[0024] ​To make the purposes, technical solutions, and advantages of the embodiments of the present disclosure clearer, further, the embodiments of the present disclosure are described below in further detail in conjunction with the embodiments and drawings, the illustrative embodiments and their descriptions of the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure, and do not serve as limitations on the embodiments of the present disclosure.

[0025] As shown in Figure 1 The anti-seepage wall hole stuck drill accident handling spade of the present application includes a plurality of key components, the design and assembly of these components aim to effectively handle the stuck drill accident in the anti-seepage wall hole, improve the safety and accuracy of operation. The spade mainly consists of a spade rod 1, a scraper 2, a support arm 3, a positioning pin 4 and an anti-deviation guide piece 5.

[0026] The spade rod 1 is the core component of the spade, mainly used for transmitting operating force in the hole and maintaining stable guidance. The spade rod 1 has sufficient length and strength to ensure that it can work effectively in a narrow space. At the same time, the design of the spade rod 1 also needs to consider the characteristics of corrosion resistance and wear resistance to adapt to the harsh hole environment.

[0027] The scraper 2 is arranged at the lower end of the spade rod 1 and is used for cutting and cleaning the hole wall. The edge of the scraper 2 is designed with a serrated structure, which can significantly enhance the cutting ability and cleaning effect. The scraper 2 is fixed on the spade rod 1 by screw connection or welding, ensuring firmness and reliability during operation.

[0028] The support arm 3 is symmetrically arranged on both sides of the spade rod 1 and is fixedly connected with the spade rod 1. The main function of the support arm 3 is to expand the supporting area of the spade in the hole, preventing sticking or deviation during operation. The support arm 3 is usually made of high-strength material and is fixed on the spade rod 1 by welding or screw connection, ensuring the stability and reliability of the entire spade.

[0029] The positioning pin 4 is arranged at the top end of the spade rod 1 and is fixedly connected with the spade rod 1. The function of the positioning pin 4 is to position the interface of the spade with the external operating device, ensuring that the operating force can be accurately transmitted to each part of the spade. The structure of the positioning pin 4 is simple and efficient, which can effectively prevent the loss of external operating force and ensure the accuracy of operation.

[0030] The anti-deviation guide piece 5 is installed on the upper part of the spade rod 1, above the scraper 2. The main function of the anti-deviation guide piece 5 is to prevent the spade from deviating due to water pressure during operation, ensuring that the spade can move in a straight line.

[0031] Specifically, the shovel rod 1 can be made of high-strength, corrosion-resistant alloy materials, and the surface finish and internal structure strength need to be ensured during processing. The serrated edge of the scraper 2 can be processed by precision tool machining technology, and after mold pressing and heat treatment, the hardness and wear resistance can be improved. The welding process of the support arm 3 should choose high-efficiency automatic welding equipment to ensure the strength and flatness of the weld. The positioning pin 4 can be processed by a precision machining center and surface treated to improve corrosion resistance and wear resistance. The anti-deviation guide piece 5 can be made of metal materials or composite materials with good elastic recovery performance, and can be formed by cold stamping or hot bending process.

[0032] The anti-seepage wall hole sticking accident handling shovel of the present application optimizes the design and process technology described above, aiming to solve the problem that the shovel is stuck or deviated during operation due to the narrow space in the hole and high water pressure, thereby affecting the working precision and safety. The effective guidance of the shovel rod 1 and the stable support of the support arm 3 ensure the stability of the shovel, and the existence of the anti-deviation guide piece 5 further enhances the ability of the shovel to move in a straight line in a high-pressure water environment. These technical features not only improve the safety and efficiency of the operation, but also greatly reduce the operation time and labor cost.

[0033] In one embodiment, the anti-seepage wall hole sticking accident handling shovel of the present application has a high-strength structural design and excellent corrosion resistance. Specifically, the shovel rod 1 is made of high-strength stainless steel material, with a diameter of 30 mm and a length of 5 meters. The design of the shovel rod 1 enables the entire shovel to maintain structural stability and corrosion resistance in a high-strength operating environment. The high-strength stainless steel material of the shovel rod 1 not only can withstand high-load operating pressure, but also can effectively resist chemical corrosion during construction, prolonging the service life.

[0034] For example, the manufacturing of the shovel rod 1 adopts precision casting and cold drawing process to ensure the consistency and strength of the material. Specifically, the high-strength stainless steel material is subjected to multiple processes such as high-temperature forging, cooling, and heat treatment to meet the design requirements in terms of mechanical properties. The shovel rod 1 is connected to other components such as the shovel head and handle through threads or welding, forming a solid whole. Such connection mode ensures the reliability and durability of the shovel in complex operating environment.

[0035] Specifically, the production and assembly of the shovel rod 1 require strict quality control. For example, high-strength stainless steel raw materials that meet the standards are selected, and after precision machining and inspection, the diameter is uniform and consistent without any defects. In actual use, the shovel rod 1 is connected to the shovel head and other auxiliary tools through special connecting pieces to ensure that the components are tightly and stably matched, thereby achieving efficient working effect.

[0036] In one embodiment, the surface of the shank 1 of the anti-seepage wall hole sticking accident handling shovel of the present application is subjected to hardening treatment, forming a hardened layer with a thickness of 5 mm. This hardened layer not only significantly improves the wear resistance of the shank 1, but also enhances its rust prevention ability, thereby prolonging the overall service life of the shovel. Through this hardening treatment, the shank 1 can maintain high stability and durability in harsh working environments. In addition, the hardened layer uniformly covers the entire outer surface of the shank 1, ensuring uniform distribution of surface finish and mechanical properties.

[0037] For example, in the process of technical implementation, surface quenching, nitriding or chrome plating methods can be used for hardening treatment of the surface of the shank 1. Specifically, by quenching the shank 1 at high temperature and then rapidly cooling it, a hardened layer with high hardness and uniform thickness is formed on its surface. This process requires strict control of temperature and time parameters to ensure that the quality and thickness of the hardened layer meet the design requirements. In another embodiment, a chemical nickel plating method can also be used to form a hardened layer up to 5 mm by depositing a layer of corrosion-resistant nickel alloy on the metal surface. These methods can effectively improve the surface properties of the shank 1.

[0038] Continuing to refer to Figure 1 In one embodiment, the outer surface of the shank 1 of the anti-seepage wall hole sticking accident handling shovel of the present application is provided with a plurality of annular protrusions 6, which are distributed along the length direction of the shank 1. The spacing between every two adjacent annular protrusions 6 is 10 cm, and the height of each annular protrusion 6 is 2 mm. The design of the annular protrusions 6 aims to enhance the friction between the shank 1 and the hole wall, thereby effectively reducing the risk of sticking during the handling of sticking accidents. These annular protrusions 6 are formed on the outer surface of the shank 1 through precision machining, ensuring the consistency of their shape and size.

[0039] Specifically, the annular protrusions 6 can be machined on the outer surface of the shank 1 through turning or casting process. For example, using a numerical control lathe or precision casting equipment, the outer surface of the shank 1 is machined multiple times according to the size and position requirements on the design drawing, forming the required annular protrusions 6. In this way, not only the spacing and height accuracy of the annular protrusions 6 can be guaranteed, but also the production efficiency and product quality can be improved. In addition, these annular protrusions 6 are uniformly distributed in the length direction of the shank 1, to ensure that the shank 1 can maintain good contact with the hole wall during use, enhance the friction and reduce the risk of sticking.

[0040] In one embodiment, the blade 2 of the diaphragm wall hole sticking incident handling spade of the present application is made of high-hardness alloy material to ensure that it has sufficient strength and wear resistance to adapt to harsh working conditions. The blade 2 is designed with serrated edges, and the angle of each serration is precisely 45 degrees. This specific angle allows the serrations to better cut into and cut off the residues on the hole wall when rotating or moving linearly. The spacing between two adjacent serrations is 5 mm, which ensures sufficient cutting force without causing excessive friction and wear.

[0041] Further, the blade 2 is fixed to the main body of the spade by high-strength connectors to ensure stability and reliability during operation. The surface of the blade 2 is treated with special hardening to improve its corrosion resistance and prolong its service life. In practical applications, the part of the blade 2 that contacts the hole wall is precisely ground to ensure a smooth surface without burrs, thereby reducing unnecessary friction and wear with the hole wall.

[0042] In one embodiment, the blade 2 is fixed to the front end of the spade by bolts or other high-strength connectors, or is integrally formed with the spade, to ensure that it can remain in place under stress. The shape of the blade 2 matches the hole diameter, allowing it to closely fit the hole wall when inserted into the hole, thereby more effectively cleaning it.

[0043] As shown in Figure 2 In one embodiment, the serrated edge of the blade 2 of the diaphragm wall hole sticking incident handling spade of the present application is provided with a wear-resistant coating 7 with a thickness of 3 mm. The blade 2 is located in the main working part of the spade, and its shape and size are designed according to the actual application requirements to ensure that it can effectively remove debris from the stuck part. The main body of the blade 2 is made of high-hardness alloy material to ensure its structural stability and durability under complex construction conditions. The serrated edge is specially treated with a wear-resistant coating 7, which is made of high-strength ceramic or tungsten carbide material and has excellent wear resistance and corrosion resistance.

[0044] Specifically, the wear-resistant coating 7 is uniformly sprayed on the serrated edge of the blade 2 by physical vapor deposition (PVD) or chemical vapor deposition (CVD) process. For example, an arc spraying method can be used to heat the coating material to a molten state, and then use high-speed airflow to spray it onto the pretreated surface of the blade 2 to form a dense and uniform coating layer. The pretreatment includes steps such as surface cleaning and roughening treatment to improve the bonding strength between the coating and the substrate. This design not only enhances the wear resistance of the blade 2, but also significantly prolongs the service life of the spade.

[0045] With reference to Figure 2In one embodiment, the upper part of the blade 2 of the diaphragm wall hole sticking accident handling spade of the present application is provided with a rubber sealing ring 8, which has the same diameter as the spade rod 1 and a width of 2 cm. This sealing ring effectively isolates the mud from entering the connection between the blade 2 and the spade rod 1, preventing corrosion and damage to the connection. The specific installation position of the sealing ring is on the upper part of the blade 2, around the junction between the outer edge of the blade 2 and the spade rod 1. In this way, the sealing ring tightly fits the joint between the two components, forming an effective sealing barrier.

[0046] To achieve this feature, during the design and manufacturing process, a mounting groove for the sealing ring is reserved on the upper part of the blade 2, which has a diameter matching that of the spade rod 1, ensuring that the sealing ring can be tightly installed thereon. For example, a 2 cm wide annular groove can be machined on the blade 2, and the rubber sealing ring 8 is embedded in the groove, and then fixed securely (such as by adhesion or mechanical clamping) to ensure that the sealing ring does not shift. In this way, even in complex working environments, the sealing ring can effectively block the intrusion of mud, protecting the key connection parts of the spade.

[0047] In one embodiment, as shown in Figure 3 The support arm 3 of the diaphragm wall hole sticking accident handling spade of the present application has a specific geometric shape and size, designed to enhance its lateral stability. The cross-section of the support arm 3 is designed as an equilateral triangle, with each side measuring 10 cm in length and 15 cm in height. This triangular cross-section of the support arm 3 can significantly improve the stability and rigidity of the spade in complex environments, preventing deformation or breakage due to external forces. The support arm 3 is usually installed on the main structure of the spade, ensuring the balance and stability of the entire device during operation.

[0048] Specifically, the support arm 3 is fixed by welding to the main beam or other key parts. The welding points are distributed at the apex and the central bottom edge of the support arm 3, ensuring that the three sides of the triangle can uniformly transmit loads, further enhancing the overall mechanical strength and anti-deformation ability. For example, during construction, when the spade encounters a sticking situation, this structure of the support arm 3 can provide additional support to prevent the spade from shifting or being damaged by external forces.

[0049] In one embodiment, to further enhance the durability and reliability of the support arm 3, high-strength alloy materials can be chosen to manufacture the support arm 3. In this way, not only can it resist the compressive stress of soil and rock in complex underground environments, but it can also maintain good performance in repeated operations. In addition, the surface of the support arm 3 can also be treated to resist corrosion, prolonging its service life.

[0050] In one embodiment, the support arm 3 of the diaphragm wall hole sticking accident handling shovel of the present application is provided with a reinforcing rib plate 9 at the connection with the shovel rod 1. The thickness of the reinforcing rib plate 9 is 2 mm. By providing the reinforcing rib plate 9, the structural strength of the support arm 3 under high load operation can be effectively improved, ensuring the stable operation of the shovel in complex construction environment. The support arm 3 is firmly connected with the shovel rod 1 through the reinforcing rib plate 9, forming a stable connection structure. The connection between the support arm 3 and the shovel rod 1 adopts welding or bolt fixing process, ensuring that the connection has sufficient rigidity and durability. The specific design of the reinforcing rib plate 9 takes into account the stress distribution under high load working condition, and by reasonably setting the position and shape of the rib plate, the support arm 3 can withstand greater load.

[0051] For example, a steel plate with a thickness of 2 mm can be used as the reinforcing rib plate 9 at the connection between the support arm 3 and the shovel rod 1. The reinforcing rib plate 9 is connected with the support arm 3 and the shovel rod 1 through welding to form an integral structure. In order to ensure the reliability and durability of the connection, the welding process needs to be strictly controlled to ensure the quality and strength of the weld. In addition, the position of the reinforcing rib plate 9 should be as close as possible to the junction of the support arm 3 and the shovel rod 1, so as to better disperse the stress caused by high load and enhance the stability of the overall structure.

[0052] In one embodiment, the reinforcing rib plate 9 of the diaphragm wall hole sticking accident handling shovel of the present application is made of high-strength aluminum alloy material, which has excellent strength and corrosion resistance and can maintain stability for a long time in harsh working environment. The reinforcing rib plate 9 is firmly connected to the support arm 3 and the shovel rod 1 through welding, ensuring the strength and stability of the entire structure. The support arm 3, as a key component connecting the reinforcing rib plate 9 and the shovel rod 1, not only needs to withstand greater external force, but also needs to ensure the smoothness and flexibility of the entire handling shovel during use. Therefore, the position and connection method of the reinforcing rib plate 9 are particularly critical, which can effectively disperse external force and avoid damage caused by local stress concentration.

[0053] In one embodiment, the reinforcing rib plate 9 is located at the connection between the support arm 3 and the shovel rod 1, which is a region with relatively concentrated stress in the entire structure. By adding the reinforcing rib plate 9, the structural strength at this position can be significantly improved. Specifically, the contact surface between the reinforcing rib plate 9 and the support arm 3 and the shovel rod 1 is processed by precise mechanical processing to ensure that the welding surface is flat and gapless. The welding of the reinforcing rib plate 9 with the support arm 3 and the shovel rod 1 adopts advanced welding technology such as laser welding or tungsten inert gas welding, ensuring the quality of the weld and the durability of the welded part, and ensuring stable work under high load working condition. For example, in a specific implementation case, the reinforcing rib plate 9 is preheated and cooled after welding, and then subjected to flaw detection to ensure that there is no crack or porosity, thereby ensuring its long-term reliable performance.

[0054] In one embodiment, the positioning pin 4 of the diaphragm wall hole sticking incident handling spade of the present application has a specific shape and size. The positioning pin 4 is, for example, a hexagonal pin, and the design of such a hexagonal structure can provide multiple contact surfaces to facilitate accurate alignment and stable connection with the connecting part of the external operating device. In addition, the diameter of the positioning pin 4 is 15 mm, which ensures that there is enough contact area when connected, avoiding the problem of unstable connection caused by too small diameter. The height of the positioning pin 4 is 20 mm, which ensures the strength of the connection and does not affect the operational flexibility of the overall equipment due to excessive length.

[0055] To ensure that the positioning pin 4 can be stably installed and effectively transmit force, the positioning pin 4 is installed on one side of the handling spade body through threaded connection or embedded fixation, ensuring its firmness and reliability. The hexagonal part of the positioning pin 4 is exposed on the outer surface of the handling spade, so that the external operating device can quickly identify and interface with it. Through the multiple contact surfaces of the hexagonal shape, the pushing and pulling force provided by the external operating device can be effectively transmitted, enabling the handling spade to effectively handle the sticking incident when encountered.

[0056] For example, the positioning pin 4 that meets the above size and shape requirements can be made by precision casting or machining. Then the positioning pin 4 is fixed at the predetermined position of the spade body, using high-strength threaded connection or embedded fixation method to ensure that it will not loosen or fall off during use. This design makes the positioning pin 4 not only has the function of quick docking, but also can maintain stability and reliability during force transmission.

[0057] In one embodiment, the anti-deviation guide piece 5 of the diaphragm wall hole sticking incident handling spade of the present application is circular with a diameter of 25 mm and a thickness of 3 mm, and its surface is smooth. The anti-deviation guide piece 5 is installed at the front end of the spade and can be in close contact with the hole wall. The design of its diameter and thickness ensures the stability and durability of the guide piece in the hole, while also reducing the risk of lateral deviation during operation. Specifically, the circular design of the anti-deviation guide piece 5 not only helps to reduce friction with the hole wall, but also improves stability under water pressure. In this way, the anti-deviation guide piece 5 can effectively ensure the straight-line movement of the spade in the hole, avoiding deviation caused by water pressure or other external factors.

[0058] For example, a mounting hole with a diameter slightly larger than 25 mm can be reserved at the front end of the diaphragm wall hole sticking incident handling spade, and the anti-deviation guide piece 5 is embedded and fixed. To ensure the stable installation of the anti-deviation guide piece 5, appropriate fasteners such as threads or buckles can be added in the mounting hole to ensure the close combination of the anti-deviation guide piece 5 and the spade body. In addition, the smooth surface treatment of the anti-deviation guide piece 5 can be achieved through precision polishing or other processes to ensure that the friction with the hole wall is reduced during actual operation, further improving the operational performance and reliability of the spade.

[0059] In actual operation, when the device is in use, the anti-seepage wall hole sticking accident handling shovel realizes efficient treatment of hole sticking problems through the precise cooperation of each component. First, the shovel rod 1 is used to transmit operating force in the hole and maintain stable guidance, ensuring that the entire shovel can run smoothly in a narrow space. The operator inserts the shovel into the hole through the shovel rod 1, and uses the rigidity and stability of the shovel rod 1 to ensure that the operating force can be accurately transmitted to the working part of the shovel.

[0060] Next, the scraper 2 is arranged at the lower end of the shovel rod 1, which is responsible for cutting and cleaning the hole wall. The edge of the scraper 2 is designed with a serrated structure, which greatly enhances its cutting ability and can effectively cut off the soil or rock layer that has stuck the drill, thereby gradually resolving the sticking situation. During cutting and cleaning, the scraper 2 will rotate or move up and down constantly, which requires the shovel rod 1 to provide sufficient support and guidance to ensure that the scraper 2 always adheres to the hole wall and completes accurate work.

[0061] In order to further improve the stability and efficiency of the shovel, support arms 3 are symmetrically arranged on both sides of the shovel rod 1. These support arms 3 are fixedly connected with the shovel rod 1, and they can expand the support area of the shovel in the hole, preventing the shovel from sticking or deviating during operation. When the shovel moves up and down in the hole, the support arms 3 can effectively disperse the operating force, reduce the friction between the shovel and the hole wall, and avoid damage to the equipment caused by excessive local pressure.

[0062] The top end of the shovel rod 1 is provided with a positioning pin 4, which mainly functions to ensure the accurate positioning of the shovel interface with external operating devices. Through the guidance of the positioning pin 4, the operator can accurately transmit the force of external equipment to each part of the shovel, ensuring the smooth progress of the operation. At the same time, the anti-deviation guide piece 5 is installed on the upper part of the shovel rod 1, above the scraper 2. The function of the anti-deviation guide piece 5 is to prevent the shovel from deviating due to water pressure and other reasons during operation, ensuring that the shovel always moves in a straight line, improving the safety and effectiveness of the operation.

[0063] Through the cooperation of the above-mentioned components, the anti-seepage wall hole sticking accident handling shovel can quickly and efficiently solve the problem of hole sticking, ensuring the smooth progress of engineering construction.

[0064] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the disclosed embodiments, and it should be understood that the above description is only a specific embodiment of the disclosed embodiments and does not limit the protection scope of the disclosed embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the disclosed embodiments shall be included in the protection scope of the disclosed embodiments.
