Description

Multi-channel element with hermetic seal

Field of technology

The presented technical solution of multichannel elements with hermetic sealing finds use in the field of construction, construction of technical infrastructure - line construction.

Modular elements of multi-channel elements with hermetic sealing are a kit for easy and fast creation of durable and permanent routes of underground physical infrastructure, as well as paths for the passage of bridge structures, tunnels, etc. with a guaranteed service life of 50 years.

They have high load resistance, allow the installation of high capacity technical infrastructure in a small space, the construction of multi-channel routes is fast and very flexible.

The subject technology of multi-channel elements with hermetic sealing can be used as an alternative to the construction of concrete cable ducts, which are structurally, time-consuming and financially demanding.

It is an ecological product with a fast return on investment.

Prior art

Previously known modular multichannel elements are made of high density polyethylene (HDPE), the shape of a hollow base body of elongated shape with a rectangular or square cross-section, the inner space of which is divided by at least one partition extending in the longitudinal direction and circumferentially extending reinforcing ribs , wherein neck elements are formed on the front sides of the base body for connection to the base bodies of adjacent multichannel elements.

With the Multichannel elements used so far, the interior of the multichannel elements is not sufficiently protected against the ingress of water and dirt.

The task of the present technical solution is therefore to find such a construction of the Multichannel element which, after assembly, will be resistant to the ingress of water and dirt in comparison with the hitherto known Multichannel elements. Compliance with this requirement is directly related to the type of accompanying elements used, eg cable chambers. Other indisputable advantages of this product include a comprehensive adaptation of the system to the given needs in all directions. It is possible to create straight sections, bends, changes in height level, use side branches, transitions, reductions when switching to separate pipes with a diameter of 110 mm or combine with other bearings. A special bending part allows a 3 ° deflection, while a 90 ° bend can be achieved over a length of 6.4 m.

The essence of the technical solution

The solution of the requirement for fast construction of watertight cable ducts with the use of multichannel elements is the presented solution with the help of multichannel elements with hermetic sealing. This system is resistant to water pressures up to 0.3 bar. The whole system is suitably complemented by plastic or concrete access chambers. These then allow the inspection, replacement or installation of new cables in existing cable routes. They can serve as control, input and output and / or serve for crossing and branching individual cable routes.

The described solution creates the preconditions for the interior of multichannel elements with hermetic sealing to be protected against the ingress of water and dirt.

The improvement of the product consists in the fact that the individual parts of the multichannel elements with hermetic sealing are changed by the construction, namely by the extension of the circumferential flange (Fig. 1; Fig. 2, Fig. 3). The individual elements are connected in a circumferential flange, where an inner resilient circumferential seal is arranged, behind which a circumferential step is formed in the longitudinal direction of the base body, which is formed on the inner circumference of the base body, the clear dimensions of the circumferential flange with the inner resilient circumferential seal being complementary to radial dimensions of the circumferential shoulder.

By means of the mentioned improvements, the protection against the ingress of water and impurities into the inner space of the Multichannel composed of multichannel elements with a hermetic seal is improved.

The interconnection of the individual multichannel elements with the hermetic seal is mechanically ensured so that a flexible clamp (Fig. 3) rests on the edge of the circumferential flange remote from the front of the base body, which connects this circumferential flange with a circumferential rib formed in the axial direction behind the circumferential shoulder bodies of an adjacent Multichannel element.

Explanation of drawings

The utility model is explained in more detail with the aid of Figures 1, 2 and 3 below.

Giant. 1 The technical solution is further illustrated in FIG. 1 by a schematic diagram showing the shape of a multichannel element with a hermetic seal.

Giant. 2 The technical solution is further illustrated in FIG. 2, which shows a schematic drawing of a bending part with a 3 ° deflection.

Giant. 3 The technical solution is further illustrated in FIG. 3, which shows a hermetic seal.

Example of implementing a technical solution

It is to be understood that the specific example of an embodiment of the particular solution described is given by way of illustration only, not as a limitation of the exemplary embodiments of the utility model. Those skilled in the art will find many more examples of embodiments of a utility model.

Fig. 1 schematically shows a view of multi-channel elements, each of which consists of a body of a multi-channel element 1 in the shape of a hollow prism or a block, which is made of high density polyethylene (HDPE). In the exemplary embodiment shown, four perpendicularly oriented partitions 6 are used, which thus divide the inner space of the base body into nine channel chambers. Reinforcing ribs are formed on the circumference of each base body as a whole with these base bodies, which run around the entire circumferences of the base bodies in a plane perpendicular to the longitudinal axis of these base bodies. The purpose of these reinforcing ribs is to protect the base body itself against mechanical damage. Furthermore, FIG. 1 shows a circumferential flange 7 which is formed at the end of the body of the multichannel element E

Fig. 2 shows a bending part which allows a 3 ° deflection, while a 90 ° bend can be achieved over a length of 6.4 m.

Fig. 3 shows on an enlarged scale a longitudinal section of the joint of adjacent base bodies. It can be seen in the section that a shaped seal 2 is placed on the circumferential shoulder, behind which a circumferential sealing step with a straight seal 3 is formed in the longitudinal direction of the multichannel element body 1. Water and dirt tightness is ensured by the use of a circumferential shaped seal 2 and steel clamps 4 with a tightening. screw 5.
