Upgrading Structure and Construction Method of the Road on the Crest of the Embankment in Active Service

Abstract

The invention discloses an active embankment top road upgrading structure and a construction method. The construction method is characterized by comprising the steps that rebars are embedded to the top of an original wave wall, and the embedded rebars are connected to form an integral formed rebar frame; a wave wall formwork of a heightened segment adopts hinged fracture surface formworks, and fixation of the formwork is achieved through shelves, symmetrical clamping plate, butt clamping threaded rods, upper symmetrical lug plates and formwork inner side supports; longitudinal joints, transverse contraction joints, transverse expansion joints and transverse construction joints are arranged on an exposed concrete pavement; the exposed concrete pavement adopts a whole face transverse formwork; a vibration strike-off beam is adopted for vibration of concrete, the vibration strike-off beam is connected with an n-shaped support through a strike-off beam hanging bracket, and the n-shaped support can walk along a support track; chutes are used for pouring the concrete; and a drainage ditch formwork adopts a separable inner formwork and hoisting formwork easily dismounting system. The construction efficiency is improved, and the construction process is simple and easy to practice. Relatively good technical and economic benefits can be achieved when the active embankment top road upgrading structure and the construction method are applied to the actual engineering.

Description

technical field [0001] The invention relates to an upgrade structure and construction method for roads on the top of dikes and dams in active service, which belongs to the field of water conservancy engineering and is suitable for the construction of roads on the top of dikes and dams, especially for road reconstruction and construction of existing dikes and dams. Background technique [0002] With the massive construction of high earth-rockfill dams in our country, the crest cracks and crest road reuse during the construction and operation of earth-rockfill dams have become an important research topic in recent years. In the actual application process, the conventional concrete pavement has poor integrity and is prone to cracks, which is not conducive to waterproofing. It is difficult to disassemble the formwork of the drainage ditch and the construction efficiency is low. However, the upgrade structure and construction method of the road on the crest of the embankment in ac...

Problems solved by technology

In the actual application process, the conventional concrete pavement pouring has poor integrity, is prone to cracks, is not conducive to waterproofing, and the drainage ditch formwork is difficult to disassemble, and the construction efficiency is low. However, the upgrade structure and construction method of the road on the crest of the dike and dam in active service is a more effective way to solve this problem. effective measures
