Description

Technical Field

[0001] The invention relates to the technical field of ice bridges, in particular to an ice bridge for transporting goods across rivers in cold regions and a construction method thereof. Background Art

[0002] In cold regions, the naturally frozen ice on the surface of rivers in winter is often used for light transportation, especially in the fields of island protection projects in the middle of the river or material transportation on both sides of the river. It is usually used for light-load transportation of machinery, equipment, materials, etc. However, the existing ice bridge construction methods mainly rely on the ice formed by the natural freezing of rivers in winter, which usually only meets the needs of people passing, small cars, ice transportation and light machinery. Since these naturally frozen ice layers are thin, the strength and stability are limited, they can only support low-load vehicles, such as small cars or light equipment, and cannot provide sufficient support for heavy machinery, large materials and heavy-load transportation. The ice bridge structure in the prior art does not take into account the actual needs of heavy-load transportation, and lacks effective reinforcement measures and support structures, resulting in greater safety hazards in actual applications. Especially when transporting heavier materials, the ice surface is prone to cracking and settling, causing the bridge deck to fail and increase transportation risks. In addition, existing ice bridge structures mostly rely on naturally frozen ice. When the temperature fluctuates greatly in cold regions, the strength and stability of the ice layer cannot be guaranteed in the long term, which results in the bridge deck's bearing capacity being affected by environmental changes, making it difficult to continue to meet the needs of heavy-load transportation.

[0003] Therefore, a solution is proposed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an ice bridge for transporting goods across rivers in cold regions and a construction method, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an ice bridge for transporting goods across rivers in cold regions, the ice bridge comprising: bank slope, used to connect the ice bridge to the river bank; Pine poles placed perpendicular to the water flow direction are used to strengthen the ice bridge structure; Pine poles parallel to the water flow are placed parallel to the water flow and alternate with pine poles perpendicular to the water flow to form the reinforced skeleton of the ice bridge; The natural ice surface serves as the foundation of the ice bridge and carries the transport load.

[0006] Preferably, the design width of the ice bridge is 6-8m, and the snow-clearing width of the ice surface at the ice track is 20-25m.

[0007] Preferably, it also includes snow banks, which are formed by cleared snow and are located on both sides of the ice bridge to enhance the stability of the ice bridge.

[0008] Preferably, the pine wood poles perpendicular to the water flow direction and the pine wood poles parallel to the water flow direction are tied and fixed by using double-strand iron wires, and the tying points are the intersection points of the upper and lower wood poles.

[0009] Preferably, the pine poles in the direction perpendicular to the water flow and the pine poles in the direction parallel to the water flow are placed in an alternating manner, wherein the pine poles in the direction perpendicular to the water flow are perpendicular to the water flow direction, and the pine poles in the direction parallel to the water flow are parallel to the water flow direction, and the alternating arrangement spacing of the two layers of poles is 50-60cm, forming a solid reinforced skeleton.

[0010] Preferably, a plastic film is provided on the inner side of the snow bank to serve as a template on both sides of the ice bridge construction, and the plastic film is used to prevent water from seeping out when pouring the ice layer.

[0011] Preferably, the ice track thickness of the ice bridge is not less than 100 cm, and when the thickness of the natural ice layer is less than 50 cm, a 50-60 cm thick ice layer is poured first, and then subsequent ice bridge construction is carried out to ensure that the ice surface reaches sufficient bearing capacity.

[0012] A construction method for transporting goods across rivers in cold regions comprises the following steps: S1. Clearing ice and building snowbanks Before construction, first clear the snow on the river or ice surface to ensure that the ice surface is clean and free of debris, and then pile the cleared snow on both sides of the ice bridge to form a snow bank. The height and width of the snow bank are adjusted according to the design requirements of the ice bridge to enhance the stability of the ice bridge and prevent water seepage; S2. Laying plastic film Lay an impermeable plastic film on the inner side of the snow bank, where the plastic film can cover both sides of the entire ice bridge; S3. Measure and evaluate the thickness of natural ice Before starting construction, measure the thickness of the natural ice layer. If the thickness of the natural ice layer is less than 50cm, first pour a 50cm thick ice layer to ensure that the basic ice layer can support subsequent construction work; S4. Pouring the first layer of ice After measuring and processing the thickness of the natural ice layer, pour the first layer of 50cm thick ice layer, where this layer of ice needs to be evenly distributed to ensure that the ice surface is flat and solid as the basic bearing layer; S5, Tie up wooden poles and reinforce the skeleton After the first layer of ice solidifies, pine poles perpendicular to the water flow and pine poles parallel to the water flow are arranged alternately to form a reinforced skeleton, and double-strand iron wires are used to tie the intersections of the upper and lower poles. S6. Pouring the second layer of ice After the binding of the wooden pole reinforcement frame is completed, the second layer of ice with a thickness of 50cm will be poured. This layer of ice will cover the wooden pole frame and merge with the first layer of ice to form an integral structure. S7. Strengthen the ice bridge structure After the second layer of ice solidifies, local reinforcement is carried out as needed. If the bearing capacity of the ice bridge is insufficient, the ice thickness is increased and the binding structure of the wooden poles is appropriately adjusted according to the on-site conditions to ensure that the ice bridge can meet the heavy-load transportation needs; S8. Check the overall stability of the ice bridge After the construction of the ice bridge is completed, an overall inspection is carried out to check whether the various structures of the ice bridge are stable, whether the ice layer is uniform, and whether the wooden pole reinforced frame is firm, to ensure that the ice bridge can safely carry the expected heavy traffic.

[0013] The present invention provides an ice bridge for transporting goods across rivers in cold regions and a construction method thereof. The invention has the following beneficial effects: 1. The present invention can greatly improve the bearing capacity and stability of the ice bridge through reasonable construction methods, such as multi-layer ice reinforcement and wooden pole skeleton support. The base layer of the ice bridge adopts a 50 cm thick base ice layer, and the second layer of reinforced ice layer further increases the strength, thereby enhancing the bearing capacity of the ice surface and supporting heavier vehicles and mechanical equipment. In particular, through the vertical and horizontal reinforcement design of the wooden poles, the ice bridge has stronger compression and bending resistance, which can effectively prevent the ice surface from breaking or settling when transporting heavy objects, thereby greatly reducing the risks during transportation. In addition, the structural design of the ice bridge can adapt to extreme temperature differences in cold areas. Due to the combination of the wooden pole skeleton and the ice layer, the stress on the ice surface caused by temperature fluctuations can be effectively alleviated, ensuring that the bridge deck can maintain transportation stability for a long time in unstable climates. This improvement in strength and stability ensures the safety of cross-river transportation in winter and avoids dangerous accidents on the ice surface under heavy loads.

[0014] 2. The present invention greatly saves construction costs and time by utilizing natural ice resources in cold regions and using simple construction methods. By simplifying the construction process, a solid transportation channel can be quickly constructed by simply cleaning the ice surface, reinforcing the wooden pole skeleton, and pouring the ice layer. This process avoids the reliance on heavy machinery and large-scale materials in traditional construction methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Please refer to the attached Figure 1 - Attachment Figure 3 , an embodiment of the present invention provides an ice bridge for transporting goods across rivers in cold regions, the ice bridge comprising: Bank slope 1, used to connect the ice bridge and the river bank; Specifically, the bank slope 1 is located on both sides of the ice bridge and is used to connect the ice bridge to the river bank. Its main function is to provide support and a stable foundation for the ice bridge, ensure that the ice bridge and the shore can be smoothly connected, and avoid displacement of the ice bridge due to temperature changes, melting of the ice layer or deformation of the ice surface. The design of the bank slope 1 allows the ice bridge to be smoothly connected with the transportation route on the shore to form a continuous transportation channel.

[0019] Pine wood poles 2, placed perpendicular to the water flow direction, are used to strengthen the ice bridge structure; Specifically, the pine poles 2 perpendicular to the water flow are wooden poles placed perpendicular to the water flow direction of the river, and are mainly used to enhance the structural stability and load-bearing capacity of the ice bridge. Since the impact force of the water flow and temperature changes may cause the ice layer to be unstable, the design of the pine poles perpendicular to the water flow direction can effectively disperse the impact of the water flow on the ice surface, and slow down the cracking and displacement of the ice layer. At the same time, these vertical wooden poles also play a reinforcing role, improving the compression resistance and bending resistance of the ice bridge during heavy-load transportation, and avoiding collapse or damage caused by excessive pressure on the ice surface.

[0020] Pine wood poles 3 parallel to the water flow direction are placed parallel to the water flow direction and are alternately matched with pine wood poles 2 perpendicular to the water flow direction to form a reinforced skeleton of the ice bridge; Specifically, the pine poles 3 parallel to the water flow direction and the pine poles 2 perpendicular to the water flow direction are alternately matched and arranged in parallel to the water flow direction to form a reinforced skeleton of the ice bridge. The layout of these poles parallel to the water flow direction effectively enhances the longitudinal and transverse strength of the ice bridge, allowing the ice surface to evenly distribute stress when subjected to the pressure from heavy-load transportation, avoiding local overload. The reinforcement structure of the staggered combination of pine poles 3 parallel to the water flow direction and pine poles 2 perpendicular to the water flow direction improves the overall stability of the ice bridge and enhances the ice layer's ability to support heavy-load transportation, thereby effectively preventing cracks in the ice layer from expanding or breaking.

[0021] The natural ice surface 4 serves as the foundation of the ice bridge and carries the transport load.

[0022] Specifically, the natural ice surface 4 is the base layer of the ice bridge, located at the bottom of the ice bridge, and carries the transport load. The ice surface is usually formed by the natural freezing of rivers in winter, but in the present invention, it is not the only load-bearing structure, but is combined with the basic ice layer to form a composite structure through the reinforcement measures supported by the above-mentioned wooden poles. The natural ice surface, as the base layer, can effectively provide initial load-bearing capacity, and through the reinforcement of wooden poles in vertical and horizontal directions, the ice surface can carry heavier transport loads, especially large machinery and heavy equipment. The thickness and strength of the ice surface need to be evaluated and adjusted according to actual use to ensure that it can remain stable under different climatic conditions and provide sufficient load-bearing capacity.

[0023] The design width of the ice bridge is 6-8m, and the snow-clearing width of the ice surface at the ice track is 20-25m.

[0024] The ice bridge also includes a snow bank 6, which is formed by cleared snow and is located on both sides of the ice bridge to enhance the stability of the ice bridge.

[0025] Specifically, the snow bank 6 is located on both sides of the ice bridge and is formed by the accumulation of cleared snow. The main function of the snow bank is to enhance the lateral stability and overall load-bearing capacity of the ice bridge. In cold regions, snow usually has good density and strength. Therefore, by clearing snow from the surrounding area and accumulating it into a bank, additional support can be provided to the ice bridge to prevent the ice surface from tilting, settling or breaking due to temperature fluctuations, external pressure or excessive transport load.

[0026] The pine wood poles 2 in the direction perpendicular to the water flow and the pine wood poles 3 in the direction parallel to the water flow are tied and fixed by double-strand iron wires, and the tying points are the intersection points of the upper and lower wood poles.

[0027] Specifically, the double-strand iron wire tying method can provide stronger tension and stability compared to the traditional single-strand tying method, and effectively prevent the poles from deflecting or falling off due to transportation loads or external forces. The double-strand iron wire can fix adjacent poles together more firmly, so that the poles perpendicular to and parallel to the water flow direction form a more solid and stable reinforced skeleton. The tying point is located at the intersection of the upper and lower wooden poles. This design can maximize the stability of each wooden pole and avoid the structural weaknesses caused by single-point tying.

[0028] The pine poles 2 perpendicular to the water flow direction and the pine poles 3 parallel to the water flow direction are placed in an alternating manner, wherein the pine poles 2 perpendicular to the water flow direction are perpendicular to the water flow direction, and the pine poles 3 parallel to the water flow direction are parallel to the water flow direction, and the alternating arrangement spacing of the two layers of poles is 50-60cm, forming a solid reinforced skeleton.

[0029] Specifically, the alternating arrangement spacing of the pine poles 2 in the direction perpendicular to the water flow and the pine poles 3 in the direction parallel to the water flow is 50-60 cm. This design not only ensures that the spacing between the poles is reasonable, avoiding insufficient load-bearing capacity due to too sparse structure, but also effectively improves the support of the ice surface. Reasonable spacing design enables the poles to better distribute pressure, enhance the support of the ice surface for heavy-load traffic, and provide sufficient space to cope with the expansion or contraction of the ice surface due to temperature fluctuations. Through this staggered arrangement, a more stable and solid mesh skeleton structure can be formed between the poles, maximizing the strength of the ice bridge, ensuring that the ice bridge can still maintain long-term stability under extreme climatic conditions, and supporting the needs of heavy-load transportation.

[0030] A plastic film 5 is arranged inside the snow bank 6 to serve as a template on both sides of the ice bridge construction. The plastic film 5 is used to prevent water from seeping out when pouring the ice layer.

[0031] The thickness of the ice track of the ice bridge is not less than 100cm. When the thickness of the natural ice layer is less than 50cm, a 50-60cm thick ice layer is poured first, and then subsequent ice bridge construction is carried out to ensure that the ice surface has sufficient bearing capacity.

[0032] A construction method for transporting goods across rivers in cold regions comprises the following steps: S1. Clearing ice and building snowbanks Before construction, first clear the snow on the river surface or ice surface to ensure that the ice surface is clean and free of debris, and pile the cleared snow on both sides of the ice bridge to form a snow bank 6, wherein the height and width of the snow bank 6 are adjusted according to the design requirements of the ice bridge to enhance the stability of the ice bridge and prevent water from seeping out; S2. Laying plastic film An impermeable plastic film 5 is laid on the inner side of the snow bank 6, wherein the plastic film 5 can cover both sides of the entire ice bridge; S3. Measure and evaluate the thickness of natural ice Before starting construction, measure the thickness of the natural ice layer. If the thickness of the natural ice layer is less than 50cm, first pour a 50cm thick ice layer to ensure that the basic ice layer can support subsequent construction work; S4. Pouring the first layer of ice After measuring and processing the thickness of the natural ice layer, pour the first layer of 50 cm thick natural ice surface 4, wherein this layer of ice surface needs to be evenly distributed to ensure that the ice surface is flat and solid as the basic bearing layer; S5, Tie up wooden poles and reinforce the skeleton After the first layer of ice solidifies, pinewood poles 2 perpendicular to the water flow direction and pinewood poles 3 parallel to the water flow direction are arranged alternately to form a reinforced skeleton, and double-strand iron wires are used to tie the intersections of the upper and lower wood poles; S6. Pouring the second layer of ice After the binding of the wooden pole reinforcement frame is completed, the second layer of natural ice surface 4 is poured, with a thickness of 50 cm. This layer of ice will cover the wooden pole frame and merge with the first layer of ice to form an integral structure; S7. Strengthen the ice bridge structure After the second layer of ice solidifies, local reinforcement is carried out as needed. If the bearing capacity of the ice bridge is insufficient, the ice thickness is increased and the binding structure of the wooden poles is appropriately adjusted according to the on-site conditions to ensure that the ice bridge can meet the heavy-load transportation needs; S8. Check the overall stability of the ice bridge After the construction of the ice bridge is completed, an overall inspection is carried out to check whether the various structures of the ice bridge are stable, whether the ice layer is uniform, and whether the wooden pole reinforced frame is firm, to ensure that the ice bridge can safely carry the expected heavy traffic.
