DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] When implementing: Figure 1-5 As shown, a slot locator for a reinforcement cage of a mud wall pile foundation comprises: two clamping plates 1 and an adjusting screw 101, wherein a mounting plate 102 is fixedly connected to the surface of one clamping plate 1, and one end of the other clamping plate 1 is slidably connected to the surface of the mounting plate 102, and the adjusting screw 101 is arranged on one side of the clamping plate 1, and one end of the adjusting screw 101 is threadedly penetrated through the adjacent clamping plate 1 and is rotatably connected to the surface of the other clamping plate 1; an indicating structure 2, which is used to be arranged on the surface of the mounting plate 102, and the indicating structure 2 is used to indicate whether the reinforcement cage is installed in place; wherein the indicating structure 2 comprises an insert block 201 arranged on a side of the mounting plate 102 away from the clamping plate 1, and the cross-sectional shape of the insert block 201 is a right-angled trapezoid, and a pressure block 205 is arranged on the side of the insert block 201 away from the mounting plate 102, and one end of the pressure block 205 extends to the interior of the insert block 201 and is slidably connected to the inner wall of the insert block 201;

[0021] By rotating the adjusting screw 101, one of the clamps 1 moves toward the other clamp 1 under the action of the threaded connection therewith, and in this process, the mounting plate 102 can limit it to prevent the adjusting screw 101 from driving it to rotate together. In this process, the two clamps 1 can clamp the surface of the steel cage to achieve the effect of fixing the position of the locator, so that the indicating structure 2 faces the inner side of the mud protective wall. The right-angle trapezoidal setting of the plug block 201 facilitates the insertion of the plug block 201 between the steel cage and the inner side of the mud protective wall.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a slider is slidably connected to one side of the plug block 201 close to the mounting plate 102, a connecting plate 202 is fixedly connected to the top of the mounting plate 102, a threaded rod 204 is provided on the side of the connecting plate 202 away from the plug block 201, one end of the threaded rod 204 is threadedly penetrated through the connecting plate 202 and is rotatably connected to the surface of the slider, a guide rod 203 is fixedly connected to the surface of the plug block 201, the other end of the guide rod 203 penetrates through the connecting plate 202 and is slidably connected to the inner wall of the connecting plate 202, and the surface of the guide rod 203 is provided with evenly distributed scales The inner wall of the pressure block 205 is fixedly connected with a first spring 207, the other end of the first spring 207 passes through the pressure block 205 and is fixedly connected with the inner wall of the plug block 201, an indicator rod 208 is arranged on the top of the pressure block 205, a storage cavity 209 is provided inside the plug block 201, the indicator rod 208 is slidably connected with the inside of the storage cavity 209, the top of the indicator rod 208 is arranged in an inclined surface, and a through hole 206 connected with the storage cavity 209 is provided on the top of the plug block 201, and the aperture of the through hole 206 is larger than the diameter of the indicator rod 208;

[0023] The lower end of the indicator rod 208 passes through the pressure block 205 and is slidably connected to the inner wall of the pressure block 205. The inner wall of the indicator rod 208 is fixedly connected with a second spring 212. The lower end of the second spring 212 passes through the indicator rod 208 and is fixedly connected to the inner wall of the pressure block 205.

[0024] After being clamped on the steel cage by the joint action of the two clamping plates 1, the adjusting screw 101 and the mounting plate 102, the plug block 201 is driven away from the mounting plate 102 by rotating the threaded rod 204, so that the inner side of the mud protective wall can squeeze the pressure block 205. In this process, the pressure block 205 can compress the first spring 207 and drive the indicator rod 208 to slide along the inner wall of the storage cavity 209 until it moves to the connection between the storage cavity 209 and the through hole 206. At this time, the indicator rod 208 can be pushed through the through hole 206 through the plug block 201 under the action of the second spring 212 to prompt the staff that the inner side of the mud protective wall is fully fitted with the surface of the plug block 201. The staff can quickly understand the distance between the steel cage and the inner side of the mud protective wall by observing the scale line on the guide rod 203. By fixing four or more of the positioners on the surface of the steel cage to detect the distance between the steel cage and the inner side of the mud protective wall at multiple points, it can be understood whether the steel cage is aligned with the preset installation position.

[0025] like Figure 4 and Figure 5 As shown, the inner wall of the storage cavity 209 is provided with a limiting cavity 210, and the surface of the indicating rod 208 is fixedly connected with a sound-generating portion 211, and the sound-generating portion 211 is slidably connected with the inner wall of the limiting cavity 210;

[0026] When the indicator rod 208 passes through the plug block 201, it can drive the sound-generating part 211 to move upward synchronously, and then hit the inner wall of the limit cavity 210 to make a sound to remind the staff that the inner side of the mud protective wall is fully fitted with the surface of the plug block 201, avoiding excessive squeezing and causing inaccurate detection.

[0027] When the utility model is in use, after being clamped on the steel cage by the joint action of the two clamping plates 1, the adjusting screw 101 and the mounting plate 102, the insert block 201 is driven away from the mounting plate 102 by rotating the threaded rod 204, so that the inner side of the mud protective wall can squeeze the pressure block 205. In this process, the pressure block 205 can compress the first spring 207 and drive the indicator rod 208 to slide along the inner wall of the storage cavity 209 until it moves to the connection between the storage cavity 209 and the through hole 206. At this time, the indicator rod 208 can be pushed through the through hole 206 by the action of the second spring 212. The through hole 206 passes through the plug block 201 to remind the staff that the inner side of the mud protective wall is fully fitted with the surface of the plug block 201. The staff can quickly understand the distance between the steel cage and the inner side of the mud protective wall at that location by observing the scale line on the guide rod 203. By fixing four or more of the positioners on the surface of the steel cage to detect the distance between the steel cage and the inner side of the mud protective wall at multiple points, it can be understood whether the steel cage is aligned with the preset installation position, and after the pouring is completed, the positioner can be disassembled by releasing the limit of the splint 1 on the steel cage for reuse.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
