Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a rubble stone retaining wall slope control device. Background Art

[0002] A rubble stone retaining wall is a retaining structure constructed with natural rubble stones or stones to resist the lateral pressure of the soil and prevent soil landslides or collapses. It is usually used in land engineering, road engineering, water conservancy engineering and other fields. The characteristic of a rubble stone retaining wall is that it uses natural rubble stones or stones and does not require processing or reinforcement. Usually, when a rubble stone retaining wall is constructed, its slope needs to be strictly controlled.

[0003] The patent with publication number CN211816390U proposes a slope control device for rubble stone retaining walls. By adjusting the position of the sliding sleeve on the bottom rod, the movable support rod is driven to pull the vertical rod to adjust the angle, so as to achieve the purpose of adjusting any slope. The hanging column on the vertical rod can be connected to a reference line, so that by referring to the reference line, it can be intuitively seen whether the slope of the retaining wall meets the requirements.

[0004] However, when the device is in use, the bottom rod is placed on the ground. Usually, when the rough stone retaining wall is initially constructed, the ground is muddy. If the ground is uneven, the bottom rod cannot be in a horizontal position, which will affect the accuracy of the inclination of the vertical rod. Secondly, the length of the vertical rod is limited. If the slope of the rough stone retaining wall is relatively long, the vertical rod can only serve as a reference for the slope of the bottom of the rough stone retaining wall, so further improvement is needed.

[0024] like Figure 1-Figure 4 As shown, it relates to a slope control device for a rubble stone retaining wall, comprising a base plate 1 and a plurality of reference rods 8, support assemblies 2 are installed at the four corners of the lower surface of the base plate 1, two mutually perpendicular spirit levels 3 are fixed to the upper surface of the base plate 1, two support plates 4 are fixed to one side of the upper surface of the base plate 1, the top ends of the two support plates 4 are rotatably connected with a rotating shaft 5, the surface of the rotating shaft 5 is fixedly connected with a swing rod 7, the surface of the swing rod 7 is fixed with a slope meter 6, the top end of the reference rod 8 and the top end of each swing rod 7 are fixed with a docking assembly 10, the bottom end of the reference rod 8 is provided with a slot 81 matching the docking assembly 10, and an adjustment assembly 11 for adjusting the inclination of the swing rod 7 is provided near the support plate 4 on the upper surface of the base plate 1.

[0025] like Figure 1-Figure 2 As shown, a plurality of hanging poles 9 are fixed at equal distances on the surface of each reference rod 8.

[0026] After two of the control devices are arranged on both sides of the rough stone retaining wall, a reference line can be connected to the hanging poles 9 of the reference rods 8 of the two control devices, and the reference line can be used to observe whether the slope of the rough stone retaining wall meets the requirements.

[0027] like Figure 1-Figure 3As shown, the docking assembly 10 includes an insert block 101, and grooves 102 are provided on both sides of the insert block 101. A spring 103 is fixedly connected to the inner wall of the groove 102, and a clamping rod 104 is fixedly connected to the other end of the spring 103. The insert block 101 can be inserted into the slot 81, and clamping holes 82 for clamping the clamping rod 104 are provided on both sides of the slot 81.

[0028] After the insert block 101 is inserted into the slot 81 , the clamping rod 104 is clamped into the clamping hole 82 under the elastic force of the spring 103 . Through this connection method, two adjacent reference rods 8 can be spliced ​​together, and a reference rod 8 can be docked with the rocker rod 7 .

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the adjustment assembly 11 includes two vertical plates 112 fixed to the upper surface of the base plate 1 and a worm gear 111 fixed to the surface of the rotating shaft 5.

The docking method of the two adjacent benchmark rods 8 is the same as the above method, until the length of the spliced ​​benchmark rod 8 is the same as the length of the slope of the rubble stone retaining wall, and then tie the benchmark line on the hanging column 9 on the surface of the benchmark rod 8 of the two devices, and refer to the benchmark line to control the construction slope of the rubble stone retaining wall.
