The present invention relates to a base provided with a reverse stream corridors. Corridors provided a reverse stream basis of the present invention, stream slopes (1) or the bottom surface (2) of any one of the trench portion is formed excavation 10 and selected; Is formed in the top and bottom tapering, lower portion and is inserted into the excavated section 10, the upper part is itdoe consists of a number of natural stone (21) installed without protruding into the trench portion 10, the upper, adjacent Natural stone 21 has a contact portion 22 is spaced apart points in the upward direction, which abuts contact with each other is formed, the contact portion (22) lower portion is formed with a bottom spaced portions 23 spaced apart from each other from the digging portion 10 , and the contact portion 22 is an upper natural stone installation portion 20 is formed with spaced apart upper section 24 with each other; Itdoe is filled with earth and sand is formed in the lower portion spaced from part 23, the trench portion 10, earth and sand-filled portion 30, which is filled to the top to form a passage between the eco-contact portion 22 from the upper surface (31); And the upper and the spaced portion 24 it is formed is filled with a large number of aggregate, and the upper surface consists of a flat, aggregate charging part 40 that a gap is formed between the aggregate; It is installed on the upper portion of the aggregate filling section 40, a concrete foundation 50 which is inserted into the reinforcement; is configured to include a. According to the invention, that prevents the corridors that slopes blocks deposits into the gap provided in the form to the lower being the concrete base an upper portion of the concrete base flowing into the corridors, and provided with the above corridors as well as corridors by the concrete base is installed on top of the stone that forms a and maximize prevent flow of the foundation by the force of the water flow and slopes block installed in the river slopes or on the floor by the weight of the concrete foundation and stone, installed the aggregate between natural stones and the concrete base may be an ecological passage after the construction remain stable to prevent separation of the natural stone in the basic structure to form the corridors made to an integral structure to achieve the aggregate and the natural stone and integrally through a wet construction, and further , by installing a top and bottom is tapered top and the bottom of the stone is formed becomes to achieve a respective structure protruding up and down the lower side as is forms a structure that is inserted into the ground, the upper side as is increasing the contact area with the concrete in contact with the aggregate is poured it is possible to increase the adhesive strength of natural stone and concrete as possible. ;
