Description

Technical Field

[0001] The present application relates to the technical field of landscape trestle construction, and in particular to a landscape trestle steel pipe pile. Background Art

[0002] Landscape trestle bridges are mostly set up inside scenic spots and parks to facilitate tourists to view the scenery and cross the river. This plan requires the construction of landscape trestle bridges on both sides of the urban river. The existing residential buildings along the river are densely distributed, and the impact of construction on the surrounding environment needs to be considered.

[0003] The construction of the landscape trestle includes driving steel pipe piles on the riverbed, setting steel cages inside the steel pipe piles, pouring cement into the steel pipe piles, and then laying the bridge deck and installing the bridge deck system. Since the riverbed soil of the urban river is relatively soft and the foundation is relatively poor, the traditional steel pipe pile construction requires the use of longer steel pipe piles and driving them very deep to provide a sufficiently stable pile foundation. The construction time is long, the noise is very loud, and the impact on the environment is relatively large, so it needs to be improved. Utility Model Content

[0007] By adopting the above technical solution, the construction workers install the protection component on the steel pipe pile body, and then use the reaction frame to statically drive the steel pipe pile until the designed depth is reached. During the driving process of the steel pipe pile, the protection component restricts the anchoring component to be in a retracted state. The construction workers control the steel cage to align the driving component with the top of the steel pipe pile body, lower the steel cage, and the steel cage drives the driving component to move vertically downward. Until the driving component contacts the anchoring component, the gravity of the steel cage and the driving component drives the anchoring component to break through the restriction of the protection component, extend out of the steel pipe pile body and be inserted into the riverbed, thereby improving the stability of the steel pipe pile; compared with the prior art, the present application does not need to increase the driving depth of the steel pipe pile to improve the stability of the pile foundation of the landscape trestle; the construction speed is fast and the impact on the environment is small.

[0008] Optionally, the anchor assembly includes a plurality of anchors, and the plurality of anchors are arranged along the length direction of the steel pipe pile body. A protection assembly is correspondingly arranged for each anchor, and the driving assembly cooperates with each anchor in turn to drive the anchor to move.

[0009] By adopting the above technical solution, when lowering the steel cage, the driving assembly first cooperates with the anchor located above, and the anchor located above is inserted into the riverbed. Then the driving assembly and the steel cage pass through the anchor located above until they cooperate with the anchor located below, and the anchor located below is inserted into the riverbed. Anchoring is performed in multiple times along the length direction of the steel pipe pile body to improve the stability of the steel pipe pile body. The driving assembly cooperates with only one anchor at a time, the operation process is simple, the construction speed is fast, and the impact on the environment is reduced.

[0010] Optionally, the anchor comprises a plurality of anchor rods, and the plurality of anchor rods are arranged along the circumference of the steel pipe pile body; a sleeve is installed on the inner circumferential wall of the steel pipe pile body, and the end of the sleeve away from the circumferential wall of the steel pipe pile body is arranged toward the axis of the steel pipe pile body; the sleeve penetrates the circumferential wall of the steel pipe pile body, and the end of the sleeve close to the circumferential wall of the steel pipe pile body does not protrude from the outer circumferential wall of the steel pipe pile body; the anchor rod is inserted in the sleeve, and the outer circumferential wall of the anchor rod is slidably matched with the inner circumferential wall of the sleeve, and the length of the anchor rod is greater than the length of the sleeve; the protection component can limit the anchor rod from extending out of the outer circumferential wall of the steel pipe pile body, and the driving component can drive the anchor rod to break through the limitation of the protection component to protrude from the outer circumferential wall of the steel pipe pile body and be inserted into the riverbed.

[0011] Optionally, the anchor rod is arranged at an angle, and the end of the anchor rod away from the axis of the steel pipe pile body is inclined downward; a plug is installed at the end of the anchor rod close to the axis of the steel pipe pile body, and the plug is used to prevent the anchor rod from escaping from the casing; a water-blocking part is provided at the end of the anchor rod close to the plug, and the plug can press the water-blocking part against the end wall of the casing; when the anchor rod is in a retracted state, the plug is attached to the adjacent plug; and the driving assembly drives the anchor rod to move via the plug.

[0012] Optionally, the driving assembly includes a driving head, which is shaped like an inverted cone, and the side wall of the driving head slides with the end wall of the plug away from the anchor rod. When the driving head descends, the anchor rod is driven to move along the inner wall of the casing and extend out of the steel pipe pile body.

[0013] By adopting the above technical solution, when the protective component restricts the anchor rod to be in a retracted state, multiple plugs belonging to the same anchor piece are pressed against each other, and the anchor rod is difficult to slip out of the casing during the insertion process. When lowering the steel cage, the construction personnel lower the steel cage and the drive head, and the tip of the drive head is inserted between the four plugs. As the drive head descends, the side wall of the drive head transfers the weight of the steel cage and the drive head to the plug, and the plug drives the anchor rod downward along the length direction of the casing to break through the restriction of the protective component and be inserted into the riverbed. The water-blocking component can prevent water and sediment in the riverbed from entering the steel pipe pile body.

[0015] By adopting the above technical solution, before inserting the steel pipe pile, the construction workers tighten the waterproof rubber ring in the placement groove, and the waterproof rubber ring restricts the anchor rod to be in a retracted state. When the anchor rod is extended, the tip of the anchor rod can easily pierce the waterproof rubber ring and insert it into the riverbed. In this process, the waterproof rubber ring prevents water and sediment in the riverbed from entering the steel pipe pile body. The operation is simple, and the cost of the waterproof rubber ring is low.

[0016] Optionally, the wall thickness of the steel pipe pile body is set to 15 mm, and the thickness of the waterproof rubber ring is set to 4 mm.

[0018] Optionally, one of the anchoring members includes four anchoring rods, and the anchoring rods of adjacent anchoring members are staggered.

[0019] By adopting the above technical solution, four anchor rods can provide sufficient supporting force. Compared with setting more anchor rods, more holes need to be opened on the steel pipe pile, which will reduce the strength of the steel pipe pile body.

[0020] Optionally, a triangular iron is provided on the casing, one side of the triangular iron is connected to the inner peripheral wall of the steel pipe pile body, and the other side of the triangular iron is connected to the outer peripheral wall of the casing.

[0033] When lowering the steel cage 2, the driving assembly 4 first cooperates with the anchor 31 located above, and the anchor 31 located above is inserted into the riverbed. Then the driving assembly 4 and the steel cage 2 pass through the anchor 31 located above until they cooperate with the anchor 31 located below, and the anchor 31 located below is inserted into the riverbed. Anchoring is performed in multiple times along the length direction of the steel pipe pile body 1 to improve the stability of the steel pipe pile body 1.

The sleeve 312 is fixed to the steel pipe pile body 1 by welding, and the internal space of the steel pipe pile body 1 is connected to the outside through the sleeve 312. The anchor rod 311 is inserted into the sleeve 312, and the outer peripheral wall of the anchor rod 311 is slidably matched with the inner peripheral wall of the sleeve 312, and the length of the anchor rod 311 is greater than the length of the sleeve 312. A triangle iron 6 is arranged on the sleeve 312, and one side of the triangle iron 6 is connected to the inner peripheral wall of the steel pipe pile body 1 by welding, and the other side of the triangle iron 6 is connected to the outer peripheral wall of the sleeve 312 by welding.

[0036] The anchor rod 311 is tilted, and the end of the anchor rod 311 away from the axis of the steel pipe pile body 1 is tilted downward. A plug 313 is installed at the end of the anchor rod 311 close to the axis of the steel pipe pile body 1, and the plug 313 is fixed to the anchor rod 311 by welding. The width of the plug 313 is greater than the inner diameter of the sleeve 312 to prevent the anchor rod 311 from slipping out of the sleeve 312. A water blocking member 314 is provided at the end of the anchor rod 311 close to the plug 313, and the plug 313 can press the water blocking member 314 against the end wall of the sleeve 312.
