Embodiment Construction

[0026] Such as Figure 1 ~ Figure 4 As shown, an anti-seismic composite panel structure of an earth-rock dam is composed of an upper concrete panel 1, an asphalt layer 2 and a lower concrete panel 3. Both the upper concrete panel 1 and the lower concrete panel 3 are composed of a plurality of rectangular concrete blocks 7, the side length of the rectangular concrete blocks 7 is 12-18m, and the thickness is 0.2-0.4m. A longitudinal split 5 and a transverse split 6 are reserved between the rectangular concrete block 7 and the rectangular concrete block 7, with a width of 1-2 cm; the space between the upper concrete panel 1 and the lower concrete panel 3 is filled with an asphalt layer 2, and the thickness of the asphalt layer is 2 cm. ~5cm; both the longitudinal splits 5 and the transverse splits 6 between the rectangular concrete blocks 7 are filled with asphalt. Each rectangular concrete block 7 of the upper concrete panel 1 and the lower concrete panel 3 adopts a staggered o...

Abstract

The invention discloses an anti-seismic combination slab and a construction method thereof. The anti-seismic combination slab consists of concrete slabs of upper and lower layers and pitch layers, wherein the concrete slabs are formed by combining rectangular concrete blocks, the rectangular concrete blocks of the concrete slabs of the upper and the lower layers are arranged in a staggered mode, and longitudinal and horizontal parting seams are reversed among the rectangular concrete blocks; the pitch layers are arranged between the concrete slabs of the upper and the lower layers, and pitch is filled in the horizontal seams and the longitudinal seams among the rectangular concrete blocks. The construction method comprises the technical steps of paving cushion layers, pouring the concrete slab of the lower layer for asphalting in the parting seams, paving the pitch layers, pouring the concrete slab of the upper layer for the asphalting in the parting seams and the like. The anti-seismic combination slab has the advantages of high capability of adapting to deformation due to earthquake, simple and convenient construction, low construction cost and good effect.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to an earth-rock dam face plate and a construction method thereof, in particular to an earth-rock dam anti-seismic composite face plate and a construction method thereof. Background technique [0002] As a green and renewable energy source, hydropower has received great attention. At present, my country's hydropower development has experienced an unprecedented climax. Face rockfill dams are favored because they can make full use of local natural materials, can adapt to different geological conditions, and are relatively simple in construction methods. The hydropower projects represented by the construction of medium and high earth-rock dams in the western development have put forward higher requirements for the design of earth-rock dams. The height of earth-rock dams has developed from tens of meters to 100 meters, 200 meters, and even 300 meters. Such as Shuibu...
