(Technology)

The present invention relates to a drain trench unit, and more particularly, to a drain trench unit that can prevent material separation from occurring between the bottom concrete and the trench in which the drain trench is constructed.

(Background)

It is common to establish a drainage trench for collecting sewage and discharging it to sewage on the floor where sewage needs to be treated, such as a parking lot floor.

One way to build drainage trenches is to build drainage trenches directly on site by laying bricks when placing concrete on the floor.However, this construction method is low in productivity and does not fit well in the resulting trenches. This can cause various problems, such as the construction of a drainage trench by manufacturing a standardized drain trench unit from a factory, not a construction site, and assembling these ready-to-use drain trench units on the floor when placing floor concrete. Technology is widely used, such drainage trench units are made of a variety of materials, such as concrete, metal, plastic synthetic resin.

One of the problems in constructing drainage trenches with drainage trench units is the separation of material between the bottom concrete and the trench, which are dissimilar materials, resulting in a gap along the interface between the trench and the concrete. The presence of foreign matters will shorten the life span of the trenches, as well as reduce hygiene and cleanliness.

This problem of material separation is caused by the heterogeneity of the bottom concrete and the trench concrete even when the drain trench unit is made of concrete, but especially when the trench unit is made of a heterogeneous material different from the bottom concrete such as plastic composite resin. Do.

One of the difficulties encountered in constructing drain trenches with drain trench units is that a great deal of time and effort must be spent connecting the units with the appropriate gradients without gaps.

That is, in the conventional method of connecting the drainage trench unit, a method of connecting only the unit and the unit to be in contact with each other when placing bottom concrete without forming a separate connection structure in the unit and forming a bolt hole at the end of the unit Although there was a method of interconnecting adjacent units by bolt assembly, the former method only depended on the operator's skill in connecting the units and forming drainage gradients. There were many defects of the, and the latter method was less leaking and drainage than the former, but there was a problem that it is very cumbersome to connect the unit by bolting.

SUMMARY OF THE INVENTION An object of the present invention is to provide a drainage trench unit that can prevent material separation between the bottom concrete and the drain trench installed therein, whereby a gap is generated between the bottom concrete and the drain trench by the material separation phenomenon. It is to solve the above-described problems that can be.
