Micro pile and assembly foundation reinforcement structure member for pier

摘要

The present design is such that the field micropile outside the neighborhood of the pier in the ground, by installing prefabricated brackets on the field micropile to enhance jinaeryeok the soil while preventing bed scour around the pier one to stabilize the pier It relates to a pier foundation prefabricated reinforcement structure for a scene using the micropile and prefabricated brackets.; The perforations are designed to be symmetrical with perforations at a predetermined diameter and depth in the ground near the pier after digging the trench and; Wherein the insert reinforced by a predetermined depth into the hole and grouting the curing site and micropile; Installed on top of the reinforcement provided in the field micropile and a fixing portion to be connected to the prefabricated brackets; At the same time as the horizontal plane of the assembled bracket connected with a bolt fastened to bolt holes the fixing portion provided around the pier, and the vertical surface of the assembled bracket connected to the anchor in the hole formed at the lower end of a pier of a number which is formed generally by a right triangle prefabricated bracket; An L-shaped steel, and interconnecting the modular bracket plurality dog ​​installed around the pier; Non-shrink mortar between the vertical plane and the angle of intersection of the gap and the assembled bracket between the horizontal plane and the fixing portion of the bracket and which is prefabricated cast-in-place curing to the prefabricated brackets and; Through the remaining soil digging between the prefabricated brackets with a configuration in which the laying gravel or crushed stone of different sizes to prevent scour around the pier and to enhance jinaeryeok of soil there is an advantage that can be stabilized of the pier.
