FRP integral manhole, elbow, tee and other customizable accessories
The overall manhole of glass fiber reinforced plastic sand pipe is the best accessory for sewage discharge pipelines, and it is a necessary facility to facilitate inspection and dredge pipelines to prevent pipeline clogging.
The traditional brick manhole construction method is to use bricks to build the well body, then insert the pipe into the well body and fill the pipe interface with cement mortar.The process is backward, the construction efficiency is low, and the poor connection effect will lead to serious leakage and leakage, and it violates the principle of standardization and environmental protection.
In response to the policy of energy conservation, emission reduction and environmental protection, the company's glass fiber reinforced plastic pipe as a whole manhole is made of the same material as the main pipeline and assembled separately. The installation is flexible and convenient, and it is not limited by climatic conditions. It can meet the needs of large-scale projects and greatly improve construction efficiency.The wellhead adopts “Type 0" rubber ring, which realizes the same flexible connection technology as the main line, has good sealing performance, can bring great convenience to the construction, and can fully adapt to certain ground settlement requirements.
Compared with brick manholes, glass fiber reinforced plastic manholes have four advantages:：
1. The excavation area is small, the construction is convenient, and the construction efficiency is greatly improved.
2. The pipe ports are tightly connected, which can effectively prevent water seepage and leakage.
3. When the ground road forms a settlement, the expansion and contraction of the steel sleeve can be consistent with the ground settlement, so as to effectively prevent the pipeline from being damaged or broken.
4. The overall FRP manhole has good acid, alkali and dirt resistance, no fouling, faster water flow, and 5-10 times the life span of brick wells.
The FRP integral manhole and other accessories produced by the company can meet socket connections, flange connections and curve connections at various angles, and are suitable for pipelines of various specifications.It can fully meet the requirements of energy saving, land saving, environmental protection, and rapid construction.
Installation requirements description
1. When laying stone sand and yellow sand after slotting, it is generally the same as the sewer pipeline.
2. Before the main line glass fiber reinforced plastic sand-gripped pipe is connected, the inner wall of the socket working surface and the outer surface, the bottom of the socket groove and the surface of the rubber ring must be coated with lubricant. It is strictly forbidden to leak lubricant for installation to avoid water leakage caused by the fracture of the rubber ring.
3. After the interface socket is connected, the verticality of the well body must be corrected and fixed.
4. When backfilling yellow sand, starting from the bottom of both sides of the main line, it must be watered and wetted in layers and compacted in layers.Generally, the thickness of each layer shall not exceed 50cm, and it shall be within the range of ≥50cm around the well body.When backfilling yellow sand, the layered backfilling method must be followed, and it is strictly prohibited to backfill with soil or stones.
5. The elevation must be corrected at the settlement telescopic steel sleeve. The settlement telescopic sleeve generally adopts concrete or three slag to fix the elevation, but it must be completely dense.
