本考案は、傾斜地盤の地表水及び地下表層流水
を人為的に排水して該傾斜地の洗掘等を阻止する
ための埋設排管に適用して好適な排水管に関する
ものである。[Detailed description of the invention] The present invention relates to a drainage pipe suitable for use as a buried drainage pipe for artificially draining surface water and underground surface water on sloped ground to prevent scouring of the sloped land. It is something.
土砂地盤中に中空濾過管を埋設し、地下流水を
人為的に排水する方法は既に種々案出されている

掘・掃流を伴なつて土砂が下流に流されてしま
い、甚大な惨事をひき起こしてしまう。 Various methods have already been devised to artificially drain underground water by burying hollow filtration pipes in the sandy ground, but the amount of water that flows down the ground during heavy rainfall is large, and on steep slopes, so-called flash floods can occur. Disasters cannot be prevented. In other words, when there is a small amount of rainfall, precipitation permeates underground and forms a groundwater system, so by burying conventional hollow filtration pipes, softening of the ground and landslides can be partially avoided. However, in times of heavy rainfall, the amount of water that flows down the surface of the earth is much greater than the amount that permeates into the ground, and the water pressure causes the surface to scour and sweep away, causing sediment to be washed downstream. , causing a huge disaster.
本考案はかかる点に鑑み、地下表層流水は勿
論、大量降水時に生ずる地表流水を一挙に排水す

る目的とする。 In view of these points, the present invention has been developed by constructing a cylindrical body with a drainage guide plate partially exposed on the ground surface, in order to drain not only underground surface runoff but also surface runoff that occurs during heavy rainfall. The main objective is to propose a drainage pipe that eliminates these drawbacks.

て切溝１ａに挿入するようにしてもよい。 FIG. 1 is a perspective view showing an example of the drain pipe of the present invention. Reference numeral 1 indicates a cylindrical body having a circular cross section, which is made of synthetic resin or metal. Cylindrical body 1
A cut groove 1a is formed in the axial direction in the upper part of the pipe, and a drainage guide plate 3 is press-fitted into the cut groove 1a. In this case, by using a vinyl chloride pipe for the cylindrical body 1, internal strain is generated in the circumferential direction, so if this strain is utilized for insertion, no particular adhesive is required.
Of course, this does not preclude the use of adhesives in combination. The drainage guide plate 3 has a structure in which a nonwoven fabric 5 is bonded to the front and back sides of a net 4 made of synthetic resin such as vinyl chloride. The width W can be within twice the diameter of the cylindrical body 1 in consideration of the withstand pressure of the ground when buried in the trench 2a excavated in the ground 2. and full width W
Insert 1/4 of it into the cylindrical body 1, as shown in Fig. 2,
A drainage guide plate 3 is provided so that 1/2 to 1/4 of 3/4 of the total width W protrudes from the cylindrical body 1 and is exposed from the ground surface 2b. The cylindrical body 1 may have not only a circular cross section but also an elliptical or polygonal cross section. The thickness of the drainage guide plate 3 can be increased by making the net 4 thicker considering the expected amount of drainage, but two or more guide plates 3 of a certain thickness may be stacked and inserted into the groove 1a. You can do it like this.

In this example, a plurality of rows of drainage guiding plates 3 are provided radially. With this configuration, more surface water can be dammed,
Therefore, flash flood disasters can be prevented and a larger amount of water can be introduced into the cylindrical body 1.

も少なくなる。 FIG. 4 is a sectional view showing still another example of the present invention. In this example, the structure is almost the same as the example in FIG. It was inserted to near the ground surface.
According to such a configuration, even if the flowing water that flows down the ground surface and is caught by the drainage guide plate 3 contains finely divided mud, the sand 7 prevents its infiltration, prevents clogging, and ultimately improves the long-term lifespan. It can withstand use and requires less maintenance.

The water flowing down the surface of the slope is partially dammed by the drainage guide plate, passes through the drainage guide plate, and is collected in the cylindrical body, thereby preventing soil from scouring the ground surface. At the same time, water that has permeated into the soil is also collected in the cylindrical body through the drainage guide plate at the surface stage. Therefore, it is possible to prevent the ground from becoming soft during rainfall, and disasters such as flash floods and landslides can be prevented.
