[0039] The realization of the objectives, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts are within the scope of protection of the present invention.

[0041] It should be noted that all directional indications (such as up, down, left, and right) in the embodiments of the present invention are only used to explain the direction of the movement in a specific posture (such as the attached Figure 2 The relative position relationship and movement conditions of the components below are shown. If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one of these features.

[0043] Moreover, the technical solutions between the various embodiments of the present invention can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] The present invention provides a template positioning device 1, such as Figures 1 to 3As shown, the template positioning device 1 includes a fixed plate 11, a height adjustment component 12, a horizontal adjustment component 13 and a positioning member 14, the fixed plate 11 is used to be installed at the bottom of the ditch 20; the height adjustment component 12 includes a vertical adjustment rod 121 and a first mounting seat 122 installed on the vertical adjustment rod 121, the vertical adjustment rod 121 is installed on the fixed plate 11, and the first mounting seat 122 is configured to be able to adjust the height of the first mounting seat 122 on the vertical adjustment rod 121; the horizontal adjustment component 13 includes a horizontal adjustment rod 131 and at least two second mounting seats 132 installed on the horizontal adjustment rod 131, the second mounting seat 132 is configured to be able to adjust the position of the second mounting seat 132 on the horizontal adjustment rod 131; the positioning member 14 is installed on the second mounting seat 132, and the positioning member 14 is snap-fitted with the top of the template 25.

[0045] Among them, the template 25 is placed on both sides of the ditch 20 respectively, and the height of the first mounting seat 122 on the vertical adjustment rod 121 is adjusted by the first mounting seat 122, so that the horizontal adjustment rod 131, the second mounting seat 132 and the positioning member 14 are driven to rise and fall through the first mounting seat 122, and finally the height of the positioning member 14 is adjusted. The position of the second mounting seat 132 on the horizontal adjustment rod 131 is adjusted by the horizontal adjustment rod 131, so as to adjust the position of the positioning member 14 in the horizontal direction. According to the position of the template 25 and the height of the template 25, the height of the first mounting seat 122 and the position of the second mounting seat 132 in the horizontal direction are adjusted, so that when the fixing plate 11 is placed at the bottom of the ditch 20, the positioning member 14 can complete the engagement with the top of the template 25, thereby positioning it, and then the fixing plate 11 is fixed. 11 is installed at the bottom of the ditch 20. On the one hand, the template positioning device 1 can be adjusted according to the height size of the template 25 and the placement position of the template 25, thereby increasing the application range of the template positioning device 1; on the other hand, after the positioning member 14 is engaged with the template 25, the first mounting seat 122 no longer moves relative to the vertical adjustment rod 121, and the second mounting seat 132 no longer moves relative to the horizontal adjustment rod 131. The first mounting seat 122 limits the upward movement of the template 25, and the second mounting seat 132 limits the left and right shaking of the template 25, thereby firmly fixing the template 25. The use of the template positioning device 1 to position the template 25 does not require a lot of manpower and relies on construction experience to place steel bar heads to ensure that the template 25 is firmly positioned. Therefore, the use of the template positioning device 1 to construct the ditch 20 saves manpower and has high versatility. It should be noted that, if Figures 1 to 3 and Figure 6As shown, the ditch 20 is divided into a clean water ditch 201 and a sewage ditch 202. The tunnel pavement 21 is formed with a 2% transverse slope through construction to guide sewage from the tunnel pavement 21 into the sewage ditch 202. A water blind pipe 22 is pre-buried in the side wall of the clean water ditch 201 near the primary branch 24. Water seeping from the primary branch 24 flows into the clean water ditch 201 through the water blind pipe 22. In addition, a water guide surface 23 is provided at the top of the side wall of the clean water ditch 201 near the primary branch 24 to guide water seeping from the primary branch 24 into the water blind pipe 22.

[0046] According to one embodiment of the present invention, the positioning member 14 can be a claw 14A, and a positioning boss 26 is provided on the top of the template 25. The claw 14A is engaged with the positioning boss 26. The claw 14A includes a mounting portion 141 and two limiting portions 142 spaced apart from the mounting portion 141. The mounting portion 141 and the limiting portions 142 cooperate to form a positioning cavity 17. The mounting portion 141 is installed at the bottom of the second mounting seat 132. The side of the mounting portion 141 facing away from the second mounting seat 132 is used to abut against the top surface of the positioning boss 26, and the two limiting portions 142 are respectively used to abut against the outer side walls of the positioning boss 26; the positioning member 14 can also be a positioning column, and a positioning groove engaged with the positioning column is provided on the top of the template 25. The bottom surface of the positioning column abuts against the bottom of the positioning groove, and the side wall of the positioning column abuts against the groove wall of the positioning groove, thereby limiting the up and down movement and left and right shaking of the template 25, ensuring that the template 25 is firmly positioned.

[0047] like Figure 1 、 Figure 2 and Figure 5 As shown, the second mounting base 132 includes an adjusting member 133 and a mounting member 134. The horizontal adjusting rod 131 is configured to adjust the position of the mounting member 134 in the horizontal direction. The mounting member 134 is configured to adjust the position of the adjusting member 133 in the vertical direction. The positioning member 14 is mounted on the adjusting member 133. The adjusting member 133 can adjust the height of the positioning member 14 through the mounting member 134, so that the height of each positioning member 14 can be adjusted separately, avoiding the situation where the top of the template 25 with a high height can abut against the bottom of the positioning member 14 due to height error of the template 25 or uneven terrain, thereby limiting the template 25 from shaking up and down, while the top of the template 25 with a low height cannot abut against the bottom of the positioning member 14. The positioning member 14 cannot effectively fix the template 25, resulting in reduced construction quality.

[0048] Furthermore, the mounting member 134 includes an adjusting nut 1341 and an adjusting portion 1342. The horizontal adjustment rod 131 is configured to adjust the horizontal position of the adjusting portion 1342. The side wall of the adjusting portion 1342 is provided with an adjusting cavity, and the bottom of the adjusting portion 1342 is provided with an adjusting hole connected to the adjusting cavity. The adjusting member 133 includes a fine-tuning portion 1331 and a connecting portion 1332 connected to each other. The outer wall of the fine-tuning portion 1331 is provided with a first external thread. The fine-tuning portion 1331 is used to pass through the adjusting hole and extend into the adjusting cavity. The adjusting nut 1341 is located in the adjusting cavity and is threadedly connected to the fine-tuning portion 1331 via the first external thread. The positioning member 14 is mounted on the connecting portion 1332 located outside the adjusting cavity. By rotating the adjusting nut 1341, the height of the positioning member 14 is adjusted through the fine-tuning portion 1331 and the connecting portion 1332 to ensure that the bottom surface of the mounting portion 141 can abut against the top surface of the positioning boss 26, thereby limiting the upward and downward shaking of the template 25.

[0049] According to one embodiment of the present invention, the fine-tuning portion 1331 can be a fine-tuning rod, which is provided with a plurality of fine-tuning holes. The plurality of fine-tuning holes are arranged at intervals along the extension direction of the fine-tuning rod. The positioning pin passes through the fine-tuning at different positions through the adjustment cavity, thereby adjusting the height of the positioning member 14.

[0050] like Figures 1 to 3 As shown, the outer wall of the vertical adjustment rod 121 is provided with a second external thread, and the first mounting seat 122 is threadedly connected to the vertical adjustment rod 121 via the second external thread. The first mounting seat 122 rotates relative to the vertical adjustment rod 121 to adjust the height of the first mounting seat 122. By providing the second external thread on the outer wall of the vertical adjustment rod 121 and threading the first mounting seat 122 with the vertical adjustment rod 121, the position of the first mounting seat 122 on the vertical adjustment rod 121 can be adjusted by rotating the first mounting seat 122, and the first mounting seat 122 can be prevented from moving up and down relative to the vertical adjustment rod 121 when the first mounting seat 122 is not rotated, thereby preventing the positioning member 14 from moving up and down and failing to reliably position the template 25.

[0051] According to one embodiment of the present invention, a plurality of height adjustment holes are provided on the vertical adjustment rod 121, and the plurality of height adjustment holes are spaced apart along the extension direction of the vertical adjustment rod 121. The first mounting seat 122 is slidably engaged with the vertical adjustment rod 121 to adjust the height position of the first mounting seat 122 on the vertical adjustment rod 121. A positioning hole is provided on the first mounting seat 122, and the first mounting seat 122 passes through the positioning hole and the height adjustment hole through a positioning pin, thereby limiting the movement of the first mounting seat 122 relative to the vertical adjustment rod 121, thereby preventing the positioning member 14 from moving up and down and failing to reliably position the template 25.

[0052] Furthermore, the template positioning device 1 also includes a height limiting assembly 15, which includes at least two height limiting members 151. The height limiting members 151 are threadedly connected to the vertical adjustment rod 121, and the at least two height limiting members 151 are respectively provided on the upper and lower sides of the first mounting seat 122 to limit the vertical movement of the first mounting seat 122 relative to the vertical adjustment rod 121. By providing height limiting members 151 on both the upper and lower sides of the first mounting seat 122, the up and down movement of the first mounting seat 122 relative to the vertical adjustment rod 121 is further limited, thereby preventing the positioning member 14 from moving up and down and failing to reliably position the template 25. According to a preferred embodiment of the present invention, there are two height limiting members, both of which are nuts and are respectively provided on the upper and lower sides of the first mounting seat 122.

[0053] like Figure 2 As shown, the horizontal adjustment rod 131 includes two mounting sections 1311, which are respectively mounted on opposite sides of the first mounting seat 122. The second mounting seat 132 is used to be mounted on the mounting sections 1311. When the adjustment range of the second mounting seat 132 remains unchanged, the use of two mounting sections 1311 instead of directly mounting a complete adjustment rod on the first mounting seat 122 saves materials, thereby reducing the cost of the template positioning device 1.

[0054] The outer wall of the mounting section 1311 is provided with a third external thread, and the second mounting seat 132 is threadedly connected to the mounting section 1311 via the third external thread. The second mounting seat 132 rotates relative to the mounting section 1311 to adjust the position of the second mounting seat 132 on the mounting section 1311. By providing the third external thread on the outer wall of the mounting section 1311 and threadedly connecting the second mounting seat 132 to the mounting section 1311, the position of the second mounting seat 132 on the mounting section 1311 can be adjusted by rotating the second mounting seat 132, or the second mounting seat 132 will not move left or right relative to the mounting section 1311 when the second mounting seat 132 is not rotated, thereby preventing the positioning member 14 from moving left or right and failing to reliably position the template 25.

[0055] According to one embodiment of the present invention, a plurality of horizontal adjustment holes are provided on the horizontal adjustment rod 131, and the plurality of horizontal adjustment holes are arranged at intervals along the extension direction of the horizontal adjustment rod 131. The second mounting seat 132 is slidably engaged with the mounting section 1311 to adjust the horizontal position of the second mounting seat 132 on the mounting section 1311. A positioning hole is provided on the second mounting seat 132, and the second mounting seat 132 passes through the positioning hole and the horizontal adjustment hole through a positioning pin, thereby limiting the movement of the second mounting seat 132 relative to the mounting section 1311, thereby preventing the positioning member 14 from moving left and right and failing to reliably position the template 25.

[0056] like Figures 1 to 3As shown, the template positioning device 1 also includes at least two horizontal displacement limiting assemblies 16, which include at least two displacement limiting members 161. The displacement limiting members 161 are threadedly connected to the mounting section 1311, and the at least two displacement limiting members 161 are respectively arranged on two sides of the second mounting seat 132 that are arranged opposite each other in the horizontal direction, so as to limit the horizontal movement of the second mounting seat 132 relative to the mounting section 1311. The displacement limiting assemblies are arranged in a one-to-one correspondence with the second mounting seats 132, so that each second mounting seat 132 is provided with a displacement limiting member 161 on both sides, further limiting the movement of the second mounting seat 132 relative to the mounting section 1311, thereby preventing the positioning member 14 from moving left and right and failing to reliably position the template 25. It should be noted that the displacement limiting member 161 can be a nut.

[0057] like Figure 1 、 Figure 2 and Figure 4 As shown, the mounting section 1311 includes a reinforced portion 1312 and a horizontal displacement adjustment portion 1313 that are interconnected. The cross-sectional dimensions of the reinforced portion 1312 in a direction perpendicular to the axial direction of the reinforced portion 1312 are larger than the cross-sectional dimensions of the horizontal displacement adjustment portion 1313. The reinforced portion 1312 is mounted on the first mounting seat 122, and the second mounting seat 132 is mounted on the horizontal displacement adjustment portion 1313. The provision of the reinforced portion 1312 increases the connection area between the mounting section 1311 and the first mounting seat 122, thereby strengthening the connection strength between the mounting section 1311 and the first mounting seat 122.

[0058] According to an embodiment of the present invention, Figure 2 As shown, the bottom surface of the fixing plate 11 is used to fit with the bottom of the ditch 20, and the fixing plate 11 is installed at the bottom of the ditch 20 by at least two fixing anchors 19. The fixing plate 11 is fixed to the bottom of the ditch 20 by at least two anchors 19 to enhance the stability of the fixing plate 11.

[0059] like Figure 2 and Figure 3 As shown, the template positioning device 1 also includes a turnbuckle 18 and a bolt fixing seat 27. The bolt fixing seat 27 is used to be installed at the bottom of the sewage ditch 202. One end of the turnbuckle 18 is used to connect to the template 25 located in the sewage ditch 202 and close to the clean water ditch 201, and the other end of the turnbuckle 18 is connected to the bolt fixing seat 27. The addition of the turnbuckle 18 cooperates with the positioning member 14 to position the template 25 located on the side wall of the sewage ditch 202 and close to the clean water ditch 201, thereby ensuring the construction quality of the clean water ditch 201.

[0060] In addition, the present invention also provides a ditch construction method, such as Figure 7As shown, the ditch construction method is a construction method using the above-mentioned template positioning device, and the ditch construction method includes:

[0061] S100, constructing a slope on the tunnel pavement to allow sewage on the tunnel pavement to flow into a sewage ditch;

[0062] The tunnel pavement is constructed to form a 2% transverse slope to facilitate the flow of sewage on the tunnel pavement into the sewage ditch.

[0063] S200, paving the bottom of the clean water ditch and the sewage ditch;

[0064] The bottom of the clean water ditch and sewage ditch is paved for subsequent construction.

[0065] S300, measuring and laying out the clean water ditch and the sewage ditch;

[0066] Measure and lay out the clean water ditch and sewage ditch to determine the placement of the template.

[0067] S400, placing the template into the clean water ditch and the sewage ditch according to the measurement data;

[0068] According to the measurement data, multiple templates are placed in the designated locations of the clean water ditch and sewage ditch respectively.

[0069] S500, installing the template positioning device, installing the fixing plate on the bottom of the clear water ditch; installing the positioning member on the template;

[0070] After placing the template in the designated position, rotate the first mounting seat to adjust the height of the positioning member, and then rotate the second mounting seat to adjust the horizontal position of the positioning member so that when the fixing plate is placed on the bottom of the ditch, the positioning member can be snapped into contact with the corresponding template, and then fix the fixing plate to the bottom of the ditch with at least two anchor nails, thereby completing the fixation of the template and ensuring construction quality.

[0071] S600, performing recheck measurement on the clean water ditch and the sewage ditch;

[0072] The clean water ditch and the sewage ditch are then measured to ensure the accurate position of the template, so as to avoid the template from being offset after positioning is completed and affecting the construction quality.

[0073] S700: burying a water-conducting blind pipe between the clear water ditch and the primary branch;

[0074] Since the primary branch will overflow water, a water blind pipe is pre-buried in the side wall of the clear water ditch close to the primary branch to guide the water overflowing from the primary branch into the clear water ditch.

[0075] S800, pouring concrete for the side walls of the clear water ditch;

[0076] The side walls are poured to strengthen the strength of the side walls.

[0077] S900, after a preset time interval, take out the positioning device and the template, and then sprinkle water on the clean water ditch and the sewage ditch.

[0078] The preset time is generally 24 hours. After an interval of 24 hours, the second mounting seat is rotated to allow the positioning member to release the positioning of the positioning boss so that the formwork can be separated from the concrete, and then the clean water ditch and sewage ditch are sprinkled with water for maintenance.

[0079] The first mounting seat is rotated to drive the horizontal adjustment rod, the second mounting seat and the positioning member to rise and fall through the first mounting seat, thereby finally realizing the adjustment of the height of the positioning member, and the second mounting seat is rotated to adjust the position of the positioning member in the horizontal direction. According to the position of the template and the height of the template, the height of the first mounting seat and the position of the second mounting seat in the horizontal direction are adjusted, so that when the fixed plate is placed at the bottom of the ditch, the positioning member can complete the engagement with the top of the template, that is, the bottom surface of the mounting portion abuts the top surface of the positioning boss, and the inner wall of the limiting portion abuts the outer wall of the positioning boss, thereby limiting the upward and downward movement and left and right shaking of the template, and then the fixed plate is installed at the bottom of the ditch to complete the alignment of the template. Positioning, on the one hand, the template positioning device can be adjusted according to the height size of the template and the placement of the template, thereby increasing the application range of the template positioning device; on the other hand, after the positioning piece is clamped with the template, the first mounting seat no longer moves relative to the vertical adjustment rod, and the second mounting seat no longer moves relative to the horizontal adjustment rod. The first mounting seat limits the upward movement of the template, and the second mounting seat limits the left and right shaking of the template, thereby fixing the template firmly. The use of the template positioning device to position the template does not require a lot of manpower and relies on construction experience to place the steel bar head to ensure that the template is firmly positioned. Therefore, the use of the template positioning device to construct the ditch saves manpower and has high versatility.
