Abstract

The anti-scouring method of bridge piles has not been the best prevention and control method. Under the intensive research of the inventor, a method of backfilling anti-scouring with flexible composite bagged sand has been invented, which has a good effect in preventing and controlling the scour of bridge piles. The anti-scouring method for backfilling sand in flexible composite bags provided by this application is positioned by laying boats and flat barges; laying sand bags, wherein the design of the sand bags is selected from the mother and child bags, and the upper and lower layers are staggered through overlapping between the sand bags to ensure The tight connection between the sand bags and the filling of sand bags have been implemented to realize the backfilling of flexible composite bagged sand, so that the bridge piles can withstand two daily tidal erosion without being affected, effectively solving the problem of bridge pile anti-scouring.

Description

technical field

[0001] The invention relates to the technical field of anti-scour of bridge piles, and more particularly to a method for backfilling and anti-scour of flexible composite bagged sand. Background technique

[0002] The pipeline bridge project is one of the important infrastructure projects in the Yangkou port area, and it is an important support for the landing of LNG oil and the entry and exit of other liquid chemical materials. The project is located on the west side of the Yellow Sea Bridge. The main bridge is parallel to the Yellow Sea Bridge, with a center-to-center distance of 230m. There are approach bridges at both ends connected to the shore and island approach embankments. The total length of the bridge is 10763m, and the standard bridge width is 13m.

[0003] The upper pipe gallery belt of the bridge is a simply supported beam structure, the bored pile foundation section of the maintenance and fire passage is a structural simply supported-bridge dec...
