FULL SLEEVE WELL

The invention relates to a sewer made of all-thermoplastic.

Similar wells are currently being made as follows: the polyethylene pipe is cut and the bottom of an 8 mm polyethylene sheet is welded to one end. Holes are cut in the pipe for the sleeve and discharge ends. Feed-through pipes (flow gutters) are made by splitting pipes to be threaded through the sleeve and outlet holes, after which these pipes are welded to the body pipe. The gutters are then filled with concrete. Due to the use of concrete, the maximum height of the bottom section can be 0.8 meters and due to drying, the well is ready for delivery installation after about one day. At a later stage, a riser of the desired height is welded to the bottom of the well.

When pouring concrete, vibration must be used to get the concrete in place, which is an inconvenient working method for workers.

The main disadvantages of current sewer technology compared to our invention are the following: inconvenience and time required for working methods (one day for current technology, 7 minutes for new technology), structural constraints on concrete use, such as maximum bottom height, etc. 2,761 59 causes clogging of the well, - the concrete structure is weaker compared to our invention and does not withstand the ground pressure as well.

Our invention provides decisive improvements to the above drawbacks.

In addition, the advantages of our invention are: • the well bottom is much more suitable for your invention due to its smoothness and design, - our invention can be built exactly according to the customer's wishes already at the factory, - the construction is absolutely compact.

In addition to this, the sewer according to the new method can be connected (also on site) to the same flow level as the outgoing water flow.

Transport damage when moving sewers is also reduced with our method.

Thus, with the help of our invention, a better sewer is achieved with a much easier and faster method.

In addition, the special features of the all-plastic well include that the center of the flow chute allows the best possible flow technical functionality of all different inlet and outlet angles and that the flow surfaces are slippery and seamless due to the properties of said thermoplastics.

In the following, the invention is explained in detail, also with the accompanying drawings of a well according to the method of our invention and a list of figures with explanations on page 4.

The base piece (1) of the all-plastic well is a thermoplastic disc molded to a thickness of about 10 cm, which is turned to provide a basic slope of the well bottom (2) and to form the center of the well flow channels (3). The center of the flow chutes (3) enables the best possible flow technology functionality of all different inlet and outlet angles (the angle of the flow chute is always round due to the method).

The base body is then welded by the butt welding method to a manhole height (4) of the desired length, thus avoiding additional welding seams.

Since the bottom of the well is entirely of solid polyethylene (polyethylene, polyvinyl chloride, polybutylene, polypropylene or other thermoplastic molded disc), the inlet and outlet connections to the well (7 and 8) can be made at the desired degree angle and height with a specially designed machine (6).

The flow surfaces are slippery due to the properties of the thermoplastic. The method produces deep and clear flow chutes at the bottom of the well.

In order to achieve the above effect, the invention is mainly characterized by the features set forth in claim 1.
