The steel pipe pile installation assembly 100 provided by the application improves the hoisting efficiency of the steel pipe pile 110 and the steel pipe pile installation assembly 100 through the structural arrangement of the hoisting piece 1102 on the outer side wall of the steel pipe pile 110, and further improves the installation efficiency of the steel pipe pile 110. Furthermore, the outer side wall of the body 1201 of the pile driver 120 is in contact with the end surface of the steel pipe pile 110 in the circumferential direction, so that the end of the steel pipe pile 110 is effectively prevented from being damaged due to high pressure, and the working time is saved. In addition, the pile driver 120 in the embodiment of the application can effectively prevent the body 1201 of the pile driver 120 from falling off, and can also improve the installation efficiency of the steel pipe pile 110.

The specific structure and various possible embodiments of the steel pipe pile installation assembly 100 are described in detail below.

Illustratively, as shown in fig. 1, the steel pipe pile 110 in the present embodiment is a rotary member, the steel pipe pile 110 has a rotary cavity 1101, the rotary cavity 1101 extends along the axial direction of the steel pipe pile 110, and the rotary cavity 1101 penetrates opposite ends of the steel pipe pile 110 along the axial direction of the steel pipe pile 110. The outer side wall of the steel pipe pile 110 is provided with a hoisting member 1102, and the hoisting member 1102 may be provided at one end in the axial direction of the steel pipe pile 110 or may be provided at both ends of the steel pipe pile 110. At least two hoisting pieces 1102 are arranged at each end, and the two hoisting pieces 1102 are oppositely arranged along the radial direction of the steel pipe pile 110. This allows the steel pipe pile 110 to be balanced during handling. Furthermore, the same side of the hoisting member 1102 maintains a uniform axial position along the steel pipe pile 110 on the outer side wall of the steel pipe pile 110, so that the steel pipe pile 110 can be relatively stable when being hoisted in a horizontal state. The steel pipe pile 110 is convenient to hoist through the arrangement of the hoisting piece 1102 so as to improve the transportation and installation efficiency of the steel pipe pile 110.

In some other embodiments, the lifting member 1102 may be provided on the wall of the swing cavity 1101 of the steel pipe pile 110, so as to facilitate the lifting operation of the steel pipe pile 110 in the vertical state. Of course, the hoisting member 1102 may be disposed on the inner side wall and the outer side wall of the steel pipe pile 110 at the same time, so as to meet the hoisting requirements of the steel pipe pile 110 in different working environments. The number of the hoisting members 1102 and the relative positions of the hoisting members 1102 and the steel pipe pile 110 are selected and designed according to the actual operation requirements.

As shown in fig. 1 and 2, the body 1201 of the pile driver 120 in the present embodiment extends in the axial direction of the steel pipe pile 110, a first end of the body 1201 is inserted into the swivel chamber 1101 in the axial direction of the steel pipe pile 110, and a second end of the body 1201 extends outside the steel pipe pile 110. The circumferential outer side wall of the first end of the body 1201 abuts a part of the chamber wall of the swivel chamber 1101. A portion of the circumferential outer side wall of the second end of the body 1201 facing the swivel chamber 1101 abuts the end face of the steel pipe pile 110 opposite the pile driver 120. The second end of the body 1201 is a stress end 1203b, and the stress end 203 transmits the driving pressure to the steel pipe pile 110 under the action of the pile hammer, so that the steel pipe pile 110 is inserted into the foundation in the direction of the driving pressure. Illustratively, the direction of the pile driving pressure may be vertical or may have an included angle with the horizontal. In addition, the steel pipe pile installation assembly 100 changes in foundation with different working environment boxes. For example: in offshore operation, the foundation is the seabed or a mud layer formed on the seabed; when in land operation, the foundation is soil, rock, sand and the like.

As shown in fig. 1, the hoisting member 1102 in this embodiment includes a stop portion 1103 and a bearing portion 1104, and the bearing portion 1104 is connected between the stop portion 1103 and the outer side wall of the steel pipe pile 110. Illustratively, the bearing portion 1104 extends along the radial direction of the steel pipe pile 110, the first end of the bearing portion 1104 is connected to the outer side wall of the steel pipe pile 110, the second end of the bearing portion 1104 extends to the side away from the outer side wall of the steel pipe pile 110, and the second end of the bearing portion 1104 is connected to the stop portion 1103 relatively, so that a certain interval is formed between the stop portion 1103 and the outer side wall of the steel pipe pile 110 to enable the lifting rope to be hung on the bearing portion 1104.

To avoid sliding the lifting rope out of connection in the extending direction of the load bearing portion 1104, the radial dimension of the stop portion 1103 in the radial direction of the load bearing portion 1104 is larger than the radial dimension of the load bearing portion 1104 in the radial direction of the load bearing portion 1104, so as to limit the position of the lifting rope between the outer side wall of the steel pipe pile 110 and the stop portion 1103. Such a hoisting member 1102 can improve the safety and the hoisting efficiency of the hoisting operation of the steel pipe pile 110.

As shown in fig. 3 and 4, the load-bearing portion 1104 is a tubular member, a first end of the tubular member is connected to an outer side wall of the steel pipe pile 110, and a second end of the tubular member is connected to the stopper portion 1103.

Further, the side wall of the bearing part 1104 is provided with at least two cable positioning grooves 1105, the cross section of the cable positioning grooves 1105 is arc-shaped, the at least two cable positioning grooves 1105 are arranged at intervals along the radial direction of the steel pipe pile 110, and the cable positioning grooves 1105 are used for fixing a lifting rope. The lifting rope can be single, and single lifting rope can hang in cable constant head tank 1105 along the radial of bearing portion 1104, also can twine on bearing portion 1104, and the notch of lifting rope and cable constant head tank 1105 is relative. The number of the lifting ropes can be multiple, and each lifting rope is opposite to the cable positioning groove 1105. With such a structural arrangement, the connection of the lifting rope and the load-bearing portion 1104 is facilitated, so that the steel pipe pile 110 is convenient to lift and install.

In some other embodiments, the load-bearing portion 1104 includes at least two load-bearing arms 1106, the load-bearing arms 1106 being disposed at intervals along the radial direction of the steel pipe pile 110, a first end of the load-bearing arms 1106 being connected to the outer sidewall of the steel pipe pile 110, a second end of the load-bearing arms 1106 extending away from the outer sidewall of the steel pipe pile 110 along the radial direction of the steel pipe pile 110, and a second end of the load-bearing arms 1106 being connected to the stop portion 1103.

As shown in fig. 5, in this embodiment, three bearing arms 1106 are connected to the outer side wall of the steel pipe pile 110, and the three bearing arms 1106 are disposed at intervals along the radial direction of the steel pipe pile 110, so as to form a space for accommodating a hoisting rope along the radial direction of the steel pipe pile 110. Both ends of the load-bearing arm 1106 are welded to the outer wall of the steel pipe pile 110 and the stopper 1103, respectively.

Further, the stopper 1103 is a solid of revolution, the rotation axis of the stopper 1103 is along the radial direction of the steel pipe pile 110, the bearing arms 1106 are symmetrically arranged with respect to the center of the stopper 1103, and the extension lengths of the bearing arms 1106 along the radial direction of the steel pipe pile 110 are uniform.

As shown in fig. 6, the stop portion 1103 is a sphere, the rotation center axis of the sphere is along the radial direction of the steel pipe pile 110, the two bearing arms 1106 in this embodiment are symmetrically distributed along the radial direction of the steel pipe pile 110 relative to the rotation axis of the sphere, and the extending lengths of the two bearing arms 1106 along the radial direction of the steel pipe pile 110 are the same, so as to ensure that the stress of the hoisting piece 1102 at each position on the outer side wall of the steel pipe pile 110 is uniform when being connected with a hoisting rope, and the steel pipe pile 110 can be kept relatively stable during the hoisting operation.

In some embodiments, the stop 1103 comprises a stop plate, the stop plate being circular in profile and the stop plate being connected to the load bearing 1104 towards the face of the side of the steel pipe pile 110. The side of the stop plate facing away from the load bearing portion 1104 may be in contact with other structures, such as: transfer boats, and the like. The steel pipe pile 110 can be kept stable on the transfer vessel, and the steel pipe pile 110 is prevented from shaking in the transfer process. Of course, the profile of the stop plate may be other shapes than circular, such as square, and the radial dimension of the stop plate in the radial direction of the bearing portion 1104 is only required to be larger than the radial dimension of the bearing portion 1104, so that the structural requirements required for connecting the lifting rope and the lifting piece 1102 are ensured.

In some embodiments, the body 1201 includes an insertion section 1202 and a bearing section 1203 connected in sequence, the insertion section 1202 and the bearing section 1203 each extending along the axial direction of the steel pipe pile 110, the insertion section 1202 being located within the swivel cavity 1101, and the length of extension of the insertion section 1202 along the axial direction of the steel pipe pile 110 being less than the length of extension of the bearing section 1203 along the axial direction of the steel pipe pile 110. The first end of the load-bearing section 1203 and the insertion section 1202 are connected in the axial direction of the steel pipe pile 110, and the second end of the load-bearing section 1203 is the load-bearing end 1203b. The diameter of the bearing section 1203 is larger than the diameter of the insertion section 1202, so that a flange 1203a is formed on the end surface of the bearing section 1203 on the side facing away from the stressed end 1203b, and the flange 1203a abuts against the end surface of the steel pipe pile 110.

As shown in fig. 1 and 2, the pile driver 120 body 1201 in the present embodiment extends along the axial direction of the rotation chamber 1101, and it is understood that the insertion section 1202 is located in the rotation chamber 1101, and the bearing section 1203 extends to the outside of the rotation chamber 1101. The diameter of the bearing segment 1203 is greater than the diameter of the insertion segment 1202. A flange 1203a may be formed on the side of the bearing segment 1203 opposite the rotation chamber 1101. When the body 1201 is inserted into the rotary cavity 1101, the flange 1203a abuts against the end surface of the steel pipe pile 110 and the end surface of the steel pipe pile 110 on the side facing the pile driver 120. The force-receiving end 1203b of the side of the load-bearing section 1203 facing away from the swivel 1101 transmits a force to the steel pipe pile 110 by the pile hammer to move the steel pipe pile 110 in the axial direction, thereby inserting the steel pipe pile 110 into the foundation.

It should be noted that, the diameter of the bearing section 1203 is larger than the diameter of the rotary cavity 1101 and the diameter of the insertion section 1202, and the size relationship between the diameter of the bearing section 1203 and the outer diameter of the steel pipe pile 110 may be designed according to practical situations.

During actual operation, the worker finds that the vibration frequency of the insertion section 1202 of the pile driver 120 is high, which easily causes damage to the insertion section 1202, so that in order to reduce the frequency of the insertion section 1202 and improve the service life of the pile driver 120, the extension length (L1 labeled in fig. 2) of the insertion section 1202 of the pile driver 120 in the axial direction of the steel pipe pile 110 in the present embodiment is smaller than the extension length (L2 labeled in fig. 2) of the bearing section 1203 in the axial direction of the steel pipe pile 110.

Further, as shown in fig. 2, the diameter of the portion of the outer side wall of the insertion section 1202 on the side facing away from the load-bearing section 1203 gradually decreases in the axial direction of the steel pipe pile 110 toward the side facing away from the load-bearing section 1203. The end of the insertion section 1202 facing away from the load-bearing section 1203 is tapered to facilitate entry of the insertion section 1202 into the swivel chamber 1101 and exit of the swivel chamber 1101. And the frequency of vibration at the end of insertion section 1202 will also decrease, extending the useful life of pile driver 120.
