Description

Technical Field

[0001] This utility model relates to the field of foundation engineering equipment technology, and in particular to a combined hammer for a track-following wedge-shaped granular material pile driver. Background Technology

[0002] Loose material piles, being made of loose materials, do not solidify and will disperse in all directions after reaching a certain bearing capacity, unlike concrete piles or wooden piles which are self-contained. The single pile bearing capacity of loose material piles (i.e., the maximum load that a single pile can withstand under load, ensuring the strength and stability of the foundation soil and the pile itself, and that deformation is within the allowable range to guarantee the normal use of the structure) is mainly determined by the lateral constraint force of the soil around the pile. If the soil between the piles is loose, weak, and has low strength, and is not properly reinforced, the single pile bearing capacity will be very small, resulting in a significant waste of resources. We now use a construction method for wedge-shaped composite loose material piles, which involves first shaping the soil and rock retaining wall, and then constructing a wedge-shaped composite loose material pile layer by layer, consisting of a lower pile, a middle pile, a wedge-shaped upper pile, and a top enlarged diameter pile. Different piles have different construction requirements, and existing construction equipment cannot meet the construction requirements of wedge-shaped composite loose material piles.

[0003] Meanwhile, the following situations may arise during construction: During pile driving, the hammer breaks up rocks in the soil, using impact force to push the pulverized rocks to the side of the pile, forming a soil-rock retaining wall. However, if it encounters tilted rocks in a special location, repeated impacts may fail to break them, causing the hammer to deviate. Since the lugs at the top of the hammer are connected to the guide rail and are relatively fixed, this can cause the hammer and handle to separate, or deform and damage the guide rail device (including the rail), requiring additional time for re-hanging the hammer and repairing it, thus affecting efficiency. Secondly, if the hammer is tilted and has already entered the soil, the upward pulling force of the hammer is significantly weakened under the clamping effect of the crushed stone and soil, potentially causing equipment damage, further increasing maintenance costs and delaying the construction period.

[0004] In view of this, we propose a combined hammer for a track-following wedge-shaped granular material pile driver. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a combined hammer for a track-guided wedge-shaped granular material pile driver.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A combined hammer for pile drivers using wedge-shaped granular materials with a guide rail, characterized in that it consists of a gooseneck-shaped bar hammer with a guide rail, a flat conical long-necked center hammer, and a flat conical flat hammer.

[0008] The top of the gooseneck-shaped bar hammer is equipped with a hanging head. The hanging head connects the small bar hammer tube and the large bar hammer tube in the gooseneck-shaped bar hammer through the gooseneck connecting section using a universal micro-expansion hole connecting mechanism. The bottom of the gooseneck-shaped bar hammer is equipped with a stone breaking mechanism.

[0009] The top of the flat conical long-necked hammer is provided with a hanging head, which is connected to the hammer body of the flat conical hammer through the long-necked hammer handle;

[0010] The flat conical hammer is generally flat and round in shape, which is used to achieve the compaction of the upper wedge-shaped pile body, the shaping of the top wedge-shaped expanded diameter pile body, and the integration of the pile body with the retaining wall into the pile body.

[0011] Preferably, the bottom of the small hammer tube is provided with a large hammer tube, and the bottom of the large hammer tube is connected to the main rod section to obtain the rigid-flexible conversion effect of the hammer body.

[0012] Preferably, the bottom of the main rod section is connected to one or more adjustment sections to adjust the hammer weight and hammer height, and to facilitate connection with different types of hammer heads. The bottom of the adjustment section is connected to a connecting hammer head section, which is used to connect to the stone breaking mechanism.

[0013] Preferably, the flat conical hammer has a hanging head at the top and anti-clogging vent holes in the middle and at the bottom.

[0014] Preferably, the number of gooseneck connecting segments is one or more.

[0015] Preferably, the rock-breaking mechanism includes a base.

[0016] Preferably, one or more conical hammerheads are mounted on the base.

[0017] Preferably, the base is provided with a conical handle at the top, the conical handle is inserted into the bottom of the gooseneck-shaped hammer along the rail, the conical handle and the gooseneck-shaped hammer along the rail are connected by a horizontal pin, the two ends of the horizontal pin are provided with locking pins, and the conical handle (503) is provided with a conical sleeve around its periphery.

[0018] Preferably, the universal micro-expansion hole connection mechanism includes an upper seat, a lower seat, and a main rod. One end of the main rod is connected to the lower seat via a connecting shaft and a clamping plate. The other end of the main rod is connected to the upper seat via a main pin and an auxiliary pin. The upper seat is further fixed by a reinforcing plate around the main rod.

[0019] Preferably, the upper seat is fixedly connected to the hanging head or the gooseneck connecting section, and the lower seat is fixedly connected to the gooseneck connecting section or the small hammer tube.

[0020] Beneficial effects:

[0021] 1. The gooseneck-shaped hammer, driven by a guide rail, tamps the soil from top to bottom. The downward impact of the gooseneck-shaped hammer breaks up stones, which in turn compress the soil laterally. The soil and gravel become increasingly compacted due to this compression, forming a complete and solid protective wall for the pile hole. The flat-cone long-necked hammer continuously tamps the replacement material inside the pile hole, making it a unified whole under the constraint of the soil and rock protective wall. Finally, the flat-cone flat hammer continues to tamp and compact the soil, forming a top wedge-shaped expanded diameter pile. This makes the soil and rock protective wall, the lower pile, the middle pile, the upper wedge-shaped pile, and the top expanded diameter pile a unified whole, ensuring stability and reliability.

[0022] 2. By connecting the gooseneck connecting section with the small hammer tube of the hanging head and the gooseneck hammer in the rail, the "universal micro-expansion connection mechanism" achieves a flexible connection between the hammer body and the pile driver (track). This allows the upper end of the rail hammer to naturally oscillate to a certain extent (back and forth or left and right) during drilling operations, especially when the hammer bottom touches a large-diameter stone or hard object. By making good use of this micro-oscillation, it can not only eliminate the adverse factors caused by the rigid connection between the original pile driver track and the rail hammer (causing hard collision with the pile driver track and corresponding twisting and damage), but also achieve a certain degree of micro-expansion effect of gradually increasing the size of the pile hole from bottom to top.

[0023] 3. By setting a rock-breaking mechanism at the bottom of the gooseneck-shaped hammer, different shapes of conical hammers can be installed according to actual needs to meet the construction requirements of different sites. When encountering large sloping or side-standing rocks that are difficult to break with a single conical hammer, one conical hammer can be used to break the rock first, and the others can follow up. This can help to deal with the impact of the tilted hammer caused by large sloping rocks. This not only solves the problem of large sloping rocks that are difficult to break, but also greatly reduces the frequency of machine failure and improves construction efficiency.

[0024] 4. The bottom rock-breaking mechanism is connected to the bottom of the gooseneck-shaped hammer by the cone handle at the top of the base for quick disassembly, which greatly improves construction efficiency. Attached Figure Description

Detailed Implementation

[0037] The specific embodiments of this utility model are further described below. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] This application should provide a general but clear description of the core technical problem it aims to solve, the technical solution used to solve the core technical problem, and the technical effects that can be achieved.

[0039] like Figure 1-11 As shown, the present invention provides a combined hammer for a pile driver with a wedge-shaped loose material, which consists of a gooseneck-shaped bar hammer 1, a flat conical long-necked middle hammer 2, and a flat conical flat hammer 3.

[0040] The top of the gooseneck-shaped hammer 1 is provided with a hanging head 4. The hanging head 4 connects the small hammer tube 103 and the large hammer tube 102 in the gooseneck-shaped hammer 1 through the gooseneck connecting section 104 and the universal micro-expansion hole connecting mechanism 105.

[0041] It is worth further explaining that the jack 5 is used for lateral connection with the pile driver track.

[0042] In this embodiment, a large hammer tube 102 is provided at the bottom of the small hammer tube 103.

[0043] In this embodiment, the bottom of the large hammer tube 102 is connected to the main rod section 101.

[0044] In this embodiment, the bottom of the main rod section 101 is connected to one or more adjustment sections 106 to adjust the hammer weight and hammer height, and to facilitate connection with different types of hammer heads. The bottom of the adjustment section 106 is connected to the connecting hammer head section 107, which is used to connect the stone breaking mechanism 5.

[0045] It is worth noting that the small hammer tube 103, the large hammer tube 102, the main rod section 101, and the adjusting section 106 are all connected by welding, and are further fixed by reinforcing ribs on the sides.

[0046] It is worth further explaining that, depending on the construction needs, an adjustment section 106 can be added to increase the length of the gooseneck-shaped hammer 1 along the rail, and conversely, to reduce the length of the gooseneck-shaped hammer 1 along the rail.

[0047] In this embodiment, the universal micro-expansion hole connection mechanism 105 includes an upper seat 1051, a lower seat 1052, and a main rod 1053. One end of the main rod 1053 is connected to the lower seat 1052 via a connecting shaft 1054 and a clamping plate 1055. The other end of the main rod 1053 is connected to the upper seat 1051 via a main pin 1056 and an auxiliary pin 1057. The upper seat 1051 is further fixed by a reinforcing plate 1058 around the main rod 1053.

[0048] It is worth further explaining that the overlapping part of the lower end of the main rod 1053 and the lower seat 1052 is connected by a connecting shaft 1054, and then the two sections of the connecting shaft 1054 are fixed to the main rod 1053 and the lower seat 1052 respectively by using a clamping plate 1055 and bolts, so that the lower seat 1052 can swing and realize the universal joint function.

[0049] In this embodiment, the upper seat 1051 is fixedly connected to the hanging head 4 or the gooseneck connecting section 104, and the lower seat 1052 is fixedly connected to the gooseneck connecting section 104 or the small hammer tube 103.

[0050] In this embodiment, the number of gooseneck connecting segments 104 is one or more.

[0051] like Figure 3 As shown:

[0052] The top of the flat conical long-necked hammer 2 is provided with a hanging head 4, which is connected to the hammer body 202 of the flat conical hammer through the long-necked hammer handle 201.

[0053] It is worth further explaining that the flat cone-shaped long neck hammer 2 is used to continue backfilling and replacement material in the pile hole after the lower and middle pile bodies are formed, and then replace the flat cone-shaped long neck hammer 2 to continuously ram the pile. Through the transmission of ramming force, the middle and lower wedge-shaped pile bodies are further rammed and compacted and expanded at the same time, while also forming the upper wedge-shaped pile body with a larger upper part and a smaller lower part.

[0054] like Figure 4 As shown:

[0055] The flat cone-shaped hammer 3 has a hanging head 4 at the top.

[0056] The flat cone-shaped hammer 3 is generally flat and round in shape, which is used to achieve the compaction of the upper wedge-shaped pile body, the shaping of the top wedge-shaped expanded diameter pile body, and the integration of the pile body and the retaining wall into a single pile body.

[0057] It is worth further explaining that the flat cone-shaped hammer 3 continuously tamps the outer mold and the inner mold of the wedge-shaped pile body that has been backfilled with replacement material. After reaching the hammer stop standard, the tamping is stopped, forming a wedge-shaped pile body with the replacement material gradually expanding from bottom to top. At the same time, the outer mold (tamping pit) at the top of the pile body is formed, and the replacement material is filled into the outer mold at the top of the pile body and tamped densely with the flat cone-shaped hammer to form a top wedge-shaped pile body with expanded diameter.

[0058] It is worth noting that the flat conical hammer 3 has anti-clogging vent holes in the middle and at the bottom.

[0059] like Figure 2 , 5 As shown:

[0060] The bottom of the gooseneck-shaped rock hammer 1 is equipped with a rock-breaking mechanism 5.

[0061] In this embodiment, the rock-breaking mechanism 5 includes a base 501.

[0062] In this embodiment, one or more conical hammerheads 502 are mounted on the base 501.

[0063] It is worth further explaining that when performing individual extrusion and impact operations, a conical hammer 502 is installed on the base 501 using bolts, which can quickly break and crush stones during construction and accelerate the drilling operation.

[0064] It is worth further explaining that when encountering rocks that are difficult to break with a single conical hammer, multiple conical hammers 502 can be installed on the base 501 by bolts or welding, so that one hammer breaks the rock first, and the others follow. This can help to deal with the impact of the tilted hammer caused by large rocks on the slope. This not only solves the problem of large rocks on the slope that are difficult to break, but also significantly reduces the frequency of machine failures such as the tilted hammer colliding with the guide rail device, thus improving construction efficiency.

[0065] It is worth noting that, when construction requires it, the rock-breaking mechanism 5 can be removed and converted into a pile compaction mechanism.

[0066] like Figure 6 As shown:

[0067] Once the rock breaking and squeezing are completed and the pile hole meets the design requirements, the hammer head is quickly disassembled to form a "flat-headed" tamping hammer head (hammer body). To achieve rapid disassembly, the connection between the hammer head and the hammer body adopts a "pin-type connection device" to improve construction efficiency.

[0068] like Figure 7 , Figure 10 As shown:

[0069] It is worth further explaining that the "universal joint" achieves a flexible connection, forming a "gooseneck" function. During the driving process, especially when the hammer bottom touches large-diameter stones or hard objects, the upper end of the gooseneck hammer 1 will naturally produce a certain degree of (back-to-back or left-to-right) slight oscillation. The "universal joint" function leaves a certain amount of room for this oscillation, forming a gooseneck function and achieving a flexible connection effect. This not only eliminates the adverse factors caused by the rigid connection between the original pile driver track and the gooseneck hammer (causing hard collisions with the pile driver track and corresponding twisting and damage), but also achieves a certain degree of micro-expansion effect of gradually increasing the hole size from bottom to top.

[0070] like Figure 8 As shown:

[0071] In this embodiment, the top of the base 501 is provided with a tapered handle 503, which is engaged with the horizontal pin 504 in the bottom groove of the gooseneck-shaped hammer 1. It is further fixed by the pins 505 on both sides. The tapered handle 503 is provided with a tapered sleeve 506 around its periphery.

[0072] It is worth further explaining that the bottom of the gooseneck-shaped hammer 1 has a groove, in which a horizontal pin 504 is horizontally placed. The cone shank 503, which is fixedly connected to the top of the base 501, can be inserted into the center of the horizontal pin 504. The horizontal pin 504 and the cone shank 503 are engaged, and then further secured by the pins 505 on both sides of the horizontal pin 504, thus connecting the rock-breaking mechanism 5 with the gooseneck-shaped hammer 1. The rock-breaking mechanism 5 can be disassembled by removing the cone shank 503 from the horizontal pin 504, and the appropriate cone head can be replaced at any time according to different geological needs. This mechanism enables rapid disassembly and can be adapted to different construction requirements, greatly improving construction efficiency.

[0073] like Figure 9 As shown:

[0074] In this embodiment, the construction of wedge-shaped composite granular material piles was completed by sequentially using a gooseneck-shaped hammer 1, a flat-conical long-necked hammer 2, and a flat-conical flat hammer 3. The process involves first shaping the wedge-shaped pile hole for the soil-rock retaining wall, then constructing the wedge-shaped composite granular material pile body layer by layer, consisting of a lower pile body, a middle pile body, an upper wedge-shaped pile body, and a top-expanded pile body. Different pile bodies have different construction requirements to meet the overall construction needs of the wedge-shaped composite granular material pile body.

[0075] The gooseneck-shaped hammer 1, driven by a guide rail, tamps the soil from top to bottom. The downward impact of the gooseneck-shaped hammer 1 breaks up the rocks, which in turn squeeze the soil laterally. The soil and gravel become increasingly compacted due to this compression, forming a complete and solid protective wall for the pile hole. The flat-cone long-neck-shaped hammer 2 continuously tamps the replacement material inside the pile hole, making it a unified whole under the constraint of the soil and rock protective wall. Finally, the flat-cone flat hammer 3 continues to tamp and compact the soil, forming a top wedge-shaped expanded diameter pile body. This makes the soil and rock protective wall, the lower pile body, the middle pile body, the upper wedge-shaped pile body, and the top expanded diameter pile body a unified whole, ensuring stability and reliability.

[0076] like Figure 11 As shown, during the construction process:

[0077] S1. Stop the construction equipment in the construction area and align the gooseneck hammer 1 of the pile driver with the pile position to prepare for pile driving.

[0078] S2. Micro-expansion: The gooseneck hammer 1, mounted on the track, tamps the soil from top to bottom. The downward impact of the gooseneck hammer 1 breaks up stones, and the broken stones squeeze the soil laterally. The soil and gravel become increasingly compacted due to the compression, thus forming a complete and solid protective wall for the pile hole. At the same time, due to the lateral connection between the top of the gooseneck hammer 1 and the pile driver track, a flexible connection is achieved through the universal micro-expansion connection mechanism 105, forming a "gooseneck" function. During the driving process, especially when the bottom of the hammer touches large-diameter stones or hard objects, the upper part of the gooseneck hammer 1 will naturally produce a certain degree of (back-to-back or left-to-right) micro-oscillation. The "universal joint" function leaves a certain amount of room for this oscillation, forming a flexible connection effect. This not only eliminates the adverse factors caused by the rigid connection between the original pile driver track and the gooseneck hammer (causing hard collisions with the pile driver track and corresponding twisting and damage), but also achieves a certain degree of micro-expansion effect for the pile hole from bottom to top, forming a complete and continuous wedge-shaped pile hole.

[0079] S3. Lower Pile Construction: After the pile hole and stable retaining wall are formed, replacement material is filled in sections from bottom to top. At the same time, the hammer head is changed to carry out section tamping to ensure that each section of the lower pile body achieves vertical compaction and lateral compression of the hole wall, so that the pile body and the retaining wall form a vertical bearing body that is tightly bonded. At the same time, a wedge-shaped lower pile body with a diameter that gradually increases from bottom to top is formed.

[0080] S4. Middle Pile Construction: Replacement material is filled into the pile hole in sections from bottom to top, and ramming is carried out in sections to ensure that each section of the middle pile body achieves vertical compaction and lateral compression of the hole wall, so that the pile body and the retaining wall form a vertical bearing body that is tightly bonded; at the same time, a wedge-shaped replacement material middle pile body with a diameter that gradually increases from bottom to top is formed.

[0081] S5. Upper pile body molding: After the lower and middle pile bodies are formed, continue to backfill the replacement material in the pile hole, and then replace the flat cone long neck 2 hammer to continuously ram the pile. Through the transmission of ramming force, the middle and lower wedge-shaped pile bodies are further rammed and compacted and expanded at the same time, and the upper wedge-shaped pile body outer mold is also formed.

[0082] S6. Upper pile body formation: The inner cavity of the wedge-shaped pile body formed under the S5 operation is filled with replacement material; a flat cone-shaped hammer 3 is used to continuously ram the wedge-shaped pile body with replacement material backfilled in S5 and the replacement material inside the mold. After the hammer is stopped when the hammer is stopped, the upper wedge-shaped pile body with replacement material gradually expands from bottom to top, and at the same time, the outer mold (ramming pit) at the top of the pile body is formed.

[0083] S7. Pile top formation: Fill the outer mold at the top of the pile body with replacement material and continue to compact it with a flat cone hammer 3 to form a wedge-shaped expanded diameter pile body at the top.

[0084] S8. Wedge-shaped composite granular material piles are constructed through the above steps to form a complete and continuous wedge-shaped composite granular material pile body. Multiple piles of different diameters and shapes are superimposed on the same vertical line, with the diameter gradually increasing from bottom to top. The pile body and the retaining wall are tightly integrated into one.

[0085] The embodiments of this utility model have been described in detail above, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
