| Claims: 1. Construction of the Outside Waterfall "LS MULTIPLE CONNECTION DROP". {FIG. 1, FIG. 3) The waterfall consists from a number of cross branches ( Fitting "A") which are connected one to each other in a straight vertical line, in the form of a complete vertical pipe. The waterfall at the top ends with the inspection opening ( 1 ) for cleaning the entire construction in the vertical direction. The inspection opening is closed with a sealed cover. The waterfall at the bottom ends with a 90-degree angle (2), which consists of two 45-degree angles and a horizontal pipe section and connects to the opening of a control cell using a standard bell-shaped seal (3). Sewage exits from the waterfall and enters to the control cell through the 90-degree angle and the horizontal pipe section. The construction of each single cross branch allows for a horizontal sewer pipe (4) that enters the waterfall, connecting to the waterfall in any horizontal angle as needed. On the other side each cross branch connects to the opening in the control cell wall using two 15-degree vertical angles (5) and a horizontal pipe section (6) with a standard seal (7), which ends in the form of a circular orifice (S) on the inside of the control cell wall and is designed to clean the cross branch. The inspection orifice [8) for cleaning the cross branch is designed with a rising pipe in the direction of the control cell wall to prevent wastewater spill through the orifice. One of the 15-degrees angles adjacent to the cross branch ( Fitting "A") is integrated into the cross branch as a monolithic structure. The height difference between the horizontal sewer pipes (4) that enters to the waterfall, can be any value but not less than 35 centimeters. The amount of sewer pipes (4) connected to the waterfall is not limited, but depends on the depth of the control cell. Waterfall construction allows the connection of sewer pipes in the needed amount, at different levels, at a horizontal angle between 0 and 90 degrees. There is access to cleaning every detail and part of the waterfall. The waterfall construction can be adapted to the sewer pipes of any diameter connected to it. 2. Construction of the Cross Branch. [FIG. 2) The cross branch ( Fitting "A") is a component of the waterfall as the monolithic uniform accessory. On the side of the sewer pipe that enters to the waterfall, inside the cross branch is built a preparation ( 9 ) for connecting the pipe with the same diameter as the pipe connecting to the cross branch. The preparation is built at an angle of 88.5 degrees between the vertical axis of the waterfall and the horizontal sewer pipe axis that connects to it. Horizontal angle of the sewer pipe at the entrance to the waterfall is fixed in each individual cross branch. Possible horizontal angle is between 0 and 90 degrees. On the side of the exit from the cross branch, inside the cross branch is built a preparation [10) for connecting in the direction of the inspection orifice of the control cell wall, which consists of a spout and a vertical angle of 15 degrees with the same diameter as the pipe connected to the waterfall. On both sides of the cross branch in the vertical direction, inside the cross branch is built a preparation [11) for connecting the upper and lower cross branches are the same diameter. To the waterfall's upper cross branch will be connected the pipe which rises to the top inspection opening for cleaning the waterfall in the vertical direction. Each whole cross branch is made of single diameter. |
Invention Description: Outside Waterfall "LS MULTIPLE CONNECTION DROP" is intended for the taking of domestic waste water from the sewage collector pipes from residential and similar buildings on different levels and different sharp angles in connection point to control sewage cell.
"LS MULTIPLE CONNECTION DROP" appropriate for the disposal of waste water from row house buildings, where several residential units are built adjacent to each other, when each housing unit is built on different floor levels or alternatively a number of housing units with entrances from a common stairwell.
Row house construction is characterized by a very limited area around the ground floor, a high density of underground infrastructure located on the area within the residential property, a large number of sewage down pipes (vertical sewage collector pipes) inside the buildings and horizontal sewage collector pipes coming out from the buildings.
Any change in level and orientation (horizontal angle) of a sewage pipe requires the installation of an inspection opening (hole for cleaning) or control sewage cell (sewage well).
The "LS MULTIPLE CONNECTION DROP" waterfall is an engineering solution for connection a number of sewage collector pipes that exit outside from the buildings to the joint point of a single sewage well, without installing additional control cells.
That lead to saving of valuable building space and significant financial saving. A control cell with a conventional pipe connection allows the pipes to be inserted at a horizontal angle not less than 35 degrees between the pipe axes.
Using "LS MULTIPLE CONNECTION DROP" waterfall with a control cell allows to connect the collector pipes at any sharp angle less than 35 degrees between the pipe axes.
The "LS MULTIPLE CONNECTION DROP" waterfall is appropriate for waste water disposal in construction of cottages, as well as for apartment buildings.
Description of Invention production methods:
The "LS MULTIPLE CONNECTION DROP" waterfall will be assembled on construction sites from standard high density polyethylene (HDPE) fittings, accessories and materials manufactured by AKATHERM.
The new accessory offered by the inventor is a "cross-branch" according to item "A" shown on the attached drawing.
The method of working for the water fall assembly - electric welding electrofusion (E.F.) or butt welding (B.W.).
Technical Problems That Invention Solve:
1. Large amount of control cells around the residential buildings.
2. Horizontal angle restriction in piping entry to control cell, where additional control cells are required. 3. Difficulty maintenance of control cells and sewage collectors around buildings because of a lack of access to them (control cell with waterfall "LS MULTIPLE CONNECTION DROP" can be installed in the confined area and open to access, such as private parking or approach to the building entrance).
4. Lack of space for laying and coordinating underground infrastructure.
5. Failure to connect several pipes at different levels and at different angle less than 35 degrees between the pipe axes, to conventional waterfall.
