Description

Technical Field

[0001] The utility model relates to a water construction device, in particular to a pile gripper for temporarily fixing steel pipe piles. Background Technique

[0002] When constructing on water, a vibrating hammer is used to lift a steel pipe pile and position it, and the steel pipe pile is vibrated to a certain depth by the power drive of the vibrating hammer. Since the energy of the vibrating hammer is low, the steel pipe pile can only be driven to a very shallow depth, so a hydraulic hammer needs to be used to drive the steel pipe pile. During this process, after the vibrating hammer plants the pile, due to the thick original terrain covering layer and the small penetration depth of the steel pipe pile into the soil, if there are no appropriate positioning and pile stabilizing measures at this time, the steel pipe pile may not stand upright and may tilt or even tip over. In order to ensure the reliability of pile driving, it is necessary to temporarily fix and position the steel pipe pile. According to construction experience, usually two extended steel profiles are welded on the barge deck to temporarily limit and fix the steel pipe pile.

[0003] The existing construction methods usually adopt a single-layer steel structure as the fixing measure, but the single-layer structure is likely to cause the pile body to tilt, resulting in unilateral force, which may damage the original structure, there are certain risks, and this structure can only fix steel pipe piles with a single pile diameter. Summary of the Invention

[0004] Purpose of the utility model: The purpose of the utility model is to provide a pile gripper for temporarily fixing steel pipe piles that can stably fix steel pipe piles temporarily and is applicable to steel pipe piles with different diameters.

[0005] Technical solution: The pile gripper for temporarily fixing steel pipe piles of the utility model includes a horizontal rod and a longitudinal rod that form an overall framework. The horizontal rod includes a transverse rod and a vertical rod, and the transverse rod extends outward by a certain length to form an outer opening.

[0006] Preferably, fixing rods for fixing steel pipe piles are respectively erected between the extending ends of two transverse rods in the same horizontal plane, and a blocking rod with a top end higher than the upper-layer transverse rod is longitudinally arranged at the extending end of the transverse rod, and the blocking rod is used to prevent the fixing rod from detaching from the pile gripper.

[0007] Preferably, diagonal rods for strengthening the stability of the pile gripper are arranged in the rectangle formed by the horizontal rod and the longitudinal rod.

[0008] Preferably, a stiffening plate for strengthening the stability of the pile gripper is obliquely arranged at the position where the extending end of the transverse rod is in contact with the vertical rod, and the setting of the stiffening plate can also make the pile gripper applicable to steel pipe piles with different pipe diameters.

[0009] Preferably, the horizontal rod, the longitudinal rod and the diagonal rod are all made of double-layer 26# H-shaped steel welded together.

[0010] Preferably, the fixing rod is made of 5# channel steel.

[0011] Preferably, the blocking rod is made of two layers of No. 10 channel steel welded together.

[0012] Beneficial effects: Compared with the prior art, the utility model has the following remarkable advantages: (1) The utility model adopts a double-layer steel structure as a fixing measure to prevent the pile body from tilting and generating unilateral stress, and protects the structure of the original terrain covering layer from being damaged; (2) Through the design of the blocking rod and the fixing rod, the temporary fixing of steel pipe piles with different diameters can be realized.

[0016] The technical solution of the utility model will be further described below in conjunction with the embodiments.

[0017] As shown in the figure, the pile gripper for temporarily fixing steel pipe piles of the utility model includes a horizontal rod 1 and a longitudinal rod 2 that form an overall framework. The horizontal rod 1 includes a transverse rod 11 and a vertical rod 12, and the transverse rod 11 extends outward by a certain length to form an outer opening.

[0018] Fixing rods 3 for fixing steel pipe piles are respectively erected between the extending ends of two transverse rods 11 in the same horizontal plane. A blocking rod 4 with a top end higher than the upper-layer transverse rod 11 is longitudinally provided at the extending end of the transverse rod 11, and the blocking rod 4 is used to prevent the fixing rod 3 from detaching from the pile gripper.

[0019] An inclined rod 5 for strengthening the stability of the pile gripper is provided in the rectangle formed by the horizontal rod 1 and the longitudinal rod 2.

[0020] A stiffening plate 6 for strengthening the stability of the pile gripper is obliquely provided at the position where the extending end of the transverse rod 11 is in contact with the vertical rod 12. The setting of the stiffening plate 6 can also make the pile gripper applicable to steel pipe piles with different pipe diameters.

[0021] The horizontal rod 1, the longitudinal rod 2 and the inclined rod 5 are all made of two layers of No. 26 H-shaped steel welded together.

[0022] The fixing rod 3 is made of No. 5 channel steel.

[0023] The blocking rod 4 is made of two layers of No. 10 channel steel welded together.

[0024] The working principle of the pile holder of the utility model is as follows: The pile holder is welded at the edge of the barge deck so that the outer opening of the pile holder extends out of the hull. Move the two fixing rods on the pile holder to make the outer opening in an open state to accommodate the steel pipe pile. After the steel pipe pile is vertically installed, use a crane to lift the vibrating hammer and the steel pipe pile to the pile holder, and slowly lift the pile foundation into the outer opening of the pile holder. Let the pile foundation fall by its own weight until it no longer sinks. At this time, lower the vibrating hammer with the clamp opening facing the pile wall to complete the pile clamping.

[0025] The pile holder of the utility model is particularly suitable for the temporary positioning of steel pipe piles in the water-based hammering construction process of steel pipe piles. According to the different diameters of the steel pipe piles, adjust the position of the fixing rod 5# channel steel to realize the fixation of steel pipe piles with different pipe diameters; the diagonal design of the stiffener enables different diameter steel pipe piles to play a fixing role when entering the outer opening area.
