Description

Composite insulation board and concrete dam insulation system based on same
Technical Field
The invention relates to the technical field of heat preservation, in particular to a composite heat preservation plate and a concrete dam heat preservation system based on the composite heat preservation plate.
Background
In cold areas in the north of China, particularly in northeast and northwest areas, a plurality of concrete dams are built, and a plurality of concrete dams, such as a Qiaobate hydro junction, a full dam and the like, are built continuously. In the areas, the air temperature is low in winter, the wind and sand are large, the long-term temperature of the dam is an important measure for ensuring the engineering quality, and the problems of the generation of cracks of dam concrete, freeze-thaw damage of the dam concrete after water storage and the like can be prevented. At present, a foaming material heat-insulating layer with the thickness of 5cm-10cm is formed on the surface of a dam by a pasting or spraying mode in a common heat-insulating method, but a large number of engineering practices show that the falling-off phenomenon of the heat-insulating material is very common on the water surface and below, particularly in a water level change area, great difficulty is brought to the permanent heat insulation of the dam, and the method is a long-standing problem in engineering.
A large number of calculation and actual measurement results prove that the heat insulation effect can meet engineering requirements no matter whether a polystyrene board is adhered or polyurethane is sprayed, the key is to solve the problem of falling of the heat insulation layer, but the existing material system and the process method are very difficult to avoid falling, and particularly the ice-picking problem exists in a water level change area.
At present, two heat preservation schemes are mainly adopted in engineering: one is spraying polyurethane, and the other is sticking heat-insulating board. There are two kinds of construction methods to paste the heated board again: 1. after concrete pouring is finished and demoulding is carried out, the insulation board is pasted, the basic process is that polymer mortar is coated on the insulation board, the insulation board is pasted on dam surface concrete and anchored, and then the surface of the insulation board is coated with the polymer mortar again for protection; 2. and fixing the heat-insulating board on the inner side of the template during pouring, and performing polymer mortar protection on the outer surface of the heat-insulating board after pouring and removing the template.
These two insulation schemes each have advantages and disadvantages: the sprayed polyurethane has no seam and good integrity, but is difficult to follow up for heat preservation; the polystyrene board is convenient to follow up and preserve heat, but has the problem of joint and the integrity is not as good as that of sprayed polyurethane. However, both solutions have a great deal of falling-off phenomenon, especially in underwater and water level change areas, and we consider the problems and reasons as follows:
1. the reliability problem of bonding is prominent:
the concrete is a porous material, and a large amount of water can be accumulated at the bonding interface in a certain range below and above the water level, and the two schemes do not take isolation protection measures on the bonding interface, so that the long-term bonding performance is reduced.
2. The material has low surface strength, high water absorption and insufficient ice-pull resistance:
the surface strength of the two materials is lower, and the two materials have certain water absorption, the damage of floaters in the reservoir area to the surface further strengthens the freezing force with ice, and the materials are delaminated and peeled off or fall off integrally when the water level changes, namely the ice pull damage. In particular, polyurethane spraying materials are difficult to control foaming form by field spraying, the closed cell ratio is difficult to guarantee, and the water absorption is very high. The anchoring effect of the heat insulation board is very limited, and the heat insulation board is easy to break and fall off due to low overall strength and small acting range of anchoring points.
