Description
Method for forming a support system of a ski track
[0001] The present disclosure relates to the technical field of ski tracks, in particular to method for forming a support system of a ski track.
[0002] A ski track is a curved and extended concrete track with built-in cooling pipes to keep ice and snow layer on the surface in a stable state at low temperature. The track is mostly built in mountainous area, and winding extension of the track is formed by terrain. Athletes slide down from the mountain and use the terrain to realize actions such as diving and turning and sliding in corners. However, due to drop height between a natural terrain and the standard form of a track, it is generally necessary to set concrete columns under the track for support.
[0003] Existing reinforced concrete columns are anchored into the track floor below the track and the track concrete above through central columns, and the reinforced concrete columns are separated from the track floor and the track concrete by rubber bearings, so that the reinforced concrete columns are not in direct contact with the track concrete. Swinging columns of above-mentioned track columns are used in a snowmobile sied track.
Swinging columns have low anti-side-shift stiffness, and the track will be slightly displaced when subjected to upper load. This displacement can be self-regulated by elastic rubber which can also provide shock absorption.
[0004] However, the performance of rubber materials is greatly affected by temperature. When the temperature is between the glass transition temperature and the brittle temperature, the rubber is in the glass state, and the rubber molecules can only vibrate in situ, so that the deformation amount is extremely limited. When the temperature is between the glass transition temperature and the viscous flow temperature, the rubber is in the high elastic state and will have elastic deformation when subjected to external! force. When the external temperature rises to the viscous flow temperature, the rubber changes from the high elastic state to the viscous flow state. At this time, when the rubber is subjected to external force, irreversible plastic deformation will occur.
[0005] That is to say, in order to maintain the stable performance of the elastic rubber pad, it is necessary to maintain the ambient temperature not too high or too low. However, ski tracks are mostly built in the cold and temperate regions, where cold in winter and hot in summer will affect the properties of rubber. Moreover, once plastic deformation occurs, the rubber cannot be recovered, this will lead to high cost of track maintenance and overhaul, and reduced service life of the track.
[0006] In addition, during the use of the track, the track is easy to be subjected to repeated impacts. Moreover, the track is mostly built in the mountainous area, which is greatly affected by the wind load, so that support columns are prone to inclination after long-term use, resulting in the change of the inclination of upper track surface, affecting the normal use of the track and having safety hazard. Therefore, it is necessary to further improve the tightness between concrete support columns of the track, track main body and concrete base.
[0007] In view of the above analysis, the present disclosure provides a method for forming a support system of a ski track, so as to solve the problem of poor seismic performance of tracks in prior art.
[0008] The purpose of the present disclosure is mainly achieved by the following technical schemes:

[0014] Furthermore, in step 1, multiple track shear walls are disposed at equal intervals, and multiple track support columns are disposed between adjacent track shear walls.
[0015] Furthermore, a distance between adjacent track support columns is 2-5 meters; a distance between adjacent track shear walls is 30-50 meters, and multiple sets of track support columns are disposed between the adjacent track shear walls; distances between each of the track shear walls and adjacent track support columns are 2-3 meters. {0016] Furthermore, in step 2, when the base concrete of the track is poured, lower ends of the second central support columns and the first central support columns are poured integrally with the base concrete.
[0017] Furthermore, lower fixing plates are fixed at the lower ends of the second central support columns and the first central support columns; the tower fixing plates are perpendicular to the second central supporting columns and/or the first central supporting columns; after the lower fixing plates are adjust to be horizontal, the lower fixing plates are poured integrally with the base concrete.
[0018] Specifically, in step 2, when pouring the base concrete of the track, lower ends of the first central support columns and the second central support columns are poured integrally with the base concrete; lower fixing plates are fixed at the lower ends of the first central support columns and the second central support columns; the lower fixing plates are horizontally arranged; after the lower fixing plates are adjusted to be horizontal, the lower fixing plates are poured integrally with the base concrete. {0019] Furthermore, in step 3, each of the track shear walls comprises two second central support columns and a beam, wherein, second concrete columns are poured outside the second central support columns, and the beam connects two second concrete columns; the two second concrete columns and the beam of each of the track shear walls are poured integrally.
[0020] Furthermore, each of the track support columns comprises a first central support column and a first concrete column; the first concrete column is poured outside the first central support column; a rubber pad is arranged above the first concrete column, and the rubber pad is arranged between the track concrete and the first concrete column.
[0021] Furthermore, in step 4, a shear wall fixing plate is arranged above two second central support columns of each of the track shear walls.
[0022] Furthermore, two ends of the shear wall fixing plate are welded and fixed with two second central support columns; an upper fixing plate is welded at the upper end of the first central support column of each of the track support columns.
[0023] Furthermore, the shear wall fixing plate and the upper fixing plate are both poured integrally with the track concrete.
[0024] Furthermore, multiple tie bars are vertically arranged on each of the lower fixing plates; when pouring the base concrete, arranging the tie bars in the base concrete, welding the lower fixing plates above the tie bars, and welding the central support column on the lower fixing plates before the base concrete submerges the lower fixing plates; the tie bars are cylindrical support rods; or, the tie bars are corrugated struts; or, the tie bars are support rods with thorns.
[0025] Furthermore, the shear wall fixing plate and the upper fixing plate are all corrugated plates, and the ripple extension direction of the corrugated plates is consistent with the extension direction of the track concrete.
[0026] Furthermore, a protective cover and temperature control lamps are arranged outside the track support column; the protective cover is set outside the rubber pad, and the temperature control lamps are embedded into side walls of the protective cover .

[0029] 2. The method for forming a support system of a track adopts the track shear walls as the rigid support of the track main body (track concrete), and adopts the track support columns with the top provided with the rubber pads to flexibly support the track concrete; the track support system of the present disclosure realizes the support of the trace concrete by using the combination of the track shear walls and the track support columns, and this combination of rigid support and flexible support improves the impact resistance and overall stability of the track on the premise of ensuring the reliable support of the track concrete.

[0045] Embodiment 1
[0046] The present disclosure discloses a method for forming a support system of a ski track, including the following steps:
[0047] step 1: according to the shape of the track, arranging number and positions of track shear walls and track support columns;
[0048] step 2: pouring base concrete 4 of the track; at the same time, arranging second central support columns 14 for the track shear walls and first central support columns 3 for the track support columns in the base concrete 4;
[0049] step 3: pouring the track shear walls and the track support columns;
[0050] step 4: pouring track concrete 1 over the track shear walls and the track support columns.
[0051] The specific steps of step 1 are as follows:
[0052] In one embodiment of the present disclosure, in step 1, multiple track shear walls are disposed at equal intervals in a straight track segment of the track, and multiple track support columns are disposed between adjacent track shear walls, as shown in fig. 1.
[0053] In one embodiment of the present disclosure, a distance between adjacent track support columns is 2-5 meters; a distance between adjacent track shear walls is 30-50 meters, and multiple sets of track support columns are disposed between adjacent track shear walls; distances between each of the track shear walls and its adjacent track support columns are 2-3 meters.
[0054] Preferably, in the straight track segment of the track, the distance between two adjacent track shear walls is 35 meters; the distances between each of the track shear walls and its adjacent track support columns are 2.5 meters; the distance between two adjacent sets of track support columns is 2.5 meters. Further, 13 sets of track support columns are arranged between two track shear walls.
[0055] Furthermore, in a curve track segment of the track, the distance between the track shear walls is 20-40 meters. Specifically, when the track curve is in an S shape, track shear walls are provided at the start point, the center point, and the end point of the S-shaped curve. When the track curve is a circular arc, 2-4 track shear walls are uniformly distributed on the arc line of the circular arc track, and the number of the track shear walls is determined according to the length and the radian of the arc track.
[0056] The specific steps of step 2 are as follows:
[0057] Further, in step 2, when the base concrete 4 of the track is poured, lower ends of the first central support columns 3 and the second central support columns 14 are poured integrally with the base concrete 4; lower fixing plates 7 are fixed at the lower ends of the first central support columns 3 or the second central support columns 14; the lower fixing plates 7 are perpendicular to the first central supporting columns 3; and after the lower fixing plates 7 are adjusted to be horizontal, the lower fixing plates 7 are poured integrally with the base concrete 1.
[0058] Furthermore, multiple tie bars are vertically arranged on each of the lower fixing plates 7.
[0059] When pouring:
[0060] step 21: in the process of pouring the base concrete 4, arrange the tie bars in the base concrete 4 so as to be integrated with the base concrete 4,
[0061] Step 22: weld the lower fixing plates 7 above the tie bars, and continue to pour the base concrete 4.
[0062] Step 23: before the base concrete 4 submerges the lower fixing plates 7, weld the first central support columns 3 or the second central support columns 14 on the lower fixing plates 7.
[0063] Step 24: pour the base concrete 4 until the base concrete 4 submerges the lower fixing plates 7 as shown in fig. 2 and 3.
[0064] Further, the length of the tie bars is set as required, so that the tie bars and the lower fixing plates 7 are all arranged inside the base concrete 4. Alternatively, before the base concrete 4 is poured, the tie bars are driven into the foundation, namely the tie bars simuitaneously penetrate through the base concrete 4 and the ground below the base concrete 4; after the tie bars are fixed, the pouring of the base concrete 4 in step 21 is started, so that the tie bars and the base concrete 4 are integrated into one.
[0065] Specifically, the structural forms of the tie bars are shown in fig. 2, 3, 9 and 10.
[0066] As shown in fig. 2 and 3, the tie bars are cylindrical support rods 8; multiple support rods 8 are arranged perpendicular to each of the lower fixing plates 7 and are welded and fixed with the lower fixing plate 7, as shown in fig. 2 and 3. The bottom of each first central support columns 3 is set with one lower fixing plate 7 and multiple support rods 8, which can simulate tree roots, so that the first central support columns 3 (the second central support columns 14) and the first concrete columns 2 (the second concrete columns 15) are more closely combined with the base concrete 4, and are not liable to incline, so that to improve the wind resistance and seismic performance.
[0067] Alternatively, as shown in fig. 9, the tie bars are corrugated struts 8- 1; different from a corrugated plate, the corrugated struts 8-1 are of a corrugated rod-shaped structure, and their effect is the same as that of the support rods. Compared with the cylindrical-shaped support rods 8, the corrugated struts 8-1 have a stronger connection with the base concrete 4, and because the cylindrical-shaped structure has better buckling performance, the use of corrugated struts 8-1 can improve the seismic performance of the track support columns.
[0068] Alternatively, as shown in fig. 10, the tie bars are support rods 8 with thorns 8-2. Specifically, the thorns 8-2 are obliquely arranged on the support rods 8 and fixedly connected with the support rods 8. The thorns 8-2 are fixedly connected to the support rods 8 by welding, and the thorns 8-2 and the support rods 8 are arranged at an acute angle, as shown in fig. 10.
[0069] The track support columns of the present disclosure, when the upper track is subjected to vibration impact or wind load impact, the support rods 8 or the corrugated struts 8-1 of the track support columns can ensure the overall stability of the track, and at the same time can disperse impact force to weaken internal stress of the base concrete 4.
[0070] The specific steps of step 3 are as follows:
[0071] Further, in step 3, each of the track shear walls includes two second central support columns 14 and a beam 12, wherein, second concrete columns 15 are poured outside the second central support columns 14, and the beam 12 connects two second concrete columns 14; the two second concrete columns 15 and the beam 12 of each of the track shear walls are poured integrally.
[0072] Further, each of the track support columns includes a first central support column 3 and a first concrete column 2; the first concrete column 2 is poured outside the first central support column 3, and a rubber pad 6 is arranged above the first concrete column 2; the rubber pad 6 is arranged between the track concrete 1 and the first concrete column 2.
[0073] Specifically, step 31: the steps of pouring the track shear walls are as follows: a shear wall outer mold is installed outside two second central support columns 14, and concrete is poured in the shear wall outer mold to form second concrete columns 15 and the beam 12 outside the second central support columns 14. Remove the shear wall outer mold after pouring.
[0074] Specifically, step 32: the steps of pouring the track support columns are as follows: a column outer mold is installed outside the first central support column 3 at each of the track support columns, and the first concrete column 2 is poured in the column outer mold. Remove the column outer mold after pouring.
[0075] Step 4: the forming method between the support system and the track concrete includes the following steps:
[0076] step 41: a shear wall fixing plate 13 is arranged above two second central support columns 14 of each of the track shear walls; two ends of the shear wall fixing plate 13 are welded and fixed with two second central support columns 14; and the shear wall fixing plate 13 and the track concrete 1 are poured into a whole. Besides, the track concrete 1 and the beam 12 of each of the track shear walls are also poured into a whole.
[0077] Step 42: welding an upper fixing plate 5 at the upper end of the first central support column 3 of each of the track support columns; and pouring the upper fixing plate 5 and the track concrete 1 into a whole. Beside, install the rubber pad 6 between the track concrete 1 and the first concrete column 2, wherein, the rubber pad 6 is set outside the first central support column 3, realizing buffering impact and shock insulation through the rubber pad 6.
[0078] Further, the shear wall fixing plate 13 and the upper fixing plate 5 are all corrugated plates, and the ripple extension direction of the corrugated plates is consistent with the extension direction of the track concrete 1.
[0079] Compared with flat plate structure, the corrugated structure adopted by the present disclosure has better buckling performance. When the track is used, the track can be subjected to small bending deformation under the action of motion impact, and because the shear wall fixing plate 13 and the upper fixing plate 5 are corrugated metal plates, they can follow the deformation of the track, so that internal cracks between the fixing plate inside the track and track concrete are avoided, ensuring the overall stability of the track and prolonging the service life.
[0080] Consider that the performance of the rubber material is unstable, and the elastic performance of the rubber material is changed along with the temperature change; therefore, in order to realize the application of the ski track in the high-latitude low-temperature area, the elastic performance of the rubber pad 6 in the low-temperature environment needs to be ensured.
[0081] Furthermore, a protective cover 9 and temperature control lamps 10 are arranged outside each of the track support columns; the protective cover 9 is set outside the rubber pad 6, and the temperature control lamps 10 are embedded into side walls of the protective cover 9.
[0082] Specifically, as shown in fig. 4 to 6, the protective cover 9 is of a cylindrical structure, and the temperature control lamps 10 are mounted on the protective cover 9. Further, the temperature control lamps 10 are embedded on the side walls of the protection cover 9, as shown in fig. 5.
One side of the temperature control lamps 10 protrudes out of the inner walls of the protection cover 9, and the other side protrudes out of the outer walls of the protection cover 9, as shown in fig. 6. The part of the temperature control lamps 10 positioned on the inner side of the protective cover 9 can irradiate the rubber pad 6 to provide heat for the rubber pad 6, so that the performance is prevented from being influenced by too low temperature; the part of the temperature controlled lamps 10 located outside the protective cover 9 can provide illumination at night.
[0083] Further, considering that the ski tracks are mostly built in mountainous areas in frigid and temperate zones, even if the protection measures mentioned above are adopted, the rubber pad 6 still has the risk of aging after being used for a long time. In order to realize the replacement of the rubber pad 6, the rubber pad 6 of the present disclosure is a splicing structure composed of multiple fan parts.
[0084] Specifically, as shown in fig. 7 and 8, the rubber pad 6 is composed of multiple fan parts.
[0085] Preferably, there are four fan parts, as shown in fig. 8.
[0086] In a specific embodiment of the present disclosure, as shown in fig. 8, when the fan parts are assembled into the rubber pad 6, the plane parts of adjacent fan parts are fitted to each other, and first arc surfaces and second arc surfaces of the adjacent fan parts are respectively assembled into two coaxial cylindrical surfaces. Specifically, the first arc surfaces of the fan parts are attached to the first central support column 3; a first cylindrical surface formed by the first arc surfaces of the multiple fan parts are attached to the outer surface of the first central support column 3, as shown in fig. 8.
The second arc surfaces of the fan parts are aligned with the outer surface of the first concrete column 2. A second cylindrical surface formed by the second arc surfaces of the multiple fan parts is the lateral surface of the rubber pad 6.
[0087] Further, in order to fix the rubber pad 6 of the splicing structure, the present disclosure is also provided with limit structure. Specifically, a protruding part 21 is arranged on each of the track support columns, sleeves 23 are nested in the protruding part 21, and bolts 22 are installed in the sleeves 23; the bolts 22 extends out of the upper surface of the protruding part 21 and are used for limiting the rubber pad 6. Further, the height of the bolts 22 extending out of the protruding part 21 is smaller than the thickness of the rubber pad 6.
[0088] In implementation, when the rubber pad 6 needs to be replaced, the bolts 22 are lowered or detached, and the old rubber pad 6 is removed;
Insert the multiple fan parts of a new rubber pad 6 between the track concrete 1 and the first concrete column 2; the bolts 22 are screwed into the protruding part 21, the upper ends of the bolts 22 protrude out of the upper surface of the protruding part 21 and contact with the outer surface (i.e., the second cylindrical surface) of the rubber pad 6 to limit the rubber pad 6, so that tight adhesion between each part of the rubber pad 6 is kept, and the rubber pad 6 is prevented from moving and the whole structural form of the rubber pad 6 is kept not loose.
[0089] Compared with prior art, the technical scheme provided by the embodiment has at least one of the following effects:
[0090] 1. The method for forming a support system of a track adopts the track shear walls as a rigid support of the track main body (track concrete), and adopts the track support columns with the top provided with the rubber pads to flexibly support the track concrete; the track support system of the present disclosure realizes the support of the trace concrete by using the combination of the track shear walls and the track support columns, and this combination of rigid support and flexible support improves the impact resistance and overall stability of the track on the premise of ensuring the reliable support of the track concrete.
[0091] 2. The method for forming a support system of a track adopts the portal structure composed of double concrete columns and a beam as each of the track shear walls, and the track shear walls and track concrete are poured into a whole, so that the support system is more stably connected with the track main body; the portal structure track shear walls are used as rigid support of the track concrete to ensure the overall stability of the track.
[0092] 3. According to the method for forming a support system of a track, multiple sets of track support columns are arranged between two adjacent sets of track shear walls as flexible supports, and compared with the track shear walls, rubber pads are arranged between the concrete columns of the track support columns and the track concrete for vibration isolation and buffering. When the track is put into use, the flexible support columns allow minimal deformation of the main body of the track, and the rubber pads cushion the rigid impact between the track concrete and the concrete columns, ensuring the ductility and seismic performance of the track.
[0093] 4. According to the method for forming the track support column, multiple tie bars are fixed in the base concrete 4 and used for connecting the support columns, the shear walls and the base. The first central support column 3 or the second central support column 14 is fixed with the base concrete 4 into a whole through the lower fixing plate 7, and multiple tie bars, namely the support rods 8 or the corrugated struts 8-1 are arranged on the lower fixing plate 7. Multiple tie bars and the lower fixing plate 7 form a plant root-like structure system, so that the track support columns and the base concrete are connected more tightly. When the upper track is impacted by vibration or wind load, the tie bars can ensure the integral stability of the track, and can disperse impact force and weaken the internal stress of the base concrete.
[0094] The above is only preferred embodiments of the present disclosure and is not intended to limit the present disclosure, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
