Precast fence plate dam reinforcing method

Abstract

The invention relates to a precast fence plate dam reinforcing method. The method comprises the following steps of: firstly precasting a fence plate, and conserving the precast fence plate until 75% of the design strength standard value is achieved; paving a layer stone blocks on a dam surface to be constructed, manuacturing a screed strip underlayer on the stone blocks, conveying the precast fence plate to a to-be-reinforced dam, manually regulating the position so that the fence plate is placed on the screed strip underlayer, and performing edge beam form erecting after placement is finished; then binding edge beam steel bars, pouring concretes, vibrating, trowelling, conserving until the dam is qualified, and then dismounting a template, thus finishing dam reinforcing construction. The fence plate dam reinforcing construction method is high in efficiency, low in cost, easy for formation of multiple parallel working surfaces and less in influence of tide water on construction; and furthermore, fence plates are connected by virtue of the steel bars and are poured by the concretes, a molded dam reinforcing structure has two advantages of reliable protective property and good wave eliminating effect, and is less in wave overtopping amount and long in service life.

Description

technical field [0001] The invention relates to a construction method for embankment, in particular to a method for embankment protection by using fence boards. technical background [0002] In recent years, the enthusiasm for developing and utilizing the ocean in China's coastal areas has been unprecedentedly high. Under the circumstances that major national projects such as nuclear power, steel, and heavy chemicals have gathered in the coastal areas, land reclamation has the advantages of less constraints, low cost, and greater freedom of land use. Therefore, reclamation of land from the sea has realistic requirements and motivation, which is also in line with the background of the general policy of stimulating domestic demand through increased investment. The traditional filling stone and nut block embankment construction requires the use of large-scale equipment such as floating cranes on the water surface. The construction cost is high, the safety is poor, and it cannot...

Problems solved by technology

The traditional filling stone and nut block embankment construction requires the use of large-scale equipment such as floating cranes on the water surface. The construction cost is high, the safety is poor, and it cannot play the role of wave dissipation, and the life of the embankment is short.

The current construction of the embankment also involves stacking sand bags directly on the embankment surface, pouring concrete into the sand bags, and filling the gaps between the sand bags with concrete. This kind of construction is greatly affected by the tide, and the setting time of the concrete cannot meet the standard. Each sand bag is independent of each other, prone to quality problems such as berm breakage
