Description

Technical Field

[0001] The present invention relates to the technical field of embankments and municipal roads, and more specifically to a embankment-road integrated structure for arranging municipal facilities. The present invention also relates to a construction method of the embankment-road integrated structure for arranging municipal facilities. Background Art

[0002] Levee projects generally refer to water-retaining structures built along rivers, canals, lakes, coasts, or at the edges of floodways, flood diversion areas, and reclaimed areas. Urban roads generally refer to roads used for transportation and pedestrians within a city, facilitating residents' daily lives, work, and recreational activities, and connecting with roads outside the city to facilitate external traffic. Traditional levees primarily functioned as flood control and water retention, with the roads atop them serving only as inspection routes during flood season, rarely considering the transportation needs of surrounding cities. However, with the continuous development of cities and advancements in water conservancy infrastructure, the integration of water, cities, and landscapes is becoming a growing trend, and levee roads are gradually taking on some of the city's transportation functions.

[0003] In this context, the embankment-road integration project has become a product of green ecological urban development. It not only has the water-retaining function of the embankment, but can also serve as the main or secondary urban road, facilitating traffic, transportation or pedestrian use for connecting the city inside and outside. Currently, the embankment-road integration project often simply widens the road on top of the embankment.

[0004] In addition to the basic function of accommodating motor vehicles, non-motor vehicles and pedestrians, urban roads often undertake the layout of municipal engineering projects, including street lights, green trees, cable trenches, communication lines, sewage pipes, etc.; according to the "Design Code for Embankment Engineering" (GB50286-2013), trees should not be planted on the embankment, and the structures or facilities inside the embankment must also be ensured not to affect the operation and safety of the embankment.

[0005] Therefore, how to reasonably and legally consider the layout of municipal facilities in the embankment-road integration project is an urgent problem that needs to be solved. Summary of the Invention

[0006] The first purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a levee-road integrated structure for setting up municipal facilities.

[0007] The second object of the present invention is to provide a construction method for this embankment-road integrated structure for setting up municipal facilities.

[0008] To achieve the first objective, the present invention provides a technical solution comprising: a levee-road integrated structure for arranging municipal facilities, characterized in that: the levee comprises a main levee fill area adjacent to the outer river waters and a secondary levee fill area adjacent to the outer river waters; the main levee fill area has a waterfront slope protection on the side adjacent to the outer river waters, and the secondary levee fill area has a waterfront slope protection on the side adjacent to the outer river waters;

[0009] On the upper part of the main sub - area and the secondary sub - area of the embankment fill, a sidewalk, a non - motor vehicle lane, and a motor vehicle lane are successively arranged from outside to inside;

[0010] There is a cable trench under the sidewalk of the secondary sub - area of the embankment fill;

[0011] There is a communication pipe group between the back - water slope protection and the cable trench;

[0012] There is a sewage pipe under the ground outside the back - water slope protection.

[0013] In the above - mentioned technical solution, the cross - section of the main sub - area of the embankment fill is trapezoidal, and the cross - section of the secondary sub - area of the embankment fill is parallelogram - shaped.

[0014] In the above - mentioned technical solution, there are street lamps between the sidewalk and the non - motor vehicle lane on the main sub - area of the embankment fill.

[0015] In the above - mentioned technical solution, there are street lamps between the motor vehicle lane and the non - motor vehicle lane on the main sub - area of the embankment fill.

[0016] In the above - mentioned technical solution, there are street lamps between the non - motor vehicle lane and the motor vehicle lane on the secondary sub - area of the embankment fill.

[0017] In the above - mentioned technical solution, there are greening trees between the non - motor vehicle lane and the street lamps on the secondary sub - area of the embankment fill.

[0018] In the above - mentioned technical solution, the sidewalk, the non - motor vehicle lane, and the motor vehicle lane slope to both sides, and the slope is not less than 2%.

[0019] In order to achieve the above - mentioned second object, the technical solution of the present invention is: a construction method of an embankment - road integrated structure provided with municipal facilities, which is characterized by including the following steps:

[0020] Step 1: Implement the main sub - area and the secondary sub - area of the embankment fill;

[0021] Step 2: After filling to the embankment top, excavate the soil to the corresponding foundation elevation at the cable trench position and the communication pipe group position, then implement the cable trench and the communication pipe group. After completion, cover the upper part with soil to the embankment top;

[0022] Step 3: Implement the motor vehicle lane, the non - motor vehicle lane, the sidewalk, the greening trees, and the street lamps; Since the sewage pipe is located under the ground outside the back - water slope protection, after the embankment part is implemented, excavate and implement the sewage pipe.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1) The present invention combines municipal roads with flood control dikes. The top road of the dike is provided with motor lanes, non-motor lanes, sidewalks, etc., saving construction land and conforming to the trend of green development and ecological construction;

[0025] 2) The present invention proposes a double-zone structure for the embankment filling. The main zone of the embankment filling serves as the basic dike function guarantee area to avoid burying municipal facilities; the secondary zone of the embankment filling serves as a supplementary area, where municipal facilities can be expandably set without affecting the dike's water-blocking safety, meeting the requirements of relevant laws and regulations.

[0026] 3) The present invention supplements rich municipal functions to the integrated dike and road project, providing a dike and road structure for reasonably arranging facilities such as greening trees, street lamps, cable trenches, communication pipe groups, sewage pipes, etc. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will describe the implementation of the present invention in detail with reference to the drawings, but they do not constitute a limitation to the present invention and are only for illustration. At the same time, the advantages of the present invention will become clearer and easier to understand through the description.

[0033] Referring to the drawings, it can be seen that: a combined dike and road structure with municipal facilities is characterized in that it includes an embankment body 1; the embankment body 1 includes a main zone of the embankment filling 11 close to the outer river water area 2 and a secondary zone of the embankment filling 12 far from the outer river water area 2; on the side of the main zone of the embankment filling 11 close to the outer river water area 2, there is a water-facing slope protection 111, and on the side of the secondary zone of the embankment filling 12 far from the outer river water area 2, there is a backwater slope protection 121;

[0034] Above the main sub - area 11 and the secondary sub - area 12 of the embankment fill, there are a sidewalk 31, a non - motorized lane 32 and a motorized lane 33 arranged in sequence from outside to inside; specifically, above the main sub - area 11 of the embankment fill, there are a sidewalk 31, a non - motorized lane 32 and a motorized lane 33 arranged in sequence from the side close to the outer river water area 2 to the side far from the outer river water area 2; above the secondary sub - area 12 of the embankment fill, there are a sidewalk 31, a non - motorized lane 32 and a motorized lane 33 arranged in sequence from the side far from the outer river water area 2 to the side close to the outer river water area 2.

[0035] There is a cable trench 122 under the sidewalk 31 of the secondary sub - area 12 of the embankment fill.

[0036] There is a communication pipe group 123 between the back - water slope protection 121 and the cable trench 122.

[0037] There is a sewage pipe 5 under the ground outside the back - water slope protection 121.

[0038] The cross - section of the main sub - area 11 of the embankment fill is trapezoidal, and the cross - section of the secondary sub - area 12 of the embankment fill is parallelogram - shaped.

[0039] As Figure 1 shown, there is a street lamp 41 between the sidewalk 31 and the non - motorized lane 32 on the main sub - area 11 of the embankment fill.

[0040] As Figure 2 shown, there is a street lamp 41 between the motorized lane 33 and the non - motorized lane 32 on the main sub - area 11 of the embankment fill.

[0041] There is a street lamp 41 between the non - motorized lane 32 and the motorized lane 33 on the secondary sub - area 12 of the embankment fill.

[0042] There are greening trees 42 between the non - motorized lane 32 and the street lamp 41 on the secondary sub - area 12 of the embankment fill.

[0043] The sidewalk 31, the non - motorized lane 32 and the motorized lane 33 slope to both sides, and the slope is not less than 2%.

[0044] In actual use, the water - facing slope protection 111 is a precast concrete, masonry or ecological grass - brick slope protection to prevent soil and water loss of the embankment caused by wave scouring of the outer river water area 2.

[0045] The cross - section of the main sub - area 11 of the embankment fill is trapezoidal, mainly bearing the function of flood prevention and water retention, and also bearing the function of the roadbed. This structure itself has stable and anti - seepage conditions.

[0046] The secondary sub - area 12 of the embankment fill, with a parallelogram - shaped cross - section, bears non - flood - prevention functions and only bears the function of the roadbed.

[0047] The backwater slope protection 121 is an ecological grass-planting brick slope protection or a turf slope protection, mainly for stabilizing the embankment body, preventing rainwater scouring, and taking into account the ecological landscape effect.

[0048] The sidewalk 31 is a paved brick or concrete pavement, located on both sides of the top surface of the embankment body 1.

[0049] The non-motor vehicle lane 32 is a concrete pavement, an asphalt concrete pavement or a permeable pavement, etc., located on both sides of the top surface of the embankment body 1, adjacent to the sidewalk. If the width of the top of the embankment body 1 is insufficient, the width of the non-motor vehicle lane 32 can be reduced.

[0050] The motor vehicle lane 33 is an asphalt concrete pavement or a concrete pavement, located in the middle of the top surface of the embankment body 1;

[0051] The street lamp 41 is a lighting lamp with a metal pole system as the main body.

[0052] The greening trees 42 should preferably be shrubs, and avoid using tree species with developed root systems to reduce the depth of the tree roots entering the soil.

[0053] The cable trench 122 is a hollow box culvert structure, made of concrete or brick masonry, buried under the sidewalk 31 of the embankment filling secondary sub-area 12, and does not exceed the scope of the embankment filling secondary sub-area 12;

[0054] The communication pipe group 123 is a pipe group composed of PVC pipes or fiberglass pipes, laying communication cables. The communication pipe group 123 is located between the backwater slope protection 121 and the cable trench 122, effectively avoiding additional land occupation.

[0055] The sewage pipe 5 is located below the ground outside the backwater slope protection 121, which is convenient for the self-flow discharge of urban sewage and also convenient for pipeline maintenance without disturbing the soil of the embankment body 1.

[0056] Such as Figure 3 and Figure 4 As shown, the sidewalk 31, the non-motor vehicle lane 32, and the motor vehicle lane 33 can be inclined to both sides at a certain slope, and the slope should not be less than 2% to facilitate the confluence of rainwater on the road surface and flow down along the slope.

[0057] A construction method for a combined embankment and road structure with municipal facilities set thereon includes the following steps: The overall construction sequence is from bottom to top;

[0058] Step 1: Implement the main embankment filling sub-area 11 and the secondary embankment filling sub-area 12. The main embankment filling sub-area 11 and the secondary embankment filling sub-area 12 are implemented synchronously, with the same height and the same compaction strength;

[0059] Step 2: After the soil filling reaches the embankment top, excavate the soil at the positions of the cable trench 122 and the communication pipe group 123 to the corresponding foundation elevation, then implement the cable trench 122 and the communication pipe group 123. After completion, cover the upper part with soil to the embankment top.

[0060] Step 3: Implement the motor vehicle lane 33, non-motor vehicle lane 32, sidewalk 31, greening trees 42 and street lights 41; since the sewage pipe 5 is located below the ground outside the backwater slope protection 121, after part of the embankment body 1 is implemented, excavate and implement the sewage pipe 5.
