この発明は暗渠排水の施工方法に関し、暗渠排
水の分岐部においてブロツクの接続を非常に行な
い易くすると共に接続が確実で分岐部での排水路
の偏りをなくせるようにしている。[Detailed Description of the Invention] The present invention relates to a construction method for underdrain drainage, which makes it extremely easy to connect blocks at the branching part of the underdrain drainage, and also makes the connection reliable and eliminates unevenness of the drainage channel at the branching part. ing.

暗渠排水の施工が必要となる。 Moisture in the soil is generally essential for crop growth, but in fields in low-swamp areas with high groundwater levels or fields that are heavy and dense and have poor permeability, heavy or long rains can cause excess moisture in the soil. This causes many problems such as poor crop growth, poor germination, and disease outbreaks. For this reason, it is necessary to construct an underdrain to ensure proper drainage of the soil.

には不適当なものであつた。 In the past, to improve the drainage of soil, underground drains were created by burying knotted bamboo pipes, brushwood, etc. in trenches dug in the ground, but bamboo pipes and brushwood were not only inconvenient to handle, but also difficult to handle. The drawback was that it was susceptible to corrosion due to the action of bacteria in the soil. For this reason, metal pipes, clay pipes, etc. are buried in place of bamboo tubes and bamboo pipes, or structures are constructed with stones, bricks, concrete, etc., but these are expensive and water can only flow in from the ends of the pipes. Therefore, it was unsuitable for use as a culvert to improve drainage in large areas such as agricultural land.

するものである。 Therefore, recently, underdrain drainage blocks made of hard synthetic resin foam have been used with good results because they are easy to construct, practical, lightweight, and have excellent corrosion resistance and elasticity. In particular, in the construction method according to the present invention, the above-mentioned blocks can be connected simply, quickly and reliably at the branching part of the underdrain drainage, and moreover, the drainage path at the branching part can be made even. That is, the construction method involves inserting the required length of the end of a synthetic resin underdrain block, which has drainage grooves in the longitudinal direction on both sides of the central vertical wall, and creating a connection opening that can be connected. Connect the underdrain drainage block to T using T-shaped or cross-shaped connection covers formed on three or more sides.
When connecting in a type or cross shape, the end of the underdrain drainage block inserted from the remaining connection opening perpendicular to the ends of the underdrain drainage block inserted from the two opposing connection openings. It is characterized in that the underdrain drainage blocks are connected on three or more sides so that the drainage channels of each underdrain drainage block are directly connected.

献できること多大なものである。 As described above, according to the present invention, underdrain drainage blocks made of synthetic resin having drainage grooves in the longitudinal direction on both sides of the central vertical wall can be used to divide the required length of the block into locations where branching is required. Sawo T
When the block is inserted into the connection opening of a connecting cover in the shape of a cross or a cross, and connected, there is a gap between the ends of the block inserted through the two opposing connection openings, which is perpendicular to this. With the simple operation of inserting the end of the block inserted through the connection opening, the underdrain drainage blocks can be arranged in a T-shape or cross-shape on three or more sides so that the drainage channels of each underdrain drainage block are directly connected. Because of the construction that can be connected, as mentioned above, the drainage channels formed by the left and right rows of the underdrain drainage blocks can be formed without being biased, making it possible to form an even drainage channel, and construction with smooth drainage flow can be achieved.
In addition, this invention enables construction using the above-mentioned connection cover to quickly and reliably form the branching part of the underdrain drainage, and further strengthens the reinforcing properties at the branching part. It is a great thing to be able to contribute to the spread of technology.
