Description
Technical Field
The invention relates to the technical field of hydraulic engineering, in particular to a embankment structure crossing an existing underground structure.
Background
The embankment engineering refers to a water retaining building built along the edges of a river, canal, lake, coast or flood area, flood diversion area, reclamation area. Along with the continuous occurrence of extreme weather, the construction of flood control systems in China is more and more important, and the role of embankment engineering is more prominent. However, for river courses with wider river beaches, the condition that newly built embankments cross existing underground structures such as inverted siphons, water pipelines, natural gas pipelines and the like often occurs, and at this time, the embankment body is filled and constructed to cause excessive stress and foundation settlement of the existing underground structures in a coverage range, so that the safety and normal operation of the existing underground structures are affected. For such situations, at present, a treatment mode of dismantling and rebuilding existing underground structures in a covered range is mostly adopted, namely, original underground structures in a dike influence range are dismantled, then the original underground structures are designed again after the dike is covered, necessary basic treatment measures are set, and structural parameters are increased so as to meet the requirements of the dike. Since demolition and reconstruction of the original underground structure must be performed in its off-line state, it is difficult to determine its off-line period during the embankment construction period, and this uncertainty factor has a serious influence on the implementation of the embankment project.

the embankment structure crossing the existing underground structure comprises
The embankment is of a two-section structure arranged above the existing underground structure, and the axis of the embankment is crossed with the axis of the existing underground structure;
the abutment is arranged at the end part of the embankment, pile groups are arranged at the bottom of the abutment, and bridges positioned above the existing underground structures are arranged between the abutment;
the flood control wall is arranged between the abutment blocks along the axis of the embankment and is positioned on one side of the embankment, which faces the water;
the bottom plate is arranged at the bottom of the flood control wall, one end of the bottom plate extends to the upstream surface side of the embankment, and the other end of the bottom plate extends to the upstream surface side of the embankment;
the cover is arranged at the same height as the bottom plate and is connected with one end of the bottom plate, which is positioned on the upstream surface of the embankment;
the impervious walls are respectively arranged at two sides of the existing underground structure and are L-shaped structures which are arranged along the paved edge and are turned to the lower part of the embankment and extend along the axial direction of the embankment.
The abutment is a gravity abutment which is horizontally arranged at a distance of 4.5-5.5 meters from the existing underground structure and is used for reducing the influence of construction on the existing underground structure.
The flood control wall is of an empty box type wall structure and is made of reinforced concrete doped with high-performance polypropylene fibers, two sides of the flood control wall are rigidly connected with the abutment, and the bottom of the flood control wall is connected with the bottom plate in a water-stopping mode, so that the flood control wall has supporting and flood control functions.
The weight of the bottom plate is equivalent to the original soil covering weight above the existing underground structure, and the bottom is 1.0-2.0 meters higher than the upper edge of the existing underground structure, so that the bottom plate is used for preventing seepage in the horizontal direction, and the seepage-proofing length of the structural foundation is increased.
The bottom plate is connected with the flood control wall, the abutment and the covering by water stop, so that a horizontal seepage prevention structure is formed.
The diaphragm wall comprises cement stirring piles which are continuously arranged and mutually sleeved, the diaphragm wall is mutually perpendicular to the paved layer, and the joint of the diaphragm wall and the paved layer is covered with cement soil or clay, so that a vertical diaphragm structure is formed, and the diaphragm wall and the horizontal diaphragm structure jointly act to effectively prevent lateral infiltration at two sides of the diaphragm wall.
The embankment structure crossing the existing underground structure can be constructed in a state that the existing underground structure keeps normal operation, so that the defect that the construction progress of the traditional embankment structure is influenced by the existing underground structure is overcome, and the space contradiction caused by crossing of a newly built embankment and the existing underground structure is solved; secondly, the embankment structure disclosed by the invention does not influence the safety of the existing underground structure, and has flood control and upper traffic functions while ensuring the functional continuity of the embankment.

As shown in fig. 1-4, the dike structure crossing the existing underground structure according to the present invention includes a dike 1 with a two-stage structure disposed above the existing underground structure M, where the axes of the dike 1 and the existing underground structure M are disposed in a crossed manner, and in this embodiment, the axes of the dike 1 and the existing underground structure M are perpendicular to each other.
The abutment 2 is arranged at the end part of each section of embankment 1, the bottom of each abutment 2 is provided with a pile group 3, and a bridge 4 positioned above the existing underground structure M is arranged between the abutment 2. In general, the abutment 3 is a gravity abutment, which is horizontally spaced from the existing underground structure M by 4.5-5.5M, for reducing the influence of construction on the existing underground structure M. The bridge 4 is of a single-span structure, and is convenient to pass.
In order to play a role in supporting and flood control, a flood control wall 5 extending along the axial direction of the embankment 1 is arranged between the piers 2, the flood control wall 5 is positioned on one side of the upstream surface of the embankment 1, a hollow box structure is made of reinforced concrete doped with high-performance polypropylene fibers, two sides of the hollow box structure are rigidly connected with the piers 2, and the hollow box structure is cast and implemented at the same time, and the bottom of the hollow box structure is connected with a bottom plate 6 in a water-stopping manner.

Further, the weight of the bottom plate 6 is equivalent to the original soil covering weight above the existing underground structure M, and the bottom is 1.0-2.0 meters higher than the upper edge of the existing underground structure M, so that the bottom plate is used for horizontal seepage prevention, and the seepage prevention length of the structural foundation is increased. One end of the bottom plate 6, which is positioned on the upstream surface of the embankment, is connected with a cover 7, and the two are arranged at equal heights. The bottom plate 6 is connected with the flood control wall 5, the abutment 2 and the paving cover 7 by water stop (usually a rubber water stop belt 8), so that a horizontal seepage prevention structure is formed.
The vertical barrier structure, which cooperates with the horizontal barrier structure described above, is primarily borne by the barrier wall 9.
