Description
Technical Field
[0001] The utility model relates to a stone retaining wall, in particular to a control mechanism for the slope of the inclined plane of the wall body when building the stone retaining wall. Background Technique
[0002] A stone retaining wall is a wall that relies on its own weight to resist the outer soil body. The inner vertical surface of the wall body is a vertical surface, and the outer side surface of the wall body is an inclined slope. Because of its simple structure, easy access to materials and simple construction, it is widely used in retaining walls and flood control retaining walls. The construction process of the existing stone retaining wall is divided into three steps: positioning and setting out, foundation trench excavation, and wall body masonry. First, according to the design drawings, measure and set out the plane position and longitudinal elevation of the retaining wall according to the center line and elevation points of the enclosure. Use RTK to find the proposed masonry section for the excavation boundary line and the control line of the retaining wall, and determine the inner and outer boundary lines of the wall body according to the measurement points, accurately determine the boundary line and starting and ending points of the retaining wall, and the positions of each expansion joint and settlement joint. The excavation of the retaining wall foundation trench is generally carried out by an excavator and assisted by manual work. During excavation, excavate according to the excavation boundary line, and carry out slope setting and slope repair according to the excavation depth. After excavation, use a light dynamic penetrometer to measure the bearing capacity of the foundation. After meeting the design bearing capacity, tamp the original soil and pour a cushion for sealing. Finally, carry out wall body masonry. The masonry materials are selected as block stones with uniform stone quality, not easily weathered, and no cracks. Before masonry, clean the dirt on the surface of the stones and moisten them with water. The construction of the stone retaining wall generally uses the mortar laying method. When masonry, first lay a layer of mortar, and then place the stones according to the size and position of the masonry. The larger gaps between the stones should be filled with mortar first, and then filled with crushed stone. The method of laying crushed stone mortar or dry filling crushed stone should not be used. Fill and tamp the vertical joints with mortar. The thickness of the mortar joint is 20 mm - 30 mm. The mortar should be full, and there should be no contact between the stones. During the masonry process, it is advisable to form a working layer with 2 - 3 layers of stones. The horizontal joints of each working layer should be roughly leveled, and the vertical joints should be staggered from each other. When laying in layers, use large stones for the lower layer. The size of each stone should be appropriate, and large-sized sheet stones should not be selected to masonry the lower part of the masonry body. At the outer edge of the corner, use larger and more square sheet stones to alternate with the inner layer for masonry. When building the wall body, in order to control the inner and outer slopes of the wall body, first make a slope frame with wood boards, and its slope is controlled according to the slopes of each section. Set the slope frame at both ends of the masonry wall section and pull a line to control the masonry slope. In order to ensure that the thickness of the masonry meets the design requirements, it is necessary to correct the hanging line position on the slope frame during masonry. Since the slope frame is generally slightly wider than the masonry wall, the hanging line will deform with the shaking of the slope frame, resulting in a large slope error in the masonry wall. How to develop a convenient control mechanism for the slope of the inclined plane of the stone retaining wall is a problem that needs to be solved on site. Summary of the Invention
[0003] The utility model provides a control mechanism for the slope of the inclined plane of a masonry stone retaining wall, and solves the technical problem of how to develop a convenient control mechanism for the slope of the inclined plane of a stone retaining wall.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A control mechanism for the slope of the inclined plane of a masonry stone retaining wall during masonry includes an inner masonry positioning control line and an outer masonry positioning control line of a pre-masonry stone retaining wall. The inner masonry positioning control line and the outer masonry positioning control line are arranged parallel to each other. An inner front vertical positioning pole and an inner rear vertical positioning pole are spacedly arranged on the inner masonry positioning control line. An outer front vertical positioning pole and an outer rear vertical positioning pole are spacedly arranged outside the outer masonry positioning control line. The connection line between the inner front vertical positioning pole and the outer front vertical positioning pole is perpendicular to the inner masonry positioning control line, and the connection line between the inner rear vertical positioning pole and the outer rear vertical positioning pole is perpendicular to the inner masonry positioning control line. A front-side top horizontal positioning link is connected between the top of the inner front vertical positioning pole and the top of the outer front vertical positioning pole, and a rear-side top horizontal positioning link is connected between the top of the inner rear vertical positioning pole and the top of the outer rear vertical positioning pole. An outer front positioning anchor is arranged at the intersection of the connection line between the bottom of the inner front vertical positioning pole and the bottom of the outer front vertical positioning pole and the outer masonry positioning control line. An outer rear positioning anchor is arranged at the intersection of the connection line between the bottom of the inner rear vertical positioning pole and the bottom of the outer rear vertical positioning pole and the outer masonry positioning control line. A front stay cable is connected between the outer front positioning anchor and the front-side top horizontal positioning link, and a rear stay cable is connected between the outer rear positioning anchor and the rear-side top horizontal positioning link. The inclination angle of the front stay cable is equal to the inclination angle of the rear stay cable, and the inclination angle of the front stay cable is the same as the inclination of the outer inclined surface of the pre-masonry stone retaining wall.
[0006] A horizontal positioning line for the inner vertical surface of the wall is connected between the inner front vertical positioning pole and the inner rear vertical positioning pole at the same height, and a horizontal positioning line for the outer inclined surface of the wall is connected between the front stay cable and the rear stay cable at the same height.
[0007] The inner front vertical positioning pole, the inner rear vertical positioning pole, and the horizontal positioning line for the inner vertical surface of the wall are all abutted against the inner vertical surface of the stone retaining wall; the front stay cable, the rear stay cable, and the horizontal positioning line for the outer inclined surface of the wall are all abutted against the outer inclined surface of the stone retaining wall.
[0008] The utility model constructs an internal and external positioning vertical rod and a horizontal rod to form a positioning skeleton system, and positioning lines are arranged on the horizontal rod and the internal positioning vertical rod. Through this mechanism, the control of the slope of the inclined surface of the stone masonry retaining wall can be effectively realized. After a section of masonry is completed, the whole mechanism can be moved according to the previously laid bottom edge line of the masonry to complete the masonry work of the next masonry section, that is, the control of the slope rates of other inclined surfaces is realized, the masonry quality is ensured, and the construction speed of the stone masonry retaining wall is greatly accelerated.
