Casing pipe structure suitable for water conveying pipe to penetrate through important structures
The invention relates to the technical field of water pipe construction, in particular to a sleeve structure suitable for a water pipe to penetrate through important structures, which comprises an outer sleeve and a plurality of inner pipes slidably arranged in the outer sleeve in a penetrating manner, anti-corrosion layers are arranged on the outer side walls of the inner pipes, a plurality of pulleys are rotatably arranged on the outer walls of the inner pipes, and the pulleys abut against the inner wall of the outer sleeve in a rolling manner. A pouring cavity is formed between the inner pipe and the outer sleeve, a plurality of grouting holes communicating with the pouring cavity are formed in the inner pipe, and self-compacting concrete is poured into the grouting holes through an external concrete pouring machine. The pulleys are arranged, the inner pipe slides in the outer sleeve, the inner pipe is prevented from making direct contact with the outer sleeve under supporting of the pulleys, then the anti-corrosion layer is prevented from being abraded, and therefore the beneficial effect that the service life of the water conveying pipe is prolonged is achieved.
本申请涉及一种适用于输水管穿越重要构筑物的套管结构，涉及输水管道施工技术领域，包括外套管、若干滑动穿设于外套管内的内管，内管的外侧壁上设有防锈蚀层，内管的外壁上转动设置有若干滑轮，滑轮滚动抵接于外套管的内壁，内管和外套管之间形成有浇筑腔，内管上开设有若干连通浇筑腔的注浆孔，注浆孔供外部混凝土灌注机灌入自密实混凝土。本申请通过设置滑轮，利用内管滑移于外套管内，在滑轮的支撑下避免内管和外套管直接接触，进而避免防锈蚀层受到磨损，从而具有增加输水管使用寿命的优点。
