Boiler house explosion venting port structure and construction process thereof

Abstract

The invention discloses a boiler house explosion venting port structure and a construction process thereof. The boiler house explosion venting port structure comprises a concrete structure (100), a load bearing layer (200) with the edge supported on the concrete structure (100), a waterproof layer arranged on the load bearing layer (200), a waterproof protecting layer (500) laid on the waterproof layer, covering soil (600) arranged on the waterproof protecting layer (500) and a lawn laid on the covering soil (600), wherein the load bearing layer (200) is formed by erecting profile steel and a light layer in a combined mode, and the concrete structure (100) is provided with a drainage ditch (800). A flat iron material in the prior art is replaced with the light layer, so that the load bearing layer (200) is made to be lighter and high in bearing strength; and the explosion venting port is high in safety and convenient to construct on site. The drainage ditch (800) is arranged on the periphery of the explosion venting port structure to drain peripheral accumulated water in time, so that the water resistance of the periphery of the explosion venting port structure is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a boiler room blast vent structure and a construction process thereof. Background technique [0002] According to the requirements of the relevant codes, the boiler room of the building should have a certain explosion venting area. According to the current relatively good design concept, the explosion vent of the boiler room is set on the roof of the basement, which not only meets the on-site use function, but also does not affect the aesthetics of the building. [0003] The traditional explosion venting structure uses section steel combined with flat iron to make a grid shape, and a waterproof membrane and a waterproof membrane protective layer are laid on the flat iron. After the construction of the waterproof protective layer is completed, it is covered with soil and lawn. However, this construction scheme has the problem of complicated on-site construction. In addition,...

AI Technical Summary

Problems solved by technology

However, this construction scheme has the problem of complicated on-site construction.

In addition, the combination of section steel and flat iron construction, the overall substantial activity is strong, the bond between the sticky waterproof membrane and the section steel in the later construction will fall off, and there will be cracks at the overlapping joints of the waterproof membrane.

In addition, even if the soil and lawn are covered on it, after the heavy rain, the accumulated water in the soil around the explosion vent is not well evacuated, and the accumulated water seeps into the explosion vent along the cracks around the waterproof membrane

Due to the presence of large machinery in the boiler room below, leakage will cause damage to the machinery below, resulting in huge losses
