STRUCTURE FOR PREVENTING INTERFERENCE OF FLANGE IN UNDERGROUND WATER EXHAUST PIPE}

The present invention relates to a stopper of the groundwater intake pipe flange, and more particularly, the flange of the intake pipe and the end of the inner casing pipe in the process of installing or lifting the intake pipe inserted into the excavated heart well to collect the groundwater The present invention relates to a structure for preventing the catchment of groundwater intake pipe flanges to prevent jamming caused by interference.

In general, when looking at the internal structure of the heart excavated to collect underground water, as shown in Figures 1 and 2, the surface of the rock is excavated to the rock layer (12) using a rocker of a predetermined thickness and then weathered rock layer After installation of the large-diameter outer casing pipe 1 and the outer casing pipe 1 installed to prevent the collapse of 10, the rock bed 12 is again excavated to penetrate the water vein 13 of the groundwater. Groundwater core inner wall which is installed to secure space for filling filler 9 such as gravel and sand in order to prevent ground depression and maintain constant flow rate of groundwater in rock vein after excavation (17), an inner casing pipe (2) inserted into the outer casing pipe (1) so as to maintain a predetermined gap with the outer casing pipe (1), and the groundwater vein (13) under the inner casing pipe (2). Surface water in the space between the strainer pipe (3) and the inner casing pipe (2) and the inner wall of the groundwater core (17) installed to prevent the inflow of soil and foreign matter into the groundwater and to maintain the proper flow rate. 11) is installed to be connected to the concrete (4) injected and cured to prevent the inflow of foreign substances such as, the heart pump (5) installed in the inner casing pipe (2), and the heart pump (5) The groundwater 13 pumped by the heart pump (5) is composed of a collecting pipe (6) to be moved. The cardiac well pump 5 is driven by the upper and lower level sensors 7 and 8 provided in the collecting pipe 6.

According to the groundwater core structure in which the water collector is installed, the groundwater flowing through the water vein 13 is collected into the strainer pipe 3 and the inner casing pipe 2, and when the core pump 5 is operated, the ground pipe 6 is collected. Through the ground water is supplied to the ground and the discharge amount of the ground water is adjusted in accordance with the signal of the upper and lower level sensors (7, 8). Reference numeral 14 in FIG. 1 denotes a core information arc cover for opening and closing the upper end of the outer casing pipe 1, 15 is a core well inlet cover, and 16 is a check valve installed at the upper end of the water collecting pipe 6.

However, in the general water harvesting device having the structure as described above, if the excavation to the deep position of the basement using a landing gear is preferably excavated vertically from the ground, in practice, the degree of straightness is lowered to some extent bend excavation This is a general phenomenon. Therefore, the inner casing pipe 2 provided inside the core is also bent along the curved core inner wall 17. In this case, the inner casing pipe (2) is not in close contact with the lower strainer pipe (3), the gap is generated while the lower end of the inner casing pipe (2) is exposed. In addition, the construction of the inner casing pipe (2) is often exposed as it is often the case of finishing the construction only by the inner casing pipe (2) without installing the strainer pipe (3) at the bottom in the actual landing process.

As described above, when the inner casing pipe (2) is installed, several water collecting equipment is installed therein, among which the core pump (5) connected to the water collecting pipe (6) and the water collecting pipe (6) is assembled in advance on the ground. It is installed while being pushed into the inner casing pipe (2).

However, in the process of installing the collecting pipe 6 or lifting it for recovery thereafter, as shown in FIG. 2, a flange 6a connecting the collecting pipe 6 is provided at the end of the inner casing pipe 2. The operation is very difficult because of the frequent cases. In particular, this case is further intensified when the heart is bent.

In addition, when excessive force is applied to lift the collecting pipe 6 while the collecting pipe 6 is caught by the inner casing pipe 2, the inner casing pipe 2 and the collecting pipe 6 are not only damaged. In this impact, the expensive cardiac pump 5 connected to the bottom of the water collecting pipe 6 is separated and falls, thereby making it difficult to recover.

The present invention has been made in consideration of the above-described conventional problems, and is intended to provide a structure for preventing the catchment of groundwater intake pipe flanges, which prevents the phenomenon that the flange of the intake pipe is caught by the inner casing pipe when installing or lifting the intake pipe. .
