Description

Technical Field

[0001] This utility model belongs to the technical field of road construction, specifically relating to a slipform for shaping asphalt concrete dams. Background Technology

[0002] In highway construction, asphalt concrete retaining walls along the road edges play a crucial role. They effectively prevent rainwater from flowing from the road surface to the sides of the roadbed, preventing erosion and damage, thus ensuring the stability and durability of the highway. However, due to a lack of effective shaping tools, problems such as inconsistent height and inaccurate slopes are prone to occur during the construction of retaining walls.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] like Figure 1-4 As shown, a slipform for shaping an asphalt concrete dam is disclosed. The slipform includes a shaping template 6, a compaction platform 1, an end frame 8, and a compaction hammer 5. The shaping template 6 is welded from steel plates, and its main body is an inverted trapezoidal groove corresponding to the dam 7, providing a forming space for the asphalt concrete and ensuring that the dam 7 maintains a stable shape during the pouring process. The compaction platform 1 is a square channel with an opening facing downwards. The compaction platform 1 can be made of channel steel or welded steel plate. The compaction platform 1 is placed upside down on top of the shaped template 6, and the lower edge of the compaction platform 1 abuts against the lower middle part of the shaped template 6. In addition, there are force transmission ribs 3 inside the compaction platform 1 that support the sides of the shaped template 6. The force transmission ribs 3 support the upper middle part of the side wall of the shaped template 6. The compaction hammer 5 has a flat surface corresponding to the compaction platform 1. It compacts the asphalt concrete inside the shaped template 6 by impacting the compaction platform 1. The compaction hammer 5 transmits the impact force to the asphalt concrete inside the shaped template 6 by impacting the compaction platform 1, so that the shaped template 6 is subjected to uniform force and achieves the compaction effect.

[0020] The end frames 8 are matched with the shaped formwork 6 in the formwork-like steel frame structure. The shaped steel frame structure has high strength and stability, and can provide reliable end support for the shaped formwork 6. The two end frames 8 are fixed to both ends of the shaped formwork 6 respectively, so as to provide stable support for the shaped formwork 6 during construction, prevent deformation of the shaped formwork 6, ensure the forming quality of both ends of the dam 7, and ensure the continuity and stability of the entire dam 7.

[0021] In this embodiment, the length of the shaping template 6 is 1.5-2.5m.

[0022] To ensure that the compaction force is fully applied to the formwork 6, the formwork 6 extends upwards on both sides to the lower surface of the compaction platform 1 and is connected to the force transmission plate 4. The force transmission plate 4 is welded and fixed to the extended parts on both sides of the formwork 6 and is correspondingly close to the compaction platform 1. This step increases the transmission area between the formwork 6 and the compaction platform 1, making them form a stable transmission structure. This allows the force transmission plate 4 to better transmit the impact force to the formwork 6 during the compaction process, ensuring that the asphalt concrete is uniformly compacted.

[0023] Furthermore, the force-transmitting rib 3 extends along the length of the shaping template 6. To prevent stress concentration between the force-transmitting rib 3 and the outer surface of the shaping template 6 caused by compaction, a flange corresponding to the outer surface of the shaping template 6 is provided along the lower edge of the force-transmitting rib 3. This increases the contact area between the force-transmitting rib 3 and the shaping template 6, thereby improving the force transmission effect. The end frame 8 is equipped with a pull ring 9. After compaction, the shaped template 6 can be lifted and the water-blocking dam 7 can be formed by the pull ring 9 of the end frame 8 at both ends. The end frame 8 includes two double angle steels 11 spliced ​​together in a herringbone shape. The angle of the end frame 8 is adapted to the shaped template 6. The lower surface of the double angle steel 11 is connected to the shaped template 6. The two can be fixed by welding.

[0024] In an optional embodiment, the main body of the compaction hammer 5 is an upward-opening channel steel. The channel steel structure has high strength and rigidity. A rubber pad 12 is attached to the lower surface of the channel steel, which can withstand a large impact force. A handle 10 extending longitudinally is provided in the middle of the channel steel, which is suitable for compacting asphalt concrete in the construction of highway edges.

[0025] The rubber pad 12 also serves as a buffer, reducing the rigid impact between the compaction hammer 5 and the compaction platform 1, lowering noise, and protecting the surfaces of the compaction platform 1 and the compaction hammer 5, thus extending their service life.

[0026] The length of the channel steel corresponding to the compaction hammer 5 is adapted to the width of the compaction platform 1 to ensure the force on the compaction platform 1 during the compaction process. Ribs 2 are provided on both sides of the compaction platform 1 to connect its top plate and side plate respectively. The length of the ribs 2 is adapted to the length of the compaction platform 1 to enhance the structural strength of the compaction platform 1.

[0027] During construction, asphalt concrete is laid according to the layout position. After the slipform is pushed into place, it is manually tamped on the compaction platform 1. Once the asphalt concrete has initially set, the slipform can be moved to the next construction section, which effectively improves construction efficiency. With the same resource input, its daily construction volume can reach 300 meters, far exceeding the 100 meters of traditional work efficiency, while also greatly improving the construction quality.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
