Stamping reinforcement method of weak rolling area of roadbed and application thereof

Abstract

The invention provides a stamping reinforcement method of a weak rolling area of a roadbed and an application of the stamping reinforcement method of the weak rolling area of the roadbed. A high speed stamping reinforcement device-stamping rammer compactor is used, and a stamping pounder is lifted in a hydraulic or mechanical manner to punch a tamping plate with a buffer gasket for conducting stamping reinforcement on the weak rolling area of the roadbed which is normally rolled. An application of the stamping reinforcement method of the weak rolling area is further provided for the weak rolling area of the roadbed of a compact road rolled normally. Stamping reinforcement is carried out on junction of new and old roadbeds when the old road is widened, base of the roadbed newly widened, and newly filled roadbeds. Stamping reinforcement is carried out on a roadbed structure base and the weak rolling area of the roadbed of the compact railway rolled normally. Stamping reinforcement is carried out on water damage treatment of roadbeds of roads and railways. Stamping reinforcement is carried out on reinforcing the weak rolling area of river dams and brake back backfill water conservancy projects. The stamping reinforcement method of the weak rolling area of the roadbed provided by the invention has the beneficial effects that the backfill compactness of the weak rolling area of the roadbed is improved, the bearing capacity of the roadbed is improved, post-construction settlement of the weak rolling area is reduced, the project quality is effectively improved, the project expenses are saved, and the economical benefits are remarkable.

Description

technical field [0001] The invention relates to a stamping reinforcement method for a weakly rolled subgrade area and an application thereof, which are used for improving the compactness and bearing capacity of the subgrade weakly rolled area, and effectively reducing post-construction settlement of the weakly rolled subgrade area. Background technique [0002] With the current development of domestic high-grade road construction, higher requirements are put forward for the smoothness of the road surface and the overall integrity of the road surface. [0003] In some special areas of road subgrade filling and compaction operations: the overlapping parts of the road structure and the subgrade, the edge area of ​​rolling, and other narrow areas where the rolling work area is limited. Currently used large-scale compaction machines: road rollers, impact rollers, etc., are limited by structures and effective work areas, and cannot fully function; existing small-scale compaction e...

AI Technical Summary

Problems solved by technology

[0011] The use of new backfill materials greatly increases the cost of backfilling, and the above-mentioned new backfill materials need to increase the material cost by 190-340 yuan / cubic meter

[0012] Backfill methods such as geogrids and geocells have relatively high project costs and complicated construction techniques

For example, the suspending connection between the geogrid (chamber) and the platform back, in many cases it is difficult for the construction unit to operate completely according to the design

[0013] Using EPS lightweight concrete (expanded polystyrene foam (expanded polystyrene foam, referred to as EPS) to backfill bridges and culverts, the project cost is relatively high, special equipment and professional construction teams are required, and white pollution and chemical pollution sources caused by EPS lightweight concrete appear
