[0026] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0027] It should be noted that many specific details are set forth in the following description to facilitate a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific implementation manners disclosed below.
[0028] The lakeside greenway is a pedestrian or non - motor vehicle passage built around the lake. Usually, the road width is 3m to 6m. The main function of the lakeside greenway is to serve as an ecological barrier around the lake, to demarcate the boundary and avoid encroaching on the existing water body. At the same time, it also plays a role in ecological environment patrol, monitoring and tourism sightseeing.
[0029] In the related art, as a linear ribbon project, the natural environment along the lakeside greenway is diverse. For the mountain greenway, in most areas, the current roads are relatively narrow and need to be widened. Common road widening methods include retaining wall filling and widening. Retaining wall filling and widening means setting a retaining wall on the outside of the road and filling the roadbed inside the retaining wall.
[0030] However, for the lakeside greenway, usually the mountain is relatively steep and the outside of the road is adjacent to the water surface. Using the method of retaining wall filling and widening will not only encroach on the water body, but also, since retaining wall filling and widening requires building cofferdams and excavating foundation pits in the water during the construction of the retaining wall, the construction is difficult and the water quality is affected.
[0031] Therefore, the embodiment of the present application provides a widened structure for a lakeside greenway to solve the technical problems in the related art that when widening the lakeside greenway, the method of using a retaining wall to fill soil not only occupies the water body but also affects the water quality.
[0032] Figure 1 FIG. 4 is a side view of a widened structure for a lakeside greenway provided by an embodiment of the present application; Figure 2 FIG. 5 is a top view of a widened structure for a lakeside greenway provided by an embodiment of the present application.
[0033] Referring to Figure 1 and Figure 2 The embodiment of the present application provides a widened structure for a lakeside greenway, including a support assembly 100, a precast slab 200, and a concrete assembly 300;
[0034] The support assembly 100 includes a ground beam 110 and a reinforcement member 120. The ground beam 110 extends along the road widening direction; at least two reinforcement members 120 are arranged along the road widening direction. One end of the reinforcement member 120 is fixed to the foundation, and the other end of the reinforcement member 120 is fixed to the ground beam 110;
[0035] The precast slab 200 and the concrete assembly 300 are both laid side by side along the road widening direction on the side of the ground beam 110 facing away from the reinforcement member 120. Among them, at least one reinforcement member 120 is provided at the bottom of each of the precast slab 200 and the concrete assembly 300, and the precast slab 200 is arranged on the water-facing side to facilitate the filling of the concrete assembly 300 with vehicle loads.
[0036] It should be noted that in the embodiment of the present application, the lakeside greenway is arranged in the mountain and built around the lake.
[0037] It should be further noted that the water-facing side described in the embodiment of the present application is the side close to the lake 600, and the widened structure in the present application is not arranged on the Figure 1 and Figure 2 ground 700 shown in
[0038] Exemplarily, the ground beam 110 can be a reinforced concrete ground beam 110 or a prestressed concrete ground beam 110. Among them, the reinforced concrete ground beam 110 is composed of concrete, steel bars, plates, etc. Its longitudinal steel bars and transverse steel bars can well bear the load and ensure the bending bearing capacity of the ground beam 110. The prestressed concrete ground beam 110 is to add prestressed steel bars to the concrete. Through the prestress action, the steel bars are in a prestressed state, which can effectively resist the load and improve the bearing capacity of the ground beam 110.
[0039] Exemplarily, the reinforcement member 120 may adopt micropiles 121. There are at least two micropiles 121 arranged along the road widening direction. Among them, one micropile 121 is arranged at the bottom of the precast slab 200, and the other micropile 121 is arranged at the bottom of the concrete component 300 to respectively support and reinforce the precast slab 200 and the concrete component 300.
[0040] It should be further noted that the precast slab 200 is a precast concrete member produced and processed in a precast yard and can be directly transported to the construction site for precasting.
[0041] The embodiment of the present application provides a structure for widening a lakeside greenway. In the embodiment of the present application, through the arrangement of the reinforcement member 120 and by evenly arranging at least two reinforcement members 120 along the road widening direction, the ground beam 110 can be supported, avoiding the overturning of the ground beam 110 caused by eccentric loading driving and improving the stability of the ground beam 110. In the embodiment of the present application, by arranging the precast slab 200 on the water-facing side, the setting of the retaining wall is omitted, avoiding the occupation of water bodies and playing a certain role in protecting the ecological environment. Further, through the arrangement of the precast slab 200, during the construction process, the precast slab 200 is precast and then transported to the site for installation. After the installation of the precast slab 200 is completed, vehicles can drive on the road where the precast slab 200 is laid for the filling of the concrete component 300, facilitating the construction of the lakeside road and reducing the construction difficulty. Through the arrangement of the embodiment of the present application, a structure for widening a lakeside greenway that protects the ecological environment and reduces the construction difficulty is provided.
[0042] In some examples, the reinforcement member 120 includes micropiles 121 and uplift anchor rods 122. The micropiles 121 are arranged below the precast slab 200, and the uplift anchor rods 122 are arranged below the concrete component 300.
[0043] For example, the micropiles 121 can be cast-in-place piles using construction techniques such as drilling, strong reinforcement, and pressure grouting.
[0044] Again, for example, the uplift anchor rods 122 are fixed to the foundation by drilling holes in the ground and grouting or using materials such as prestressed steel bars, thereby preventing the settlement of the foundation. The uplift anchor rods 122 can enhance the bearing capacity of the anchor rods through the span and load-bearing area between the rods, thereby achieving the purpose of uplift resistance.
[0045] Through the arrangement of the micropiles 121 and uplift anchor rods 122 in the embodiment of the present application, the micropiles 121 can bear the vehicle load on the precast slab 200, and the micropiles 121 and uplift anchor rods 122 form a frame system, which can effectively avoid the overturning of the ground beam 110 caused by eccentric loading driving of vehicles.
[0046] Exemplarily, the reinforcement member 120 further includes an enlarged foundation 123;
[0047] The enlarged foundation 123 is filled at the bottom of the ground beam 110, and the uplift anchor rod 122 extends into the ground beam 110 through the enlarged foundation 123.
[0048] During specific implementation, the enlarged foundation 123 is reserved with anchor reinforcement extending into the ground beam 110. After being filled and consolidated together with the ground beam 110, an integral stress-bearing member is formed to transfer the loads of people and vehicles on the widened road.
[0049] In the embodiment of the present application, through the cooperation of the enlarged foundation 123 and the uplift anchor rod 122, better support can be provided for the ground beam 110. Further, through the arrangement of the enlarged foundation 123, the uplift anchor rod 122 and the micropiles 121, a support framework can be formed for the ground beam 110 to improve the stability of the ground beam 110.
[0050] Exemplarily, the concrete component 300 is filled with plain concrete.
[0051] It should be noted that plain concrete is a structure made of concrete without steel bars or without arranged stress-bearing steel bars. Among them, the concrete component 300 can adopt C25 plain concrete.
[0052] In the embodiment of the present application, by filling the concrete component 300 with plain concrete, since plain concrete has strong impermeability, it can play a protective role for the ground beam 110 and the like. Further, plain concrete also has strong compressive capacity and can improve the strength of the widened structure of the lakeside greenway.
[0053] Exemplarily, the widened structure of the lakeside greenway further includes a waterproof component 400, and the waterproof component 400 is filled on the side of the precast slab 200 and the concrete component 300 facing away from the ground beam 110.
[0054] In the embodiment of the present application, through the arrangement of the waterproof component 400, it can prevent rainwater from scouring and eroding the precast slab 200, the concrete component 300 and the ground beam 110, etc., and thus can play a protective role for the precast slab 200 and the concrete component 300.
[0055] For example, the waterproof component 400 at least includes a waterproof layer 420, and the waterproof layer 420 is set as a waterproof film.
[0056] In some other examples, the waterproof layer 420 can also be a waterproof coating, for example, an asphalt coating. Of course, during specific implementation, other materials can also be used to set the waterproof layer 420, which is not specifically limited herein.
[0057] For another example, the waterproof component 400 further includes a plain concrete layer 430 and an asphalt concrete layer 410. Among them, the plain concrete layer 430 is filled on the side of the precast slab 200 and the concrete component 300 facing away from the ground beam 110, and the asphalt concrete layer 410 is filled above the waterproof layer 420.
[0058] It should be noted that the plain concrete layer 430 can adopt C40 cast-in-place concrete, and the filling thickness is 80 mm. The filling thickness of the asphalt concrete layer 410 can be 90 mm.
[0059] In the embodiment of the present application, through the arrangement of the plain concrete layer 430 and the asphalt concrete layer 410, the strength of the lakeside waterproof structure can be further improved.
[0060] In some other examples, the ground beam 110 is provided with a limiting portion 111, and the limiting portion 111 is provided as a protrusion of the ground beam 110 on the water-facing side facing away from the reinforcement member 120.
[0061] In the embodiment of the present application, by arranging the limiting portion 111 on the ground beam 110, on the one hand, the precast slab 200 can be limited to prevent the precast slab 200 from slipping; on the other hand, it facilitates the positioning and installation of the precast slab 200.
[0062] In some examples, the widening structure further includes a guardrail 500, and the guardrail 500 is arranged on the water-facing side of the precast slab 200.
[0063] In the embodiment of the present application, through the arrangement of the guardrail 500, it can prevent pedestrians or vehicles from falling into the water, and can play a good protective role for pedestrians and vehicles on the road.
[0064] In specific implementation, the length of the ground beam 110 is set to 4800 mm, the width is set to 1000 mm, the height is set to 600 mm, and the height of the limiting portion 111 can be set to 300 mm.
[0065] The micropile 121 is set as a cylinder with a diameter of 300 mm. The height from the bottom of the micropile 121 to the ground beam 110 is 1200 mm, and the distance from the center of the micropile 121 to the water-facing side of the ground beam 110 is 1500 mm. The anchoring force of the anti-pull anchor 122 is greater than or equal to 200 kN.
[0066] The length of the enlarged foundation 123 is set to 1000 mm, the width is set to 1500 mm. The enlarged foundation 123 is coaxially arranged along its width direction and the width direction of the ground beam 110. The micropile 121 protrudes 250 mm from the ground beam 110 along the length direction on the side facing away from the water.
[0067] The thickness of the precast slab 200 is 400 mm, and two precast slabs 200 can be arranged along the width direction of the widening structure.
[0068] It is easily understandable that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.
[0069] The above specific implementation manners further elaborate in detail the objectives, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only the specific implementation manners of the embodiments of the present application, and are not used to limit the protection scope of the embodiments of the present application.
