Description

Technical Field

[0001] This invention belongs to the technical field of building construction testing equipment, specifically a device for detecting static load anchor bars of miniature seamless steel pipe piles in a confined space. Background Technology

[0002] Test piles are categorized into design test piles, pre-construction test piles, and post-construction test piles. Before foundation construction, test piles are conducted based on the soil characteristics and physical and mechanical properties described in the geological survey report, allowing for the selection of the piling machine. All projects require test piles after pile foundation construction is completed, and quality assessment and acceptance are performed based on the test pile reports. Traditional static load compressive strength testing chambers utilize a counterweight platform reaction device. The counterweight platform is constructed using sleepers, H-beams, and weights. The weight of the weights is transferred to the sleepers on the counterweight platform, and the pressure from the sleepers is transferred to the H-beams (including main beams and distribution beams). The pressure is then transferred to the counterweight platform reaction device between the pile and the H-beams. By activating the counterweight platform reaction device, the expected maximum test load of the test pile is applied in 10-15 equal increments. Finally, the reaction force readings of the counterweight platform reaction device are measured to determine whether the single pile compressive bearing capacity characteristic value of the test pile meets the requirements.

[0003] However, in the existing technology, although the above method is convenient to construct and is especially suitable for open sites, the stacking height is high due to the heavy load and concentrated stress. Therefore, it cannot be applied in confined spaces or small spaces. In addition, the actual transfer of the stacked load is costly, and the transportation and hoisting time is long. Furthermore, the actual foundation construction process requires the installation of anchor piles, resulting in poor actual testing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a device for detecting static load anchor bars of miniature seamless steel pipe piles in a confined space, which enables convenient testing of the pile body within a confined space.

[0005] The technical solution adopted in this invention is as follows: a device for detecting static load anchor bars of miniature seamless steel pipe piles in a confined space, comprising: a support mechanism for providing a stable support foundation;

[0006] A limiting mechanism, used to provide stable support during reverse thrust, is disposed on the support mechanism; and

[0007] Monitoring agencies are used to monitor the data obtained during the reverse engineering process.

[0008] The support mechanism is provided in two sets. Each set of the support mechanism includes two pads, a first support tube, multiple second support tubes and support components. The outer surfaces of the two pads are attached to each other. The first support tube slides through the top of the two pads. A retaining ring is sleeved on the outer surface of the first support tube. The bottom of the retaining ring is attached to the bottom of the two pads. A pressure frame is slidably inserted into the top of the multiple second support tubes. The support components are set on the multiple pressure frames.

[0010] Each set of support components includes a support rod, two extension rods, and multiple bolts. The two extension rods are threaded together, one of which slides through the corresponding pressure frame, and the top of one extension rod is threaded with a support bolt. The support rod is threaded to the bottom of the other extension rod, and the bottom of the support rod is in contact with the outer surface of the first support tube. The multiple bolts are slidably inserted into the top of the corresponding pressure frame, and the bottom of each bolt is in contact with the outer surface of the retaining ring.

[0011] The bottom of each pad is attached to the top of the corresponding second support tube, the bottom of each pad is attached to the top of the corresponding pressure frame, and multiple counterweights are provided on the top of each pad.

[0012] The limiting mechanism includes a steel beam body and a limiting component. Two sets of abutment frames are fixedly connected to the top of the steel beam body, and the limiting component is disposed on the two sets of abutment frames.

[0013] The limiting components are provided in two sets. Each set of limiting components includes multiple anchor bar bodies and a base plate. Each anchor bar body is slidably inserted into the corresponding abutment frame. Each anchor bar body has a clamp on its outer surface. The bottom of each clamp fits with the top of the corresponding abutment frame. Two limiting nuts are threadedly connected to the outer surface of each anchor bar body near the bottom edge. The base plate is slidably fitted between the outer surfaces of multiple anchor bar bodies. The top of the first support tube slides through the bottom of the base plate. The bottom of the support ring fits with the top of the base plate.

[0014] The monitoring mechanism includes a jack body, multiple displacement sensors, a carrier plate, and mounting components. The jack body is located at the top center of the carrier plate, and the multiple displacement sensors are all mounted on the mounting components, which are located on both sides of the jack body.

[0015] The installation components include two slide bars and multiple moving blocks. The two slide bars are located on both sides of the jack body. Two sliders are slidably embedded at the bottom of each slide bar. A jacking tube is rotatably connected to the bottom of each slider. A jacking rod is slidably inserted at the bottom end of each jacking tube. A jacking ring is threadedly connected to the outer surface of each jacking rod. Multiple moving blocks are slidably sleeved on the outer surface of the two slide bars. A positioning bolt is threadedly connected to the top of each moving block.

A second adjusting rod is threadedly connected inside each adjusting ring. Each displacement sensor is slidably embedded at one end of the corresponding second adjusting rod.

[0016] A method for using a static load anchor bar testing device for miniature seamless steel pipe piles in a confined space includes the following steps:

[0017] S1. Testing Setup: Based on the position of the test pile body, two sets of support mechanisms are respectively set on both sides of the center of the test pile body through the first support pipe. Then, by adding or removing counterweights, the counterweights can be pressed against the support ring by the pad plate, so that the first support pipe can be stably and vertically erected. At the same time, under the support of the counterweights, the steel beam body can be suspended above the test pile body, ensuring that the center point of the steel beam body coincides with the center point of the test pile body. Then, by rotating the limiting nut, the bottom plate gradually fits against the bottom of the support ring under the support of the limiting nut. Then, by rotating the support ring, the support ring can be pressed against the bottom plate by the position restriction of the first support pipe. The bottom plate can then be pressed against the steel beam body by the anchor bar body and the clamp, so that the bottom of the steel beam body can be tightly and stably pressed against the top of the counterweight. Thus, the steel beam body can be stably set above the test pile body. At this time, the carrier plate is placed on the horizontal top of the test pile body, so that the center of the carrier plate coincides with the center of the test pile body. At the same time, the jack body is set on the carrier plate. At the center of the plate, the output end of the jack body extends and fits against the bottom of the steel beam body. Then, the jacking pipe and slider are inserted into both sides of the test pile body through the jacking rod. Then, by rotating the top ring, the top ring can support and adjust the height of the jacking pipe. Then, the slider can support the sliding strip to be set horizontally on both sides of the test pile body. Then, by moving the moving block to the position of the sliding strip surface, one end of the second adjusting rod can be positioned above the carrier plate. At this time, by rotating and adjusting the first and second adjusting rods, when the displacement sensor is inserted into one end of the second adjusting rod, it is ensured that the output end of the displacement sensor can fit against the top of the carrier plate and that the displacement sensor is in a vertical position. Then, by extending the output end of the jack body, the test pile body can be subjected to a counter-thrust force under the support of the steel beam body. Then, by monitoring the pressure data of the jack body through the existing pressure sensor, and by monitoring the position movement data of the carrier plate through the displacement sensor, the actual compressive bearing capacity test data of the test pile body can be obtained.

[0018] S2. Adaptive Adjustment: Based on the actual site conditions, the first support pipe can be easily inserted vertically into both sides of the test pile body using the adjusting bolts. Then, the counterweight and pad can compress the abutment ring, enabling the first support pipe to provide a stable vertical support effect. At the same time, under the compression of the pad, the second support pipe, together with the pressure frame and the clamp, can increase the position restriction of the abutment ring. Meanwhile, the second support pipe, together with the pressure frame, support bolt, extension rod and support rod, can restrict the upward movement of the first support pipe, thereby enabling the support mechanism to provide the same support effect as the anchor pile. At the same time, with the support of the counterweight, the steel beam body can provide the required stable counter-thrust support in a limited space.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] (1) In this invention, during use, according to the position of the test pile body, two sets of support mechanisms are respectively set on both sides of the center of the test pile body through the first support pipe. Then, by adding or removing counterweights, the counterweights can be pressed against the support ring by the pad plate, so that the first support pipe can be stably and vertically erected. At the same time, under the support of the counterweights, the steel beam body can be suspended above the test pile body, while ensuring that the center point of the steel beam body coincides with the center point of the test pile body. Then, by rotating the limiting nut, the bottom plate gradually fits against the bottom of the support ring under the support of the limiting nut. Then, by rotating the support ring, the support ring can be pressed against the bottom plate by the position restriction of the first support pipe, so that the bottom plate can be pressed against the steel beam body by the anchor bar body and the clamp, so that the bottom of the steel beam body can be tightly and stably attached to the top of the counterweight, so that the steel beam body can be stably set above the test pile body. At this time, the carrier plate is placed at the top horizontal position of the test pile body, so that the center of the carrier plate coincides with the center of the test pile body. At the same time, the jack body is set at the center of the carrier plate. The output end of the jack is extended to fit against the bottom of the steel beam. The jacking pipe and slider are then inserted into both sides of the test pile body via the jacking rod. Rotating the jacking ring allows it to support and adjust the height of the jacking pipe, enabling the slider to support the horizontally positioned sliding strip on both sides of the test pile body. Moving the moving block to the surface of the sliding strip positions one end of the second adjusting rod above the carrier plate. Rotating the first and second adjusting rods ensures that the displacement sensor's output end is in contact with the top of the carrier plate and is vertical. Extending the output end of the jack, supported by the steel beam, allows the test pile body to experience a counter-thrust force. Existing pressure sensors monitor the pressure data of the jack body, while displacement sensors monitor the positional movement of the carrier plate, thus obtaining the actual compressive bearing capacity test data of the test pile body, enabling the equipment to efficiently perform its intended functions.

[0021] (2) In this invention, according to the actual site conditions, the first support pipe can be easily inserted vertically on both sides of the test pile body by adjusting the bolt. Then, the counterweight and the pad can squeeze the abutment ring, so that the first support pipe can provide a stable vertical support effect. At the same time, under the compression of the pad, the second support pipe, together with the pressure frame and the clamp, can increase the position restriction of the abutment ring. At the same time, the second support pipe, together with the pressure frame, support bolt, extension rod and support rod, can restrict the upward movement of the first support pipe, so that the support mechanism can provide the same support effect as the anchor pile. At the same time, the position and number of the support mechanism can be adjusted according to the actual use, so that the equipment can provide different support foundations in a limited space, thereby improving the versatility of the equipment in actual use. At the same time, with the support of the counterweight, the steel beam body can provide the required stable support for the reverse thrust in a limited space, so that the equipment can efficiently realize its intended function.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] For examples, please refer to [link / reference]. Figures 1-3 A device for detecting static load anchor bars of miniature seamless steel pipe piles in a confined space, comprising a support mechanism 1, a limiting mechanism 2, and a monitoring mechanism 3.

[0038] The details are as follows:

[0039] Please see Figures 4-9The support mechanism 1 is used to provide a stable support foundation. There are two sets of support mechanisms 1. Each set of support mechanisms 1 includes two pads 101, a first support tube 102, multiple second support tubes 106, and support components. The outer surfaces of the two pads 101 are fitted together. The first support tube 102 slides through the tops of the two pads 101. A retaining ring 105 is fitted onto the outer surface of the first support tube 102, and the bottom of the retaining ring 105 is fitted to the bottoms of both pads 101. Pressure frames 107 are slidably inserted into the tops of the multiple second support tubes 106. Support components are mounted on the multiple pressure frames 107. A support ring 103 is threaded onto the outer surface of each first support tube 102. An adjusting bolt 104 is slidably inserted into the top of each first support tube 102. Each set... Each support component includes a support rod 111, two extension rods 109, and multiple bolts 108. The two extension rods 109 are threaded together, with one extension rod 109 slidingly passing through the corresponding pressure frame 107. A support bolt 110 is threadedly connected to the top of one extension rod 109. The support rod 111 is threaded to the bottom of the other extension rod 109, and the bottom of the support rod 111 is in contact with the outer surface of the first support tube 102. Multiple bolts 108 are slidably inserted into the top of the corresponding pressure frame 107, with the bottom of each bolt 108 in contact with the outer surface of the retaining ring 105. The bottom of each pad 101 is in contact with the top of the corresponding second support tube 106, and the bottom of each pad 101 is in contact with the top of the corresponding pressure frame 107. Each pad 101 has a [missing information - likely a type of fastener or device]. Multiple counterweights 112, based on the position of the test pile body 4, are used to connect two sets of support mechanisms 1 on either side of the center of the test pile body 4 via the first support pipe 102. By adding or removing counterweights 112, the counterweights 112 can press against the retaining ring 105 through the pad 101, ensuring the first support pipe 102 is stably and vertically erected. Simultaneously, supported by the counterweights 112, the steel beam body 201 can be suspended above the test pile body 4, ensuring the center point of the steel beam body 201 coincides with the center point of the test pile body 4. The first support pipe 102 can be easily inserted vertically onto both sides of the test pile body 4 via the adjusting bolt 104. Furthermore, the counterweights 112 and the pad 101 press against the retaining ring 105, providing a level surface for the first support pipe 102. The support mechanism 1 provides a stable vertical support effect. Under the compression of the pad plate 101, the second support tube 106, together with the pressure frame 107 and the clamp 108, can increase the position restriction of the abutment ring 105. At the same time, the second support tube 106, together with the pressure frame 107, support bolt 110, extension rod 109 and support rod 111, can restrict the upward movement of the first support tube 102. Thus, the support mechanism 1 can provide the same support effect as the anchor pile. At the same time, the position and number of the support mechanism 1 can be adjusted according to the actual use, so that the equipment can provide different support foundations in a limited space, thereby improving the versatility of the equipment in actual use. With the support of the counterweight block 112, the steel beam body 201 can provide the required stable support for the reverse thrust in a limited space.

[0040] Please see Figure 10 The limiting mechanism 2 is used to provide stable support during reverse thrust. The limiting mechanism 2 is mounted on the support mechanism 1 and includes a steel beam body 201 and limiting components. Two sets of abutment frames 202 are fixedly connected to the top of the steel beam body 201. The limiting components are mounted on the two sets of abutment frames 202. There are two sets of limiting components in total. Each set of limiting components includes multiple anchor bar bodies 203 and a base plate 205. Each anchor bar body 203 is slidably inserted into the corresponding abutment frame 202. A clamp 204 is fitted onto the outer surface of each anchor bar body 203. The bottom of each clamp 204 is in contact with the top of the corresponding abutment frame 202. Two limiting nuts are threaded onto the outer surface of each anchor bar body 203 near the bottom edge. The base plate 205 slides... The movable sleeve is set between the outer surfaces of multiple anchor bar bodies 203. The top end of the first support tube 102 slides through the bottom of the base plate 205. The bottom of the support ring 103 and the top of the base plate 205 are in contact. By rotating the limiting nut, the base plate 205 gradually comes into contact with the bottom of the support ring 103 under the support of the limiting nut. Then, by rotating the support ring 103, the support ring 103 can squeeze the base plate 205 under the position restriction of the first support tube 102. The base plate 205 can then squeeze the steel beam body 201 through the anchor bar body 203 and the clamp 204, so that the bottom of the steel beam body 201 can be tightly and stably attached to the top of the counterweight block 112. Thus, the steel beam body 201 can be stably set above the test pile body 4.

[0041] Please see Figures 11-13The monitoring mechanism 3 is used to monitor the data obtained during the reverse thrust process. The monitoring mechanism 3 includes a jack body 311, multiple displacement sensors 310, a carrier plate 312, and mounting components. The jack body 311 is located at the top center of the carrier plate 312. The multiple displacement sensors 310 are all located on the mounting components, which are located on both sides of the jack body 311. The mounting components include two slide bars 305 and multiple moving blocks 306. The two slide bars 305 are located on both sides of the jack body 311. Two sliders 304 are slidably embedded at the bottom of each slide bar 305. A jacking pipe 303 is rotatably connected to the bottom of each slider 304. The bottom end of each jacking pipe 303 is slidably connected to the slide bar 306. A top rod 301 is inserted, and a top ring 302 is threadedly connected to the outer surface of each top rod 301. Multiple moving blocks 306 are slidably sleeved on the outer surfaces of two sliding strips 305. A positioning bolt 307 is threadedly connected to the top of each moving block 306. A first adjusting rod 308 is threadedly connected to one side of the outer surface of each moving block 306. An adjusting ring is rotatably connected to the bottom end of each first adjusting rod 308. A second adjusting rod 309 is threadedly connected inside each adjusting ring. Each displacement sensor 310 is slidably embedded in one end of the corresponding second adjusting rod 309. The carrier plate 312 is placed at the top horizontal level of the test pile body 4, so that the center of the carrier plate 312 coincides with the center of the test pile body 4. Simultaneously, the jack body 311 is positioned at the center of the carrier plate 312, and the output end of the jack body 311 is extended to fit against the bottom of the steel beam body 201. The jacking pipe 303 and slider 304 are then inserted into both sides of the test pile body 4 via the jacking rod 301. By rotating the top ring 302, the top ring 302 can support and adjust the height of the jacking pipe 303, thereby allowing the slider 304 to support the sliding strip 305 horizontally positioned on both sides of the test pile body 4. Then, by moving the moving block 306 to the surface of the sliding strip 305, one end of the second adjusting rod 309 is positioned above the carrier plate 312. At this point, the first adjusting rod 308 and the second adjusting rod are rotated and adjusted. When the displacement sensor 310 is inserted into one end of the second adjusting rod 309, it is ensured that the output end of the displacement sensor 310 is in contact with the top of the carrier plate 312 and that the displacement sensor 310 is in a vertical position. Then, by extending the output end of the jack body 311, and under the support of the steel beam body 201, the test pile body 4 can be subjected to a counter-thrust force. Then, by monitoring the pressure data of the jack body 311 through the existing pressure sensor, and by monitoring the position movement data of the carrier plate 312 through the displacement sensor 310, the actual compressive bearing capacity test data of the test pile body 4 can be obtained, so that the equipment can efficiently realize its intended functions.

[0042] The following is a detailed description of the method of using a static load anchor bar testing device for miniature seamless steel pipe piles in a confined space, provided by an embodiment of the present invention. The method of use includes the following steps:

[0043] Step 1, Testing Setup: Based on the position of the test pile body 4, two sets of support mechanisms 1 are respectively set on both sides of the center of the test pile body 4 through the first support pipe 102. Then, by adding or removing counterweights 112, the counterweights 112 can press against the abutment ring 105 through the pad 101, so that the first support pipe 102 can be stably and vertically erected. At the same time, under the support of the counterweights 112, the steel beam body 201 can be suspended above the test pile body 4, while ensuring that the center point of the steel beam body 201 coincides with the center point of the test pile body 4. Then, by rotating the limiting nut, the base plate 205 gradually fits against the support ring 10 under the support of the limiting nut. 3. At the bottom, by rotating the support ring 103, the support ring 103 can, under the position restriction of the first support pipe 102, squeeze the bottom plate 205. The bottom plate 205 can then, through the anchor bar body 203 and the clamp 204, drive the abutment frame 202 to squeeze the steel beam body 201. This allows the bottom of the steel beam body 201 to fit tightly and stably against the top of the counterweight block 112, thus allowing the steel beam body 201 to be stably positioned above the test pile body 4. At this time, the carrier plate 312 is placed at the horizontal top of the test pile body 4, so that the center of the carrier plate 312 coincides with the center of the test pile body 4. At the same time, the jack body 311 is placed at the center of the carrier plate 312. Simultaneously, the output end of the jack body 311 is extended to fit the bottom of the steel beam body 201. Then, the jacking pipe 303 and the slider 304 are inserted into both sides of the test pile body 4 through the jacking rod 301. Then, by rotating the top ring 302, the top ring 302 can support and adjust the height of the jacking pipe 303, and then the slider 304 can support the sliding strip 305 to be horizontally set on both sides of the test pile body 4. Then, by moving the moving block 306 to the position on the surface of the sliding strip 305, one end of the second adjusting rod 309 can be positioned above the carrier plate 312. At this time, by rotating and adjusting the first adjusting rod 308 and the second adjusting rod 309, the displacement sensor... When 310 is inserted into one end of the second adjusting rod 309, ensure that the output end of the displacement sensor 310 is in contact with the top of the carrier plate 312 and that the displacement sensor 310 is in a vertical position. Then, by extending the output end of the jack body 311, and under the support of the steel beam body 201, the test pile body 4 can be subjected to a counter-thrust force. Then, by monitoring the pressure data of the jack body 311 through the existing pressure sensor, and by monitoring the position movement data of the carrier plate 312 through the displacement sensor 310, the actual compressive bearing capacity test data of the test pile body 4 can be obtained, so that the equipment can efficiently perform its intended functions.

[0044] Step 2, Adaptation and Adjustment: Based on the actual site conditions, the first support pipe 102 can be easily vertically inserted into both sides of the test pile body 4 using the adjusting bolt 104. Then, the counterweight 112 and the pad 101 can compress the retaining ring 105, allowing the first support pipe 102 to provide stable vertical support. Simultaneously, under the compression of the pad 101, the second support pipe 106, in conjunction with the pressure frame 107 and the clamp 108, can further restrict the position of the retaining ring 105. Furthermore, the second support pipe 106, in conjunction with the pressure frame 107 and the support bolt 110... The extension rod 109 and the support rod 111 can restrict the upward movement of the first support tube 102, thereby enabling the support mechanism 1 to provide the same support effect as the anchor pile. At the same time, the position and number of the support mechanism 1 can be adjusted according to the actual use, so that the equipment can provide different support foundations in a limited space, thereby improving the versatility of the equipment in actual use. Meanwhile, through the support of the counterweight block 112, the steel beam body 201 can provide the necessary stable support for the reverse thrust in a limited space, so that the equipment can efficiently realize its intended functions.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
