Backfilling structure for pipeline construction and construction method
The invention discloses a backfilling structure for pipeline construction and a construction method. In the backfilling structure, a pipeline is laid at the bottom of a foundation pit formed in the surface of a compacted roadbed; the pit bottom of the foundation pit is an arc-shaped surface; and the space between the pipeline and the inner wall of the foundation pit is filled with a flow-state self-compacting rapid-hardening pouring medium After the pipeline is placed in the foundation pit, a flow-state self-compacting rapid-hardening pouring medium is injected into the bottom of the pipeline, and when the gap between the bottom of the pipeline and the bottom of the foundation pit is completely filled with the flow-state self-compacting rapid-hardening pouring medium, first pouring is stopped; and after the medium is solidified, the flow-state self-compacting rapid-hardening pouring medium is poured from the two sides of the pipeline for several times till the outer surface of the pipeline is completely wrapped by the flow-state self-compacting rapid-hardening pouring medium. According to the backfill structure and the construction method, all parts around the pipeline are subjected to dense backfill, and the excellent performance of the pipeline culvert can be fully exerted.
本发明公开了一种管道施工的回填结构及施工方法，该种回填结构中管道铺设在开设于夯实路基表面的基坑坑底；基坑的坑底为弧形面；管道与基坑内壁之间填充流态自密实速凝灌注介质。当管道置入基坑内后，向管道底部注入流态自密实速凝灌注介质，当流态自密实速凝灌注介质将管道底部和基坑坑底之间的间隙完全填充时，停止第一次浇注；待介质凝固后，再将流态自密实速凝灌注介质由管道两侧分次浇注，直至流态自密实速凝灌注介质将管道外表面完全包覆。该种回填结构及施工方法将管道周围的所有部位进行了密实回填，能够能充分发挥管道涵洞的优越性能。
