[0046] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.
[0047] like Figure 1-3 As shown in the embodiment of this application, a rebar protection device for pipe pile construction is proposed, comprising: a first side plate, which is a trapezoid with a 45° inclined lower side, and the long side of the first side plate is connected to the pipe pile; a second side plate, which is also a trapezoid with a 45° inclined lower side, and the long side of the second side plate is connected to the pipe pile; a third side plate, whose two sides are connected to the two short sides of the first and second side plates; a top plate, which is rectangular, with one side connected to the pipe pile and the other three sides connected to the top edges of the first, second, and third side plates respectively; and a bottom plate, which is a rectangular inclined surface with a 45° inclination, with one side connected to the pipe pile and the other three sides connected to the bottom edges of the first, second, and third side plates respectively; the first side plate, second side plate, third side plate, top plate, bottom plate, and pipe pile together form an installation cavity, and the rebar gauge is disposed inside the installation cavity.
[0048] The reinforcement gauge protection device for pipe pile construction provided in this application includes a first side plate, a second side plate, a third side plate, a top plate, and a bottom plate, with the reinforcement gauge sensing end extending out of the mounting cavity through the bottom surface.
[0049] During assembly, the left and right sides of the third side plate are respectively connected to the short sides of the first side plate and the second side plate. The top plate is located at the non-inclined end of the first and second side plates, and the bottom plate is located at the inclined end of the first and second side plates at 45°. When the assembly is completed, the protective device is a shell with one open side, which is the opposite side of the third side plate.
[0050] During assembly, the reinforcing bar should first be placed on the protruding reinforcing bar head inside the pipe pile, and then the protective device should be placed on the outside of the reinforcing bar. At the same time, the inclined bottom surface of the protective device should be close to the end of the pipe pile that is driven into the soil.
[0051] This technical solution isolates the rebar gauge from interference caused by surrounding rock fracturing, settlement, or soil heave around the pipe pile through a shell, ensuring the accuracy of the gauge's readings. Simultaneously, it prevents the gauge from being damaged by surrounding rock fracturing, settlement, or soil heave, thus avoiding situations where monitoring of rebar stress becomes impossible and improving the gauge's stability. Furthermore, the inclined bottom surface of this solution reduces the stress on the protective device shell when the pipe pile encounters upward soil heave, settlement, or gravel, further enhancing the stability of the protective device.
[0052] like Figure 1-3 As shown, the protection device also includes a cable interface, which is located on the top plate, and the rebar gauge is connected to an external display component through the cable interface.
[0053] In this technical solution, the protection device also includes a cable interface, which is located on the top plate. The cable interface is circular. During use, the cable can be extended through the cable interface and connected to the rebar gauge. The other end of the cable can be connected to the display device, and the construction personnel can observe the readings fed back by the rebar gauge.
[0054] like Figure 1-3 As shown, the protective device further includes: a bending wing plate, which is disposed on the upper side of the top plate connected to the pipe pile and on the lower side of the bottom plate connected to the pipe pile; the bending wing plate is provided with fixing holes.
[0055] In this technical solution, the protective device also includes two bent-up wing plates, one located at the upper end of the top plate near the open edge and the other at the lower end of the bottom plate near the open edge. Screw holes are provided on the bent-up wing plates. When connecting the protective device to the pipe wall, the device is fixed by passing the reinforcing bars protruding from the side wall of the pipe pile through the fixing holes in the bent-up wing plates.
[0056] like Figure 1-3 As shown, the first side plate, second side plate, third side plate, top plate and bottom plate are made of steel plates with a thickness of 3 to 5 ml.
[0057] In this technical solution, the thickness of the protective device shell is limited. Experimental analysis shows that protective devices within this thickness range can cope with most situations such as rock breakage, settlement, and soil sluice. Under non-extreme conditions, they can provide protection for the reinforcing bars.
[0058] like Figure 1-3 As shown, the outer sides of the first side plate, second side plate, third side plate, top plate and bottom plate are provided with anti-rust paint layer.
[0059] In this technical solution, an anti-rust paint layer is added to the outer wall of the protective device. Metal materials are prone to corrosion in soil environments. The anti-rust paint can prevent the protective device shell from becoming brittle due to corrosion and unable to resist soil and rock stress, thus further improving the stability of the steel reinforcement protection device.
[0060] like Figure 1-3 As shown, it also includes a pressure sensor, which is disposed inside the mounting cavity.
[0061] In this technical solution, the pressure sensor is installed inside the mounting cavity. Under normal conditions, the stress device is not under stress. When the rebar protection device breaks, the pressure sensor can simultaneously sense the pressure.
[0062] like Figure 1-3 As shown, the pressure sensor includes: a pressure-sensitive resistor disposed inside the mounting cavity and on the bottom surface; a signal processing unit electrically connected to the pressure-sensitive resistor; and a pressure feedback cable, one end of which is connected to the signal processing unit, and the other end of which extends through a cable interface and is connected to an external component.
[0063] In this technical solution, the pressure sensor includes a piezoresistive element, a signal processing unit, and a pressure feedback cable. The piezoresistive element is disposed on the bottom surface and on one side inside the mounting cavity. Under normal circumstances, the piezoresistive element will not receive pressure. When the housing of the protection device is damaged, the pressure sensor will be subjected to pressure.
[0064] In practical use, the pressure feedback cable can be shared with the rebar gauge cable to simplify the structure of the protection device.
[0065] like Figure 1-3 As shown, the pressure sensor includes: a display screen electrically connected to a pressure feedback cable, the display screen being used to display the pressure on the pressure-sensitive resistor fed back by the signal processing unit; and an alarm device electrically connected to the pressure feedback cable, the alarm device issuing an alarm when the pressure value fed back by the pressure feedback cable exceeds a threshold.
[0066] In this technical solution, the pressure sensor includes a display screen and an alarm. Since the pressure sensor reading should be zero under normal conditions and does not require real-time monitoring, an alarm is added. When the stress sensor feedback exceeds the threshold, the alarm sounds to remind construction personnel that the protective device has been damaged.
[0067] In actual construction, the display screen used by the pressure sensor can be shared with the display device that displays the feedback electrical signal of the rebar gauge.
[0068] like Figure 1-3 As shown, the protection device further includes: a first sliding groove, which is disposed on one side of the top plate located within the mounting cavity, and there are two first sliding grooves arranged parallel to each other on both sides of the cable interface; a sliding plate, which is slidably connected to the two first sliding grooves, and the sliding plate has a circular hole; and a short tube, which is disposed in the circular hole of the sliding plate, and the outer side wall of the short tube is connected to the inner edge of the circular hole of the sliding plate.
[0069] In this technical solution, the protective device also includes a first groove, a sliding plate, and a short pipe.
[0070] Because cables may sway during use, failure to allow for cable displacement may cause cable damage. Therefore, a first sliding groove is provided on one side of the top plate located in the mounting cavity, and a sliding plate is provided through the first sliding groove. The sliding plate has a round hole for the cable to pass through. When the cable is displaced by external force, the cable can drive the sliding plate to slide on the first sliding groove, thereby achieving a margin for cable displacement.
[0071] Due to the thickness limitation of the sliding plate, the pressure exerted by the sliding plate on the cable is relatively large when the cable reaches its displacement limit, which can easily damage the cable. Therefore, a short tube is added to the sliding plate. The cable passes through the sliding plate through the short tube, which can disperse the stress on the cable and increase the stability of the cable.
[0072] like Figure 1-3 As shown, the protective device further includes: a rebar hole, which is formed in the third side plate; three second sliding grooves, which are U-shaped and respectively disposed on the lower side and the left and right sides of the rebar hole; and a movable plate, which is movably connected to the third side plate through the second sliding grooves.
[0073] In actual use, there may be situations where the rebar ends are too long and need to be passed through the third side of the protective device. Therefore, rebar holes are added so that there is no need to drill holes in the third side plate on site during use.
[0074] Meanwhile, if the rebar head cannot pass through the third side plate, soil and rocks may enter the shell through the rebar opening, affecting the rebar gauge and pressure sensor. Therefore, a second chute and a movable plate are added. The second chute is a U-shaped chute that surrounds the outside of the rebar hole. The movable plate can be installed and removed through the second chute, thereby opening and closing the rebar hole. The choice can be made according to the site conditions during use.
