Industry development prospects and future prospects of glass tank, with the continuous development of economy and technology, people on the surrounding environment is also more and more strong, in the face of this situation, the traditional brick structured tank can not meet the requirements of the people, to the home environment, therefore, the glass produced septic tank is the inevitable result.
The glass is glass steel septic tank characteristics as material, has light weight and high strength, no corrosion, no leakage, good water treatment device, construction is convenient, it only needs a simple digging buried can, to a certain extent make up for the shortcomings of traditional septic tank. Has been favored by the vast number of consumers, has also been affirmed and appreciated the construction sector.
In addition, the uniform compression FRP septic tank, the compressive strength is relatively high, the product design is reasonable, but also completely solve the brick septic groundwater pollution problems, ensure the FRP septic tank steady and reliable operation. Moreover, the utility model has the advantages of convenient installation, convenient construction, low cost, small occupation area and long service life. Therefore, the widespread application on the market is no doubt.
Installation instructions for glass reinforced septic tanks:
1, the inlet and outlet pipe diameter, opening direction, water inlet and outlet pipe gap is determined by the designer or purchasing personnel, in order to the manufacturer to provide, the septic tank factory before and after the pipe body and the pool body sealing treatment.
2, if you need to change the corresponding size of the septic tank, you can negotiate with the manufacturers.
3, installation, please refer to the installation program provided by the supplier, construction or in accordance with the glass reinforced septic tank installation and construction Atlas construction.
Two, glass reinforced septic tanks technical requirements:
1, foundation trench excavation, should grasp the geological conditions, such as groundwater, and the underground water level is higher, but the use of dewatering or digging catchpit straight row.
2, the characteristic value of subgrade bearing capacity FAK is larger than 100KPa, does not meet the conditions of the foundation for the value of FAK is larger than 100KPa, the bearing capacity of the foundation after treatment. No ground water or ground water is available. See section second, section 2-1, for details.
3, backfill: septic tanks should be surrounded by 700mm backfill work surface. When the septic tank is installed, it should be filled back in time. No construction waste shall be used in the backfill and the pointed stone must be removed. The bottom, top and both sides of the septic tank are compacted with 37 lime soil, and the compacting factor is more than 95%. If there is groundwater backfill and water injection to the pipe body, avoid tank drift.
4, the soil depth of septic tanks should be greater than the local frozen soil depth, generally not more than 2.5 meters.
5, tank inspection, examination method, please refer to the glass reinforced septic tank atlas. Please refer to the atlas of glass reinforced plastic septic tanks for other matters not covered.
Three, glass reinforced septic tanks installation and Application
What about the installation of glass reinforced septic tanks, glass reinforced septic tanks and the scope of application? Many people may not know much about where to install, how to install properly, and so on. We analyze from the following points:
1., the selection of glass septic tanks, according to different buildings, individual engineering designers to calculate design parameters.
2. glass steel septic tanks to the location of the principle does not affect the building foundation; drinking water generally distance not less than 10m. from the underground water shall not be less than 30m. when the plane above the building foundation septic tank foundation plane structures, septic tank wall distance should not be less than 2M. when the plane below the building foundation septic tank foundation plane, septic tank the outer wall of the exterior wall of the building spacing distance not less than 5m.
3., the whole glass reinforced septic tank is also the smallest cover soil, 0.3m. maximum covering soil should not exceed 3m. In the cold zone, the Overburden Depth of minimum temperature lower than -10 DEG C when the septic tank shall not be less than l2m. at the lowest temperature lower than -13 DEG C, design personnel in setting depth of glass reinforced plastic septic tank, glass septic tank sleep should be set in the area under appropriate freezing line.
4. glass reinforced plastic septic tanks installed in the green belt, lawn, sidewalk, covering the soil should not exceed l.5m; can also be installed in the road lot.
5., manhole cover: but in the car, the use of double locking light double well cover and cover seat; can go through the car, the use of heavy duty double deck lock. Also according to the needs of FRP septic tank area greening needs or road paved square, cast iron or polymer ground covers in a flat, paving the ground, the manhole cover can be appropriately reduced to paving brick, the brick paved when the manhole cover must be in need of open manhole cover can be opened.
6. glass reinforced septic tank capacity, such as more than 50 m3; two cans can be connected in parallel or series settings, if connected in series, designers and users must notify the manufacturer in advance notice, the outer walls of the tank spacing shall not be less than 500mm.
At the same time, glass steel septic tank positiveeffects on groundwater protection, school, living area, shopping malls where are not the toilet, because the glass we use in the septic tank when the general method of deep buried, so basically can not see, but they play a bigger role and. The installation and transportation of glass fiber reinforced plastics are very important. The glass reinforced septic tanks also play an active role in the protection of ground water. It has become one of the basic measures of environmental protection.
