Description of the invention
"Duct flap for combination shaft"

The invention of the sewer valve lies in the technical Urban civil engineering - sewerage (urban drainage)

Purpose of the invention:

The invention ensures that the dirt unc Rainwater pipe axially one above the other in a Baugru'jo can be relocated. This type of construction would mean an average of 20 - 25 / ί compared to lines to be built separately Lead to cost savings.

1) General explanation

At the '/ number and manufacture of urban drainage network Irennial sewerage is becoming more and more popular. Here, dirt and rainwater are in separate lines and also derived in separate systems. So it igo required, and so far also common, in a gev / ij ^ en. distance a rainwater and a sewage pipe to bt "u" n. The center distance is mostly depending on the pipe casting and. Soil types 2 - 3 m. The sewage pipe i: i is also usually located deeper to connect basement drainage. Regon water pipelines are almost always higher, because in these i-'ulle yes only;) ach-, liof- una street areas with sufficient gradient to drain.

I) Io. Construction of two construction pits for the rain and Scliinutz- ■,; a.'jaG.L'lGituxig is a significant cost factor in ei on Baui'joaton. In many cases, attempts have already been made to lay the Loidor lines so close to each other that a common excavation is created, which, however, is wider than a normal excavation, because the children's distance is determined by the construction bridge through the access and inspection shafts. £ 3 v / ^σ a i will always show that the manholes of both systems are “close to andor”, i-ian can pass through the minimum acha distance zv / ar noüli

agile and has the disadvantage that with aifötaiva..i.;: yes, rainwater overflows into the Schmutav, ^r asaerloi: tui '^ - · is possible. From a common excavation wire, also ■ οΛ '^ ό · α-half distance, because due to the different :! .aölaenlagen the lines a stepped construction pit cross-section is required, which makes more effort than usual for the stiffening and securing of the construction pit, especially with flowing soil types (fine sand, etc.). Almost every solution is to lay dirt and rainwater pipes with the axes on top of each other. Because now only a normal excavation is required, which is determined by the sewage pipe, which is usually deeper. This eliminates all costs for the construction of the excavation for the rainwater lines. '

2) The execution, sewage and rainwater pipe .in one Construction pit, enables a shaft construction in which both drainage systems are combined in a normal-sized shaft are (Plan Kr. 2 and 5). This shaft - called "combination shaft - Must have a horizontal ceiling that divides the viewing shaft into a lower dirty water shaft and an upper .u-Lü ^ oiiwasser- ■ shaft Splits. Since the lower part of the shaft also serves: α: άά monitored must be, a flap is to be arranged in this false ceiling, to which the following requirements are made:

1. The flap must close watertight.

2. The flap must meet the hydraulic conditions of a 1-Canai shaft bottom correspond.

3. The flap must be easy to operate.

4. The flap must have a pass-through when it is open release that a person passes with his whole body can ren.

5. The flap must be made of corrosion-resistant material. 6. The flap must carry the excess amount of water can.

The duct flap is constructed in two variations (Eyp 1 and iyp 2). ■ '. . Al '

The duct flap lies in a cast-iron round false ceiling, which is suitable for installation in round shafts without a solid false ceiling » (Plan. JTr. ,, la) *

The flap itself is made of cast iron. approx. 20 mm thick, hinged on one side. When opened, it reveals a clear opening of 50 cm 60 cm, sufficient as a through culupf for operation through * Intermediate ^{decce takes place:} by grinding edges or unrcu installation of a CTun _t aiaichturigi

It is believed that with these. Pormen all necessary ATD kinks in line routes can be recorded " The hinges of the "flap" are made of rustproof material (e.g. brass or Firostahl). To open the flap there is one Use a galvanized steel chain with a handle on the outside is to be hung on the manhole cover.

In this way, actuation of the flap is also possible from Strai-te-n ⁼ level. The flap and the outer surfaces. the frame or the surfaces of the cast-iron false ceiling are to be stranded with an anti-corrosion coating.
