Abstract
Description
Technical Field
[0001] The invention relates to the technical field of foundation drainage, and in particular to an anti-blocking pile mouth structure, a drainage board inserting machine and a drainage board construction method. Background Art
[0002] At present, in the drainage treatment process of the foundation, it is often necessary to use a plate inserting machine to insert the drainage board into the soil layer. The general practice is to make the drainage board pass through a hollow pile pipe, and wrap the end of the drainage board around the pile shoe, and then use the pile pipe to press the pile shoe into the soil layer, so that the drainage board can be brought into the soil layer through the pile shoe; then the pile pipe is pulled out, and the part of the drainage board that has been inserted into the soil will remain in the soil layer under the action of the anchoring force of the soil, thereby playing a role in foundation drainage.
[0003] However, the current plate inserting machine has strict requirements on the address of the plate inserting operation. If complex geological conditions are encountered during the construction process, such as encountering sand layers or hard interlayers, it is easy to cause the pile hammer to vibrate for too long, and the ultra-soft silt and loose sand to liquefy and enter the pile pipe through the gap between the pile shoe and the pile pipe during vibration, causing the lower end of the pile pipe, that is, the pile mouth, to be blocked. On the one hand, the soil anchoring force on the drain board will be much smaller than the friction formed by the blockage inside the pile pipe, resulting in the soil being unable to retain the drain board or the length of the remaining drain board being limited, which in turn has a great negative impact on the construction quality and drainage effect of the drain board; on the other hand, it also causes the pile pipe to be cleaned of mud and sand every time the drain board is installed, which seriously slows down the construction efficiency of the drain board and reduces the construction speed. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that a plate inserting machine is prone to pipe blockage when inserting a drainage board, which, on the one hand, makes it difficult for the soil to retain the drainage board, thereby reducing the drainage effect; on the other hand, it is necessary to frequently clean the pile pipe, resulting in a decrease in construction efficiency and construction speed. An anti-blocking pile mouth structure, a drainage board inserting machine and a drainage board construction method are provided.
[0005] In a first aspect, the present invention provides an anti-blocking pile mouth structure, comprising:
[0006] Pile shoes, which are used to surround the drainage board;
[0007] A pile mouth, one end of which is used to connect with the pile pipe, and the other end of which is used to abut against the pile shoe; a first through groove is provided on the pile mouth, the width of which is smaller than the width of the pile shoe, and the drainage plate can pass through the first through groove;
[0008] A sealing structure is installed in the first through groove, and is used to form a seal between the drain plate and the inner wall of the first through groove.
[0009] The pile mouth and pile pipe can be independent components that are detachably connected or permanently connected, or they can be two parts of an integrated component; the drain board can pass through the first through groove, that is, the cross-sectional size of the first through groove is greater than or equal to the cross-sectional size of the drain board.
[0010] The anti-blocking pile mouth structure of the present scheme is provided with a sealing structure in the first through groove of the pile mouth. When the drain plate is arranged around the pile shoe through the first through groove, the sealing structure can form a seal between the drain plate and the first through groove, thereby isolating the space above and below the pile mouth and preventing mud and sand from entering the pile mouth and the pile pipe above the pile mouth. On the one hand, it can solve the blockage problem of the pile pipe, so that the operator does not need to clean the mud and sand from the pile pipe after each installation of the drain plate, thereby improving the construction efficiency and speed of installing the drain plate; on the other hand, it can avoid the problem that the soil anchoring force exerted on the drain plate is less than the friction force exerted on it by the blockage inside the pile pipe, thereby causing the soil to be difficult to retain the drain plate, thereby ensuring the construction quality and drainage effect of the drain plate; and in the process of pulling out the pile pipe, the sealing structure will be retained in the soil together with the drain plate, thereby providing a part of additional resistance for the drain plate, further improving the retention rate of the drain plate.
[0011] Preferably, a stop structure is further provided on the pile mouth, the stop structure is located on a side of the sealing structure away from the pile shoe, and the stop structure can abut against the sealing structure.
[0012] In this solution, a stop structure is arranged on the side of the sealing structure away from the pile shoe, which can prevent the sealing structure from moving away from the pile shoe during the installation of the drainage board, thereby preventing the sealing structure from escaping from the first through groove and causing sealing failure; at the same time, when the pile pipe is pulled out, it will not hinder the movement of the sealing structure from escaping from the first through groove together with the drainage board and remaining in the soil.
[0013] Preferably, the first through groove has a first chamfer at one end close to the pile shoe, and the width of the first chamfer at the end close to the pile shoe is greater than the width of the first chamfer at the end away from the pile shoe.
[0014] The specific structural forms of the first chamfer include but are not limited to chamfered square corners, chamfered round corners, and chamfered elliptical corners.
[0015] According to this solution, the width of the first through groove near one end of the pile shoe gradually increases in the direction close to the pile shoe. On the one hand, it can assist in the positioning of the pile shoe relative to the first through groove, so that the pile shoe can always remain at the end of the pile mouth during the installation of the drainage board; on the other hand, it can facilitate the cleaning of mud and sand inside the first through groove after the pile pipe is pulled out.
[0016] Preferably, the end of the first through groove away from the pile shoe has a second chamfer, and the width of the second chamfer away from the end of the pile shoe is greater than the width of the second chamfer close to the end of the pile shoe.
[0017] The specific structural forms of the second chamfer include but are not limited to chamfered square corners, chamfered round corners, and chamfered elliptical corners.
[0018] This solution makes the width of the first through groove gradually increase in the direction away from the pile shoe, that is, the width of the end close to the pile pipe gradually increases in the direction close to the pile pipe, which can provide guidance for the drain board and facilitate the operator to pass the drain board through the first through groove more quickly.
[0019] Preferably, it also comprises a connecting rope, one end of which is connected to the pile shoe, and the other end of which is connected to the pile mouth or used to connect to the pile pipe.
[0020] In this solution, a connecting rope is arranged on the pile mouth for connecting the pile shoe. When the pile mouth is pulled out together with the pile pipe, the pile shoe can be pulled out from the soil together with the connecting rope, thereby realizing the reuse of the pile shoe.
[0021] Preferably, the connecting rope includes any one of a chain and a wire rope.
[0022] This proposal recommends the specific form of connecting rope, chain and wire rope with good weather resistance to ensure a long service life.
[0023] Preferably, the sealing structure is a rubber component.
[0024] This proposal recommends the material of the sealing structure.
[0025] Preferably, the outer dimension of the end of the pile mouth close to the pile shoe is smaller than the outer dimension of the end of the pile mouth away from the pile shoe.
[0026] This proposal recommends a specific shape of the pile mouth, so that the pile mouth is larger at the top and smaller at the bottom when connected to the pile pipe, and can be more easily pressed into the soil.
[0027] In a second aspect, the present invention provides a drainage board inserting machine, comprising:
[0028] Pile pipe;
[0029] A pile shoe is arranged at one end of the pile pipe and is used to surround the drainage board; an anti-blocking pile mouth structure of the present invention is arranged between the pile shoe and the pile pipe.
[0030] The anti-blocking pile mouth structure of the present scheme adopts an anti-blocking pile mouth structure of the present invention, so it is not easy to get blocked during the process of injecting the drainage pipe, and it can ensure that the drainage board is more easily retained in the soil, thereby ensuring the construction quality and drainage effect of the drainage board; at the same time, there is no need to carry out mud and sand cleaning operations after each injection operation, and it has higher construction efficiency and construction speed.
[0031] In a third aspect, the present invention provides a drainage board construction method, comprising the following steps:
[0032] S1. Connect an anti-blocking pile nozzle structure of the present invention to a pile pipe; insert a drain plate into the pile pipe until the drain plate passes through the first through groove and the sealing structure;
[0033] S2, placing the pile shoe against the end of the pile mouth away from the pile pipe, and wrapping the end of the drainage board away from the pile pipe around the pile shoe;
[0034] S3, pressing the pile pipe into the ground until it reaches a specified depth; pulling out the pile pipe, and disconnecting the drain board from the portion of the drain board exposed above the ground;
[0035] S4. Repeat steps S2 to S3 until the drainage board installation operation is completed at all predetermined board positions.
[0036] When step S2 is repeated after the pile pipe is pulled out in step S3, if the pile shoe is a disposable type, a new pile shoe needs to be abutted against the pile mouth; if the pile shoe is a reusable type, the position of the pile shoe can be rearranged.
[0037] The drainage board construction method of the present invention uses an anti-blocking pile mouth structure of the present invention, which can prevent mud and sand from entering the pile mouth and the pile pipe above the pile mouth when the drainage board is installed, thereby avoiding pipe blockage; therefore, the present invention does not need to frequently clean the pile pipe like the prior art, has higher operating efficiency and operating speed, and can improve the drainage board's retention rate and drainage effect.

On the one hand, it can solve the problem of pile pipe blockage, so that operators do not need to clean the pile pipe with mud and sand after each installation of the drain plate, thereby improving the construction efficiency and speed of installing the drain plate; on the other hand, it can avoid the problem that the soil anchoring force exerted on the drain plate is less than the friction force exerted on it by the blockage inside the pile pipe, thereby causing the soil to be difficult to retain the drain plate, thereby ensuring the construction quality and drainage effect of the drain plate; and in the process of pulling out the pile pipe, the sealing structure will be retained in the soil together with the drain plate, thereby providing a part of additional resistance for the drain plate, further improving the retention rate of the drain plate.

[0055] like Figures 1 to 4 As shown, an anti-blocking pile mouth structure comprises a pile mouth 2 and a sealing structure 3. One end of the pile mouth 2 is used to connect with the pile pipe 6, and the other end of the pile mouth 2 is used to abut against the pile shoe 1; a first through groove 21 is provided on the pile mouth 2, and the width of the first through groove 21 is greater than or equal to twice the width of the drain plate 7 and less than the width of the pile shoe 1; the sealing structure 3 is installed in the first through groove 21, and the sealing structure 3 is used to form a seal between the drain plate 7 and the inner wall of the first through groove 21.
[0056] In order to more clearly show the relationship between the pile mouth 2 and the pile shoe 1, as shown in Figure 5 The pile shoe 1 used as an example in the present embodiment is shown, and the pile shoe 1 comprises a cylindrical pile shoe body 11, and a winding structure 12 which is roughly Π-shaped and rotated 90° counterclockwise; correspondingly, the pile mouth 2 of the present embodiment is a mixed cross-section structure, the upper part of which is used to connect with the pile pipe 6, so the cross-sectional shape is a circle adapted to the pile pipe 6; and the lower part is used to abut with the long strip pile shoe body 11, so the cross-sectional shape is a long strip matching the pile shoe body 11; the first through groove 21 is arranged in the middle of the pile mouth 2, and its cross-sectional shape and size are adapted to the drainage board 7 on the one hand, so that the drainage board 7 can pass through the first through groove 21 to reach the pile shoe 1, and on the other hand, it is smaller than the pile shoe body 11, so that the pile shoe body 11 can cover the first through groove 21 as completely as possible, and avoid mud and sand from entering the first through groove 21 as much as possible.
[0057] In an optional embodiment, the end of the first through groove 21 close to the pile shoe 1 has a first chamfer 211, and the width of the first chamfer 211 close to the pile shoe 1 is greater than the width of the first chamfer 211 away from the pile shoe 1. Figure 2 As shown, the first chamfer 211 makes the bottom of the first through groove 21 roughly in an inverted V shape, which can better limit the pile shoe 1 on the one hand, and also facilitate the cleaning of mud and sand in the first through groove 21 on the other hand.
[0058] In an optional embodiment, the end of the first through groove 21 away from the pile shoe 1 has a second chamfer 212, and the width of the second chamfer 212 away from the pile shoe 1 is greater than the width of the second chamfer 212 close to the pile shoe 1.

[0059] In an optional embodiment, a stopper structure 4 is further provided on the pile mouth 2, and the stopper structure 4 is located on a side of the sealing structure 3 away from the pile shoe 1, and the stopper structure 4 can abut against the sealing structure 3. Figure 2 As shown, the stop structure 4 is disposed in the first through groove 21 at a position close to the second chamfer 212 , and is used to prevent the sealing structure 3 from moving upward, but will not prevent the sealing structure 3 from moving downward.
[0060] In an optional embodiment, if Figure 3 As shown, it also includes a connecting rope 5, one end of the connecting rope 5 is connected to the pile shoe 1, and the other end of the connecting rope 5 is connected to the pile mouth 2 or is used to connect the pile pipe 6.
[0061] In an optional implementation manner, the connecting rope 5 comprises any one of a chain and a steel wire rope. In this embodiment, a chain formed by connecting steel rings in series is specifically used.
[0062] In an optional implementation manner, the sealing structure 3 is a rubber material component. In this embodiment, the sealing structure 3 is specifically made of silicone material.
[0063] In an optional embodiment, the height of the sealing structure 3, i.e. Figure 2 The dimension in the middle and upper directions is greater than or equal to five times the thickness of the drain board 7, and less than or equal to 12 times the thickness of the drain board 7, so as to avoid the situation where the sealing structure 3 is too thick, making it difficult for the drain board 7 to pass through, or too thin, resulting in insufficient sealing effect.
[0064] In an optional embodiment, the outer dimension of the end of the pile mouth 2 close to the pile shoe 1 is smaller than the outer dimension of the end of the pile mouth 2 away from the pile shoe 1. Figures 1 to 3 As shown, the pile mouth 2 of this embodiment is larger at the top and smaller at the bottom.
[0065] Example 2
[0066] A drainage board inserting machine comprises a pile pipe 6 and a pile shoe 1; the pile shoe 1 is arranged at one end of the pile pipe 6, and the pile shoe 1 is used to surround the drainage board 7; an anti-blocking pile mouth structure in Example 1 is arranged between the pile shoe 1 and the pile pipe 6.
[0067] In an optional embodiment, the cross-section of the end of the pile shoe 1 away from the pile mouth 2 is arc-shaped or V-shaped. Figure 1 to Figure 2 As shown, the pile shoe 1 of this embodiment includes a pile shoe body 11 with a circular cross section, which can be more easily pressed into the soil; correspondingly, at the end of the pile mouth 2 away from the pile pipe 6, that is, the pile mouth 2 is Figure 3 A circular arc groove is also provided at the lower end, and the shape and size of the circular arc groove correspond to the shape and size of the pile shoe body 11, so that the pile shoe body 11 can be more firmly abutted against the pile mouth 2 and is not easily separated from the pile mouth 2 during the process of pressing down the pile pipe 6.
[0068] Example 3
[0069] A drainage board construction method comprises the following steps:
[0070] S1, connecting an anti-blocking pile nozzle 2 structure in Example 1 to a pile pipe 6; inserting a drainage board 7 into the pile pipe 6 until the drainage board 7 passes through the first through groove 21 and the sealing structure 3;
[0071] S2, the pile shoe 1 is brought into contact with the end of the pile mouth 2 away from the pile pipe 6, and the end of the drain plate 7 away from the pile pipe 6 is wound around the pile shoe 1;
[0072] S3, pressing the pile pipe 6 into the ground until it reaches a specified depth; pulling out the pile pipe 6, and disconnecting the drain board 7 from the portion of the drain board 7 exposed to the ground;
[0073] S4, repeating steps S2 to S3 until the drainage boards 7 at all predetermined board positions are installed.
[0074] In an optional embodiment, in step S1, the drain board 7 can be inserted into the pile pipe 6 from the end of the pile pipe 6 away from the pile mouth 2, and the drain board 7 can be pushed or pulled to move toward the pile mouth 2; due to the guidance of the second chamfer 212, the drain board 7 will naturally enter the first through groove 21, and continuing to push and pull the drain board 7 can make the drain board 7 pass through the first through groove 21 and the sealing structure 3.
[0075] In an optional embodiment, in step S2, the end of the drain plate 7 away from the pile pipe 6 can be folded toward the pile pipe 6 to form a lasso-like structure, and then the winding structure 12 of the pile shoe 1 is passed through the lasso-like structure to avoid the space between the pile shoe 1 and the pile mouth 2 being too narrow after the pile shoe 1 is connected, thereby preventing the winding operation of the drain plate 7 from being hindered. After completing this step, the relative position relationship of the pile pipe 6, the pile mouth 2, the pile shoe 1, and the drain plate 7 is as follows: Figure 1 shown.
[0076] In an optional embodiment, in step S3, if a connecting rope 5 is connected between the pile mouth 2 and the pile shoe 1, when the pile pipe 6 and the pile mouth 2 are lifted, the pile shoe 1 will first tilt under the traction of the connecting rope 5, so that the winding structure 12 is separated from the lasso-shaped drainage board 7, and then pulled out of the ground together with the pile pipe 6 and the pile mouth 2 under the traction of the connecting rope 5. Therefore, if step S2 is to be repeated, the drainage board 7 is re-wound around the winding structure 12, and the pile shoe body 11 is abutted against the pile mouth 2.
