[0002] During the construction of cement-stabilized subbase and base layers in highways and municipal engineering projects, in order to ensure that the elevation of the top surface of the paving layer meets the design and construction requirements, it is necessary to drive elevation control piles (usually using steel bars) downward at a certain distance from the top surface of the roadbed, and then hang the construction elevation control line on the control piles to control the thickness of the paving layer and the construction elevation.

[0003] When construction workers hung the control line, the elevation control line was directly hung on the steel control pile, which resulted in a large construction error, which in turn caused delays in the road paving construction progress, errors in the elevation control line adjustment, and errors in paving thickness.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1 A wire hanging device for water-stable layer paving construction comprises an elevation control rod 1. The elevation control rod 1 comprises an upper threaded rod 101 and a lower smooth rod 102. The threaded rod 101 and the smooth rod 102 are detachably connected.

[0024] In this embodiment, the end of the threaded rod 101 connected to the smooth rod 102 is provided with a cylindrical connecting column 103, and the outer surface of the connecting column 103 is provided with an external thread. The end of the smooth rod 102 connected to the threaded rod 101 is formed with a connecting hole 104, and the hole wall of the connecting hole 104 is provided with an internal thread that matches the external thread of the connecting column 103. The smooth rod 102 and the threaded rod 101 are threadedly connected in the connecting hole 104 through the connecting column 103. In addition, the end of the smooth rod 102 away from the connecting hole 104 is constructed as a pointed end. When not in use, a rubber protective sleeve 4 can be set on the connecting hole 104, the end of the connecting column 103 and the tip of the smooth rod 102, so as to better protect the operator from being stabbed by the tip of the smooth control rod and the exposed thread head at the end of the threaded screw control rod from being broken, thereby fully ensuring the operating safety of the operator.

[0025] The separate design of the bare rod 102 and the threaded rod 101 can achieve that when fixing the elevation control rod 1, a hammer cap 5 is first installed at the end of the bare rod 102. The hammer cap 5 is welded by a discus with a diameter of 5 cm + an iron pipe with a diameter of 1.8 cm and a wall thickness of 3 mm. When the control rod is inserted, the hammer cap 5 is buckled on the top of the rod body, and the rod body is hammered into the soil with a hammer head, which increases the hammering area and eliminates the risk of hand injuries to operators.

[0026] The end of the bare rod 102 is pointed and has a smooth surface, so it can be inserted into the roadbed smoothly and quickly, and it can also reduce the situation where the elevation control rod 1 cannot be pulled out. And only need to hit the bare rod 102, can effectively avoid the control rod from bending and deforming due to the rod body being too long during the hammering process. This kind of control rod is designed into two sections, and the hidden danger of rod body deformation and damage is eliminated by shortening the length of the control rod, further ensuring the service life of the rod, and ensuring the construction accuracy, further promoting the qualified rate of water-stabilizing layer construction, and avoiding the disadvantage of causing large-scale rework.

[0027] A wire hanging bracket 2 and a limiting mechanism 3 for installing the wire hanging bracket 2 on the elevation control rod 1 are provided on the threaded rod 101. The limiting mechanism 3 includes a positioning nut 301 and a limiting nut 302 which are threadedly connected to the elevation control rod 1 and arranged up and down. The wire hanging bracket 2 includes a bracket body 201 which forms a rotation limit with the positioning nut 301 and a cantilever bracket 202 located on one side of the bracket body 201 for hanging the wire. The bracket body 201 includes a sleeve cylinder 203 sleeved on the positioning nut 301 and a clamping cap 204 arranged on the inner side of the sleeve cylinder 203. The limiting nut 302 presses the clamping cap 204 onto the upper end face of the positioning nut 301. A clamping cap hole 212 is provided in the middle of the clamping cap 204 for the elevation control rod 1 to pass through.

[0028] In this embodiment, the inner surface of the sleeve cylinder 203 and the outer surface of the positioning nut 301 are circumferentially limited and axially slidably matched, and the cap 204 is integrally formed with the sleeve cylinder 203 and the upper end surface is flush with the upper end surface of the sleeve cylinder 203. The positioning nut 301 is a hexagonal nut or an octagonal nut. The positioning nut 301 not only plays a role in determining the height, but also has a certain directional effect. The construction personnel can more intuitively judge whether the cantilever bracket 202 is perpendicular to the elevation line according to the angle of the outer wall plane or corner of the positioning nut 301 toward the elevation line. Compared with the positioning nut 301, or estimate the angle between the length direction of the cantilever bracket 202 and the elevation line, preferably an octagonal nut, which can reduce the maximum angle of the cantilever bracket 202 compared to the elevation line.

[0029] When the bracket body 201 is sleeved on the positioning nut 301, the lower end of the positioning nut 301 extends out of the sleeve barrel 203, so as to facilitate the rotation of the positioning nut 301. Of course, the wire hanging bracket 2 can also be used as a wrench to directly rotate the positioning nut 301 to adjust the height of the positioning nut 301, and then the positioning nut 301 is used to set the reference to achieve accurate adjustment of the wire hanging position. The positioning nut 301 and the wire hanging bracket 2 form a circumferential limit to prevent the wire hanging bracket 2 from turning, and then the wire hanging bracket 2 is pressed by the limit nut 302, which can further prevent the positioning nut 301 from rotating due to the pulling effect.

[0030] Compared with the existing form of directly hanging the wire hanging bracket 2 on the steel bar control pile, the form of installing the wire hanging bracket 2 by means of the positioning nut 301 and the limiting nut 302 in this embodiment can effectively ensure that there is no loosening and sliding, so that the elevation will not change after the first adjustment, and even under the pulling action of the elevation line, there will basically be no problem that the wire hanging bracket 2 and the positioning nut 301 will rotate to affect the elevation accuracy, and the operation of manually assisting the paver probe rod to re-reset to the line after crossing the control pile is eliminated.

[0031] And if the positioning nut 301 rotates downward, the limit nut 302 can serve as an elevation reference. The positioning nut 301 can be directly screwed upward to make the line hanging bracket 2 fit the limit nut 302. There is no need to re-measure and adjust. The operation is relatively simple, which can greatly improve the line hanging efficiency during the entire construction process.

[0032] In this embodiment, the cantilever bracket 202 includes a fixed end 209 connected to the bracket body 201 and an extension end 210 extending radially along the bracket body 201. The thickness of the cantilever bracket 202 gradually increases from the extension end 210 to the fixed end 209. The upper and lower end surfaces of the extension end 210 are each provided with at least one hanging groove 211 for the elevation control line to be inserted into. The hanging grooves 211 on the upper and lower end surfaces of the extension end 210 are arranged alternately.

[0033] The wire hanging bracket 2 mainly supports the elevation control line and is made of cast iron or plastic steel. The thickness of the cantilever bracket 202 gradually increases from the extension end 210 to the fixed end 209, forming a crescent shape, which can effectively increase the bearing capacity of the cantilever bracket 202 component and fully meet the control line hanging requirements.

[0034] The setting of the hanging groove 211 can limit the elevation line so that the elevation line is stuck in the hanging groove 211. In this embodiment, three hanging grooves 211 and two hanging grooves 211 are respectively set on the upper and lower end faces of the extension end 210. When hanging the wire rope, the wire rope control line is tightened and then wrapped into the limiting card groove 206 at the cantilevered end of the support bracket. Each control pile support bracket is wrapped with two and a half turns. The control line on the first two control piles needs to be wrapped and knotted for multiple turns, which can ensure that the wire rope control line between the two elevation control piles is in a taut state, avoiding the wire rope suspended between the piles from appearing a downward supporting parabola.

[0035] This embodiment provides a wire hanging method for water-stable layer paving construction, which is implemented by using the aforementioned wire hanging device for water-stable layer paving construction, and specifically includes the following steps: Step S1, determining the insertion line of the elevation control rod 1 according to the paving construction width of the water-stable layer, the installation position of the side template of the water-stable layer, the width of the paver and the length of the paver induction probe rod 6, and determining the insertion position of a single elevation control rod 1 on the insertion line according to the established control rod spacing; Step S2, inserting the lower end of the polished rod 102 into the roadbed by hammering; Step S3, installing the threaded rod 101 on the upper end of the polished rod 102; Step S4, threading the positioning nut 301 onto the screw rod and placing the positioning nut 301 at a preliminary elevation position, which can be determined based on on-site construction experience or a predetermined elevation position; Step S5, sleeve the wire hanging bracket 2 onto the positioning nut 301 from top to bottom; Step S6, using the cantilever bracket 202 as a level gauge support pile, after measuring the current elevation of the top surface of the cantilever bracket 202, the height of the cantilever bracket 202 is adjusted by screwing the positioning nut 301 to adjust it to the precise design elevation position; Step S7, tighten the limiting nut 302 downwards so that the limiting nut 302 is pressed against the upper end surface of the positioning nut 301; Step S8, wrap the elevation control line point by point around the cantilever bracket 202 and put it into construction use, so that during the entire operation of the paver, its sensing probe rod 6 slides on the elevation control line without the need for span adjustment interference, thereby ensuring the construction quality and accuracy of the water-stabilized paving throughout the entire process.

[0036] Example 2 The same as Example 1, except that in this embodiment, the outer surface of the clamping cap 204 is connected to the inner surface of the sleeve cylinder 203 through the bearing 205 and the upper end surface is flush with the upper end surface of the sleeve cylinder 203, the inner surface of the clamping cap 204 and the positioning nut 301 form a circumferential limit, the inner surface of the sleeve cylinder 203 and the outer surface of the positioning nut 301 are slidingly matched, and the middle and edge parts of the limiting nut 302 are respectively pressed on the upper end surface of the clamping cap 204 and the upper end surface of the sleeve cylinder 203.

[0037] A groove 206 with a polygonal cross section is provided in the middle of the lower end surface of the cap 204, and a boss 207 extending into the groove 206 and matching the shape of the groove 206 is provided at the upper end of the positioning nut 301. The outer surface of the lower end of the positioning nut 301 and the inner surface of the sleeve cylinder 203 are both arc surfaces and can rotate relative to each other.

[0038] A circular rubber gasket 208 is disposed on the lower end surface of the limiting nut 302 , and the middle portion and the edge portion of the circular rubber gasket 208 are disposed opposite to the upper end surface of the clamping cap 204 and the upper end surface of the sleeve cylinder 203 , respectively.

[0039] This embodiment provides a wire hanging method for water-stable layer paving construction, which is implemented by using the aforementioned wire hanging device for water-stable layer paving construction, and specifically includes the following steps: Step S1, determining the insertion line shape of the elevation control rod 1 and the insertion position of the single elevation control rod 1 according to the paving construction width of the water-stable layer, the installation position of the side template of the water-stable layer, the width of the paver and the length of the paver induction probe rod 6; Step S2, inserting the lower end of the polished rod 102 into the roadbed by hammering; Step S3, installing the threaded rod 101 on the upper end of the polished rod 102; Step S4, threading the positioning nut 301 onto the screw rod and placing the positioning nut 301 at a preliminary elevation position; Step S5, sleeve the wire hanging bracket 2 onto the positioning nut 301 from top to bottom; Step S6, using the cantilever bracket 202 as a level gauge support pile, after measuring the current elevation of the top surface of the cantilever bracket 202, the height of the cantilever bracket 202 is adjusted by screwing the positioning nut 301 to adjust it to the precise design elevation position; Step S7, adjusting the direction of the cantilever bracket 202 to make it precisely perpendicular to the elevation line; Step S8, tighten the limiting nut 302 downwards, so that the limiting nut 302 is pressed against the clamping cap 204 and the upper end surface of the sleeve cylinder 203; Step S9, wrapping the elevation control line point by point around the cantilever bracket 202 and putting it into use for construction; Step S10: single-point adjust the height of the positioning nut 301 as required.

[0040] In this embodiment, not only the convenient adjustment of the elevation before hanging the wire can be realized, but also the convenient adjustment after hanging the wire can be realized. Specifically: In this embodiment, the cap 204 and the sleeve cylinder 203 are connected by a bearing 205, that is, the two can realize relative rotation. During the construction process, before hanging the line, the positioning nut 301 is screwed, and the positioning nut 301 drives the entire hanging line bracket 2 to move up and down to adjust the height of the hanging bracket, so that it can accurately reach the elevation position.

[0041] When reaching the position, first rotate the sleeve cylinder 203 relative to the clamping cap 204, that is, relative to the positioning nut 301, so that the cantilever bracket 202 can be accurately and vertically oriented towards the paver, ensuring that the cantilever bracket 202 and the paver sensing rod can be in the same length direction, which is a prerequisite for subsequent precise detection and can avoid a series of problems caused by uneven force on the elevation lines on both sides of the cantilever bracket 202 due to the rotation of the cantilever bracket 202, such as affecting the hanging accuracy and service life of the entire hanging device.

[0042] Then, the limiting nut 302 is used to limit the position. The limiting nut 302 simultaneously presses the clamping cap 204 and the sleeve cylinder 203 to prevent the two from rotating relative to each other, and under the circumferential limitation of the clamping cap 204 and the positioning nut 301, the entire wire hanging bracket 2 cannot rotate, thereby achieving a directional effect on the cantilever bracket 202 to ensure that it can always be perpendicular to the elevation line.

[0043] In order to ensure that the limiting nut 302 can simultaneously press the clamping cap 204 and the sleeve cylinder 203, a circular rubber gasket 208 is arranged at the bottom of the limiting nut 302, and the limiting nut 302 and the positioning nut 301 are designed to be reverse threads. This flexible pressing method can effectively improve the problem that the clamping cap 204 and the sleeve cylinder 203 may not be on the same upper plane due to the matching accuracy and cannot be pressed at the same time. At the same time, the circular rubber gasket 208 can also increase the friction force, further realizing the synchronous limiting of the two, so that they cannot rotate relative to each other.

[0044] Finally, when the line hanging position needs to be changed according to construction requirements after hanging the line, there is no need to remove the entire device, but it can be adjusted directly on the threaded rod 101. It is only necessary to screw the limit nut 302 to release the limit between the clamping cap 204 and the sleeve cylinder 203. The internal sleeve cylinder 203 can rotate relative to the clamping cap 204. At this time, when screwing the positioning nut 301 to change its height, it will not be difficult to screw it due to the tension of the elevation lines on both sides. Even in the hanging state, it is possible to better change the height of one or more positioning nuts 301 to adjust the point elevation line position.

[0045] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0046] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
