Backfilling structure of small-caliber steel corrugated pipe culvert and construction method
The invention discloses a backfilling structure of a small-caliber steel corrugated pipe culvert and a construction method. In the backfilling structure, a corrugated pipe 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 corrugated pipe and the inner wall of the foundation pit is filled with a flow-state self-compacting quick-setting pouring medium. After the steel corrugated pipe culvert is placed in the foundation pit, a flow-state self-compacting rapid-hardening pouring medium is injected from one side of the steel corrugated pipe culvert, and when the gap between the steel corrugated pipe culvert 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 steel corrugated pipe culvert in batches till the outer surface of the steel corrugated pipe culvert 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 steel corrugated pipe are subjected to dense backfill, and the excellent performance of the steel corrugated pipe culvert can be fully exerted.
本发明公开了一种小口径钢制波纹管涵洞的回填结构及施工方法，该种回填结构中波纹管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；波纹管与基坑内壁之间填充流态自密实速凝灌注介质。当钢波纹管涵洞置入基坑内后，由钢波纹管涵洞一侧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钢波纹管涵洞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钢波纹管涵洞两侧分次浇注，直至流态自密实速凝灌注介质将钢波纹管涵洞外表面完全包覆。该种回填结构及施工方法将钢制波纹管周围的所有部位进行了密实回填，能够能充分发挥钢波纹管涵洞的优越性能。
