Description
Technical Field
The utility model relates to a municipal administration basis piping lane construction field, in particular to combine cable utility tunnel of drainage box culvert.
Background
With the high-speed promotion of the urbanization process in China, the available ground space of many large and medium-sized cities is nearly saturated, the scale of urban underground pipeline construction is continuously enlarged, but the management system for the underground pipeline construction is still imperfect, and the sustainable development of the urban construction is hindered. In recent years, the underground comprehensive pipe gallery which is continuously popularized and constructed is used as a high-efficiency intensive underground space structure, various municipal pipelines are concentrated and unified to be arranged underground, municipal traffic pressure caused by city development is effectively relieved, repeated excavation of roads when the traditional pipelines are overhauled is avoided, and the underground comprehensive pipe gallery is an important infrastructure for guaranteeing safe operation of cities. Among the utility tunnel, cable piping lane adopts the shallow channel mode construction that buries, builds in sidewalk or greenbelt below more, and the apron can be opened in piping lane upper portion setting, and its buried depth is shallower, and excavation easy maintenance can generally hold communication and power cable. Municipal drainage system also builds in the underground, will consider avoiding problem of piping lane and drainage system when piping lane design and construction.
Municipal administration water supply pipe, regeneration water pipe can cause the damage of pipeline because of soil erosion or ground subsides, and water supply and regeneration water pipe can lay in the cable piping lane because of pipeline under pressure, laying requirements such as no slope. Lay the water pipe in the cable piping lane to and the phenomenon of infiltration can appear in piping lane self structure, will be equipped with drainage system when the design of piping lane and construction. Drainage pipe (rain, sewage pipe) are gravity flow pipeline, and the burial depth is darker, and has the slope requirement, especially can produce flammable explosive gases such as methane and ammonia under the sewage pipe anaerobic environment, must install multiple gas detection equipment etc. when going into the corridor, so drainage pipe generally can not lay in the piping corridor. The cross section area of the drainage pipeline is relatively small, and the avoidance of the drainage pipeline is relatively feasible during the design and construction of the pipeline corridor; when drainage pipeline low reaches are crossed, because the water yield is great, can adopt the box culvert form usually, the cross-sectional area of box culvert is great, and the degree of difficulty of dodging of piping lane and box culvert is great. In addition, when the drainage system is arranged at the bottom of the pipe gallery, a relatively thick bottom or a space which can be utilized by the bottom is required to be arranged by the downward projection of the bottom, so that the common avoidance method is that the pipe gallery and the box culvert are transversely arranged side by side, the method can increase the transverse occupied area width of the underground structure, and can also cause the movement and the modification of other underground pipelines and increase extra engineering investment.
