Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction engineering, and in particular to a method for constructing an anti-skid groove of a cold branch pipe structure layer in a snow-covered area of a ski slope in an indoor ski resort. Background Art
[0002] With the promotion of ice and snow sports, ice and snow athletes in southern regions can play ice and snow sports in indoor ice and snow sports venues. Indoor ice and snow sports venues are generally large spaces with internal temperatures controlled below zero all year round. Due to the needs of building performance, a variety of thermal insulation layers such as hot branch pipe layers, vapor barriers, thermal insulation layers, isolation layers, cold branch pipe structure layers and snow layers are added to the beginner, intermediate and advanced ski slopes in the venue. Among them, anti-skid grooves need to be set in areas with a slope of more than 8° on the ski slope to facilitate subsequent snow covering. The current conventional anti-skid groove construction method not only poses a hidden danger of displacement of the cold branch pipe in the cold branch pipe structure layer due to vibration during concrete pouring, but also easily damages the cold branch pipe when the anti-skid groove is chiseled out after the concrete pouring of the cold branch pipe structure layer, and the structural performance of the cold branch pipe structure layer of the subsequent ski resort cannot be guaranteed. At the same time, the anti-skid grooves on the ski slopes are widely distributed and the number of construction areas is large. The conventional construction method leads to long construction time and consumes a lot of labor. Summary of the invention

[0012] Furthermore, the present invention provides a method for constructing an anti-skid groove for a cold branch pipe structure layer in a snow-covered area of a ski slope in an indoor ski resort, in which corresponding steel wires on each extruded polystyrene foam board are arranged at intervals of 250 mm along the length direction of the concrete dock.
[0013] Furthermore, the present invention provides a method for constructing an anti-skid groove in a cold branch pipe structure layer in a snow-covered area of a ski slope in an indoor ski resort, which removes the extruded polystyrene foam board from the upper concrete layer by cutting off the steel wire that fixes the extruded polystyrene foam board.

[0020] The invention provides a method for constructing an anti-skid groove for a cold branch pipe structure layer in a snow-covered area of a ski slope in an indoor ski resort. The method comprises the following steps: constructing the cold branch pipe structure layer in stages through upper and lower layers of concrete, and laying out an extruded polystyrene foam board on the lower concrete layer according to the planned position of the anti-skid groove through a concrete dock. After constructing the upper concrete layer, the extruded polystyrene foam board is removed, thereby forming an anti-skid groove for the cold branch pipe structure layer at the position where the extruded polystyrene foam board is removed from the upper concrete layer.

[0029] The present invention is described in detail below in conjunction with the accompanying drawings: The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0030] Please refer to Figures 1 to 6 The embodiment of the present invention provides a method for constructing an anti-skid groove in a cold branch pipe structure layer in a snow-covered area of a ski slope in an indoor ski resort, which may include the following steps:
[0031] Step S101, laying out the cold branch pipe 2 on the isolation layer 0 of a certain slope, such as Figure 2 As shown. The slope of the isolation layer 0 is greater than or equal to 8 degrees. The layout intervals of the cold branch pipes 2 can be the same.
[0032] Step S102, cover the cold branch pipe 2 to construct the lower concrete 1, make the slope of the lower concrete 1 the same as the slope of the isolation layer 0, and bury the cold branch pipe 2 in the lower concrete 1, such as Figure 2 The thickness of the lower concrete layer 1 can be 60 mm, which needs to be greater than the diameter of the cold branch pipe 2 so that the cold branch pipe 2 can be buried in the lower concrete layer 1 .
[0033] Step S103, on the lower concrete layer 1, the concrete dock 3 is used to lay out the extruded polystyrene foam board (i.e., XPS board) 4 according to the planned position of the anti-skid groove, so that the slope of the connecting line of each extruded polystyrene foam board 4 is the same as the slope of the lower concrete layer, such as Figure 3 As shown. The XPS board 4 can be replaced by other foam boards or wooden blocks. The concrete docks 3 can be arranged at intervals of 1000mm along the width direction of the primary, intermediate and advanced ski slopes. The length of a single concrete dock 3 can be 1000mm, the width can be 100mm, and the height can be 45mm. The width of the extruded polystyrene foam board 4 can be 30mm, and the height can be 30mm. The interval between adjacent extruded polystyrene foam boards 4 can be 200mm. In order to ensure the fixing effect of the extruded polystyrene foam board 4, the casting angle of the concrete dock 3 on both sides of the extruded polystyrene foam board 4 can be 45 degrees.
[0034] Step S104, each extruded polystyrene foam board 4 can be fixed on the lower concrete 1 by using the steel wire 5 and the self-tapping screws 6 wound around its two ends. Figure 4As shown. Specifically, each extruded polystyrene foam board 4 is arranged on the lower concrete 1 along the concrete dock 3 on both sides thereof by means of a steel wire 5, and the two ends of the steel wire 5 at the corresponding position of each extruded polystyrene foam board 4 are fixed on the lower concrete 1 by means of a wound self-tapping screw 6. In order to effectively fix each extruded polystyrene foam board 4, the corresponding steel wire 5 on each extruded polystyrene foam board 4 can be arranged in a row along the length direction of the concrete dock 3 at a spacing of 250 mm. The length of the steel wire 5 used to fix each extruded polystyrene foam board 4 can be 230 mm.
[0035] Step S105, cover the concrete dock 3, expose the extruded polystyrene foam board 4, construct the upper concrete 7, make the slope of the upper concrete 7 the same as the slope of the upper concrete 7 and make the upper surface of the upper concrete 7 flush with the upper surface of the extruded polystyrene foam board 4 to form a cold branch pipe structure layer 8. The thickness of the upper concrete 7 can be 60mm. The cold branch pipe structure layer 8 mainly includes the lower concrete 1 and the cold branch pipe 2 buried therein, the concrete dock 3 and the upper concrete 7. In order to ensure the stability of the concrete structure and the reliability of the connection and to be suitable for low temperature environment, the lower concrete 1, the concrete dock 3 and the upper concrete 7 are all made of antifreeze concrete.
[0036] Step S106, after the upper concrete layer 7 reaches the hardness condition, each extruded polystyrene foam board 4 is removed to form an anti-skid groove 81 of the cold branch pipe structure layer 8 at each position where the extruded polystyrene foam board 4 is removed from the upper concrete layer 7, such as Figure 6 In order to remove the extruded polystyrene foam board 4, the steel wire 5 fixing the extruded polystyrene foam board 4 can be cut by a cutting tool, and the extruded polystyrene foam board 4 can be cut to remove it from the upper concrete 7. Alternatively, the steel wire 5 fixing the extruded polystyrene foam board 4 can be cut by a hydraulic shearing tool, and the extruded polystyrene foam board 4 can be chiseled or dug out to remove it from the upper concrete 7. When the height and width of the extruded polystyrene foam board 4 are both 30 mm, the depth and width of the anti-skid groove 81 formed at this time are both 30 mm.
[0037] The steel wire 5 and the self-tapping screws 6 wound around its two ends fix each extruded polystyrene foam board 4 on the lower concrete layer 1, which can ensure that the position of the extruded polystyrene foam board 4 does not deviate during the construction of the upper concrete layer 7, thereby improving the position accuracy of the subsequent formation of the anti-slip groove 81.
[0038] The method for constructing an anti-skid groove of a cold branch pipe structure layer in a snow-covered area of a ski slope in an indoor ski resort provided by the present invention comprises the following steps: constructing the cold branch pipe structure layer 8 in stages through the upper and lower concrete layers 1, and laying out the extruded polystyrene foam board 4 on the lower concrete layer 1 through the concrete dock 3 according to the planned position of the anti-skid groove 81, and removing the extruded polystyrene foam board 4 after constructing the upper concrete layer 7, thereby forming the anti-skid groove 81 of the cold branch pipe structure layer 8 at the position where the extruded polystyrene foam board 4 is removed from the upper concrete layer 7, positioning the planned position of the anti-skid groove 81 by constructing the extruded polystyrene foam board 4 and fixing the extruded polystyrene foam board 4 through the concrete dock 3, and removing the extruded polystyrene foam board 4 after the upper concrete layer 7 is constructed. The construction process of directly chiseling the anti-skid groove 81 on the concrete structure of the cold branch pipe structure layer 8 according to the traditional method reduces the difficulty of constructing the anti-skid groove 81 on the concrete structure of the cold branch pipe structure layer 8, improves the construction efficiency of the anti-skid groove 81, shortens the construction period of the anti-skid groove 81, improves the construction quality of the anti-skid groove 81, reduces the labor intensity of manual labor, avoids the problem of traditional chiseling of the anti-skid groove 81 easily causing damage to the cold branch pipe 2, and ensures the structural performance of the cold branch pipe structure layer 8. Since the lower layer concrete 1 has reached the strength condition and the cold branch pipe 2 is buried therein, the vibration during the pouring and vibration of the upper layer concrete 7 will not cause displacement of the buried position of the cold branch pipe 2, thereby improving the accuracy of the buried position of the cold branch pipe 2.
[0039] The method for constructing an anti-skid groove on a cold branch pipe structure layer in a snow-covered area of a ski slope in an indoor ski resort provided by the present invention is suitable for constructing an anti-skid groove 81 on a cold branch pipe structure layer 8 with a slope of more than 8 degrees, and has quickness and flexibility in construction.
