Equipment Introduction

A septic tank is a device that processes feces and filters and settles them. The principle is that the solidified material decomposes at the bottom of the pool, and the hydrated material in the upper layer flows away into the pipeline, preventing pipeline blockage and giving sufficient time for the solidified material (feces, garbage, etc.) to hydrolyze. Septic tank refers to a small-scale treatment structure that separates and settles domestic sewage and anaerobically digests sludge. Fiberglass reinforced plastic, also known as fiberglass reinforced plastic, is made by combining fiberglass and its products into bones (reinforcement materials) and resin into muscles (matrix materials). It has the hardness, high temperature resistance, corrosion resistance, and long service life of glass, as well as the characteristics of being hard, unbreakable, and compressive like steel; Its density is only 1/5 of carbon steel, and its tensile strength is close to or even exceeds that of carbon steel. Its specific strength can be compared to alloy steel, and its tensile strength reaches over 500 kg/cm2.

Equipment features

1. The fiberglass reinforced plastic septic tank is made of high-strength fiberglass composite material, which has the characteristics of compressive strength, corrosion resistance, impact resistance, tensile strength, etc. Its service life can be synchronized with the building.

2. Glass reinforced plastic septic tank, integrated into one piece, shortens the construction period in the later stage of the building. It can be installed and used on the same day, improving efficiency and enhancing the economic and social benefits of the industry.

3. Glass reinforced plastic septic tanks have good overall production tightness and no leakage, solving the problem of underground water pollution caused by brick masonry, providing environmental protection, improving the operation of septic tanks, and ensuring the anaerobic decay function of septic tanks. Compared with brick and concrete septic tanks, their cleaning time is shorter, which brings great convenience to property management.

4. Glass reinforced plastic septic tanks have a small footprint and good environmental benefits, making them particularly suitable for the renovation of sewage systems in old city construction areas. They have the advantage of flexible site selection and can save land in the increasing underground pipeline network in residential projects, improving the comprehensive facilities of the pipeline network.

5. The economic indicators of glass reinforced concrete septic tanks are lower than the final settlement prices of brick and reinforced concrete septic tanks. Affordable and affordable, accepted by many users, and supported by numerous real estate companies and construction units.

6. The glass septic tank adopts a cylindrical shell, and the inner wall is designed with a reinforced hard shell curved structure, with high compressive strength. After testing by relevant departments, all performance indicators meet the design requirements.

Application scope:

Used for sewage collection and treatment in residential areas, office buildings, hotels and restaurants, schools, hospitals, barracks, public toilets, industrial parks, rural transformation and other places.

Analysis and comparison of several installation processes for fiberglass septic tanks:

1. Installation of a single integrated septic tank: convenient construction, uniform settlement, good treatment effect, and even stress distribution. This plan is reasonable.

2. Parallel installation of two products: Worried about uneven soil settlement or the possibility of inconsistent water inlet for the two septic tanks during manual installation, resulting in uneven distribution of flow between the two septic tanks, one overloaded and the other possibly decorative.

3. Two septic tanks are installed in series: one septic tank is prone to blockage and has a high construction cost. The product is designed with four levels of septic tanks and staggered upper and lower compartment boards. The deep burial depth of fiberglass septic tanks is generally within 2500mm, which is their safety theoretical value. However, in practice, the current depth can reach 4000mm without any problem.

Construction precautions for fiberglass septic tanks:

1. When excavating the foundation trench, the geological conditions should be understood.

2. The location and burial depth of the fiberglass septic tank should be strictly set out and positioned according to the design requirements.

3. After the tempered glass septic tank is in place, it should be filled with soil in a timely manner, and the tank should be filled with water to prevent displacement. Backfill soil should be sieved, free of sharp stones and construction waste, and compacted with a soil density of 0.95 when there is no groundwater. Pay special attention to filling the area around the bottom of the tank with plain soil or yellow sand: when there is groundwater, fill the bottom of the tank with plain soil or yellow sand, and ensure that the fixed position of the tank is evenly stressed.

4. During rainy season construction, drainage facilities should be provided to prevent water accumulation in the foundation pit and slope collapse. At the same time, the tank should be filled with water to prevent floating and displacement.

5. Construction should be carried out in accordance with the relevant engineering construction and acceptance specifications.
