Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an improved artificial ice-covered climate laboratory ground construction method in order to completely solve the problem that the insulation layer is prone to water ingress and moisture in view of the defects of the current traditional artificial ice-covered climate laboratory ground construction method. method, using this method, it is possible to build a ground with good thermal insulation performance, the insulation layer is not easy to get water and damp, and has excellent load-bearing capacity. This kind of ground can meet the requirements of the ground used in artificial ice-covered climate laboratories

Abstract

The invention discloses a ground construction method for an artificial icing climate laboratory. The ground construction method comprises the steps of (A) punning the ground of the to-be-constructed artificial icing climate laboratory, binding two-way steel bars, and pouring concrete grout, so as to form a first reinforced concrete layer (8); (B) paving a first waterproof roll layer (7); (C) smearing a cement mortar protection layer (6); (D) paving a high-density polyurethane insulation board layer (5); (E) paving a second waterproof roll layer (4); (F) forming a second reinforced concrete layer (3); (G) brushing an epoxy resin wear-resisting floor paint layer (2); (H) paving a pattern galvanized steel sheet layer (1). The ground construction method has the advantages that (1) the bearing capacity is excellent; (2) an insulation layer is effectively prevented from being damped; (3) a fire risk is reduced; (4) the cost is low, and the maintenance cost is substantially lowered.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering and relates to a ground construction method for an artificial ice-covered climate laboratory. Background technique [0002] In recent years, in order to study the icing problem of UHV power transmission and transformation equipment in China, an UHV artificial icing climate laboratory has been built. The operating environment of this laboratory is harsh and the requirements for the ground are high: 1) Artificial icing climate Artificial icing tests and pollution tests are often carried out in the laboratory. During the artificial icing test, the temperature can reach minus 20 degrees, and the humidity can reach 100%. The temperature is high, the temperature can reach as high as 60 degrees above zero, the humidity can reach 100%, and the penetrating ability of steam mist is very strong, so the waterproof requirements for the ground are very high; 3) There are often vehicles coming and...
