Description

Technical Field

[0001] The utility model belongs to the technical field of pile cores and pile holes, and in particular relates to an external protective mechanism for a pile core and pile hole. Background Art

[0002] The pile core refers to the average diameter of the pile. In bored piles, it represents the average inner diameter of the retaining wall. For bored piles, the concept of pile core does not apply, as bored piles lack a core. Instead, the diameter is used to calculate the project volume. The pile hole refers to the hole drilled for driving steel pipe and concrete pipe piles. This type of hole is similar to the foundation pile hole, but is used to drive prefabricated pipe columns. Concrete pipe is often used in foundation construction for bridge piers, chimneys, tower structures, and other structures.

[0003] The pile core and pile hole protection currently on the market has the following problems:

[0004] 1. After the traditional pile core and pile hole are constructed, the pile hole is exposed in the soil layer. Soil and rocks above may fall into the pile hole and block the pile core. After the excavation is completed, the blocked pile core needs to be manually cleaned. The traditional protective structure needs to be spot welded, which is complicated to disassemble and greatly increases the construction difficulty.

[0005] 2. When the traditional pile core and pile hole protection device encounters rain and other weather conditions, rainwater may enter the pile hole, causing water accumulation inside the pile hole. The accumulated water inside needs to be cleaned before construction, which greatly increases the difficulty of cleaning. Utility Model Content

[0006] The purpose of the utility model is to provide an external protection mechanism for a pile core and a pile hole, so as to solve the technical problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the specific technical solution of the present invention is as follows: an external protective mechanism for a pile core and pile hole, comprising a ground, a pile hole and a trapezoidal cover. Preferably, a pile hole is opened on the ground surface, a column shell is inserted into the inner side of the pile hole, a first through-hole is opened on the surface of the column shell, a movable rod is inserted into the inner side of the first through-hole, one end of the movable rod is fixedly connected to a push plate, the other end of the movable rod is fixedly connected to a grip plate, the grip plate surface is fixedly connected to a spring, and the other end of the spring is fixedly connected to a retaining ring.

[0008] Preferably, a water tank is provided on the top of the trapezoidal cover, a water channel is provided on the surface of the water tank, a slot is provided on the bottom of the trapezoidal cover, and a baffle is inserted into the inner side of the slot.

[0009] Preferably, a baffle is fixedly connected to the top of the plug column housing, a second through-hole is provided on the surface of the grip plate, and a connecting rod is inserted into the inner side of the second through-hole.

[0029] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the external protection mechanism for pile core and pile hole of the present invention in conjunction with the accompanying drawings.

[0030] like Figure 1-6 When the pile is in the hole, the push plate 5 is fixed to the bottom of the pile hole 2, and the baffle 4 is provided on the top of the pile hole 2 to prevent soil from entering. When the protective structure needs to be removed, it is only necessary to hold the gripping plate 6 and move it toward the center to make the push plate 5 fit the column housing 3. In this way, the protective structure can be removed more easily, which greatly reduces the construction difficulty.

[0031] A water trough 14 is provided on the top of the trapezoidal cover 17, and a water channel 16 is provided on the surface of the water trough 14. A slot 19 is provided at the bottom of the trapezoidal cover 17, and the baffle 4 is inserted into the inner side of the slot 19. In this way, through the trapezoidal cover 17 structure provided on the top of the pile hole 2, when encountering rainy weather, the water trough 14 provided on the surface of the trapezoidal cover 17 will largely prevent rainwater from directly contacting the baffle 4, and then discharge the rainwater from the water channel 16 provided on the surface of the water trough 14, thereby preventing the occurrence of water accumulation in the pile hole 2 to a large extent and greatly reducing the difficulty of cleaning.

[0032] The baffle 4 is fixedly connected to the top of the column housing 3, and a second through hole 11 is opened on the surface of the grip plate 6. The connecting rod 9 is inserted into the inside of the second through hole 11. In this way, the grip plate 6 is connected through the connecting rod 9 through the second through hole 11 opened on the surface of the grip plate 6, so that the grip plate 6 will not shake, thereby greatly improving the stability of the device.

[0033] A third through-hole 12 is provided on the surface of the grip plate 6, and the top of the trapezoidal cover 17 is fixedly connected to the handle 15. Professionally, through the third through-hole 12 provided on the surface of the grip plate 6, when the protective structure needs to be taken out, the third through-hole 12 provides a force point, making it easier to take out the column housing 3, thereby greatly improving the practicality of the device.

[0034] A sealing groove 18 is provided on the surface of the ground 1, and a sealing ring 20 is inserted into the inner side of the sealing groove 18. The top of the sealing ring 20 is fixedly connected to the baffle 4. In this way, the sealing ring 20 provided at the bottom of the baffle 4 can prevent rainwater from seeping into the pile hole 2 through the gap to a large extent, thereby greatly improving the sealing performance of the device.

[0035] The surface of the retaining ring 10 is fixedly connected to the fixed tube 13, the surface of the fixed tube 13 is fixedly connected to the column housing 3, and the movable rod 8 is inserted into the inner side of the fixed tube 13. In this way, by providing the fixed tube 13 structure, the movable rod 8 is prevented from shaking during movement to a great extent, thereby greatly improving the stability of the device.

[0036] The working principle of the external protection mechanism for the pile core and pile hole is as follows: the pile hole 2 is temporarily blocked before the pile foundation is constructed, and the column shell 3 is inserted into the pile hole 2. The push plate 5 provided on the surface of the column shell 3 will be more stably attached to the inside of the pile hole 2 under the action of the spring 21. The baffle 4 provided on the top will prevent mud from entering, which greatly saves the processing time of the pile hole 2 and shortens the construction period. The sealing ring 20 provided at the bottom of the baffle 4 can prevent rainwater from seeping into the pile hole 2 from the gap to a large extent, thereby greatly improving the sealing performance of the device. A trapezoidal cover 17 structure is provided on the top of the pile hole 2. In case of rain, When the weather is bad, the water trough 14 provided on the surface of the trapezoidal cover 17 will largely prevent rainwater from directly contacting the baffle 4, and then drain the rainwater from the water channel 16 opened on the surface of the water trough 14, thereby largely preventing the occurrence of water accumulation in the pile hole 2 and greatly reducing the difficulty of cleaning. During the construction stage, when it is necessary to remove the protective structure, first pull the handle 15 to take out the trapezoidal cover 17, and then just insert your hand into the third through-hole 12 on the inner side of the grip plate 6 and grip it tightly, so that it moves toward the center, and the push plate 5 can be moved away from the inner side of the pile hole 2, so that the protective structure can be removed more easily, which greatly reduces the difficulty of construction.

[0037] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
