摘要
The present invention is to sewer, water, roads, rivers and protection structures for sewer drainage construction installed in the landfill leachate discloses a. Sewer according to the designed, water, roads, sewer structures for protection to be installed in rivers and landfill leachate drainage construction has to be compatible with the vertical placement while having a predetermined spacing on the floor of the cave, which is when the Tobu gulto, the inner surface roughness ( ) and struts are formed; The upper surface is coupled to the support groove part is formed is the lower surface of the sewage pipe insertion, the unevenness of the crutch to engage the opposite side surfaces irregularities ( ) is formed in the lower concrete block is supported on the crutch; If there are formed the first engaging groove portion is opposite to the coupling groove of the lower concrete block to be inserted into the upper outer surface of the sewage pipe, the upper surface, the other of the water supply pipe is buried in the upper portion of the water supply pipe is inserted so that the support consists of a second engaging groove portion is formed in the upper concrete block. Therefore, as water supply and drainage pipe is buried such that they cross each other by the upper concrete block and the lower concrete block to be prevented from being damaged is prevented from being in contact with each other as well, there is an effect to be prevented from the ground subsidence.
