Oil leakage prevention heavy load terrace structure resisting deformation of foundation

Abstract

The invention discloses an oil leakage prevention heavy load terrace structure resisting deformation of a foundation. The oil leakage prevention heavy load terrace structure resisting the deformation of the foundation comprises an oil leakage prevention terrace formed by a macadam cushion layer, a concrete cushion layer, a mortar layer and a reinforced concrete surface layer all of which are arranged in sequence on the rammed earth foundation. The oil leakage prevention heavy load terrace structure resisting the deformation of the foundation is characterized in that a diversion layer and an HDPE geomembrane layer are arranged between the concrete cushion layer and the mortar layer, oil discharging trenches are formed in the periphery of the structures, above the geomembrane layer, of the terrace, and the diversion layer is diversion net sheets of the geomembrane which has the vertical composite water seepage and inverted filtering functions. Compared with the prior art, the oil leakage prevention heavy load terrace structure resisting the deformation of the foundation has the advantages of being high in leakage resistance level, simple in structure, convenient to construct, short in cycle, capable of effectively avoiding leakage prevention blind spots, controlling leakage of oil contaminations and preventing the oil contaminations from contaminating water and soil under the foundation, and especially suitable for heavy load oil leakage prevention terraces with large difference deformation of the foundation.

Description

[0001] technical field [0002] The invention relates to the technical field of building foundations, in particular to an anti-seepage oil heavy-duty floor structure resistant to foundation deformation. Background technique [0003] At present, the floor of the dismantling site of the ship breaking yard or the floor of the site with high requirements for oil leakage prevention generally adopts the oil-proof construction method of combining a rigid anti-seepage surface layer and a rigid oil-proof isolation layer. In this construction method, a rigid oil-proof concrete surface layer is set on the surface of the floor. According to the amount and type of oil pollution, two structures under the surface layer are constructed with an oil-proof isolation layer and without an oil-proof layer. It does not have an oil-proof isolation layer construction, and only relies on a layer of oil-proof fine stone concrete surface to prevent oil leakage, so it is only suitable for general oil-pr...

AI Technical Summary

Problems solved by technology

Due to the influence of differential settlement of the foundation, the surface layer of oil-proof concrete floor will inevitably crack, while the oil-proof isolation layer of polyurethane or polymer mortar coating has poor plastic deformation ability on the whole, and it is difficult to adapt to large differential deformation of the foundation

[0004] Existing anti-oil leakage floor technology, for 3t / m 2 The oil-proof floor under the above heavy load, when the soil quality of the foundation soil under the floor is poor and the foundation settlement is large, it is difficult to meet the requirements of the environmental protection department for oil leakage prevention

Especially when the polyurethane coating is used as the oil-proof isolation layer, the quality of its painting is not easy to control. During construction, it is common to have leakage points due to poor bonding between the coating and the cushion or uneven and incomplete local painting. Each brushing requires a certain interval, and the construction period is relatively long
