Description

Technical Field

[0001] This utility model relates to the field of pile hole construction technology, and in particular to a retaining structure for pile hole construction. Background Technology

[0002] Pile holes refer to the holes made in building construction to establish pile foundations. Common types of pile holes include: cast-in-place piles, manually excavated cast-in-place piles, and pile pilot holes.

[0003] After drilling is completed, construction workers need to proceed to the next borehole. Therefore, safety protection is required for completed pile holes. For example, Chinese utility model patent CN217760188U discloses a safety protection device for the borehole opening of a drilled pile foundation. This device includes an outer protective mechanism fitted onto the borehole casing and a protective mesh frame that works in conjunction with the outer protective mechanism to protect the borehole opening of the casing. The outer protective mechanism includes four legs arranged in an array. The tops of the four legs are connected sequentially by four square steel bars to form a closed square steel frame, and the middle sections of the four legs are connected sequentially by four casing protective steel bars to form a closed casing protective frame. The bottom of the outer protective mechanism is fitted onto the borehole casing, and three protective railings are installed on the top of the outer protective mechanism to provide safety protection for the completed pile hole opening and reduce personnel safety risks.

[0004] However, the height of the protective device in the above application is relatively fixed during use, while the height of the steel casing of the pile hole above the ground is not fixed. This means that the support height of the protective device needs to be made according to the height of the steel casing above the ground on site, which increases the cost of use. Moreover, when the distance between the entire protective device and the steel casing is too large, there is still a safety hazard, which affects the protective effect. Therefore, a retaining structure for pile hole construction is proposed to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes a retaining structure for pile hole construction. By using an adjusting component in conjunction with a support rod, the height of the entire retaining structure can be adjusted to reduce the gap between the entire retaining structure and the pile hole, thereby improving the protective effect.

[0007] (II) Technical Solution

[0008] This utility model provides a retaining structure for pile hole construction, including a support ring and a support frame installed inside the support ring, wherein a wire mesh is fixedly connected between the inner side of the support ring and the support frame.

[0009] Two sets of mounting blocks are fixedly connected to the outer surface of the support ring, and a support rod that passes through the mounting block is slidably connected to each mounting block. The support frame is cross-shaped, and several telescopic rods are installed below the support ring.

[0010] The support frame is equipped with an adjusting component for raising and lowering the support ring;

[0011] The adjusting component includes a rotating rod rotatably connected to the center of the support frame, a connecting ring fixedly connected to the outer side of the rotating rod, two sets of support blocks fixedly connected to the upper surface of the support frame, and a limiting rod extending into the support rod at one end slidably connected to the middle of each support block, a retaining ring fixedly connected to each limiting rod, and a connecting spring fixedly connected between each retaining ring and the support block, and a pull rod hinged to the end of each limiting rod away from the support rod, with one end hinged to the connecting ring.

[0012] The lower surface of the support frame is provided with an installation groove, and a support member for supporting and limiting the support ring to the pile hole is provided in the installation groove.

[0013] Preferably, a plurality of the telescopic rods are distributed in a ring at equal intervals below the support ring, and the plurality of telescopic rods are fitted together. Each telescopic rod consists of a sleeve rod and a vertical rod. The vertical rod is fixedly connected to the support ring, and the sleeve rod is slidably connected to the vertical rod. The end of the vertical rod located inside the sleeve rod is T-shaped.

[0014] Preferably, the two sets of mounting blocks are symmetrically distributed in a cross shape, and the distribution orientation of the mounting blocks is adapted to the distribution orientation of the support blocks on the support frame.

[0015] Preferably, the support rod has a plurality of equally spaced limiting grooves on the side facing the limiting rod, and the specifications of the limiting grooves are adapted to the specifications of the limiting rod.

[0016] Preferably, the support includes a crossbar fixedly connected in the mounting groove, a sliding block slidably connected to the crossbar, a support spring fixedly connected between the sliding block and the inner side of the mounting groove, and a stop plate fixedly connected to the lower end of the sliding block.

[0017] Preferably, the mounting groove and crossbar are symmetrically distributed in a cross shape, similar to the support frame. The lower end of the abutment is inclined, narrower at the bottom and wider at the top, and the side of the abutment closest to the mounting block is serrated.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0019] 1. The retaining structure for pile hole construction uses adjustable components to raise and lower the mounting blocks and support rings on the support rods. This allows the raised and lowered support rings to drive the brackets and wire mesh to fit tightly against the steel casing on the pile hole, thereby improving the retaining effect. At the same time, several telescopic rods on the support rings can form a double-layer retaining measure with the steel casing to further improve the retaining effect. The telescopic rods on the support rings also allow the entire retaining structure to adapt to the maintenance of pile holes without steel casings, thereby improving the adaptability of the retaining structure.

[0020] 2. The retaining structure for pile hole construction uses a support plate located below the support frame. Due to the elastic support of the sliding block and the support spring, the support plate can be squeezed into the steel casing or the hole wall during placement, thus providing stable support for the entire retaining structure and improving the stability of the entire retaining structure during placement.

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-4 As shown, the present invention proposes a retaining structure for pile hole construction, including a support ring 1 and a support frame 2 installed inside the support ring 1, with a wire mesh 3 fixedly connected between the inner sides of the support ring 1 and the support frame 2.

[0030] Two sets of mounting blocks 5 are fixedly connected to the outer surface of the support ring 1, and a support rod 6 that passes through the mounting block 5 is slidably connected to each mounting block 5. The support frame 2 is cross-shaped.

[0031] The support frame 2 is equipped with an adjusting component 4 for raising and lowering the support ring 1;

[0032] The lower surface of the support frame 2 is provided with an installation groove 8, and a support member 9 for supporting and limiting the support ring 1 to the pile hole is provided in the installation groove 8.

[0033] In this invention, the height of the entire enclosure structure can be adjusted by adjusting the adjusting component 4 in conjunction with the support rod 6, so as to reduce the gap between the entire enclosure structure and the pile hole. The support component 9 can provide support for the support ring 1, the support frame 2 and the wire mesh 3 to improve the stability of the placement.

[0034] In an optional embodiment, the adjusting member 4 includes a rotating rod 41 rotatably connected to the center of the support frame 2, a connecting ring 42 fixedly connected to the outer side of the rotating rod 41, two sets of support blocks 43 fixedly connected to the upper surface of the support frame 2, and a limiting rod 44 extending into the support rod 6 at one end slidably connected to the middle of each support block 43, a retaining ring 45 fixedly connected to each limiting rod 44, and a connecting spring 46 fixedly connected between each retaining ring 45 and the support block 43, and a pull rod 47 hinged to one end of each limiting rod 44 away from the support rod 6.

[0035] In this embodiment, the mounting block 5 and the support ring 1 on the support rod 6 are raised and lowered by the adjusting component 4, so that the raised and lowered support ring 1 drives the bracket 2 and the wire mesh 3 to fit tightly with the steel casing on the pile hole, thereby improving the enclosure effect. At the same time, several telescopic rods 7 on the support ring 1 can form a double-layer enclosure with the steel casing to further improve the enclosure effect. The several telescopic rods 7 on the support ring 1 can also make the entire enclosure structure adaptable to the maintenance of pile holes without steel casing, thereby improving the adaptability of the enclosure structure.

[0036] It should be noted that several telescopic rods 7 are installed below the support ring 1. The telescopic rods 7 are distributed in a ring at equal intervals below the support ring 1, and the telescopic rods 7 fit together with each other. Each telescopic rod 7 consists of a sleeve rod and a vertical rod. The vertical rod is fixedly connected to the support ring 1, and the sleeve rod is slidably connected to the vertical rod. The end of the vertical rod located inside the sleeve rod is T-shaped, so that the telescopic rods 7 are distributed below the support ring 1 and form a ring. This can cooperate with the support ring 1, support frame 2 and wire mesh 3 to replace the steel casing in the process of protecting the pile hole without steel casing. It can also protect the outer surface of the pile hole opening. At the same time, the telescopic rods 7 can contract when squeezed to fit the uneven ground at the pile hole opening.

[0037] The upper surface of the support ring 1 has several slots for inserting rods with warning signs to serve as warnings.

[0038] Among them, the two sets of mounting blocks 5 are symmetrically distributed in a cross shape, and the distribution orientation of the mounting blocks 5 is adapted to the distribution orientation of the support blocks 43 on the support frame 2, so that the limiting rods 44 on the mounting blocks 5 can extend and retract to the corresponding support rods 6 during the sliding process.

[0039] In addition, the support rod 6 has several equally spaced limiting grooves on the side facing the limiting rod 44, and the specifications of the limiting grooves are compatible with the specifications of the limiting rod 44. The supporting ring 1 is limited and supported by the limiting rod 44 extending into the limiting groove, while the limiting rod 44 extending into the limiting grooves in different directions can limit and support the supporting ring 1 after the lifting and adjusting.

[0040] In an optional embodiment, the support member 9 includes a crossbar 91 fixedly connected in the mounting groove 8, a sliding block 92 slidably connected to the crossbar 91, a support spring 93 fixedly connected between the sliding block 92 and the inner side of the mounting groove 8, and a stop plate 94 fixedly connected to the lower end of the sliding block 92.

[0041] In this embodiment, the abutment plate 94 located below the support frame 2 is elastically supported by the sliding block 92 and the support spring 93. Therefore, during the placement process, the abutment plate 94 can be squeezed into the wall of the steel casing or pile hole, providing stable support for the entire enclosure structure and improving the stability of the entire enclosure structure during placement.

[0042] It should be noted that the mounting groove 8 and the crossbar 91 are symmetrically distributed in a cross shape, just like the support frame 2. The lower end of the abutment plate 94 is inclined with a narrow bottom and a wide top, so that when the inclined part of the abutment plate 94 is squeezed, it can slide towards the center of the support ring 1 through the sliding block 92 to meet the support of steel casings or pile holes of different specifications. In addition, the side of the abutment plate 94 near the mounting block 5 is serrated, so that the serrated side of the abutment plate 94 increases the friction after contact when it comes into contact with the inner wall of the steel casing or pile hole.

[0043] The working principle in the above embodiments is as follows:

[0044] When the entire retaining structure is placed above the steel casing or the pile hole without a steel casing, the lower end of the abutment plate 94 is inclined. Therefore, during the placement process, the inclined part of the abutment plate 94 can be squeezed and elastically slide towards the center of the support ring 1 through the support spring 93 and the sliding block 92. After the serrated side of the abutment plate 94 extends into the steel casing or the pile hole, the reset support spring 93 can pull the sliding block 92 to drive the abutment plate 94 to fit tightly against the inner wall of the steel casing or the pile hole, providing stable support for the support ring 1.

[0045] When protecting a pile hole with a steel casing, by rotating the rotating rod 41, the limiting rod 44 is pulled apart from the support rod 6 by the pull rod 47, and the support limiting of the support ring 1 can be released, so that the support ring 1 can be raised and lowered on the support rod 6 by the mounting block 5. After the support ring 1, support frame 2 and wire mesh 3 are lowered to fit with the opening of the steel casing, the opening of the steel casing can be covered. In addition, the telescopic rod 7 under the support ring 1 works with the steel casing to provide double-layer protection for the opening of the pile hole.

[0046] When protecting pile holes without steel casings, the support ring 1 can still be lowered in the above manner. The lowered support ring 1 can drive the telescopic rod 7, which surrounds the pile hole, to extend and retract against the surface of the pile hole opening, forming a protective measure around the pile hole surface to prevent debris from falling into the pile hole and improve the protective effect.

[0047] The entire retaining structure can be used not only for the protection of pile holes after construction, but also for the protection of pile holes during construction, thereby improving the adaptability of the entire retaining structure.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
