Description

Technical Field

[0001] The utility model relates to the technical field of cutting construction, and particularly relates to a monitoring device for deep cutting construction. Background Art

[0002] Deep cutting construction refers to the process of a large amount of earthwork excavation below the ground surface in engineering construction, especially in linear projects such as roads, railways or pipelines, in order to reach the design elevation or cross obstacles. A cutting is a recessed part or passage built by excavating soil or rock below the ground surface.

[0003] In deep cutting construction, due to complex geological conditions and poor soil stability, safety accidents such as slope instability and collapse are likely to occur, seriously threatening the safety of construction personnel and equipment. At present, the detection mainly relies on manual experience judgment, which is difficult to ensure real-time and accuracy, increasing the construction risk. Content of the Utility Model

[0004] The purpose of the utility model is to provide a monitoring device for deep cutting construction, which can effectively monitor the deformation of the side wall surface of the deep cutting and reduce the construction risk.

A receiving plate is fixedly arranged on the top wall of the ground cone inserting rod, and a marking point is arranged at the middle position of the receiving plate. The marking point of the receiving plate is arranged to face the infrared ray emitted by the infrared emitter.

[0006] In a preferred scheme, a handle is integrally arranged at the tail end of the side wall inserting rod, and an elastic member is arranged between the handle and the guide cylinder. The elastic member includes a spring, the spring is sleeved on the side wall inserting rod, one end of the spring is fixedly connected to the handle, and the other end is fixedly arranged on the guide cylinder.

[0007] In a preferred scheme, multiple circles of marking lines are evenly spaced circumferentially outward from the marking point on the top wall of the receiving plate, and each circle of marking lines is correspondingly provided with scale lines.

[0008] In a preferred scheme, multiple contact rods are hinged circumferentially on the contact plate. The hinge axis of the contact rod and the contact plate is perpendicular to the side wall inserting rod. Baffles are fixedly arranged on the outer sides of the hinge positions of the contact plate for restricting the outward swing of the contact rod.

[0009] In a preferred scheme, an extension rod is slidably inserted on the side of the contact rod away from the contact plate, and a pointed cone rod is fixedly arranged on the side of the extension rod facing the side wall of the cutting trench.

[0010] In a preferred embodiment, telescopic rods are provided between the positions of multiple abutting rods and the side wall insertion rods near the front ends. The two ends of the telescopic rods are respectively hinged to the abutting rods and the side wall insertion rods, and the abutting rods are swung to the position perpendicular to the abutting plate at the maximum.

Detailed implementation mode

[0021] The following is further described in conjunction with specific embodiments. Refer to Figures 1-3 As shown, the utility model is a deep cut slope construction monitoring device, including a side wall inserting rod 1. The head end of the side wall inserting rod 1 is in a sharp cone shape to facilitate insertion into the side wall of the cut slope trench. A guide cylinder 11 is slidably sleeved on the side wall inserting rod 1. One side of the guide cylinder 11 close to the side wall of the cut slope trench is coaxially installed with an abutting plate 12. The abutting plate 12 can also be welded to the guide cylinder 11. The abutting plate 12 is circular. When installed, one side of the abutting plate 12 abuts against the side wall;

[0022] Among them, the infrared emitter 3 is fixedly installed on the guide cylinder 11 and is arranged towards the bottom wall of the cut slope trench. The ground cone inserting rod 4 is used to be inserted into the bottom wall of the cut slope trench. A receiving plate 41 is welded to the top wall of the ground cone inserting rod 4. The receiving plate 41 is circular. A marking point 411 is arranged at the middle position of the receiving plate 41. The marking point 411 of the receiving plate 41 is used to be directly opposite to the infrared rays emitted by the infrared emitter 3. Multiple circles of marking lines 412 are evenly spaced circumferentially outward from the marking point 411 on the top wall of the receiving plate 41. Each circle of marking lines 412 is correspondingly provided with scale lines 413, so that it is convenient for the staff to observe the specific deformation distance. A multi-pyramid 7 is fixedly arranged at the position of the marking point 411. The top of the multi-pyramid 7 is in a sharp cone shape. A reflective film layer 71 is coated on the outer wall of the multi-pyramid 7. The reflective film layer 71 has the function of reflecting infrared rays and is convenient for the staff to observe. The reflective film layer 71 can also be a common reflective film.

[0023] Refer to Figure 1 and Figure 2 To drive the abutting plate 12 on the guide cylinder 11 to abut against the side wall of the cut slope trench, a handle 13 is integrally provided at the tail end of the side wall inserting rod 1. The handle 13 can also be welded to the side wall inserting rod 1. The elastic member 2 is a spring 21. The spring 21 is sleeved on the side wall inserting rod 1. One end of the spring 21 is fixed on the handle 13, and the other end is fixed on the guide cylinder 11. The handle 13 is convenient for the staff to operate.

[0024] Refer to Figure 1 and Figure 2, a plurality of abutting rods 5 are hinged and installed along the circumferential direction of the abutting plate 12. The cross-section of the abutting rod 5 is square. The hinge axis of the abutting rod 5 and the abutting plate 12 is perpendicular to the side wall inserting rod 1. Baffles 121 are welded at the hinged positions of the abutting rod 5 and the abutting plate 12. The baffle 121 is used to limit the outward swing of the abutting rod 5, so that the inner surface of the abutting rod 5 and the inner surface of the abutting plate 12 are in the same plane. An extension rod 51 is slidably inserted on the side of the abutting rod 5 away from the abutting plate 12. A pointed cone rod 52 is welded on the side of the extension rod 51 facing the side wall of the cutting ditch. The pointed cone rod 52 can facilitate the insertion into the side wall of the cutting ditch. The purpose of setting the extension rod 51 is to increase the contact area between the device and the side wall. Also, the length of the abutting rod 5 is much greater than the length of the extension rod 51. When the side wall deforms and squeezes any one of the abutting rods 5 or the extension rod 51, the abutting rod 5 or the extension rod 51 transmits the force to the abutting plate 12, and the position of the abutting plate 12 moves, thereby changing the position of the infrared emitter 3. Finally, it is reflected at one end of the receiving plate 41, and the position of the infrared ray on the receiving plate 41 changes, so as to judge the deformation of the cutting ditch wall surface.

[0025] The telescopic rod 6 includes two parts, and its structure is similar to the sliding structure of the abutting rod 5 and the extension rod 51. The cross-section of the telescopic rod 6 is triangular, and a plurality of hollow holes 61 are provided on the telescopic rod 6.

[0026] Refer to Figure 2 , telescopic rods 6 are provided between the plurality of abutting rods 5 and the positions of the side wall inserting rod 1 close to the front end. The two ends of the telescopic rod 6 are respectively hinged on the abutting rod 5 and the side wall inserting rod 1. A plurality of hollow holes 61 are provided on the telescopic rod 6, so that soil can enter the hollow holes 61, which can increase the contact area between the telescopic rod 6 and the side wall soil. When the side wall soil is stressed, there is not only the friction force on the outside of the telescopic rod 6, but also the extrusion force in the holes. Finally, the force is transmitted to the abutting rod 5 until the change in the position of the infrared emitter 3 is reflected.

[0027] The working process of this embodiment is as follows: First, insert the side wall inserting rod 1 into the cutting ditch wall surface, and at the same time insert the ground cone inserting rod 4 into the bottom wall of the cutting ditch. After the installation is completed, the infrared ray emitted by the infrared emitter 3 needs to be directly opposite the marking point 411 on the receiving plate 41. After the cutting ditch wall surface deforms, it will drive the guide cylinder 11 and the abutting plate 12 to move outward as a whole, and even drive the side wall inserting rod 1 to move outward together. The plurality of abutting rods 5 and the extension rods 51 can expand the area abutting against the cutting ditch wall surface. After the cutting ditch wall surface deforms, the feedback of the cutting ditch wall surface deformation can be received more effectively. The position of the infrared ray emitted by the infrared emitter 3 projected on the marking point 411 will move, and the construction personnel can observe it, so as to effectively monitor the deformation of the deep cutting ditch wall surface. The construction personnel can take targeted protective measures and reduce construction risks.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
