Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to a device for static load testing of engineering piles with a high safety factor. Background Technology

[0002] The main criteria for determining the quality of engineering piles are bearing capacity and integrity. Bearing capacity refers to the pile's ability to resist loads, while integrity refers to the absence of defects in the pile itself. For most piles, bearing capacity usually refers to vertical bearing capacity, meaning that the settlement of the pile under load must be within a certain range. For various buildings and structures, settlement exceeding this range, especially uneven settlement, is the most detrimental. The primary method for testing the vertical compressive bearing capacity of various piles is to conduct a static load test on a single pile. Current static load tests for engineering piles typically use a direct gravity load method, which involves stacking counterweights on top of the pile head. When stacking counterweights, uneven stress on both sides can easily occur. As the weight difference between the two sides increases during the stacking process, the counterweights are prone to tipping over and falling due to uneven stress, posing a certain safety risk.

[0003] An existing static load testing device for engineering piles includes a bearing platform with a movably mounted buffer to cushion the pressure of the load-bearing blocks. A centering component is also mounted on the bearing platform to determine its position relative to the engineering pile. A connecting block is mounted on the side of the bearing platform, and a guide rod is movably mounted on the connecting block. A positioning mechanism is installed within the guide rod, which is inserted into the ground to prevent the bearing plate from overturning. This static load testing device for engineering piles, by incorporating the buffer, not only cushions and reduces vibration when the load-bearing blocks are stacked, but also allows for real-time adjustment of the subsequent stacking position of the load-bearing blocks based on the length changes of the telescopic rod. This ensures that the center of gravity of the load-bearing blocks is aligned with the central axis of the bearing platform and the engineering pile, preventing the bearing platform from overturning. Furthermore, the guide rod provides additional support to the bearing platform.

[0004] However, in the aforementioned prior art, multiple guide rods are disassembled and mounted on the connecting block. Each time they are used, they need to be installed one by one, which is a cumbersome process. If they are fixed on the connecting block, they will be inconvenient to carry. Summary of the Invention

[0005] The purpose of this invention is to provide a device for static load testing of engineering piles with a high safety factor, which solves the technical problem in the prior art where multiple guide rods are disassembled and installed on the connecting block, requiring sequential installation each time they are used, which is cumbersome. If they are fixed on the connecting block, they are inconvenient to carry.

[0006] To achieve the above objectives, the present invention provides a device for static load testing of engineering piles with a high safety factor, comprising multiple connecting blocks, a bearing platform, and four fixing mechanisms. One end of each connecting block has a rotating groove and two through grooves, with the rotating groove located between the two through grooves.

[0008] The storage component includes a storage tube and two support bases. The storage tube is slidably connected to the corresponding support base and is located between the two support bases.

[0009] The device for static load testing of engineering piles with high safety factor also includes a clamping mechanism, which is located on the lower end face of the bearing platform and between the two receiving tubes.

[0010] The buffer component includes multiple buffer springs, which are fixedly connected to the support platform and located inside the support platform. The multiple buffer springs are also fixedly connected to the placement plate and located on the lower end face of the placement plate.

[0011] The positioning mechanism includes a positioning screw and multiple positioning components. One end of the positioning screw is provided with two conical blocks.

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] First embodiment:

[0029] Please see Figures 1-4 ,in Figure 1 This is a front view of the first embodiment of the present invention. Figure 2 This is the invention Figure 1 Sectional view of line AA in the middle. Figure 3 This is the invention Figure 2 Sectional view of the middle BB line. Figure 4 This is the invention Figure 3 A magnified view of a section at point C.

[0030] The present invention provides a device for static load testing of engineering piles with a high safety factor, comprising multiple connecting blocks 101, a bearing platform 102 and four fixing mechanisms. The fixing mechanism includes two fixing rods 112, an adjusting screw 113, a connecting plate 114 and two storage components. The storage components include a storage tube 118 and two support seats 119.

[0031] In this specific embodiment, one end of the connecting block 101 has a rotating groove 103 and two through grooves 104, with the rotating groove 103 located between the two through grooves 104. A guide rod 105 is provided on the connecting block 101, and a positioning mechanism 106 is provided inside the guide rod 105. Both ends and the lower end face of the support platform 102 have multiple fixing holes 107. Multiple telescopic rods 108 and multiple buffer members 109 are provided inside the support platform 102, and placement plates 110 are provided on the multiple telescopic rods 108 and the multiple buffer members 109. The two ends of the support platform 102... Each end has multiple grooves 111, and the multiple connections are rotatably connected to the support platform 102 and located in the corresponding grooves 111. The guide rod 105 can be easily inserted into the ground to fix the support platform 102. The positioning mechanism 106 can improve the fixing effect. While the buffer 109 provides buffering, if the load blocks are not placed evenly, the placement plate 110 will become skewed. At this time, by observing the change in the length of the telescopic rod 108, the state change of the placement plate 110 can be observed, and the problem of the load block stacking can be found and adjusted accordingly.

[0032] The adjusting screw 113 has a rotating block 115 at one end and a rotating disk 116 at the other end. The connecting plate 114 has a threaded groove 117. Two fixing rods 112 are fixedly connected to the connecting plate 114 at both ends and are also engaged with the bearing plate, located in corresponding fixing grooves and passing through corresponding through holes. The adjusting screw 113 is threadedly connected to the connecting plate 114 and located in the threaded groove 117. The rotating block 115 is rotatably connected to the corresponding connecting block 101. Located within the rotating groove 103, the connecting plate 114 abuts against the corresponding connecting block 101 and is located on the end face of the connecting block 101. It is engaged with the support platform 102 via the fixing rod 112, thereby restricting the movement of the connecting block 101 and facilitating the operation of the guide rod 105. The adjusting screw 113 facilitates the movement of the connecting plate 114, thereby enabling the connecting plate 114 to drive the two fixing rods 112. The rotating block 115 facilitates the restriction of the movement of the adjusting screw 113, ensuring that the adjusting screw 113 can only rotate within the rotating groove 103.

[0033] Secondly, the two storage components are fixedly connected to the support platform 102 and symmetrically arranged below the support platform 102. The storage components facilitate the storage of the guide rod 105, thereby improving the fixing effect.

[0034] Meanwhile, the storage tube 118 is slidably connected to the corresponding support seat 119 and is located between the two support seats 119. The two support seats 119 are respectively fixedly connected to the bearing platform 102 and are located below the bearing platform 102. By sliding the storage tube 118 to one end of the corresponding support seat 119, aligning the guide rod 105 with the storage tube 118, and pushing the storage tube 118, the storage tube 118 is sleeved on the guide rod 105. The other end of the storage tube 118 is then sleeved on the other guide rod 105 according to the above operation. This method can improve the fixing effect of the guide rod 105.

[0035] When using the device for static load testing of engineering piles with a high safety factor according to this embodiment, by rotating the adjusting screw 113, the adjusting screw 113 is restricted by the rotating block 115 to rotate within the rotating groove 103, and the connecting plate 114 is driven to move horizontally, bringing the two fixed rods 112 out from the corresponding fixed grooves. Then, the connecting block 101 is rotated so that the guide rod 105 and the bearing platform 102 are horizontally symmetrically arranged. Finally, the adjusting screw 113 is rotated so that the two fixed rods 112 are engaged with the corresponding fixed grooves, thereby completing the storage of the guide rod 105, which facilitates the carrying of the device. This method effectively solves the technical problem that disassembling and installing multiple guide rods 105 on the connecting block 101 requires sequential installation each time it is used, which is cumbersome. If they are fixed on the connecting block 101, it will be inconvenient to carry.

[0036] Second embodiment:

[0037] Based on the first embodiment, please refer to Figures 5-8 ,in Figure 5 This is a front view of the second embodiment of the present invention. Figure 6 This is the invention Figure 5 Sectional view of the DD line in the middle. Figure 7 This is the invention Figure 6 Sectional view of the EE line. Figure 8 This is the invention Figure 7 A magnified view of a section at point F.

[0038] The present invention provides a device for static load testing of engineering piles with a high safety factor, and further includes a clamping mechanism 203. The buffer 109 includes a plurality of buffer springs 201. The positioning mechanism 106 includes a positioning screw 202 and a plurality of positioning elements. The positioning elements include a positioning spring 206, a baffle 207 and a positioning rod 208.

[0039] In this specific embodiment, the clamping mechanism 203 is disposed on the lower end face of the bearing platform 102 and is also located between the two receiving tubes 118. The clamping mechanism 203 can facilitate the clamping of the engineering pile, thereby facilitating the insertion of the guide rod 105 into the ground.

[0040] The buffer springs 201 are fixedly connected to the support platform 102 and located inside the support platform 102. The buffer springs 201 are also fixedly connected to the placement plate 110 and located on the lower end face of the placement plate 110. The buffer springs 201 can effectively buffer the placement plate 110.

[0041] Secondly, one end of the positioning screw 202 is provided with two conical blocks 204. The guide rod 105 has a movable groove 205. The positioning screw 202 is threadedly connected to the guide groove and is located in the movable groove 205, passing through the top of the movable groove 205. The two conical blocks 204 respectively abut against the corresponding positioning members and are located between the two corresponding positioning members. Multiple positioning members are symmetrically arranged on the inner wall of the movable groove 205, and are arranged symmetrically in pairs. By inserting the bottom end of the guide rod 105 into the ground and then rotating the positioning screw 202, the positioning screw 202 spirals into the guide rod 105 and drives the conical blocks 204 to press the positioning members into the ground, thereby fixing the position of the guide rod 105.

[0042] Meanwhile, the positioning spring 206 is sleeved on the positioning rod 208. The positioning spring 206 is fixedly connected to the guide rod 105 and located on the inner wall of the movable groove 205. The positioning spring 206 is also fixedly connected to the baffle 207 and located on the baffle 207. The baffle 207 is fixedly connected to the positioning rod 208 and located at one end of the positioning rod 208, and is also located in the movable groove 205. The two conical blocks 204 respectively abut against the corresponding baffles 207 and are located on the back of the baffles 207. The positioning rod 208 is slidably connected to the guide rod 105 and penetrates the inner wall of the movable groove 205. The conical blocks 204 abut against the baffles 207. While the baffles 207 compress the positioning spring 206, they drive the positioning rod 208 to insert into the ground, thus fixing the position of the guide rod 105.

[0043] When using the device for static load testing of engineering piles with a high safety factor according to this embodiment, the buffer spring 201 can easily buffer the placement plate 110. The bottom end of the guide rod 105 is inserted into the ground, and then the positioning screw 202 is rotated. The positioning screw 202 spirals into the guide rod 105 and drives the conical block 204 to press the positioning member into the ground, thereby fixing the position of the guide rod 105. The conical block 204 supports the baffle 207. The baffle 207 compresses the positioning spring 206 and drives the positioning rod 208 into the ground, thereby fixing the position of the guide rod 105.

[0044] Third embodiment:

[0045] The clamping mechanism 203 includes two clamping plates and an adjusting rod 301. The lower end face of the bearing platform 102 has two sliding grooves 305.

[0046] The clamping mechanism 203 also includes a handwheel 302, which is fixedly connected to the adjusting rod 301 and located at one end of the adjusting rod 301.

[0047] The clamping plate includes a slider 303 and a clamping plate body 304. The slider 303 is disposed on the clamping plate body 304.

The slider 303 is also slidably connected to the support platform 102 and is located in the corresponding groove 305.

[0048] Based on the second embodiment, please refer to Figures 9-11 ,in Figure 9 This is a three-dimensional perspective view of the third embodiment of the present invention. Figure 10 This is a front view of the third embodiment of the present invention. Figure 11 This is the invention Figure 10 A cross-sectional view of the GG line.

[0050] In this specific embodiment, the lower end face of the bearing platform 102 has two sliding grooves 305. The adjusting rod 301 has a bidirectional thread. The two clamping plates are respectively threaded to the adjusting rod 301 and sleeved on the adjusting rod 301. The two clamping plates are also slidably connected to the receiving platform and symmetrically arranged in the corresponding sliding grooves 305. The adjusting rod 301 is rotatably connected to the bearing platform 102 and passes through one end of the bearing platform, and is located between the two sliding grooves 305. The clamping plates can facilitate the clamping of the engineering pile, thereby facilitating the insertion of the guide rod 105 into the ground. The adjusting rod 301 can facilitate the transmission of the two clamping plates in a direction that brings them closer to each other or away from each other.

[0051] The handwheel 302 is fixedly connected to the adjusting rod 301 and is located at one end of the adjusting rod 301. The adjusting rod 301 can be easily rotated by the handwheel 302.

[0052] Secondly, the slider 303 is disposed on the clamping plate body 304. The slider 303 is threadedly connected to the adjusting rod 301 and sleeved on the adjusting rod 301. The slider 303 is also slidably connected to the bearing platform 102 and located in the corresponding groove 305. Through the connection between the slider 303 and the clamping plate body 304, the engineering pile can be clamped under the transmission of the adjusting rod 301, thereby facilitating the insertion of the guide rod 105 into the ground.

[0053] When using the device for static load testing of engineering piles with a high safety factor according to this embodiment, the connection between the slider 303 and the clamping plate body 304 facilitates the clamping of the engineering pile under the transmission of the adjusting rod 301, thereby facilitating the insertion of the guide rod 105 into the ground.
