Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and in particular to a bearing capacity detection device and a detection method for a high pile cap. Background Art

[0002] At present, a high pile cap refers to a pile foundation cap whose bottom surface is above the foundation surface. The cap distributes the load on it to the pile foundation, and the pile foundation then transfers the load to the foundation.

[0003] The bearing capacity detection device of the high pile cap in the related art is as follows Figure 1 As shown, the detection device includes a jack 14, a fixed column 17, a support platform 7, a support block 8 and a counterweight 22. The fixed column 17 is set on the high pile cap 6, and the jack 14 is set on the fixed column 17. A plurality of support blocks 8 are set and stacked on both sides of the high pile cap 6. When the height of the support block 8 is higher than the height of the jack 14, the support platform 7 is set above the support block 8, and finally a plurality of counterweights 22 are placed on the support platform 7, so that the force between the counterweight 22 and the support platform 7 is greater than the upward force of the jack 14.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the overall height of the above-mentioned detection device is relatively high. When building the detection device or testing the detection device, the support block 8 or the counterweight block 22 is not properly placed, which may easily cause the center of gravity of the detection device to shift, thereby causing the detection device to collapse and cause a work accident. Summary of the invention

[0005] In order to improve the safety of the detection device during detection, the present application provides a bearing capacity detection device and a detection method for a high pile cap.

[0006] The present application provides a high pile cap bearing capacity detection device, which adopts the following technical solution:

[0007] A bearing capacity detection device for a high pile cap, comprising a support frame arranged on the ground, a clamping mechanism arranged on the support frame, the support frame comprising two support columns, the two support columns are located on opposite sides of the high pile cap, a support rod is arranged above the two support columns, a jack is arranged at the bottom of the support rod, a fixing column is arranged on the side of the jack away from the support rod, one end of the fixing column away from the support rod abuts against the upper end surface of the high pile cap; a support hole is opened on one side of the two support columns; the clamping mechanism comprises a first fixing rod, the first fixing rod is inserted into the support hole, and a counterweight block is arranged above the first fixing rod.

[0008] By adopting the above technical scheme, the clamping mechanism applies a downward force to the first fixed rod. During detection, the jack is started, and the jack applies a downward force to the high pile cap, and at the same time applies an upward force to the support rod, so that the support frame is subjected to an upward force. The force applied by the jack to the support frame abuts against the support frame by the clamping mechanism, making it difficult for the support frame to move, thereby successfully detecting the bearing capacity of the high pile cap; in addition, through the design of the support frame and the first fixed rod, the counterweight blocks do not need to be stacked high, thereby reducing the overall height of the detection device, lowering the center of gravity of the detection device and making it difficult to deviate, thereby improving the safety of the detection device.

[0009] Optionally, the ground is provided with a first bearing member and a second bearing member, and the ends of the first bearing member and the second bearing member away from the ground are both abutted against the lower end surface of the first fixing rod, and the first bearing member and the second bearing member are respectively located at the two ends of the support frame along the axial direction of the support hole.

[0010] By adopting the above technical solution, when the first bearing member and the second bearing member are not provided, the supporting surface of the first fixed rod only has the area where the lower end surface of the supporting hole contacts the first fixed rod. When the force exerted by the counterweight on the first fixed rod increases, the first fixed rod is easy to bend. By providing the first bearing member and the second bearing member to support the first fixed rod, the lower end surface of the first fixed rod has multiple supporting surfaces, so that the first fixed rod is not easy to bend and be damaged.

[0011] Optionally, the first bearing member includes a second fixed block arranged on the ground and an elastic block arranged on the second fixed block, and when the first fixed rod abuts against the lower end surface of the support hole, the first fixed rod abuts against the elastic block, and the elastic block is in a compressed state.

[0012] By adopting the above technical solution, when the first fixing rod applies a force to the elastic block, the elastic block is deformed, so that the first fixing rod is not easy to move, thereby improving the stability of the first fixing rod.

[0013] Optionally, a plurality of the first carriers are provided.

[0014] By adopting the above technical solution, when only one first bearing member is provided, most of the force of the first fixing rod is transmitted to the first bearing member, and the first bearing member is subjected to great force, so that the probability of damage to the first bearing member is also relatively large; and multiple first bearing members are provided to further share the gravity exerted on the first fixing rod, so that the first bearing member and the first fixing rod are not easily damaged; when one first bearing member is damaged, other first bearing members can support the first fixing rod, so that the detection device is not easily collapsed, thereby improving the safety during detection.

[0015] Optionally, a support plate is provided on the bottom surface of the support column, and a horizontal cross-sectional area of ​​the support plate is larger than a horizontal cross-sectional area of ​​the support column.

[0016] By adopting the above technical solution and arranging a support plate, the contact area between the support frame and the ground is increased, the pressure of the support frame on the ground is reduced, and the probability of ground collapse is reduced.

[0017] Optionally, a triangular block is provided on the support plate, and the side of the triangular block facing the support column is connected to the support column.

[0018] By adopting the above technical solution and setting the triangular blocks, the stability between the support plate and the support column can be increased, and the structural strength of the support plate and the support column can be increased.

[0019] Optionally, the clamping mechanism further includes a second fixing rod disposed on the first fixing rod, and a length direction of the first fixing rod is perpendicular to a length direction of the second fixing rod.

[0020] By adopting the above technical solution, after the second fixing rod is arranged on the first fixing rod, the space for placing the counterweight block is increased compared to the space for placing the counterweight block only on the first fixing rod, thereby increasing the number of second counterweight blocks placed and improving the force of the clamping mechanism on the support frame.

[0021] Optionally, an operating block is arranged on the ground, and an upper end surface of the operating block abuts against a lower end surface of the second fixing rod.

[0022] By adopting the above technical solution and providing the operating block, the force acting on the second fixing rod can be shared, so that the second fixing rod is not easily damaged and the service life of the second fixing rod is increased.

[0023] Optionally, a plurality of the second fixing rods are provided.

[0024] By adopting the above technical solution, multiple second fixing rods are set, the space for placing the second counterweight block is increased, and the force of the clamping mechanism on the first fixing rod is increased, that is, the force on the support frame is increased, so that when the jack is working, the support frame is not easily lifted by the jack.

[0025] A method for detecting the bearing capacity of a high pile cap comprises the following steps: Step 1, selecting a high pile cap to be detected;

[0026] Step 2: Install the jack on the high pile cap, install the support frame on the ground, make the support columns on the opposite sides of the high pile cap, and make the jack directly below the support rod;

[0027] Step 3: Install the first fixing rod into the supporting hole, install the first bearing member and the second bearing member below the first fixing rod, and install the clamping mechanism above the first fixing rod;

[0028] Step 4: Start the jack to test the bearing capacity of the high pile cap and collect the measured data.

[0029] By adopting the above technical solution, through steps one to four, the bearing capacity of the high pile cap is tested to understand the maximum bearing weight of the high pile cap.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The clamping mechanism applies a downward force to the first fixing rod. During the test, the jack is started, and the jack applies a downward force to the high pile cap, and at the same time applies an upward force to the support rod, so that the support frame is subjected to an upward force. The force applied by the jack to the support frame abuts against the support frame by the clamping mechanism, so that the support frame is not easy to move, thereby smoothly detecting the bearing capacity of the high pile cap; in addition, through the design of the support frame and the first fixing rod, the counterweight block does not need to be stacked high, the overall height of the detection device is reduced, the center of gravity of the detection device is lowered and not easy to deviate, and the safety of the detection device is improved;

[0032] 2. A second fixing rod is provided to increase the space for placing counterweights in the detection device, so that the detection device can carry more counterweights. BRIEF DESCRIPTION OF THE DRAWINGS

The support rod 12 is fixedly connected to the upper end surfaces of the two support columns 11, so that the support rod 12 is located directly above the high pile cap 6. A jack 14 is fixedly connected to the side of the support rod 12 facing the high pile cap 6. A fixed column 13 is arranged above the high pile cap 6. One end of the jack 14 away from the support rod 12 abuts against the end surface of the fixed column 13 away from the high pile cap 6.

[0044] Reference Figure 3 The support column 11 is fixedly connected to a support plate 15 on one side away from the support rod 12, and the horizontal cross-sectional area of ​​the support plate 15 is larger than the horizontal cross-sectional area of ​​the support column 11.

The two support columns 11 are each provided with a support hole 111, and the axes of the two support holes 111 are perpendicular to the length direction of the support rod 12. Two first fixing rods 21 are provided, and the two first fixing rods 21 are respectively inserted into the two support holes 111.

[0046] Reference Figure 2 When there is one counterweight 22, the counterweight 22 is disposed on the first fixed rod 21. When there are multiple counterweights 22, there are three ways to place the counterweights 22. First, the counterweights 22 can be arranged in an array along the axis of the first fixed rod 21; second, the counterweights 22 can be stacked; third, the first two placement methods exist at the same time. In this embodiment, there are multiple counterweights 22, and the third placement method is adopted.

[0048] Reference Figure 2 and Figure 3 At least one second bearing member 4 is provided, and the second bearing members 4 are distributed along the axis direction of the support hole 111. The structure of the second bearing member 4 is the same as that of the first bearing member 3.

[0049] A method for detecting the bearing capacity of a high pile cap comprises the following steps: Step 1, selecting a high pile cap 6 to be detected;

[0050] Step 2: Install the jack 14 on the high pile cap 6, install the support frame 1 on the ground, so that the support column 11 is located on the opposite sides of the high pile cap 6, and the jack 14 is located directly below the support rod 12;

[0051] Step 3: install the first fixing rod 21 into the supporting hole 111, install the first bearing member 3 and the second bearing member 4 below the first fixing rod 21, and install the pressing mechanism 2 above the first fixing rod 21;

[0052] Step 4: Start the jack 14 to detect the bearing capacity of the high pile cap 6 and collect the measured data.

[0053] The implementation principle of Example 1 is: the clamping mechanism 2 applies a downward force to the support frame 1; the jack 14 is started, applying a vertical downward force to the high pile cap 6, and applying an upward force to the support frame 1, so that the force driving the support frame 1 to rise and the force of the clamping mechanism 2 on the support frame 1 are offset, thereby smoothly detecting the high pile cap 6.

[0054] Example 2

[0055] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the clamping mechanism 2 also includes a second fixing rod 23, and the second fixing rod 23 is arranged above the first fixing rod 21, and the length direction of the second fixing rod 23 is perpendicular to the length direction of the first fixing rod 21.

[0056] Reference Figure 2 and Figure 4 The second fixing rod 23 is provided with a plurality of second fixing rods 23, and the plurality of second fixing rods 23 are arranged in an array along the length direction of the first fixing rod 21. The counterweight 22 is arranged above the second fixing rod 23, or the first fixing rod 21 and the second fixing rod 23 are both provided with the counterweight 22.

[0057] The implementation principle of Example 2 is: the space for placing the counterweight 22 is increased by the second fixing rod 23, so that the number of placed counterweights 22 can be increased, and the force of the clamping mechanism 2 on the support frame 1 can be improved.

[0058] Example 3

[0059] Reference Figure 5 The difference between this embodiment and embodiment 2 is that at least one operating block 5 is provided at both ends of the support frame 1 along the length direction of the second fixing rod 23. The operating block 5 is provided on the ground, and the upper end surface of the operating block 5 abuts against the lower end surface of the second fixing rod 23.

[0060] The implementation principle of the embodiment 3 is as follows: the operating block 5 supports the second fixing rod 23 so that the second fixing rod 23 is not easily damaged.

[0061] Example 4

[0062] Reference Figure 6 The difference between this embodiment and embodiment 1 is that the first bearing member 3 includes a second fixing block 32 and an elastic block 33. The elastic block 33 can be any elastic material such as a rubber pad, a plastic pad, a resin pad, a wooden pad, etc. In this embodiment, the elastic block 33 is a rubber pad.

[0063] Reference Figure 6 The sum of the height of the second fixing block 32 and the height of the elastic block 33 is slightly higher than the distance between the first fixing rod 21 and the ground. When the second fixing block 32 presses the first bearing member 3, the elastic block 33 is deformed. The structure of the second bearing member 4 is the same as that of the first bearing member 3.

[0064] The implementation principle of Example 4 is: when the first fixing rod 21 is placed on the elastic block 33, the elastic block 33 is compressed and deformed. When the counterweight block 22 is placed on the first fixing rod 21, the first fixing rod 21 and the second fixing block 32 are not easy to slide, thereby improving the stability of the detection device.
