Abstract

FIELD: building transition main-pipelines and road banks in rough terrain. SUBSTANCE: water releasing construction has bank layer 1 with draining sublayer in the base in the form of non-woven synthetic material 2 and filtering part 3 placed under them. The filtering part is made in the form of horizontal plates positioned one over other. The plates have vertical passages and ledges on their lower surfaces. The ledges are oriented alternatively in plane, Vertical passages are placed between the ledges. EFFECT: effective drainage. 2 cl

Description

 The invention relates to construction and can be used in the construction of crossings of pipelines and embankments in rough terrain.

A culvert is known that contains a stone draft filtering the embankment, consisting of stones whose sizes range from 0.1 to 0.5 m. Moreover, stones with a large size make up at least 60% (by weight), and stones of a smaller size up to 10 % [1]
A disadvantage of the known structure is the complexity of selecting the ratio of the size of the stones and in this regard, low labor productivity, as well as the difficulty of ensuring the estimated throughput of the structure.

Closest to the proposed technical essence is a culvert containing a mound with a draining layer in the base in the form of a non-woven synthetic material and a filter part located below it [2]
The disadvantage of this technical solution, taken as a prototype, is also the difficulty of ensuring the estimated throughput of the structure.

 The technical result is an increase in the efficiency of the culvert through the creation of labyrinth culverts and the possibility of the estimated throughput of the water flow.

 In FIG. 1 shows the proposed culvert, General view; figure 2 view along arrow a in figure 1.

 The culvert (see figure 1) contains a layer of embankment 1 of mineral soil, non-woven synthetic material (HCM) 2 and a filter layer made in the form of cellular perforated blocks 3, which have a variable cross-section. Blocks 3 are flat perforated plates 4 with protrusions 5 and holes 6, stacked on top of each other (see figure 2). Blocks 3 are a cellular structure with channels for water passage. The arrangement of cells in a checkerboard pattern as if imitate a stone sketch. Holes 6 in blocks 3 provide drainage of water from the embankment, which protects it from erosion, and a layer of non-woven synthetic material (HCM) 2 prevents soil from filling the filter bed with soil 1. With this design of the culvert structure, the water seeping through the narrow labyrinth channels does not freeze, and the location of the channels at different levels provides fluid filtration and prevents the structure from clogging.

 Lightweight building structures made of various materials, wood, plastic, expanded clay concrete, etc. can be used as cellular blocks. They can be manufactured in the factory from industrial waste in an industrial way, it is easy to erect, and if necessary, it is easy to disassemble the building from clogging.

 The use of the invention will ensure the design flow rate of water through the filtering mound at negative outside temperatures.

Claims (1)

 A water inlet structure containing an embankment with a drainage layer in the base in the form of a non-woven synthetic material and a filter part located below them, characterized in that the filter part is made in the form of plates placed on top of one another and horizontally arranged with vertical channels and protrusions on their lower surfaces, these protrusions are oriented in a staggered plan, and vertical channels are located between the protrusions.
