SU1232727A1 - Water withdrawal drain pipe - Google Patents

Description

The invention relates to the construction of drainage systems for airfields of highways, etc., and can be used in industrial and civil construction for draining construction sites and territories.

The purpose of the invention is to increase reliability in operation.

Figure 1 shows the proposed device, a General view; figure 2 - section aa in figure 1.

The drainage drainage pipe contains flexible vaulted elements 1 with a tray 2 of flexible drainage material, for example, dornit. The lateral parts of the flexible vaulted elements 1 are made with slots 3, through which the locking straps 4 with the stops 5 are passed.

The joints between the links 7 and 8 of the drainage pipe are wrapped with a strip of 9 flexible synthetic drainage material. The pipe is installed on the sand pillow 10 of the base of the trench and is filled with drainage soil 11.

The drainage drainage pipe works in the following way.

When crossing the trench of the aquifer of the soil, water flows through the draining soil 11 into the lower part of the trench. As the level of water accumulating at the bottom of the trench rises above the plane of the bottom of tray 2, water begins to drain through the surface of the bottom of tray 2 and slot 3 into the drainage drainage pipe and then goes down the slope to the collector.

From the pressure of the draining soil 11, tensile stresses occur in the panels of tray 2, and in flexible vaulted elements 1 deformations are possible. Fixing straps 4 perceive some of the tensile stresses, unloading the panels of tray 2 and giving the pipe structure greater strength that allows keep her preset shape. In this case, the stops 5, located at the ends of the fixed strut 4, passed through the slots 3 in the side surfaces of the vaulted links 7, press the edges of the panels of the tray 2 against them, ensuring that they fit snugly and prevent the soil from entering the cavity of the pipe.
