Description

Technical Field

[0001] The invention discloses a casting casing for the exposed section of an anchor-pull anti-slide pile, which is used for casting the exposed section of the anchor-pull anti-slide pile and belongs to the technical field of casings. Background Art

[0002] Anchor-type anti-slide piles are a type of slope support structure. Their primary function is to resist lateral pressure on the soil to prevent collapse and slippage. This is achieved by driving prestressed anchor rods (cables) into the pile waist. This type of structure is known as pile-anchor support. Anchor-type anti-slide piles are commonly used to address shallow and medium-thick landslides and are a primary anti-slide measure.

[0003] Specifically, anti-slide piles are piles that penetrate the landslide body and extend deep into the sliding bed. They are used to support the sliding force of the sliding body and stabilize the slope. Anchor piles, on the other hand, have prestressed anchor rods (cables) driven into the pile ends. If anchor rods (cables) are not required, they are called cantilever piles. The main difference between anti-slide piles and anchor piles lies in whether or not prestressed anchor rods (cables) are used.

[0004] After drilling, a casing needs to be set on the drill hole to cast and support the exposed section of the anchor-pull anti-slip pile. Since the anti-slip pile has a long length, such as 20m, a large diameter, such as 2.2m, and a long exposed section, such as 10m, and the anti-slip pile has high requirements for its casting, the casing used to support the exposed section is also required to be high. However, the casting casing used in the existing technology has the following technical problems:

[0005] 1. The casing is placed directly on the surface of the borehole, which makes it difficult to accurately position it. This can easily cause the axis of the buried section and the exposed section to deviate, affecting the structural performance of the anti-slip pile.

[0006] 2. The casing is inserted into the top of the borehole at one end, which can easily cause the diameter of the top section into the soil to become smaller, which will also affect the structural performance of the anti-slip pile and easily make it difficult to remove the casing later. Utility Model Content

[0007] The purpose of the utility model is to provide a cast casing for the exposed section of an anchor-pull anti-slip pile, which solves the problem in the prior art that the casing is directly placed on the surface of the drill hole, which is difficult to accurately position, and thus easily causes the axis of the buried section and the exposed section to be offset, affecting the structural performance of the anti-slip pile; or the casing is inserted into the top of the drill hole at one end, which easily causes the diameter of the buried top section to become smaller, which also affects the structural performance of the anti-slip pile and easily makes it difficult to remove the casing later.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A casting casing for the exposed section of an anchor-pull anti-slip pile comprises a supporting structure arranged at a drill hole, a positioning structure arranged to cooperate with the supporting structure and the center of the drill hole or housed in the supporting structure, and a cylindrical structure movably coordinated with the supporting structure.

[0010] Further, the support structure includes two support frames arranged on opposite sides of the borehole;

[0011] The support frame includes a bottom support frame, an upper support frame arranged on the bottom support frame, and an arc-shaped limiting structure arranged on the bottom support frame and the upper support frame to longitudinally limit the cylindrical structure;

[0012] The bottom support frame is provided with a plurality of fixing blocks with holes, and cone rods which cooperate with the fixing blocks to fix the support frame on the ground.

[0013] Furthermore, the arc-shaped limiting structure includes a plurality of limiting members;

[0014] The limiting member includes a plurality of connecting members connected to the bottom support frame or the upper support frame, and an arc-shaped member connected to the connecting members, which has an arc surface smaller than the semicircular structure and limits the longitudinal position of the cylinder.

[0015] Furthermore, the positioning structure includes a T-shaped slot provided on the bottom support frame and open at the top and one side of the arc-shaped member, a T-shaped member slidably provided on the T-shaped slot, a screw provided on the T-shaped member and slidingly engaged with the T-shaped slot, and a nut provided on the screw, the T-shaped member including a horizontal plate located at one end of the arc-shaped member, a vertical plate connected to the horizontal plate and slidingly engaged with the T-shaped slot, and the screw provided on the vertical plate on the opposite side of the horizontal plate;

[0016] Located at the top opening side of the T-slot and / or one side of the arc-shaped member, a positioning line corresponding to the center of the arc-shaped member is provided on the horizontal plate.

[0017] Furthermore, the T-slot is provided with a scale;

[0018] The top of the screw is provided with a pointer line matched with the scale.

[0019] Furthermore, the cylindrical structure includes two matching semicircular cylindrical structures, each of which includes a semicircular cylindrical body, connecting blocks provided on both sides of the semicircular cylindrical body, through holes provided on the connecting blocks, and bolts and nuts matching the through holes to fix the two semicircular cylindrical structures.

[0020] After the two supporting frames are fixed, the distance formed by the arc-shaped pieces thereon can allow the connecting block to slide downward.

[0021] Furthermore, rubber pads are provided on the mating sides of adjacent connecting blocks.

[0022] Furthermore, when the semicircular cylinder in the semicircular cylinder structure has more than two sections, the multiple sections of the semicircular cylinder and the connecting block with through holes are fixed by connecting plates with mounting holes at the ends, and bolts and nuts, and the support frame cooperates with the bottom section of the semicircular cylinder and the connecting block.

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] First, the present invention provides a positioning structure on the support structure, which can first be positioned with the positioning structure and the center of the drill hole, and then the support structure is fixed to the ground based on the positioned positioning structure, and then the cylindrical structure is hoisted in the support structure so that its bottom contacts the ground surface at the edge of the drill hole, so that the center of the cylindrical structure can be quickly and accurately positioned and is located on the same axis as the center of the drill hole, thereby avoiding the problem of axial deviation between the buried section and the exposed section, ensuring the structural performance of the anti-slip pile, and at the same time avoiding the problem of the diameter of the buried top section becoming smaller due to the insertion of the casing into the top of the drill hole, ensuring the uniformity of the overall diameter of the anti-slip pile, improving the structural stability, and adopting this structure, it is also easy to dismantle later;

[0025] Second, the support structure of the present invention includes support frames and arc-shaped limiting structures arranged on opposite sides of the drill hole. The support frames are firmly fixed to the ground by passing the cone rod through the hole on the fixing block to support the cylinder structure, effectively improving the overall stability of the cylinder structure. The bottom support frame and the upper support frame can evenly distribute the weight from the cylinder structure and concrete, reduce the pressure on the soil around the drill hole, and reduce the risk of soil deformation. The arc-shaped limiting structure can limit the cylinder structure in the longitudinal direction (even if the central axis of the cylinder structure and the center of the drill hole are on the same axis), ensuring that the position of the casing in the vertical direction is fixed, thereby ensuring the accuracy of pouring;

[0026] 3. The arc-shaped limiting structure of the utility model is provided with a plurality of limiting members on the support frame, and the arc-shaped members among the limiting members cooperate with the cylindrical structure. The cylindrical structure can be supported by the support frame supporting the arc-shaped members, that is, the weight of the cylindrical structure and the pressure during concrete pouring can be evenly distributed on the support frame, thereby reducing local stress concentration, reducing deviation, and improving the stability of the overall structure.

[0027] Fourth, the positioning structure of the utility model, after the instrument locates the center of the drill hole, moves the T-shaped pieces on the two support frames by the screw to slide the same distance in the T-slot, and makes the cross plates in the T-shaped pieces on the two support frames contact each other, and the gap line and positioning line formed by the contact correspond to the cross-shaped positioning line emitted by the instrument, so as to realize the positioning of the support frame, and fix the T-shaped piece in the T-slot by the nut and the screw to realize the positioning of the support frame, and position and fix the support frame, so as to realize the accurate positioning of the support frame quickly, and after fixing, move the T-shaped piece and hoist the cylinder structure into the two support frames, which can ensure that the cylinder structure is consistent with the center line of the drill hole, and effectively reduce the eccentricity error;

[0028] 5. The utility model sets a scale on the T-slot and a pointer line matching the scale on the top of the screw. Construction workers can intuitively read and adjust the position of the T-piece, thereby improving the alignment accuracy of the casing and the center line of the drill hole;

[0029] 6. The cylindrical structure of the present invention is easy to install and disassemble in narrow or difficult-to-operate spaces;

[0030] 7. The utility model provides rubber pads on the connecting blocks to fill the small gaps between the connecting blocks, preventing concrete from leaking during pouring and maintaining the integrity of the pouring;

[0031] 8. When the semicircular cylinder in the semicircular cylinder structure of the present invention is multi-section, modular construction is achieved, which is convenient for rapid assembly and adjustment according to the requirements of drilling holes of different depths, and also overcomes the problem of difficult lifting.

[0044] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0045] Example 1

[0046] In order to solve the problem that the casing is placed directly on the surface of the borehole in the prior art, which is difficult to accurately position, thus easily causing the axis of the buried section and the exposed section to deviate, affecting the structural performance of the anti-slip pile; or the casing is inserted into the top of the borehole at one end, which easily causes the diameter of the buried top section to become smaller, also affecting the structural performance of the anti-slip pile and making it difficult to remove the casing later. Figure 1-4 As shown, a cast casing for the exposed section of an anchor-pull anti-sliding pile is provided, comprising a support structure 1 arranged at the drill hole, a positioning structure 2 arranged on the support structure 1 and matched with the center of the drill hole or housed in the support structure 1, and a cylindrical structure 3 that movably cooperates with the support structure 1.

[0047] In practice, the support structure and the borehole are first positioned by the positioning structure 2 on the support structure 1. After positioning, the support structure 1 is fixed, and the cylindrical structure is hoisted into the support structure. The cylindrical structure is supported and cast by the support structure 1. In this embodiment, by setting a positioning structure on the support structure, the positioning structure and the center of the borehole can be first positioned, and the support structure is fixed to the ground based on the positioned positioning structure. The cylindrical structure is then hoisted into the support structure so that its bottom contacts the ground surface at the edge of the borehole, so that the center of the cylindrical structure can be quickly and accurately positioned and is located on the same axis as the center of the borehole, thereby avoiding the problem of axial offset between the buried section and the exposed section, ensuring the structural performance of the anti-slip pile, and at the same time avoiding the problem of the diameter of the buried top section becoming smaller due to the insertion of the casing into the top of the borehole, ensuring the uniformity of the overall diameter of the anti-slip pile, improving the structural stability, and adopting this structure, which is also easy to dismantle later.

[0048] Example 2

[0049] Based on Example 1, the support structure 1 includes two support frames 4 arranged on opposite sides of the borehole; the support frames 4 include a bottom support frame 5, an upper support frame 6 arranged on the bottom support frame 5, and an arc-shaped limiting structure 7 arranged on the bottom support frame 5 and the upper support frame 6 to longitudinally limit the cylindrical structure 3; the bottom support frame 5 is provided with a plurality of fixed blocks 11 with holes, and a tapered rod 12 that cooperates with the fixed blocks 11 to fix the support frames 4 to the ground. The two support frames 4 can be independent of each other, or they can be fixed with connecting parts, such as fasteners (including fasteners and snap fasteners that cooperate with the fasteners) or threaded connectors (including screws provided on the support frames, connecting plates and nuts that cooperate with the screws). In practice, the appropriate one is selected according to actual needs to better fix or support the cylindrical structure. For example, when working on a slope, the latter can be selected so that the support frames can be evenly stressed.

[0050] In practice, after the positioning structure is positioned, the support frame is firmly fixed to the ground by passing the tapered rod through the hole on the fixed block to support the cylinder structure, effectively improving the overall stability of the cylinder structure. The bottom support frame and the upper support frame can evenly distribute the weight from the cylinder structure and concrete, reduce the pressure on the soil around the borehole, and reduce the risk of soil deformation. The arc-shaped limiting structure can limit the longitudinal position of the cylinder structure (even if the center axis of the cylinder structure and the center of the borehole are on the same axis), ensuring that the casing is fixed in the vertical direction, thereby ensuring the accuracy of pouring.

[0051] Example 3

[0052] On the basis of Example 2, the arc-shaped limiting structure 7 includes a plurality of limiting members 8; the limiting members 8 include a plurality of connecting members 9 connected to the bottom support frame 5 or the upper support frame 6, and an arc-shaped member 10 connected to the connecting member 9, with an arc surface smaller than the semicircular structure and for longitudinally limiting the cylinder. The arc-shaped limiting structure is able to support the cylinder structure by supporting the arc-shaped member through the support frame by arranging a plurality of limiting members on the support frame, and the arc-shaped member in the limiting member cooperates with the cylinder structure, that is, the weight of the cylinder structure and the pressure during concrete pouring can be evenly distributed to the support frame, thereby reducing local stress concentration, reducing offset, and improving the stability of the overall structure. The arc-shaped member 10 is limited to have an arc surface smaller than the semicircular structure. The purpose is to take into account that the semicircular cylinder 22 in the subsequent cylinder structure is connected by a connecting block. When the cylinder structure 3 is hoisted into the arc-shaped member 10 in the two support frames, it is necessary to ensure that the connecting block can pass through to prevent it from being unable to be hoisted in.

[0053] Example 4

[0054] On the basis of Example 2, the positioning structure 2 includes a T-slot 13 arranged on the bottom support frame and open at the top and one side of the arc-shaped member 10, a T-piece 14 slidably arranged on the T-slot 13, a screw 15 arranged on the T-piece 14 and slidingly matched with the T-slot 13, and a nut arranged on the screw 15. The T-piece 14 includes a horizontal plate 16 located at one end of the arc-shaped member 10, a vertical plate 17 connected to the horizontal plate 16 and slidingly matched with the T-slot 13, and the screw 15 is arranged on the vertical plate 17 on the opposite side of the horizontal plate 16; a positioning line 18 corresponding to the center of the arc-shaped member 10 is provided on the horizontal plate 16 located on the top open side of the T-slot 13 or / and one side of the arc-shaped member.

[0055] In practice, after the positioning structure has located the center of the borehole by the instrument, that is, the instrument (such as a total station or other positioning instrument) forms a cross-shaped positioning line to locate the center of the borehole, the T-shaped pieces on the two support frames are moved by the screw to slide the same distance in the corresponding T-slots, and the cross plates in the T-shaped pieces on the two support frames are brought into contact with each other. The gap line and positioning line formed by the contact correspond to the cross-shaped positioning line emitted by the instrument to achieve the positioning of the support frame, and the T-shaped piece is fixed in the T-slot by the nut and the screw to achieve the positioning of the support frame, and the support frame is positioned and fixed, so as to quickly achieve accurate positioning of the support frame. After fixing, the T-shaped piece is moved to the support frame, and the cylindrical structure is hoisted into the two support frames, which can ensure that the cylindrical structure is consistent with the center line of the borehole, effectively reducing the eccentricity error.

[0056] Example 5

[0057] Based on Example 4, the T-slot 13 is provided with a scale 19, and the top of the screw 15 is provided with a pointer line 20 that matches the scale 19. The scale on the T-slot and the pointer line on the top of the screw that matches the scale allow construction workers to intuitively read and adjust the position of the T-piece, thereby improving the alignment accuracy of the casing with the centerline of the drill hole.

[0058] Example 6

[0059] On the basis of Example 5, the cylindrical structure 3 includes two matching semicircular cylindrical structures 21, and the semicircular cylindrical structure 21 includes a semicircular cylinder 22, connecting blocks 23 provided on both sides of the semicircular cylinder 22, through holes 24 provided on the connecting blocks 23, and bolts and nuts that cooperate with the through holes 24 to fix the two semicircular cylindrical structures 21; after the two support frames 4 are fixed, the spacing formed by the arc-shaped members 10 thereon can allow the connecting blocks 23 to slide downward. The cylindrical structure in this embodiment is convenient for installation and disassembly in narrow or difficult-to-operate spaces. When the semicircular cylinder 22 in the semicircular cylindrical structure 21 has more than two sections, the multiple sections of the semicircular cylinder 22 and the connecting blocks 23 with through holes 24 are fixed by connecting pieces with mounting holes at the ends in cooperation with bolts and nuts, and the support frame 4 cooperates with the bottom section of the semicircular cylinder 22 and the connecting blocks 23. When the semicircular cylinder in the semicircular cylinder structure is multi-section, modular construction is achieved, which is convenient for rapid assembly and adjustment according to the drilling requirements of different depths, and also overcomes the problem of difficult lifting.

[0060] Example 7

[0061] On the basis of Example 6, the adjacent connecting blocks 23 are matched with each other, and rubber pads 25 are provided on the connecting blocks 23. The rubber pads provided on the connecting blocks can fill the small gaps between the connecting blocks, prevent the concrete from leaking during the pouring process, and maintain the integrity of the pouring.
