DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0017] This embodiment comprises two symmetrical L-shaped panels 2, each comprising vertical slats 3 and horizontal slats 4. The horizontal slats 4 are bolted vertically to the bottoms of the vertical slats 3, forming an L-shape. The distance between the two vertical slats 3 is equal to the thickness of the retaining wall 1. That is, the two vertical slats 3 are attached to the walls of the retaining wall 1 on both sides, and the bottom surfaces of the vertical slats 3 are lower than the top surface of the retaining wall 1. Support columns 5 are positioned downwardly from both ends of the bottom surface of the horizontal slats 4, each with a roller 6 at its bottom. The support columns 5 are preferably telescopic columns, allowing their height to be adjusted.

[0018] The front ends of the two vertical strips 3 are fixedly connected together by a connecting plate 7. The bottom surface of the connecting plate 7 is higher than the upper surface of the horizontal mortar joint, that is, the bottom surface of the connecting plate 7 must be higher than the upper surface of the mortar layer to be applied. The rear ends of the two vertical strips 3 are fixedly connected together by a movable scraping plate 8. A plurality of circular holes 9 are provided at the rear ends of the vertical strips 3 along the height direction of the vertical strips 3. Adjustment holes 10 corresponding to the circular holes 9 are provided at both ends of the movable scraping plate 8. The height of the movable scraping plate 8 is adjusted by adjusting the adjustment holes 10 and the circular holes 9, thereby adjusting the application thickness of the horizontal mortar joint. The movable scraping plate 8 is fixed together by bolts passing through the adjustment holes 10 and the circular holes 9. The bolts are not shown in the drawings.

[0019] The present invention utilizes the existing tension bolt holes on the retaining wall 1. During construction, several rows of horizontal tension bolt holes are left on the retaining wall 1 from top to bottom. The U-shaped chute 11 of the present invention is provided with threaded holes corresponding to the tension bolt holes. Several sections of the U-shaped chute 11 are symmetrically fixed by bolts at the tension bolt holes on both sides of the retaining wall 1. In the drawings of this embodiment, a section of the U-shaped chute 11 is fixed on each side of the retaining wall 1. The inner width of the U-shaped chute 11 is equal to the diameter of the roller 6. The roller 6 is placed in the U-shaped chute 11 and can roll forward along the U-shaped chute 11. In order to reduce the mass of the U-shaped chute 11, the U-shaped chute 11 is preferably made of plastic.

[0020] In this embodiment, a handle 12 is preferably provided upwardly in the middle of the movable scraping plate 8, and an armrest 13 is provided upwardly on the connecting plate 7, so as to facilitate pushing the tool forward by the handle 12 and pulling the tool forward by the armrest 13.

[0021] When in use, apply a mortar layer on the upper surface of the retaining wall 1, select the tension bolt holes of appropriate height to fix the U-shaped slide 11, and then place the rollers 6 on both sides in the U-shaped slide 11 on both sides, adjust the height of the movable scraping plate 8 according to the required mortar layer thickness, and fix the movable scraping plate 8 on the vertical strips 3 by bolts after adjustment, pull or push the tool forward along the U-shaped slide 11, and during the movement, the movable scraping plate 8 will complete the thickness, width and flatness of the horizontal mortar joints at one time. The thickness of the mortar layer is the vertical distance from the bottom surface of the movable scraping plate 8 to the upper surface of the retaining wall 1, and the width is equal to the thickness of the retaining wall 1. The excess mortar will fall into the U-shaped slide 11 on both sides and can be recycled again. After the horizontal mortar joint construction is completed, the capping stone can be installed on it.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
