Structure for transversely-crossing underground passage of urban road and construction method thereof
The invention relates to a structure for transversely-crossing an underground passage of an urban road. The structure for transversely-crossing the underground passage of the urban road comprises a pipeline in a soil layer disposed under the road, the pipeline comprises pipe sections sequentially connected in a passing length direction, a forward section is arranged on the pipe section on end partof one end of the pipeline, an operating section is arranged on the pipe section on end part of the other end, a ring of water injection cavity is formed in the inner part of the end, located on theend part of the pipeline, of the forward section, a water outlet communicating with the water injection cavity is formed in the outer surface of the forward section, a water injection source communicating with the water injection cavity is connected into the forward section, water collection cavities are formed in the side walls of the pipe sections, water inlet communicating with the water collection cavities are formed in the outer walls of the pipe sections, water collection cavities between adjacent pipe sections communicate with one another, a water pump is arranged at the end, located atthe tail end of the pipeline, of the operating section, and the water pump communicates with the water collection cavities of the operating section. The structure for transversely-crossing the underground passage of the urban road has the effect of facilitating the pushing construction of the pipe sections in the soil layer with low water content.
本发明涉及一种横穿城市道路地下通道的结构，包括设置在道路下方的土层中管道，所述管道包括沿其通长方向依次连接的管节，位于管道一端端部的管节为前进节，另一端端部的管节为操作节，前进节位于管道端部的一端内部中设置有一圈的注水腔，前进节的外表面设置有与注水腔连通的出水口，所述前进节的内部连接有与注水腔连通的注水源，所述管节的侧壁中设置有集水空腔，所述管节的外壁上设置有与集水空腔连通的进水口，相邻管节之间的集水空腔连通，操作节位于管道末端的一端设置有水泵，所述水泵与操作节的集水空腔连通。本发明具有便于管节在低含水率的土层中被推进施工的效果。
