Description

Technical Field

[0001] The invention relates to the technical field of steel pipe pile construction, and in particular to a steel pipe pile punching device capable of rapid turnover. Background Art

[0002] When constructing steel pipe piles in relatively hard soil or soil with large friction resistance, the friction force is large because both the inside and outside of the steel pipe piles are embedded in the soil, and the construction speed of inserting into the soil is slow. In order to speed up the construction speed, the construction is usually carried out by the lead hole method, that is, the steel pipe pile is first inserted into the soil and pulled out at the construction point of the steel pipe pile through the water jet mother pile to loosen the soil layer, and then the steel pipe pile is inserted again in the original position. The two constructions also waste construction time.

[0003] The main purpose of drilling holes is to loosen the soil, but after the drilling is completed, the soil layer will still be affected by construction vibration, resulting in hole collapse or secondary compaction, which still poses a certain resistance to the in-situ construction of steel pipe piles.

[0004] Steel pipe piles come in a variety of sizes and models. When the construction site involves steel pipe piles of different diameters, multiple sets of drilling equipment of different models are required, which makes on-site management more complicated.

[0005] The specification requires that the verticality of steel pipe piles should be monitored before and during construction to ensure the quality of the piles. However, the specification does not have relevant requirements for bored piles. If the verticality is not properly controlled during the bored pile, it will affect the verticality quality control of the steel pipe piles. If the verticality of bored piles is measured, it will also increase the burden on on-site management personnel.

[0006] Therefore, the present invention proposes a steel pipe pile punching device that can be quickly turned around. Summary of the invention

[0007] The purpose of the present invention is to solve the defects in the prior art and to propose a steel pipe pile punching device with fast turnover.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A steel pipe pile punching device with fast turnover comprises a main frame, the main frame comprises a pile head fixing ring, an intermediate fixing ring, and a vertical fixing rod, the vertical fixing rod is multiple, and a pile head fixing ring and multiple intermediate fixing rings are installed on the outer sides of the multiple vertical fixing rods, the pile head fixing ring is located at the upper part of the vertical fixing rod, and the multiple intermediate fixing rings are all located at the vertical fixing rod below the pile head fixing ring, and the vertical fixing rod is detachably installed with the pile head fixing ring and the intermediate fixing ring respectively;

[0010] A plurality of water pipes are also provided inside the main body frame, and a high-pressure water pump is externally connected to the upper part of each water pipe, and a high-pressure spray head is detachably installed at the lower part of each water pipe;

[0011] A plurality of first nuts are fixed on the upper side of the pile head fixing ring, and first bolts are threadedly installed on all the first nuts;

[0012] A plurality of water pipe fixing rings are installed on the inner ring surface of each intermediate fixing ring, and the water pipes are fixed on the inner ring of the fixing ring through the water pipe fixing rings;

[0013] A wireless inclinometer is installed on the side surface of the vertical fixing rod.

[0014] Further, a plurality of second nuts are fixed on the upper sides of the pile head fixing ring and the intermediate fixing ring, and third nuts are fixed on the side surface of the vertical fixing rod at positions corresponding to the pile head fixing ring and the intermediate fixing ring, and second bolts are jointly installed on the second nuts and the third nuts on the same side.

[0015] Further, a plurality of pulleys are installed on the outer ring surface of each intermediate fixing ring, and the pulleys are in sliding contact with the inner surface of the steel pipe pile.

[0016] Further, a support frame is fixed at the center of the pile head fixing ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention adopts the form of being embedded in the steel pipe pile in advance and placed in the steel pipe pile in advance. While driving the steel pipe pile, the high-pressure water flow for hole leading and the insertion of the steel pipe pile are carried out simultaneously, and the pile can be formed at one time. There is no problem of reduced efficiency in first constructing the hole leading and then constructing the steel pipe pile, nor the problem of the soil body being re-compacted due to sequential construction, and the construction speed is greatly accelerated.

[0019] 2. The aperture of the hole that can be punched by the present invention is adjustable, and it can be quickly replaced by replacing the pile head fixing ring and the intermediate fixing ring, without the need to prepare multiple sets of punching devices on site, thus facilitating management.

[0020] 3. The built-in wireless inclinometer in the present invention not only avoids repeated measurement of the verticality during two insertions, but also makes it more convenient for on-site construction management personnel to measure and control the quality.

[0021] 4. The present invention can adjust the water pressure and the size of the water flow by replacing the high-pressure spray head to loosen the soil body in the hole under different geological conditions and expand the scope of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention;

[0032] Reference Figure 1-7 A steel pipe pile punching device with fast turnover includes a main frame, characterized in that the main frame includes a pile head fixing ring 1, an intermediate fixing ring 2, and a vertical fixing rod 4, the vertical fixing rod 4 is multiple, and the outer sides of the multiple vertical fixing rods 4 are jointly sleeved with a pile head fixing ring 1 and multiple intermediate fixing rings 2, the pile head fixing ring 1 is located at the upper part of the vertical fixing rod 4, and the multiple intermediate fixing rings 2 are all located at the vertical fixing rod 4 below the pile head fixing ring 1, and the vertical fixing rod 4 is detachably installed with the pile head fixing ring 1 and the intermediate fixing ring 2 respectively;

[0033] A plurality of water pipes 3 are also provided on the inner side of the main frame. The upper part of each water pipe 3 is externally connected to a high-pressure water pump, and the lower part of each water pipe 3 is detachably provided with a high-pressure nozzle 5;

[0034] A plurality of first nuts 8 are fixed on the upper side of the pile head fixing ring 1, and the first nuts 8 are all threadedly mounted with first bolts 9;

[0035] A plurality of water pipe fixing rings 7 are installed on the inner ring surface of each intermediate fixing ring 2, and the water pipe 3 is fixed to the inner ring of the fixing ring 2 through the water pipe fixing rings 7.

[0036] A wireless inclinometer 14 is installed on the side surface of the vertical fixing rod 4.

[0037] Furthermore, a plurality of second nuts 11 are fixed to the upper sides of the pile head fixing ring 1 and the intermediate fixing rings 2, and third nuts 12 are fixed to the side surface of the vertical fixing rod 4 at positions corresponding to the pile head fixing ring 1 and the intermediate fixing rings 2. Second bolts 13 are commonly installed on the second nuts 11 and the third nuts 12 on the same side.

[0038] Furthermore, a plurality of pulleys 6 are installed on the outer ring surface of each intermediate fixing ring 2, and the pulleys 6 are in sliding contact with the inner surface of the steel pipe pile.

[0039] A support frame 10 is fixed to the center of the pile head fixing ring 1.

[0040] The working principle of the present invention is as follows:

[0041] After the present invention is assembled, it can be directly placed and fixed inside the steel pipe pile as shown. When placed inside the steel pipe pile, the pulleys 6 guide the entire device, reducing the friction force and making the placement process smoother. After being placed, the first nut 8 installed on the pile head fixing ring 1 and the first bolt 9 cooperating with the first nut 8 can be used. When the first bolt 9 is screwed, it is controlled to abut against the inner wall of the steel pipe pile, thereby fixing the device inside the steel pipe pile. Figure 7 The high-pressure nozzle 5 is connected to the water pipe 3, and the water pipe 3 is connected to a high-pressure water pump. The high-pressure water flow is used to make a pilot hole, facilitating the driving operation of the steel pipe pile.

[0042] The steel sheet pile can be erected at the designated position according to the on-site positioning. The wireless inclinometer 14 is turned on, the verticality is adjusted to meet the requirements, the high-pressure water pump is started, and the driving operation of the steel pipe pile is carried out. During the operation process, the wireless inclinometer 14 measures the inclination in real time. After the steel pipe pile driving is completed, the first bolt 9 is loosened, thereby disconnecting the connection between the pile head fixing ring 1 and the steel pipe pile. By using the equipment for driving the steel pipe pile and cooperating with the support frame 10, the present device can be pulled out. By repeating the above steps, the driving construction of the steel pipe pile can be completed.

[0043]

[0044] ​Among them, the diameters of the pile head fixing ring 1 and the middle fixing ring 2 are designed in multiple models and can be replaced according to the on-site needs during the flanging construction process, so as to adapt to steel sheet piles with different pile diameters. The outer diameters of the pile head fixing ring 1 and the middle fixing ring 2 need to be slightly smaller than the inner diameter of the steel pipe pile. In addition, the high-pressure nozzle 5 can also be replaced with different models. By replacing the high-pressure nozzle 5 and adjusting the water pressure and water flow rate, the soil in the hole can be loosened under different geological conditions, expanding the scope of use, so as to be applicable to different geological conditions.
