CS201232B1 - Drainage collector of the large profile - Google Patents

Description

The invention solves the problem of designing and realizing sewage collectors of large profiles as construction products which, with frequent engineering networks embedded in the ground environment by means of a groove, either as a monolithic variant or as a pro-active prefabricated construction of prefabricated parts.

An important element of the requirements of protection and creation of the environment is the drainage of waste water through the sewerage network. The construction of the sewerage system requires considerable investment resources as well as long implementation times, which in particular result in technical and technological possibilities of construction supply activities. Consequently, the present invention is characterized by an attempt to develop such methods of implementation that will successfully replace conventional structures, primarily assembled from prefabricated components. In the following, the old idea of rdr production, but of higher technical parameters, continues to improve pipeline assembly technology, i. its laying and making connections. Taking into account the requirements for improving the physical properties of the surrounding earth environment, namely the subfloor, the pipe backfill and ultimately the backfill, are considered to be a greater measure of progress in the design and implementation of pipelines in the ground. The realization of the degree of compaction of these parts of the soil environment plays an important role, taking into account the often problematic suitability of soils for the required compaction and limiting the possibility of using available mechanisms. The above mentioned causes low efficiency - including heavy labor - of construction production in the field of underground lines, so

201 232 their design and construction of mainly large-profile pipelines is a natural effort for a more efficient solution.

The static analysis of the construction of the sewer collector of any shape implies the necessity of simultaneous assessment of the load-bearing capacity and the accompanying deformation of both essential parts, namely the sewer pipes and the earth environment. Contact deformation in their mutual interaction must therefore be an essential condition for design. It can be demonstrated by the model test of the rim ring that the oval deformation of the sewage collector towards the sides of the trench is a key task for the solution. The current pipeline design methodology is based on the assessment of the peak pressure on the pipe ring or component, but the load does not by far reflect the actual static behavior of the pipe ring, and so simplified pipeline designs do not take into account at all, or little, the lateral backfill resistance. There are plenty of examples of another extreme when it runs to a safer but uneconomic concreting of pipelines, which makes the pipe only a lost formwork. In the case of sewage collectors, for example, assembled from two prefabricated components, it is a joint construction with a curved or angled center only if modifications in the joint parts are effective to absorb horizontal forces. Without these modifications, the prefabricated components behave as simple beams both statically and economically very disadvantageous. Compaction or stabilization of the backfill is an advancement, but with the difficulty of the technological process, a reliably unreliable solution with a guarantee of quality uniformity by static calculation of the considered physical properties of the backfill, true, is less than that of growing soil.

These drawbacks are overcome by the large-profile sewer collector according to the invention, which is based on the fact that its articulated side struts are supported directly on the growing soil of the flank sides.

The combination of the own collector with segmented side struts increases the technical, technological and economical effect of the production of large-scale sewerage collectors on the level of rigid and articulated building structures. ,.

An exemplary embodiment of a drain according to the invention is shown in the accompanying drawings, in which: FIG. 1 shows a cross-section through the collector; FIG. 2 is a top plan view of the collector; FIG. 3 is a cross-sectional view of another embodiment, and FIG. 4 is a plan view of the variant of FIG. Third

Example 1

The construction process of the assembled large-profile sewer with large side struts consists of FIG. 1 and 2 of the trench depression, of the construction of the substrate 1, of the bearing and i

of the lower prefabricated part 2 of the sewer, from the wet joint J with the sealing insert, of the mounting of the upper prefabricated part 4, of the compaction of the lower part of the backfill 5, of the structured side struts 6 wherein the openings T between the struts allow natural long-term compaction of the lower part of the backfill by the groundwater or rainwater regime in relation to the modified upper part of the backfill 8 as well as the backfill 9 of the trench itself.

Example 2

A further possibility of using the invention is to combine a monolithic and assembled design of the pantograph and strut, true, with a proper static examination of the consequences of the free arrangement of the structure as a whole in interaction. For example, according to FIG. 3 and 4 - left monolithic, right-mounted variant - in the case of prefabricated struts 10 in the shape of the letter I, L or T, spaced on the compacted lower part of the backfill 11, fill the gap between the struts The prefabricated strips can be activated in a small amount of time by means of wooden wedges 13 between the second fronts and the collector, whereupon the rest of the joint is filled with grout concrete 14 · ^{in the} next step there is no distinction between individual combinations of solution methods.
