Description

Novel concrete pool wall anticorrosion structure of effluent water sump

Technical Field

The utility model relates to a building anticorrosion technical field especially relates to a novel effluent water sump concrete pool wall anticorrosion structure.

Background

At present, the treatment of urban domestic sewage and industrial sewage is the central importance of national water environment protection work, and the construction of facilities for treating domestic sewage and industrial sewage is required to be considered as the important content of infrastructure, and a sewage tank bears the function of storing sewage, thereby being the most important part in the sewage treatment link. Therefore, the design of the septic tank is crucial to the overall sewage treatment system.

However, almost all concrete elements have cracks, and the cracks allowed to occur in the concrete elements for different purposes are clearly defined in the specifications, and in fact the concrete elements are operated with cracks. But the width of the crack is controlled within an allowable range, otherwise, the structure is brought with a safety hazard, and the structure is seriously damaged. The sewage pool contains a large amount of corrosive media, which can cause corrosion to the concrete structure and corrosion to the reinforcing steel bars by permeation, even cause leakage, thereby affecting the normal working condition of the concrete structure. Therefore, a proper protective material needs to be selected to ensure the anticorrosion effect in the using process, and meanwhile, the construction efficiency needs to be considered. The traditional anticorrosion construction needs to brush two layers of base materials and putty scraping, and multiple layers of glass fiber reinforced plastic layers are pasted alternately, so that more than ten working procedures are needed, certain drying time is needed between each working procedure, certain requirements on temperature and weather are met in the construction process, the construction period is long, and the problems of unstable connection quality, water leakage between layers and the like easily occur due to too many waterproof layers.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel effluent water sump concrete pond wall anticorrosion structure, it is effectual anticorrosive and prevent crossing water, it is convenient to be under construction.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a novel effluent water sump concrete pool wall anticorrosion structure which characterized in that: the concrete sewage pool rapid-hardening rubber asphalt layer comprises a rapid-hardening rubber asphalt layer on the inner wall of a concrete sewage pool, wherein a glass fiber cloth layer is arranged on the side portion of the rapid-hardening rubber asphalt layer, and an anti-corrosion paint surface layer is arranged on the side portion of the glass fiber cloth layer.

Preferably, an HDPE layer is arranged between the quick-setting rubber asphalt layer and the inner wall of the sewage pool.

Preferably, a putty layer is arranged between the glass fiber cloth layer and the anti-corrosion paint surface layer.

Preferably, the thickness of the quick-setting rubber asphalt layer is 1-3 mm.

Preferably, the anticorrosive paint surface layer is a chlorosulfonated polyethylene anticorrosive paint layer.

Preferably, the thickness of the anti-corrosion paint surface layer is 0.2-0.6 mm.

To sum up, compare with prior art, the utility model has the advantages of: the HDPE layer is arranged to simplify the tank wall processing work before the rapid hardening rubber asphalt layer is sprayed, the HDPE layer is matched with the rapid hardening rubber asphalt layer to improve the water mixing prevention performance and the smoothness of an anti-corrosion structure, and the construction period is greatly shortened.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The reference numbers in the figures are as follows:

1. the coating comprises a quick-setting rubber asphalt layer, a HDPE layer, a glass fiber cloth layer, a putty layer and an anticorrosive paint surface layer, wherein the HDPE layer is 2, the glass fiber cloth layer is 3, the putty layer is 4, and the anticorrosive paint surface layer is 5.

Detailed Description

The invention will be further described with reference to the following examples in the drawings.

As shown in figure 1, the anti-corrosion structure for the concrete pool wall of the sewage pool comprises a quick-setting rubber asphalt layer 1 on the inner wall of the concrete sewage pool, a glass fiber cloth layer 3 is arranged on the side portion of the quick-setting rubber asphalt layer 1, and an anti-corrosion paint surface layer 5 is arranged on the side portion of the glass fiber cloth layer 3. The quick-setting rubber asphalt layer 1 is convenient and quick to coat, has the characteristics of high extensibility and high durability, and can form an even and compact skin type waterproof coating film through continuous spraying operation, so that the concrete pool wall is comprehensively and effectively protected, and the service life of a sewage pool is prolonged. The glass fiber cloth layer 3 increases the strength of the anti-corrosion structure, and when the anti-corrosion structure is laid, the glass fiber cloth is in staggered lap joint, and the lap joint width needs to be larger than 50 mm.

An HDPE layer 2 can be arranged between the quick-setting rubber asphalt layer 1 and the inner wall of the sewage pool. HDPE layer 2 accessible welding forms the overall structure of cover at the effluent water sump inboard, and its accessible is spread anti-technique of gluing in advance and is linked with the interior wall glue of effluent water sump and form integrative smooth waterproof layer. The HDPE layer 2 reduces the treatment process of the surface of the wall of the sewage pool, and the quick-setting rubber asphalt layer 1 can be coated immediately. The thickness of the quick-setting rubber asphalt layer 1 is 3mm, and criss-cross continuous spraying is carried out by adopting the principle of from far to near and from low to high so as to ensure uniform thickness. The quick-setting rubber asphalt layer 1 has the characteristics of high extensibility, high durability and the like, and a continuous compact waterproof coating film is formed and matched with the HDPE layer 2, so that water leakage between a coated anti-corrosion waterproof layer and a structural layer is avoided.

A putty layer 4 is arranged between the glass fiber cloth layer 3 and the anti-corrosion paint surface layer 5. After the lining of the glass cloth is finished, the glass cloth is cured for 24 hours, and the defects are repaired and the putty layer 4 is applied to improve the compactness. The putty layer 4 is 0.3mm thick.

The anti-corrosion paint surface layer 5 is a chlorosulfonated polyethylene anti-corrosion paint layer which is hard and strong in adhesive capacity. The thickness of the anti-corrosion paint surface layer 5 is 0.3mm, and the anti-corrosion paint surface layer can be arranged on the putty layer 4 through brushing or rolling. The anticorrosion paint surface layer 5 can be provided with one or two layers.

The above description is only for explaining the present invention, so that the person skilled in the art can completely implement the present invention, but not for limiting the present invention, and after reading the present specification, the person skilled in the art can make modifications to the present embodiment as required without inventive contribution, which are all modifications without inventive contribution, but are protected by patent laws within the scope of the claims of the present invention.
