Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction technology, in particular to a pile construction equipment and method. BACKGROUND

[0002] In the construction, in order to improve the bearing capacity of the foundation soil, it is usually necessary to use piles to reinforce or improve the foundation. Common piles include cast-in-place piles, precast piles and cement-soil composite piles. Among them, the cast-in-place pile is formed by using a pile equipment to drill a pile hole in the foundation soil on the construction site, then placing a reinforcement cage into the pile hole, and then pouring concrete to form the pile. The precast pile is preformed in the factory. Compared with the cast-in-place pile, it can save the operation time of pouring and waiting for the concrete to solidify on site. In the construction site, it only needs to use the pile equipment to send it into the foundation soil. It is common to use a power hammer to drive or press it into the foundation soil. The cement-soil composite pile is formed by first drilling a grout hole in the foundation soil using a pile equipment, and then sending a precast pile into the grout hole using a pile equipment to form a composite pile.

[0003] For the above-mentioned pile types, the current common pile equipment can be roughly divided into two categories. One is to drill a hole in the foundation soil, and the other is to send a pile into the foundation soil. That is, the pile equipment has the functions of drilling or sending piles. At present, most pile equipment only has a single drilling or pile sending function. The disadvantage of such pile equipment is particularly evident when performing cement-soil composite pile construction. Two different pile equipment are needed to drill holes and send piles, respectively, which is not conducive to the efficiency and cost of construction operations. Therefore, some manufacturers have proposed to equip the pile equipment with drilling and pile sending functions at the same time. However, most of these devices are simply stacked. There are still many shortcomings in actual use. For example, when the pile equipment can drill holes in the foundation soil, the drilling equipment is arranged at the end of the machine body platform, and the drilling operation point is designed outside the equipment, i.e. the drilling equipment is installed on the outside of the pile frame. In this way, one side of the entire pile equipment is heavier, resulting in an unbalanced weight distribution of the entire pile equipment. In order to avoid the overturning of such a large equipment due to its own weight imbalance, a counterweight needs to be installed on the opposite side of the pile frame to balance it, and a pull rod needs to be configured to support the end of the pile frame. In addition, the self-weight of the pile equipment also needs to be increased. After the above modifications, although the equipment can be prevented from overturning, the weight of the entire equipment will be doubled, which will increase the requirement for the soil quality of the bearing equipment. This requires the reinforcement of some soft soil foundations, which will significantly increase the construction cost.

[0004] The above is the deficiency of the prior art. SUMMARY

[0037] The pile construction equipment and method disclosed in the embodiments of the present application can complete drilling and piling simultaneously using one pile construction equipment, and the drilling and piling operation points are inside the equipment, so that drilling and piling inside the equipment can be realized, the risk of equipment overturning due to unbalanced weight can be reduced, and the operation efficiency of construction can be improved while improving the operation safety.

[0038] <Embodiment I>

[0039] The present embodiment provides a pile construction equipment, which comprises an equipment body, such as Figure 1 As shown in the figure, the equipment body comprises a walking mechanism 1, which can be used to move the equipment body, i.e. the entire pile construction equipment, to the position where operation is needed. Specifically, the walking mechanism 1 can adopt a walking type as shown in the figure, or can also adopt a track type, and can also adopt a car type, and the present embodiment does not make specific limitation thereon. Figure 1

[0040] The walking mechanism 1 is provided with a machine body 2, which can provide support or counterweight for a rack 3 installed thereon. The rack 3 is provided with a drilling track 32 and a piling track 31 for support. The drilling track 32 is provided with a drilling mechanism 5 which can move up and down on the ground to drill, and the piling track 31 is provided with a piling mechanism 4 which can move up and down to pile on the ground. In the present embodiment, at least one of the piling track 31 and the drilling track 32 is close to the center of the machine body 2, i.e. the piling track 31 is close to the center of the machine body 2, or the drilling track 32 is close to the center of the machine body 2, or both the piling track 31 and the drilling track 32 are close to the center of the machine body 2. The center of the machine body 2 herein refers to the center of the machine body 2 in the x, y axis direction as shown in the figure, which is referred to as the transverse direction in the present embodiment, and the y axis direction is referred to as the longitudinal direction, and the z axis direction is referred to as the vertical direction. Figure 1

[0041] ​​By designing at least one of the piling track 31 and the drilling track 32 near the center of the machine body 2, the ground work points of at least one of the piling mechanism 4 installed on the piling track 31 and the drilling mechanism 5 installed on the drilling track 32 can be formed within the coverage area of ​​this construction equipment. Here, the ground work point of the drilling mechanism 5 or the piling mechanism 4 within the coverage area of ​​the construction equipment refers to, with reference to... Figure 1 The working point refers to the operating position of the drilling mechanism 5 or the piling mechanism 4 on the construction site, located between the traveling mechanisms 1 on both sides of the equipment body, rather than outside the traveling mechanism 1 on one side. This allows at least part of the track to be closer to the center of the machine body 2 and away from the edge of the machine body 2, which improves the overall weight imbalance of the equipment body. Furthermore, drilling and piling within the equipment body allows the force application point during operation to be closer to the center of the machine body 2, improving and enhancing the stability of the equipment body. At the same time, it avoids the imbalance caused by drilling and piling on one side of the machine body 2 in traditional equipment, and the need to increase the overall weight by several times due to the need to increase the equipment's self-weight and counterweight to overcome the overturning caused by the imbalance, which leads to the high cost of reinforcing the soft soil foundation. Furthermore, the equipment in this embodiment is designed with both a piling track 31 and a drilling track 32. When piling is being carried out, the foundation soil has already been broken up by the drilling mechanism 5. When driving the pile, it can rely on the weight of the pile itself or only require a small piling force. Compared with static pressure pile equipment, it can avoid the trouble of relying solely on static pressure to press the pile into the foundation soil, where the foundation soil generates a large reaction force on the static pressure pile equipment, and the need to add a large weight counterweight to maintain the stability of the static pressure pile equipment.

[0042] The frame 3 adopts an integral frame structure and is installed near the center of the body 2. That is, the frame 3 is not installed on the edge of the body 2, but is closer to the center of the body 2. This avoids the whole equipment being unbalanced due to the frame 3 being installed on the edge of the body 2, and thus avoids the problem of the equipment tipping over due to unbalanced weight.

[0043] like Figure 2 As shown, the overall frame structure of the frame 3 includes a roughly rectangular outer frame 34 and an internal support rod assembly 35 installed in the internal space formed by the outer frame 34. This structural form, combining the outer frame 34 with the internal support rod assembly 35, improves the strength and stability of the frame 3 while reducing its weight, thereby improving the weight balance and overall strength of the equipment. Specifically, the outer frame 34 is formed by a combination of horizontal, vertical, and diagonal rods, and the internal support rod assembly 35 also includes horizontal, vertical, and diagonal rods.

[0044] The length of frame 3 is greater than the width of fuselage 2, that is, in Figure 1The size of the frame 3 is greater than that of the machine body 2 in the direction indicated by the Y axis. In this way, the length of the machine body 2 in the longitudinal direction is shortened relative to the frame 3, and a greater working space can be provided for the pile driving mechanism 4 and the drilling mechanism 5 mounted on the frame 3. To improve the firmness of the connection between the two, a clamping leg 22 is designed, which can be designed to have an inner connecting body structure extending into the interior of the machine body 2, i.e., the frame 3 is connected and reinforced with the machine body 2 by being inserted into the machine body 2. Alternatively, the clamping leg 22 can be designed to have a side connecting body structure connected to the side of the machine body 2, in which case the clamping leg 22 is generally triangular, one side of which is connected to the side of the machine body 2 to form a side connecting body, and the other side is connected to the bottom of the frame 3, thereby completing the connection and reinforcement of the frame 3 with the machine body 2. Alternatively, the clamping leg 22 has both an inner connecting body extending into the interior of the machine body 2 and a side connecting body connected to the side of the machine body 2.

[0045] Of course, in other embodiments, the length of the frame 3 can also be equal to the width of the machine body 2, in which case only the working hole 21 needs to be designed at the corresponding pile driving and drilling positions of the machine body 2. In the present embodiment, the working hole 21 is also designed on the machine body 2 to increase the range of application of the pile spacing in different working scenarios, and the working hole 21 penetrates the machine body 2 in the vertical direction and is adapted to the larger size of the drill rod of the drilling mechanism 5 and the pile in the pile driving mechanism 4, thereby facilitating the passage of the drill rod or the pile through the working hole 21 downward.

[0046] In the present embodiment, the power device 6 for providing driving force for the drilling mechanism 5 and the pile driving mechanism 4 is installed on the top of the frame 3, and the vertical height of the drilling track 32 and the pile driving track 31 is designed to be higher than the height of the frame 3, thereby lowering the center of gravity of the frame 3 as a whole, reducing the influence of the high center of gravity on the easy overturning, and improving the stability of the entire device. The specific power device 6 can be selected from common winches and the like, and a pulley block and a steel wire rope are used to drive the pile driving mechanism 4 and the drilling mechanism 5 to move up and down for pile driving and drilling, which is not specifically limited in the present embodiment.

[0047] In other variants of the present embodiment, the frame 3 can adopt a pull rod type structure as shown in Figure 4 the example, in which an inclined pull rod 36 is provided to support the drilling track 32 and the pile driving track 31. Alternatively, the frame 3 can adopt a combined structure as shown in Figure 5 the example, which includes a box type base 37 and an inclined pull rod 36 mounted on the box type base 37, wherein the inclined pull rod 36 is connected to the drilling track 32 and the pile driving track 31, and the box type base 37 is mounted on the machine body 2. Of course, it can be understood that the above structures are only exemplary illustrations of the structure of the frame 3 and are not limiting.

[0048] To improve operational efficiency, the drilling track 32 and the piling track 31 are longitudinally spaced on the frame 3, as explained above. In this embodiment, longitudinal refers to... Figure 1 In the example, the y-axis direction refers to the vertical direction, the z-axis direction, and the x-axis direction. Furthermore, the longitudinal spacing between the drilling track 32 and the piling track 31 is a positive integer multiple of the spacing between unit pile positions. The spacing between unit pile positions refers to the distance between two adjacent pile positions during construction. Thus, when using the pile construction equipment, the drilling track 32 and the piling track 31 can be aligned with different pile positions. This allows the drilling mechanism 5 on the drilling track 32 to drill at one pile position, while the piling mechanism 4 on the piling track 31 drives piles at another pile position. By adjusting the equipment position only once, simultaneous operation at two pile positions can be achieved. This avoids the need to adjust the equipment position twice when drilling and driving piles, and also avoids the low utilization rate and operational efficiency caused by only one drilling mechanism 5 or piling mechanism 4 operating at a time while the other remains idle.

[0049] In this embodiment, to improve the adaptability of the equipment and meet the construction requirements of different work scenarios, and to enable the equipment body to complete the work on multiple pile positions with a single movement, thus avoiding the trouble and reduced work efficiency caused by moving a heavy equipment body during construction, a first position adjustment track 33 is designed on the equipment body. Specifically, the first position adjustment track 33 can be a longitudinal track that adjusts the longitudinal distance between the drilling track 32 and the piling track 31 to meet the work requirements of different pile position spacings in different work scenarios. Furthermore, the longitudinal track is installed on the side of the frame 3 facing the middle of the machine body 2, and one of the drilling track 32 and the piling track 31 is installed on the longitudinal track, thereby adjusting a single drilling track 32 or piling track 31 to change the distance between them. Alternatively, the drilling track 32 and the piling track 31 can be installed on the longitudinal track simultaneously, thus allowing for simultaneous longitudinal position adjustment of both the drilling track 32 and the piling track 31.

[0050] like Figure 2 As shown, the longitudinal track has at least two sub-longitudinal tracks 331 along the vertical direction. At least one sub-longitudinal track 331 is located on the side of the frame 3 facing the middle of the body 2, and at least one sub-longitudinal track 331 is located at the top of the frame 3. In this way, longitudinal position adjustment points for the drilling track 32 and the piling track 31 can be formed at different heights in the vertical direction, which can improve the vertical consistency of the drilling track 32 and the piling track 31 when adjusting their longitudinal positions, and facilitate the improvement of the overall equipment's operational accuracy.

[0051] The drilling track 32 has a first mounting body 321 and a first extension 322, and is mounted on the frame 3 through the first mounting body 321 and the first extension 322, wherein the drilling mechanism 5 is mounted on the first mounting body 321 and is vertically movable to complete the drilling operation. Specifically, the lower middle part of the first mounting body 321 is mounted on the sub-longitudinal track 331 of the frame 3 towards the center of the machine body 2, and the first extension 322 is located at the upper middle part of the first mounting body 321 and extends away from the center of the machine body 2, so that the first extension 322 is mounted on the sub-longitudinal track 331 at the top end of the frame 3, thereby enabling the drilling track 32 to be mounted on the sub-longitudinal track 331 at different positions, and achieving good consistency and stability when the drilling track 32 is longitudinally adjusted.

[0052] Similar to the structure of the drilling track 32, the pile driving track 31 has a second mounting body 311 and a second extension 312, wherein the pile driving mechanism 4 is mounted on the second mounting body 311 and is vertically movable to complete the pile driving operation. The lower middle part of the second mounting body 311 is mounted on the sub-longitudinal track 331 of the frame 3 towards the center of the machine body 2, and the second extension 312 is located at the upper middle part of the first mounting body 311 and extends away from the center of the machine body 2, so that the second extension 312 is mounted on the sub-longitudinal track 331 at the top end of the frame 3, thereby enabling the pile driving track 31 to be mounted on the sub-longitudinal track 331 at different positions, and achieving good consistency and stability when the pile driving track 31 is longitudinally adjusted. For the specific structure of the pile driving track 31, the drilling track 32 and the first position adjustment track 33, common track structures such as track slots or track strips can be used, and the first mounting body 321 and the second mounting body 311 corresponding to the movement along the first position adjustment track 33 can be mounted with moving wheels to move longitudinally along the track, and the drilling mechanism 5 and the pile driving mechanism 4 can also be mounted with moving wheels to move vertically along the track. The present embodiment does not make specific limitations on this.

[0053] <Embodiment Two>

[0054] In the present embodiment, the same parts as in Embodiment One are given the same reference numerals, and the same textual description is omitted.

[0055] As shown in Figure 3 The machine body 2 includes a support end 23 connected to the traveling mechanism 1 and a connecting rib 24 connecting the support end 23, and the connecting ribs 24 are arranged at intervals in the longitudinal direction, thereby forming spaces between adjacent connecting ribs 24, and the spaces are used to form the working hole 21 for the drill rod and the pile to pass through to drill and drive piles downward.

[0056] When the pile positions are relatively dense at the construction site, or the entire pile construction equipment is relatively large, more than one row of pile positions to be constructed can be formed inside the equipment, i.e., there are more than two rows of pile positions in the lateral direction inside the equipment. In order to move the entire pile construction equipment as little as possible and complete multiple operations at one time, a second position adjustment track 25 is designed on the equipment body. Specifically, the second position adjustment track 25 is installed on the machine body 2, and the machine frame 3 can move in the lateral direction along the second position adjustment track 25. In this way, the position of the machine frame 3 can be adjusted along the second position adjustment track 25 without moving the entire equipment, and the drilling and piling operations on the different rows of pile positions inside the equipment can be completed. In addition, in order to provide a working space for drilling and piling at different positions, working holes 21 are formed at different positions in the longitudinal and lateral directions on the machine body 2. The working holes 21 can be formed in the same way as the working holes 21 in Embodiment One, except that multiple working holes 21 can be formed in the lateral direction. In addition, the size of the machine body 2 can be reduced in the longitudinal direction, so that larger working spaces can be formed on both sides of the machine body 2 for drilling and piling. Of course, it can be understood that the above description is not a limitation on the structure of the machine body 2. Figure 3 In addition to the example, the working holes 21 can also be formed in the same way as in Embodiment One, i.e., working holes 21 are formed on the platform of the entire machine body 2, except that multiple working holes 21 can be formed in the lateral direction. In addition, the size of the machine body 2 can be reduced in the longitudinal direction, so that larger working spaces can be formed on both sides of the machine body 2 for drilling and piling. Of course, it can be understood that the above description is not a limitation on the structure of the machine body 2.

[0057] <Embodiment Three>

[0058] In this embodiment, the same parts as in Embodiment One are given the same reference numerals, and the same textual description is omitted.

[0059] In this embodiment, a pile construction method is provided, which uses the pile construction equipment of Embodiment One or Embodiment Two. The steps include:

[0060] S1: Move the pile construction equipment to the pile position where pile construction is needed, and adjust the drilling mechanism 5 to be aligned with the first pile position. Drive the drilling mechanism 5 by the power device 6 to drill the first pile position, thereby completing the drilling of the first pile position;

[0061] S2: Adjust the drilling mechanism 5 to be aligned with the second pile position, and adjust the piling mechanism 4 to be aligned with the first pile position. Drive the piling mechanism 4 by the power device 6 to pile the first pile position, and drive the drilling mechanism 5 by the power device 6 to drill the second pile position. In this way, the piling of the first pile position and the drilling of the second pile position can be completed at the same time;

[0062] After that, move the pile construction equipment to the next pile position according to step S2, and complete the drilling of the current pile position and the piling of the previous pile position at the same time. Repeat this process until the piling of all pile positions is completed.

[0063] In addition, when the interval between adjacent pile sites changes, the longitudinal spacing between the piling track 31 and the drilling track 32 is adjusted by the first position adjustment track 33, so that the spacing between the piling mechanism 4 mounted on the piling track 31 and the drilling mechanism 5 mounted on the drilling track 32 is adapted to the spacing between adjacent pile sites, thereby adapting to the working requirements of different pile site intervals in the working scene.

[0064] In addition, the longitudinal spacing between the drilling track 32 and the piling track 31 can be adjusted by the first position adjustment track 33, and the lateral spacing between the drilling track 32 and the piling track 31 can be adjusted by the second position adjustment track 25, so that the position of the equipment body is kept unchanged after moving once, that is, the positions of the drilling track 2 and the piling track 31 can be changed by the first position adjustment track 33 and the second position adjustment track 25, and the drilling and piling of multiple different pile sites can be completed, avoiding the trouble of moving the heavy equipment body for working on different pile sites, thereby improving the working efficiency.

[0065] In the case of no contradiction between the embodiments, at least part of the technical solutions in the embodiments can be recombined to form the essential technical solutions of the present application. Of course, the embodiments can also be mutually referenced or contained. It should be noted that the adaptive adjustment and modification (such as part of addition, part of deletion, and part of modification) made by those skilled in the art when recombining the technical means described in the embodiments will also fall within the protection scope of the present application.

[0066] The technical principles of the present application are described above in combination with the specific embodiments, but it should be noted that the above description is only for the purpose of explaining the principles of the present application, and cannot be interpreted in any way as a specific limitation on the protection scope of the present application. Based on the explanation herein, those skilled in the art can think of other specific embodiments or equivalent replacements of the present application without creative labor, which will fall within the protection scope of the present application.
