[0002] Hammer pile driving utilizes the instantaneous impact mechanical energy of the pile hammer when it falls to overcome the resistance of the soil to the pile, destroying its static equilibrium state, causing the pile body to sink and reach a new static pressure equilibrium state. By repeatedly hammering the pile head, the pile body will continue to sink. Hammer pile driving is the most commonly used pile driving method for precast piles. This method has a fast construction speed, a high degree of mechanization, a wide range of adaptability, and a high level of on-site civilization. The machinery and equipment used for piling mainly include three parts: a pile hammer, a pile frame, and a power unit.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-7 As shown, a pile driving and replacement device for various diameters includes a hydraulic hammer 1, a hydraulic hammer anvil cap 2 and a docking pile assembly; the lower end of the hydraulic hammer 1 is connected to the hydraulic hammer anvil cap 2, and the inner wall of the hydraulic hammer anvil cap 2 is connected to the docking pile assembly, which is used for docking piles of various diameters.

[0023] like Figure 1 、 2 As shown, the docking pile assembly includes a plurality of first opening guide plates 3 , and the plurality of first opening guide plates 3 are evenly connected to the inner wall of the hydraulic hammer anvil cap 2 .

[0024] Specifically, first, a hydraulic hammer 1 is connected to a hydraulic hammer anvil cap 2, and six first opening guide plates 3 are evenly welded inside the hydraulic hammer anvil cap 2. The spacing of the formed guide space is 50 mm larger than that of each side of the pre-sunk pile, so that the pile can normally enter the anvil cap space and drive a pile of the first pile diameter.

[0025] like Figure 3 、 4 As shown, each first hole guide plate 3 is connected to a second hole guide plate 5 via a plurality of bolts 4. There are six first hole guide plates 3, and the number of second hole guide plates 5 corresponds to the number of first hole guide plates 3.

[0026] Specifically, when it is necessary to drive piles of the second pile diameter, the second hole guide plate 5 is connected to the first hole guide plate 3 by bolts 4. Since the energy during the pile sinking process is relatively large, in order to prevent the bolts from falling off, it is necessary to weld and reinforce the nut side after the bolts 4 are connected to prevent loosening. Then the hydraulic hammer anvil cap 2 is inserted into the pile. The distance between the second hole guide plate 5 and the pile is the same as 50 mm, and piles of the second pile diameter are driven.

[0027] like Figure 5 、 6As shown in Figures 7 and 8, the hammer bushing 6 further includes a replacement bushing 6, the upper end of which is inserted into the interior of the hydraulic hammer anvil cap 2, and the outer wall of which contacts the plurality of first perforated guide plates 3. The replacement bushing 6 is connected to the hydraulic hammer anvil cap 2 via four sets of lifting lug assemblies, which are evenly distributed on the outer wall of the replacement bushing 6. The lifting lug assemblies include upper lifting lugs 7, lower lifting lugs 8, and a connecting chain 9. The upper lifting lugs 7 are connected to the lower end of the side wall of the hydraulic hammer anvil cap 2, and the lower lifting lugs 8 are connected to the lower end of the side wall of the replacement bushing 6. The upper lifting lugs 7 and the lower lifting lugs 8 are connected by a connecting chain 9.

[0028] Specifically, when the third type of pile needs to be driven, the welding side of the bolt 4 needs to be cut, the second perforated guide plate 5 needs to be removed, and then the replacement sleeve 6 needs to be inserted into the hydraulic hammer anvil cap 2, with the first perforated guide plate 3 and the replacement sleeve 6 spaced 50 mm apart. Then, the upper lifting lug 7 on the hydraulic hammer anvil cap 2 and the lower lifting lug 8 on the replacement sleeve 6 are connected with a connecting chain 9, with four upper lifting lugs 7 and four lower lifting lugs 8 each. Then, the lower end of the replacement sleeve 6 is inserted into the pile, with the insertion portion spaced 50 mm apart from the pile, to drive a pile of the third type of pile diameter. When driving piles of the third type of pile diameter, closely spaced piles with smaller pile spacing can be used, which are not affected by the pile spacing and can better adapt to the on-site pile sinking environment.

[0029] Through the above three methods, steel pipe piles with three different pile diameters can be sunk, saving construction vessels and hydraulic hammers and improving pile sinking construction efficiency.

[0030] The hydraulic hammer is set according to the pile diameter and pile spacing. There are three types of designs. The first hammer cap is used for Steel pipe pile, make a hammer cap with a height of 2 meters, and the inner extension distance of the hammer cap is inner diameter Sunken When using steel pipe piles, 6 first opening guide plates 3 are evenly distributed in the hammer cap. The first opening guide plates 3 are welded to the inner side of the hammer cap 2. 5 holes are opened on each first opening guide plate 3. When sinking piles, The pile is inserted into the hammer cap, and the distance between the pile and the first hole guide plate 3 is 50 mm.

[0031] The second hammer cap is in the original The pile is reconstructed on the basis of the second hole guide plate 5, and the first hole guide plate 3 is connected with the guide plate 3 with the same hole by bolts 4, and then the nut side is welded firmly to prevent it from falling during the pile sinking process. The pile is inserted into the hammer cap, and the distance between the pile and the second hole guide plate 5 is 50 mm.

[0032] The third hammer cap is in the original The pile is reconstructed on the basis of a 3580mm high replacement sleeve 6, with an upper outer diameter Lower outer diameter Insert the upper part of the replacement sleeve 6 into The hammer cap is inserted into the pile of 1900, and the replacement sleeve 6 and the hammer cap 2 are effectively connected by 4 chains. The inner diameter spacing of the piles is about 50mm. By inserting the replacement sleeve 6 into the pile, densely packed piles can be driven without being affected by the already driven piles, which can better ensure the construction quality. When the pile spacing is large, the hammer cap can be inserted into the pile tip. At the same time, the hammer cap is also convenient for the subsequent transition section to be installed inside the hammer cap. When the pile spacing is small, the distance between the piles that have been sunk and the pre-driven piles is less than the thickness of the hammer cap and the accessories on the hammer cap. At this time, it is more reasonable and convenient to insert the transition section into the pile for driving. It will not be affected by the already driven piles.

[0033] During the construction process, there will be three rows of piles being driven. The closely packed piles are located in the middle of the three rows and are shorter. The distance between the closely packed piles is very small, only 100mm. Generally, when the distance between the piles is large, the three types of piles can be driven by adjusting the inner guide plates (the first perforated guide plate 3 and the second perforated guide plate 5). However, the distance between the closely packed piles is only 100mm. The thickness of the pile hammer cap itself plus the outer lug plate exceeds 100mm, so it is necessary to add a replacement driving sleeve 6. Because the replacement driving sleeve 6 is inserted into the pile to achieve pile driving, it does not affect the adjacent piles.

[0034] The present invention relates to a device for driving and replacing piles of various pipe diameters. The device is constructed by evenly connecting a plurality of first opening guide plates 3 on the inner wall of a hydraulic hammer anvil cap 2, and connecting a second opening guide plate 5 to each first opening guide plate 3 via a plurality of bolts 4. The upper end of a replacement driving sleeve 6 is inserted into the interior of the hydraulic hammer anvil cap 2, and four sets of lifting ear assemblies are connected to the hydraulic hammer anvil cap 2. The device can complete the driving of steel pipe piles of three different pile diameters, save construction vessels and hydraulic hammers, and improve the efficiency of pile driving construction.
