipe gallery structure, and relates to the technical field of comprehensive pipe gallery construction, and the waterproof construction method comprises the following steps: S1, waterproof construction of a foundation pit bottom plate; s2, pipe gallery bottom plate self-waterproof construction; c40 waterproof concrete is adopted for pipe gallery bottom plate pouring, and in the C40 waterproof concrete, the water-binder ratio is not larger than 0.45, the alkali content is not larger than 3 kg/m < 3 >, and the chloride ion content is not larger than 0.2%; s3, waterproof construction of a pipe gallery bottom plate; s4, waterproof construction of the side wall of the pipe gallery; s5, waterproof construction of the pipe gallery top plate; s6, node composite waterproof construction; a rubber water-stop belt is embedded in the deformation joint, a self-adhesive waterproof roll with the thickness of 2 mm is arranged on the upstream face of the deformation joint, and the joint on the inner side of the structure is subjected to caulking through double-component polysulfide sealant; the through-wall pipe needs to be embedded before concrete is poured, and a water stop ring is additionally arranged; when the number of the through-wall pipelines is large, the through-wall box is adopted, the sealing steel plate of the box is firmly welded with the embedded part on the wall, and the sealing material is injected from the pouring hole in the steel plate, so that the pipelines can be prevented from being eroded and permeated, and the safe operation and the service life of the pipelines are guaranteed.
本发明公开了一种管廊结构防水施工方法，涉及综合管廊施工技术领域，包括步骤：S1基坑底板防水施工；S2管廊底板自防水施工；采用C40防水混凝土进行管廊底板浇筑，其中，所述C40防水混凝土中，水胶比不大于0.45，含碱量不大于3kg/m3，氯离子含量不大于0.2％；S3管廊底板防水施工；S4管廊侧墙防水施工；S5管廊顶板防水施工；S6节点复合防水施工；变形缝中埋设橡胶止水带，变形缝的迎水面设置2mm厚自粘性防水卷材，并在结构内侧的缝内用双组份聚硫密封膏嵌缝；穿墙管应在浇注混凝土前埋设，并加止水环；穿墙管线较多时，采用穿墙盒，盒的封口钢板与墙上预埋件焊牢，并从钢板上的浇注孔注入密封材料，能够防止管线被侵蚀和渗透，保障管线的安全运行和使用寿命。
