Description
Technical Field
[0001] The present application relates to the field of cleaning tools, and in particular to a tool for removing the soil between inclined group piles. Background Art
[0002] High-pile wharves have the advantages of light self-weight, easy berthing, and strong adaptability to the depth of silt, so they are widely used in various ports.
[0003] The overall structure of a high-pile wharf consists of a deck and a number of pile foundations located at the bottom of the deck. Among them, the pile foundation includes a distribution beam and a number of concrete piles connected to the bottom of the distribution beam. The concrete piles are all obliquely inserted into the underwater soil layer.
[0004] In the related art, when demolishing the pile foundation of a high-pile wharf, it is necessary to cut off the bottom end of the concrete pile and then lift it off together with the distribution beam. Since the concrete pile penetrates deep below the underwater soil layer, before cutting off the concrete pile, it is necessary to first clean the soil around the concrete pile, and then the bottom end of the concrete pile can be cut off by cutting equipment such as a wire saw.
[0005] Due to factors such as the small space between adjacent concrete piles and the position limitation of the distribution beam at the top of the concrete pile, the soil between the concrete piles cannot be excavated by large equipment. At present, it can only be manually cleaned by divers diving underwater. The cleaning workload is extremely large and the cleaning efficiency is extremely low. Therefore, there is room for improvement. Utility Model Content
[0006] In order to facilitate the cleaning of the soil between the concrete piles of a high-pile wharf, the present application provides a tool for removing the soil between inclined group piles.
[0007] A tool for removing the soil between inclined group piles provided by the present application adopts the following technical solutions:
[0008] A tool for removing the soil between inclined group piles includes a spiral drill and a material guiding casing. The material guiding casing is obliquely inserted into the soil layer between adjacent concrete piles, and the top end of the material guiding casing extends out of the water surface. The material guiding casing is used for the drill rod of the spiral drill to pass through.
[0009] By adopting the above technical solutions, when cleaning the soil between the concrete piles, the material guiding casing is inclined downward into the soil layer between adjacent concrete piles through a vibratory hammer, and then the drill rod of the spiral drill is moved into the material guiding casing. The drill rod is driven by the spiral drill to drill downward along the material guiding casing, and the soil in the material guiding casing at this time is taken out of the top end of the material guiding casing through the cooperation of the drill rod and the material guiding casing, realizing the rapid cleaning of most of the soil between the concrete piles. Compared with the traditional method of manually cleaning by divers diving underwater, the cleaning efficiency of the soil between the concrete piles is improved, and the cleaning difficulty of the soil between the concrete piles is reduced.
[0010] Preferably, the material guiding casing is assembled by a plurality of pipe sections, and adjacent pipe sections are connected by connecting pieces.
[0011] By adopting the above technical solution, the number of pipe sections can be increased or decreased according to actual construction needs to adjust the length of the material guiding casing, which is beneficial to improving the applicable range of the material guiding casing.
[0012] Preferably, one end of adjacent pipe sections close to each other is a splicing end, and the connecting piece includes an annular flange plate coaxially connected to the splicing end of the pipe section, and the annular flange plates at the splicing ends of adjacent pipe sections are connected by a plurality of bolts and nuts.
[0013] By adopting the above technical solution, on the one hand, reliable connection of adjacent pipe sections is realized, which is convenient for the assembly and connection of pipe sections. On the other hand, the overall strength of the splicing end of the pipe can be improved through the annular flange plate.
[0014] Preferably, a high-pressure water gun is also supported on the outer periphery of the top pipe of the material guiding casing, and the high-pressure water gun is arranged axially towards the material guiding casing.
[0015] By adopting the above technical solution, through the arrangement of the high-pressure water gun, when the drill rod is driven to drill downward along the material guiding casing by the auger drill later, the high-pressure water gun sprays high-pressure water towards the drill rod, and the high-pressure water sprayed by the high-pressure water gun blows the soil adhering to the drill rod blades off the blades of the drill rod to realize the cleaning of the drill rod.
[0016] Preferably, a high-pressure water pump is also supported on the outer periphery of the material guiding casing. The water inlet end and the water outlet end of the high-pressure water pump are respectively communicated with a water inlet pipe and a water outlet pipe, and the water outlet pipe is communicated with the high-pressure water gun.
[0017] By adopting the above technical solution, after the water outlet pipe is placed away from the high-pressure water pump into the water surface, the river water or seawater is pumped into the high-pressure water gun by the high-pressure water pump and then sprayed out through the high-pressure water gun, so as to directly use the seawater or river water as the water source of the high-pressure water gun, which is convenient for the high-pressure water gun to spray high-pressure water towards the drill rod to wash the drill rod.
[0018] Preferably, an annular plate is coaxially connected to the outer periphery of the top end of the material guiding casing, and the high-pressure water gun is supported on the annular plate.
[0019] By adopting the above technical solution, through the arrangement of the annular plate on the outer periphery of the top end of the material guiding casing, the overall strength of the top end of the material guiding casing can be improved through the annular plate, and further it is beneficial to reduce the deformation and damage of the top end of the material guiding casing when the material guiding casing is inserted and driven by a vibratory hammer.
[0020] Preferably, the end of the bottom end of the material guiding casing is sharp.
[0021] By adopting the above technical solution, when the vibrating hammer is used to insert and drive the material guiding casing subsequently, the bottom end of the material guiding casing is more likely to be driven into the soil layer between adjacent concrete piles.
[0022] Preferably, a plurality of lifting rings are further connected to the outer periphery of the top end of the material guiding casing.
[0023] By adopting the above technical solution, through the arrangement of a plurality of lifting rings, when the material guiding casing is lifted by a crane during transportation, the lifting appliance of the crane can be connected to the lifting rings to achieve a reliable connection between the crane and the material guiding casing, which is convenient for maintaining the stability and safety of the material guiding casing during the hoisting process.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. After the material guiding casing is inserted obliquely downward into the soil layer between the concrete piles, the drill rod of the auger drill is controlled to penetrate into the material guiding casing and drill obliquely downward along the material guiding casing. By using the cooperation between the material guiding casing and the auger drill, most of the soil between adjacent concrete piles can be exported outside the material guiding casing, which is beneficial to reducing the difficulty of cleaning the soil between the concrete piles.
[0026] 2. Since the material guiding casing is composed of a plurality of pipe sections, it is convenient to increase the number of pipe sections according to actual construction needs to adjust the length of the material guiding casing.
[0027] 3. Through the arrangement of the high-pressure water gun at the top end of the material guiding casing, when the drill rod of the auger drill subsequently drills along the material guiding casing to clean the soil between adjacent concrete piles, the high-pressure water gun can spray high-pressure water towards the drill rod to automatically clean the drill rod of the auger drill.

[0035] The following will further describe this application in detail with reference to the Figures 1-5 accompanying drawings.
[0036] The embodiment of this application discloses a tool for removing the soil between inclined group piles. Referring to Figure 1 and Figure 2 , it includes an auger drill 3 and a material guiding and protecting cylinder 2. The material guiding and protecting cylinder 2 is inserted obliquely downward into the soil layer between adjacent concrete piles 12, and the top end of the material guiding and protecting cylinder 2 extends out of the water surface. The material guiding and protecting cylinder 2 is used for the drill pipe of the auger drill 3 to pass through.
[0037] After the auger drill 3 controls the drill pipe to penetrate into the material guiding and protecting cylinder 2, the auger drill 3 drives the drill pipe to drill according to the material guiding and protecting cylinder 2, and then drills the soil between the piles located in the material guiding and protecting cylinder 2 at this time out to the material guiding and protecting cylinder 2; realizing the cleaning of most of the soil between adjacent concrete piles 12.
[0038] Referring to Figure 2 and Figure 3 , the material guiding and protecting cylinder 2 is composed of several pipe sections 21 spliced together. The adjacent pipe sections 21 are connected by connectors at the adjacent ends. The adjacent ends of the adjacent pipe sections 21 are splicing ends. The connector includes a flange plate 22 welded coaxially on the outer periphery of the splicing end of the pipe section 21; the flange plates 22 at the splicing ends of the adjacent pipe fittings are connected by a plurality of bolts and nuts. Through the above settings, the length of the material guiding and protecting cylinder 2 can be adjusted, which is convenient for adjusting the length of the material guiding and protecting cylinder 2 by increasing or decreasing the number of pipe sections 21 according to the actual construction needs during construction.
[0039] The bottom end of the material guiding and protecting cylinder 2 is set to be sharp. When the material guiding and protecting cylinder 2 is inserted by a vibratory hammer later, it is easier for the bottom end of the material guiding and protecting cylinder 2 to be inserted into the soil layer. An annular plate 23 is welded coaxially on the outer periphery of the top end of the material guiding and protecting cylinder 2, which is convenient for improving the overall strength of the top end of the material guiding and protecting cylinder 2 through the annular plate 23, and reducing the deformation and damage of the top end of the material guiding and protecting cylinder 2 when the material guiding and protecting cylinder 2 is inserted by a vibratory hammer later.
[0040] A plurality of suspension rings 24 are also welded and fixed at the top end of the material guiding and protecting cylinder 2, and the plurality of suspension rings 24 are evenly distributed around the axis of the material guiding and protecting cylinder 2. Through the arrangement of the plurality of suspension rings 24, when the material guiding and protecting cylinder 2 is lifted by a crane later, the crane lifting tool can be connected to the suspension rings 24 on the outer periphery of the material guiding and protecting cylinder 2 to realize the stable connection between the lifting tool and the material guiding and protecting cylinder 2, and thus is beneficial to maintaining the stability and safety of the material guiding and protecting cylinder 2 during the lifting process.
[0041] Referring toFigure 4 and Figure 5 Moreover, a high-pressure water gun 4 is also supported on the outer periphery of the top end of the material guiding casing 2. The high-pressure water gun 4 is fixed on the annular plate 23 through a hoop 41, and the high-pressure water gun 4 is arranged axially toward the material guiding casing 2. A high-pressure water pump 5 is further arranged on the outer periphery of the material guiding casing 2. The high-pressure water pump 5 is installed on the outer periphery of the material guiding casing 2 through a bracket 50. The water inlet end and the water outlet end of the high-pressure water pump 5 are respectively communicated with a water inlet pipe 51 and a water outlet pipe 52. One end of the water inlet pipe 51 away from the high-pressure water pump 5 extends to the bottom of the material guiding casing 2. One end of the water outlet pipe 52 away from the high-pressure water pump 5 is communicated with the high-pressure water pump 5.
[0042] With the above settings, while inserting and driving the material guiding casing 2, the end of the water inlet pipe 51 away from the water pump is immersed below the water surface. When the subsequent auger drill 3 controls the drill pipe to drill downward along the material guiding casing 2 to drill the soil between the concrete piles 12, seawater or river water is pumped into the high-pressure water gun 4 by the high-pressure water pump 5 and sprayed out through the high-pressure water gun 4. The high-pressure water gun 4 is used to spray the high-pressure water gun 4 toward the drill pipe to wash off the silt adhered between the drill pipe blades, so as to clean the drill pipe, reduce the adhesion of silt to the drill pipe, and prevent the situation that the silt adhered to the drill pipe falls during the subsequent transportation and movement of the auger drill 3, causing potential safety hazards.
[0043] The implementation principle of the embodiment of the present application is as follows: After the panel structure above the pile foundation to be demolished of the high-pile wharf 1 is demolished, the material guiding casing 2 is driven into the soil layer between the adjacent concrete piles 12 of the pile foundation to be demolished at the new front of the high-pile wharf 1 through a vibratory hammer. Then, the auger drill 3 is moved to the new front of the high-pile wharf 1 and the auger drill 3 is controlled to insert the drill pipe into the material guiding casing 2. Then, the auger drill 3 controls the drill pipe to drill downward along the material guiding casing 2 to drill the soil between the piles in the material guiding casing 2 out of the material guiding casing 2, so as to realize the cleaning of most of the soil between the adjacent concrete piles 12, which is beneficial to reducing the difficulty of cleaning the soil between the concrete piles 12. The setting of the material guiding casing 2 can cooperate with the drill pipe of the auger drill 3 to clean the soil between the concrete piles 12; on the other hand, the material guiding casing 2 can assist in limiting the drill pipe of the auger drill 3 to limit the situation that the drill pipe of the auger drill 3 shakes or deflects during the actual drilling process.
[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
