Description

Application area

The inventive utility model relates to devices for collecting and draining water from ground pavements, namely, slotted drainage trays. It can be used for areas with low and high traffic pedestrians and vehicles.

State of the art

Widespread European standard EN 1433 "Channel gutters for roads and pedestrian zones. Classification, design, testing, labeling and conformity assessment. ” A variant of this standard is introduced in the Republic of Belarus STB EN 1433-2009 “Drainage trays for the removal of effluents from the surface of transport and pedestrian zones. Classification, manufacturing requirements, test methods, conformity assessment and labeling. ” These standards define the slotted tray and sketch showing the general design principle. Slotted tray is a prefabricated device consisting of a gutter with a closed profile and a constant or intermittent slotted hole at the top, which serves to receive surface water.

The world practice of manufacturing slotted trays has received the following main directions of development:

- slotted concrete trays made of concrete or polymer concrete as a single part (patent RU 102360 U1),

- slotted trays of prefabricated construction made entirely of metal (patent RU 107194 U1, RU 2314387 C2),

- slotted trays of prefabricated construction, performed on the principle that the base of the tray of concrete, polymer concrete or plastic is covered with a metal coating forming a gap for receiving water (EP 2677089 A1, DE 20318130 U1).

All the above types of slotted trays do not fully solve the problem of organizing a slope along the bottom of the tray. The above types of slotted trays have a rigid reference to the level of the slit to the bottom of the tray; any in-place adjustments are not possible. Also, the practice of using slotted trays determines their area of application in the surface layer of pavement. To organize the deepening of these types of trays more than 1 meter, these designs are not applicable since their mass will increase depending on the increase in the depth of laying, and accordingly the cost will also increase significantly.

The objective of the utility model to be solved is to create a design of a drainage slotted tray allowing to expand the technical possibilities of using slotted trays by significantly increasing the depth of the lower part of the tray and adding the possibility of convenient organization of slopes at the level of the upper slot and at the bottom of the tray when installed in place.

The technical result consists in expanding the technical capabilities of using slotted trays by adjusting the height of the position of the water intake slit relative to the bottom of the tray in a wide range, as well as significantly increasing the depth of the lower part of the tray.

Utility Model Essence

The technical result is achieved by the fact that the proposed module of the slotted drainage tray consists of a slotted intake grill connected to the intake housing, which has at least one hole, a closed tray, which has at least one hole in the upper part, and at least one pipe pipe connecting the hole in the water intake housing and the hole in the tray. The closed tray is formed by the upper and lower shells, connected in any way, ensuring tightness and strength. The upper and lower shells of the tray are equipped with stiffeners and protruding parts with seals that allow the trays to be sealed in a line. The connection of the pipe nozzle with the hole in the water intake housing and the hole in the tray is tight and is preferably carried out through rubber seals. The shape of the pipe fitting matches the shape of the hole.

The design of the slotted drainage tray consists of the lower module of the drainage tray, the upper module of the drainage slotted grate, interconnected by at least one pipe nozzle. The connection of the upper and lower modules is such that the distance between the upper and lower modules can be adjusted locally, thereby maintaining design marks for the water intake grill and the bottom of the tray independently. The lower module consists of two shells with a rib cage, forming an assembled closed profile of the drainage tray. The upper shell has at least one hole for attaching a pipe nozzle through which water enters the tray. The shells can be connected in any way that provides tightness and strength, for example, welding, mechanical assembly using fasteners, gluing, soldering. The upper module consists of a slotted water intake grill connected to the water intake housing, which has at least one outlet under the pipe for subsequent connection with the lower module of the tray through the pipe nozzle. Ensuring the tightness of the connection of the upper and lower modules through the pipe nozzles is provided, for example, by rubber seals, adhesive sealants, soldering. The pipe profile may have a different geometry. During installation, the resulting modules of the slotted trays are assembled in a line, and the design of the lower tray module allows the modules to be sealed in length through the use of seals, for example rubber, and the presence of the protruding part of the tray. Additional fastening of the lower modules to each other can be done in various ways: bolt fastening, soldering, welding, screw fastening, gluing, jointing on sealants.

Utility Model Implementation

The inventive slotted drainage tray consists of the following main parts (Fig. 1, Fig. 2):

1 - slotted water intake grill,

2 - water intake housing

3 - pipe pipe,

4 - upper shell

5 - lower shell

6 - upper seal,

7 - lower seal

8 - rib of the upper shell,

9 - rib of the lower shell,

10 - longitudinal seal,

11 - soil or concrete.

The slotted drainage tray (Fig. 1) contains a slotted drainage grid 1 made of durable material that provides the design load class. The lattice is attached to the intake housing 2, which performs the function of directing water into the pipe nozzle 3, and then the water enters the closed-profile tray formed by the upper shell 4 and the lower shell 5. The tightness of the docking of the water intake housing, pipe nozzle and upper shell is provided by the upper seal 6 and lower seal 7. The rigidity of the tray formed by the upper and lower shell is provided by the ribs of the upper shell 8 and the ribs of the lower shell 9. When connecting the received modules of slotted trays in the longitudinal Ohm direction, the joint tightness of the shells is provided by the longitudinal seal 10 (Fig. 2).

Assembling the slotted drain pan.

The proposed tray is assembled by two modules. The upper module consisting of a grill 1, housing 2, pipe 3. The lower module consists of an upper shell 4 and a lower shell 5, which are connected in any way that ensures tightness and strength. Next, the lower module is installed in the trench at the calculated level and filled with soil 11 or concreted. The upper module is joined with the lower by pairing the pipe with the hole in the upper shell, this connection is tight. Further, the upper module is installed in the design position and concreted. When installing the line of trays, the lower modules are first stacked and joined together, then concreted, then the upper modules are installed on them and concreted.

The design of the tray is such that the joint of the upper and lower modules movable during installation allows you to adjust their relative position both in height and in slope relative to each other. You can also ensure the tightness of the junction of the pipes on the basis of adhesive sealants, soldering, welding. In FIG. 3a-d show the main combinations of the position of the upper module relative to the lower. These options for installing trays solve almost any task of arranging a surface drainage system with various options for the vertical layout of the site.

The discharge of water from the slotted tray is carried out according to the same principle as in pipe sewage systems. The most common options are dumping into a well and into a larger pipe size.

Industrial applicability

The utility model allows on the basis of standard modules to produce slotted trays with various parameters for the depth of laying and slopes, adjustable on the top and bottom of the tray.

The inventive tray will be widely used for arranging surface drainage for areas with low and high traffic pedestrians and vehicles, as well as industrial enterprises and airports.
