On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0027] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is said to be "directly on" another element, there are no intermediate elements.

[0028] Implementation method 1:

[0029] Reference Figures 1 to 3 A pile driving counterweight structure includes a base 100, a water bag 200 and a water pump 300; the base 100 is provided with a pile driver fixing portion 150 for installing a pile driver 600, the base 100 is provided with a counterweight position 160, and the water bag 200 is placed on the counterweight position 160; the water bag 200 is provided with a drain port 210, and the water pump 300 is detachably connected to the drain port 210, and the water pump 300 can inject water into and drain water from the water bag 200.

[0030] The base 100 is provided with a counterweight position 160 and a pile driver fixing part 150 for installing the pile driver 600. When the pile driver counterweight structure of this embodiment is used to perform pile driving, the pile driver 600 is fixed on the pile driver fixing part 150, the water bag 200 is placed on the counterweight position 160, the water pump 300 is connected to the drain port 210 of the water bag 200, and the water pump 300 is used to inject water into the water bag 200 to reach a predetermined water volume. At this time, the reaction force of the pile driver 600 during pile driving is mainly provided by the deadweight of the water bag 200 filled with water, the deadweight of the pile driver 600 and the deadweight of the base 100, thereby completing pile driving. After the pile driving is completed, the water in the water bag 200 is pumped into the water bag 200 of another pile driving position by the water pump 300 using the flow characteristics of water.

[0031] Therefore, the pile-pressing counterweight structure of this embodiment has the following advantages over the prior art:

[0032] (1) The water bag 200 itself is light in weight and very convenient to carry. No special transportation is required. Water can be taken on site, which greatly saves transportation costs. It is particularly suitable for projects with small pile driving engineering quantities, and of course it is also suitable for projects with large engineering quantities. (2) During the construction process, the water pump 300 and water pipe can be used by the flowing nature of water, and no hoisting is required. Therefore, the pile driving counterweight structure and pile driving device of this embodiment also have the advantages of flexible and convenient use. It is not only suitable for pile driving in large sites, but also suitable for pile driving in narrow sites, which greatly reduces construction costs, improves construction speed, and has high working efficiency. (3) The shape of the water bag 200 filled with water counterweight can be flexibly arranged according to the characteristics of pile driving, which can solve the problem of side piles, corner piles and obstacles that cannot be constructed. (4) The water bag 200 has a low cost and can be used multiple times. It has obvious economic advantages over traditional counterweight block pile driving.

[0033] Specifically, the base 100 includes a base main beam 110 and a base cross beam 100, two base main beams 110 are provided, the base cross beam 100 is connected between the base main beams 110, the pile driver fixing part 150 is provided on the base cross beam 100, and the counterweight 160 is provided on the base main beam 110. Preferably, the base main beams 110 are arranged parallel to each other, the base cross beam 100 is arranged perpendicular to the base main beam 110, and the base cross beam 100 is provided with a threaded hole for installing and fixing the pile driver 600, so that the pile driver 600 can be installed and fixed on the base cross beam 100 by fasteners such as bolts and nuts.

[0034] Preferably, refer to Figures 1 to 3 The base 100 further includes a bottom plate 130, which is laid horizontally on the base main beam 110, and the water bag 200 is placed on the bottom plate 130. On the one hand, the deadweight of the bottom plate 130 can also provide a reaction force for the pile driver 600 when pressing the pile, and on the other hand, the bottom plate 130 can ensure the smoothness of the water bag 200 when it is filled with water and maintain the shape of the water bag 200 itself, and can be carried out according to a predetermined water volume. Moreover, the setting of the bottom plate 130 can also ensure that the water bag 200 is located on the base 100 and does not touch the ground, so that the water bag 200 filled with water can provide a predetermined reaction force for pile pressing.

[0035] The predetermined water volume of the water bag 200 can be calculated by reverse calculation based on the reaction force required for pile driving. For example, the predetermined water volume of the water bag 200 can be calculated by subtracting the required weight of the pile driver 600, the base 100, the bottom plate 130, etc.

[0036] Better, refer to Figures 1 to 3 The pile-pressing counterweight structure also includes a water meter 400. The water meter 400 is preferably an intelligent water meter 400 that can be flexibly reset to zero. By connecting the water meter 400 to the water pump 300, the water injection amount or water output of the water bag 200 can be easily known.

[0037] Preferably, refer to Figure 1 The base 100 further includes a plurality of connecting cross bars 140, and the connecting cross bars 140 are connected between the base main beams 110. The connecting cross bars 140 can enhance the structural strength of the entire base 100, thereby being able to withstand a larger weight of the water bag 200.

[0038] Better, refer to Figure 1The pile-pressing counterweight structure also includes a sub-base 500, which includes an extended main beam 510 and a sub-connecting crossbar 520. The extended main beam 510 corresponds to the base main beam 110 one by one, and the sub-connecting crossbar 520 is connected between the extended main beams 510; the ends of the base main beams 110 are detachably connected to the corresponding extended main beams 510. When the sub-base 500 is set, the base main beam 110 does not need to be too long, and the sub-base 500 can be directly spliced ​​with the base 100 on site, which is convenient for transportation, and sub-bases 500 of different lengths can be spliced ​​according to the actual situation on site or multiple sub-bases 500 can be spliced, which is more flexible and convenient as a whole and has strong applicability.

[0039] Specifically, refer to Figures 1 to 3 The base cross beam 100 is connected to the middle of the base main beam 110, the connecting cross bar 140 is connected between the base main beams 110 and located on both sides of the base cross beam 100, and the bottom plate 130 is laid horizontally on both sides of the base cross beam 100. Preferably, the bottom plate 130 is suitable for being laid horizontally on the base main beam 110 in the center, and the two ends of the bottom plate 130 extend symmetrically from the base main beam 110, so that it is more stable when piling.

[0040] In addition, refer to Figure 1 and Figure 3 This embodiment further provides a pile driving device, which includes a pile driving machine 600 and the above-mentioned pile driving counterweight structure. The pile driving machine 600 is detachably mounted on the pile driver fixing part 150 of the pile driving counterweight structure by bolts.

[0041] When using the pile driving device to drive piles, assemble the base 100, set the base 100 at the pile driving position, install and fix the pile driver 600 on the pile driver fixing part 150, and the size of the base 100 should be determined comprehensively in combination with the pile driving reaction force, the size of the selected water bag, the surrounding environment, etc., lay the bottom plate 130, and place the water bag 200 on the floor, and use the water pump 300 to inject water into the water bag 200 to reach a predetermined water volume, then start the pile driver 600 to drive piles, assemble another base while driving piles, set the base at the second pile driving position, repeat the operations of installing the pile driver, laying the bottom plate and placing the water bag, and after the first pile driving is completed, pump the water in the water bag at the first pile driving position into another water bag through the water pump, so that the water in the water bag can be recycled to carry out the pile driving operation at the second pile driving position.

[0042] Implementation Method 2

[0043] Reference Figure 4 and Figure 5, which is different from the first embodiment in that: the base 100 includes a base sub-beam 170, the base sub-beam 170 is arranged in the same direction as the base main beam 110, one end of the bottom plate 130 is arranged on the base main beam 110, and the other end of the bottom plate 130 is arranged on the base sub-beam 170. For the pile pressing construction such as side piles or corner piles that are more affected by the construction space, this embodiment can extend the counterweight position 160 to the direction with space by setting the base sub-beam 170, so as to facilitate the placement of the water bag 200.

[0044] Implementation Method 3

[0045] Reference Figure 6 and Figure 7 , which is different from the first embodiment in that: the base 100 of the third embodiment does not use the structure of the base main beam and the base cross beam, and the base 100 directly uses the raft 101, that is, a cast-in-place reinforced concrete slab, and the thickness of the raft 101 is relatively thick. According to the designed pile-pressing position, a pile-pressing hole 1010 is opened on the raft 101, and the pile driver fixing part 150 is arranged around the pile-pressing hole 1010, and the water bag 200 is placed on the raft 101. The pile driver fixing part 150 preferably adopts the method of opening a deep bolt hole. When the pile driver is used for pile-pressing operation, the pile driver is fixed to the raft 101 by bolts. Because the thickness of the raft 101 is thick and the structural strength is stable, the reaction force of the pile driver during pile-pressing will not destroy the structure of the raft 101. At the same time, by placing the water bag 200 on the raft 101, the water bag 200 and the raft 101 provide reaction force for the pile-pressing operation, ensuring that the pile is pressed to a sufficient depth. This embodiment is suitable for occasions where the raft 101 needs to be cast on site, and the raft 101 structure is used for pile pressing. The water bags 200 are placed around the pile pressing holes 1010 where pile pressing is performed as much as possible. Of course, they can also be distributed on any part of the entire raft 101 except the pile pressing holes 1010 being operated. Building materials on site can also be piled on the raft 101 to provide a reaction force for pile pressing. Placing the water bags 200 on the raft 101 first has the advantage of a large enough position, which can hold enough water bags 200, and the placement of the water bags 200 is relatively flexible.

[0046] Implementation Method 4

[0047] Reference Figure 8 and Fig. 9, which is different from the first embodiment in that: the base 100 also includes an existing reinforced concrete slab 180, the base main beam 110 and the base cross beam 120 are both fixedly connected to the existing reinforced concrete slab 180 through threaded fasteners 700, the bottom plate 130 is transversely laid on the base main beam 110, and both ends of the bottom plate 130 are fixedly connected to the existing reinforced concrete slab 180 through threaded fasteners 700. This embodiment is suitable for the case where there is an existing reinforced concrete slab on site, but the structural thickness of the existing reinforced concrete slab 180 does not reach the thickness and structural strength of the cast-in-place raft slab 101 in the third embodiment, so by providing the base main beam 110 and the base cross beam 120, the bottom plate 130 is transversely laid on the base main beam 110, and the water bag 200 is placed on the bottom plate 130. This embodiment can not only utilize the structural strength of the existing reinforced concrete slab 180 to provide a reaction force for the pile driver 600 during operation, but also enhance the structural strength of the entire base 100 structure through the base main beam 110 and the base cross beam 120, and the pile driver fixing part is arranged on the base cross beam 120. The configuration of the water bag 200 can further provide the reaction force required for pile driving, and the entire pile driving counterweight structure can provide a greater reaction force for the pile driving operation, ensuring that the pile driving operation can be driven to a sufficient depth. The threaded fastener 700 is preferably an expansion screw, which can be firmly connected to the existing reinforced concrete slab 180 and is easy to disassemble.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
