Description

The one section Widening Embankment structure of suspended wall height barricade embankment near water and construction method

Technical field

The present invention relates to a kind of Widening Embankment structure, particularly to the one section Widening Embankment structure of suspended wall height barricade embankment near water and construction method. Belong to highway engineering field, it is adaptable to old road reconstruction and extension project, be particularly well-suited to suspended wall height barricade embankment widening project near water.

Background technology

In recent years, along with developing rapidly of China's economy, the volume of traffic cumulative year after year of road, underestimate owing to early stage builds the road swift and violent growth the to traffic, the road that some operation amounts are big has presented the situation that the volume of traffic is saturated so that transportation is severely impacted. For meeting the requirement of growing traffic and social development, it is inevitable that existing road widening has been become.

It is the engineering that suspended wall height barricade embankment section is widened for old road dike, normally it is open to traffic in situation, carry out the Widening Construction of embankment, owing to the stability and normal safe for ensureing old road dike is open to traffic, when widening, suspended wall reinforcement height barricade cannot once or all be removed, therefore cannot carry out the old and new's road dyke combination construction by step excavation traditionally. Owing to the stability, uniformity of new-old concrete bond, intensity are different with compaction rate in widening of subgrade engineering, new-old concrete bond can produce different sedimentations, thus can cause road surface, along seam, longitudinal crack occurs, the problem mainly solved in roadbed widening processing procedure should be handle the ground of coupling section of the new and old road position well, strengthens the bond strength of new-old concrete bond.

The Settlement Consolidation being typically due to old road roadbed is basicly stable, and the new subgrade settlement time is short, and new-old concrete bond junction will produce differential settlement, thus producing longitudinal crack. The differential settlement of new-old concrete bond causes that cement concrete slab produces disconnected plate under load action, and asphalt concrete pavement produces reflection crack, driving quality is brought very big impact, strengthens cost of transportation, even entail dangers to traffic safety.Although more existing measures that can be used for solving Widened roads area differentiation settlement issues in engineering, the combination application of various measures is for controlling embankment later stage differential deformation, strengthen the globality at new and old road embankment loading position to have positive effect, but existing measure is big for embankment height, difference settlement control requires that high section is difficult to be suitable for.

Existing one highway widening embankment structure (ZL:201310561704.1) near water, is formed by the combination reinforced structure of outside water proof maintaining pile and inner side at present. Though this structure can improve the globality widening highway subgrade under suitable engineering specifications, but the training works of former road surface structare layer is relatively big, during oblique grouting and reinforcing body construction, there is certain risk, be unsuitable for suspended wall height barricade embankment widening project near water.

In sum, although the method for more existing punishment soft soil roadbed settlement abnormal problems in subgrade engineering, each treatment measures, method achieve good consolidation effect under suitable engineering specifications, but working procedure is complex loaded down with trivial details mostly, some sections still there will be, in the later stage, the problem that sedimentation is abnormal.

Given this, for effectively controlling the relative settlement of the old and new's embankment impact on road structure after road widening, reduce the differential settlement between new-old concrete bond, need the compatible deformation inventing a kind of the old and new's of enhancing embankment and stability at present badly, prevent extraneous water body from penetrating into, improving the height barricade embankment section Widening Embankment structure of suspended wall near water and the construction method of new Widening Embankment anti-floating ability.

Summary of the invention
