Porous rectangular pipe jacking and open and underground excavation connection pipe gallery joint and construction method thereof
The invention discloses a porous rectangular pipe jacking and open and underground excavation connection pipe gallery joint. The joint comprises pipe jacking gallery sections, a working well section,a connecting transition section and an open and underground excavation pipe gallery section which communicate in sequence, wherein the pipe jacking gallery sections are formed by sequentially-connected pipe joints, at least two pipe jacking gallery sections are arranged in parallel, one end of a pipe gallery wall in a working well is connected with a connecting triangular column located in the connecting transition section, the connecting triangular column is in a vertical column shape, the end, close to a clamping wall body, of the connecting triangular column is wider than the other end faraway from the clamping wall body, the two sides of the end, away from the clamping wall body, of the connecting triangular column coincide with the two sides of a wall of an open and underground excavation pipe gallery correspondingly, a transition section wall, an inner lining wall, a top plate and a bottom plate of the working well are coated with waterproof coiled materials, and the waterproofcoiled materials extend from the outer side of the transition section wall to the end, close to a pipe joint, of the inner lining wall. Smooth connection between an open excavation pipe gallery and aporous pipe jacking pipe gallery is achieved, the structure is safe and reliable, the waterproof method at a weak position of closing of the working well and a pipe joint of pipe jacking is simple andeasy to implement, and water is prevented from entering a joint pipe gallery.
本发明公开了一种多孔矩形顶管与明暗挖交接管廊接头，包括依次连通的顶管管廊段、工作井段、衔接过渡段、明暗挖管廊段；顶管管廊段由依次连接的管节形成且并行设置至少两段，工作井内管廊墙体的一端连接有位于衔接过渡段的衔接三角柱，衔接三角柱为沿竖向的柱状，衔接三角柱靠近夹墙体的一端宽于远离夹墙体的一端，衔接三角柱远离夹墙体的一端两侧分别与明暗挖管廊的墙的两侧重合；工作井的过渡段墙、内衬墙、顶板、底板的外侧包覆有防水卷材，防水卷材自过渡段墙外侧延伸至内衬墙靠近管节的一端。实现了明挖管廊与多孔顶管管廊的平顺衔接，结构安全可靠；在工作井与顶管管节收口的薄弱位置的防水做法简单易行，防止水进入到接头管廊内。
