Description
Technical Field
The invention relates to the technical field of hydraulic engineering, in particular to a dike structure spanning existing underground structures.
Background
The embankment project refers to water retaining buildings built along the edges of rivers, channels, lakes, seacoasts or flood areas, flood diversion areas and reclamation areas. With the continuous emergence of extreme weather, China pays more and more attention to the construction of a flood control system, and the effect of the embankment project is more prominent. However, in a river with a wide river beach, a newly-built embankment often intersects with existing underground structures such as inverted siphons, water pipelines, natural gas pipelines and the like, and at the time, the embankment filling causes that the stress and foundation settlement of the existing underground structure in a pressing range are overlarge, so that the safety and normal operation of the existing underground structure are affected. In order to solve the problems, the existing underground structures in the pressing range are mostly dismantled and rebuilt, namely in-situ structures in the influence range of the embankment are dismantled, the in-situ structures are designed again after the embankment is covered, necessary basic treatment measures are set, and structural parameters are increased to meet the requirements of the covered embankment. Since the demolition and reconstruction of the in-situ structure must be performed in its outage state, it is difficult to determine its outage period in the embankment construction period, and this uncertainty factor has a serious influence on the implementation of the embankment project.

The abutment is a gravity abutment which is horizontally arranged at an interval of 4.5-5.5 meters with the existing underground structure and is used for reducing the influence of construction on the existing underground structure.
The flood control wall is of a hollow 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 pier abutments, 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 plays a role in supporting and controlling flood.
The weight of the bottom plate is equivalent to the weight of the original soil covering above the existing underground structure, and the bottom of the bottom plate is 1.0-2.0 meters higher than the upper edge of the existing underground structure, so that the bottom plate is used for seepage prevention in the horizontal direction and the seepage prevention length of the structure foundation is increased.
The bottom plate is connected with the flood control wall, the pier and the paving cover by water stopping, so that a horizontal seepage-proofing structure is formed.
The impervious wall comprises the cement mixing pile that sets up in succession and cup joint each other, and impervious wall and shop cover mutually perpendicular, and the junction of impervious wall and shop cover adopts soil cement or clay outsourcing to form perpendicular seepage prevention structure, its and above-mentioned horizontal seepage prevention structure combined action can effectively prevent flood control wall both sides side direction and around oozing.
The embankment structure spanning the existing underground structure can be constructed under the condition that the existing underground structure keeps normal operation, 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 the crossing of a newly-built embankment and the existing underground structure is solved; secondly, the embankment structure of the invention does not affect the safety of the existing underground structure, ensures the functional continuity of the embankment, and has flood control and upper traffic functions.

Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific construction processes are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 to 4, the dike structure spanning an existing underground structure according to the present invention includes a dike 1 of a two-stage structure disposed above an existing underground structure M, and axes of the dike 1 and the existing underground structure M are arranged to intersect with each other, and in this embodiment, the axis of the dike 1 is perpendicular to the axis of the existing underground structure M.
The abutments 2 are arranged at the end of each section of the dike 1, the bottom of each abutment 2 is provided with a group pile 3, and a bridge 4 positioned above the existing underground structure M is arranged between the abutments 2. In general, the abutments 3 are gravity type abutments which are horizontally spaced from the existing underground structure M by 4.5 to 5.5 meters for reducing the influence of construction on the existing underground structure M. The bridge 4 is 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 dike 1 is arranged between the abutments 2, the flood control wall 5 is positioned on the upstream side of the dike 1, a hollow box type structure is made of reinforced concrete doped with high-performance polypropylene fibers, the two sides of the hollow box type structure are rigidly connected with the abutments 2, pouring is carried out at the same time, and the bottom of the hollow box type structure is connected with the bottom plate 6 in a water-stop manner.
The bottom plate 6 is arranged at the bottom of the flood control wall 5, one end of the bottom plate extends towards the upstream side of the dike 1, and the other end of the bottom plate extends towards the downstream side of the dike 1, so that the seepage-proofing arrangement requirement of the SL265-2016 sluice design specification 4.3.2 can be met. Furthermore, the weight of the bottom plate 6 is equivalent to the weight of the original soil covering above the existing underground structure M, and the bottom of the bottom plate is 1.0-2.0 meters higher than the upper edge of the existing underground structure, so that the bottom plate is used for seepage prevention in the horizontal direction and the seepage prevention length of the structure foundation is increased. One end of the bottom plate 6, which is positioned on the upstream surface of the dike, is connected with a paving cover 7, and the two are arranged at the same height. The bottom plate 6 is connected with the flood control wall 5, the abutment 2 and the paving cover 7 by water stopping (usually rubber water stopping belts 8) to form a horizontal seepage-proofing structure.
The vertical seepage-proofing structure co-acting with the horizontal seepage-proofing structure is mainly borne by the seepage-proofing wall 9. The impervious wall 9 is two sections, set up in both sides of existing underground structure M separately, each section is along the edge of the blanket 7 and turn to the L-shaped structure that extends along its axial direction under the dyke 1, it is formed by cement mixing pile that sets up in succession and cup joints each other, the impervious wall 9 is mutually perpendicular with the blanket 7, and the junction of the impervious wall 9 and the blanket 7 adopts soil cement or clay outsourcing, when it works with the above-mentioned horizontal impervious structure together, can prevent the lateral seepage by-pass of the both sides of the flood wall effectively.
During construction, firstly piling according to a designed position to form a pile group 3 and an impervious wall 9, then laying a bottom plate 6 and a paving cover 7, constructing a pier 2 and a flood control wall 5, forming a water-stopping structure on the connecting surface of the bottom plate 6, the flood control wall 5, the pier 2 and the paving cover 7 according to a rubber water-stopping belt 8, and finally building a dike 1.
