Construction method of grouted stone block revetment structure for sloping dike in river and sea reclamation area

Abstract

The invention discloses a construction method of a grouted stone block revetment structure for a sloping dike in a river and sea reclamation area. The construction method comprises the following stepsof a clearing the base layer of the sloping dike, b installing material stopping supports, c piling up the first layer of stone blocks, d piling up the second layer of stone blocks, e piling up the third layer of stone blocks, f conducting overall wetting, g continuously pouring concrete, h dismantling devices and i detecting the quality. According to the construction method, the stone blocks arepiled up layer by layer, after each layer of stone blocks are piled up, a protective measure is taken, it is guaranteed that the surface of each layer of stone blocks is flat, the piling-up gap of each layer of stone blocks is controlled so that the gaps between the layered stone blocks can be gradually reduced from top to bottom, the stone blocks which are piled up layer by layer mutually generate action force, the poured concrete can fully permeate into the gaps between the stone blocks and is solidified, shrinkage cracks are avoided, and it is guaranteed that the concrete can reach the corresponding strength and durability; besides, by the adoption of the construction method, the construction period is shortened, the height of each layer of piled-up stone blocks can be conveniently controlled, and the force borne by each layer of stone blocks is strictly controlled.

Description

technical field [0001] The invention belongs to the technical field of reclamation engineering for river and sea reclamation areas, and in particular relates to a construction method for a poured block stone surface protection structure for a slope embankment in a river and sea reclamation area. Background technique [0002] In order to prevent the interference of floods in river courses and sea areas, dykes are generally used to enclose the beach for reclamation. Reclamation of rivers and seas can renovate the flow channels on a large scale, eliminate the disasters of people along the river being displaced due to river collapses and embankment bursts, and their families are destroyed. [0003] The reclamation of rivers and seas has been applied to traditional services such as agriculture and salt industry, and the goal has been expanded to develop various target services such as industrial and mining enterprises, port construction, railway construction, and aquaculture.

Problems solved by technology

This construction method is mainly used for pouring block stones in a large area. When constructing slope embankments in river and sea reclamation areas, it is necessary to install a protective surface structure at the bottom of the side. The construction method of the surface structure is used for construction, and the use of excessive materials is small, and each layer of block stones needs to be maintained after concrete paving and irrigation, which prolongs the construction period and increases labor and construction costs.
