Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an inflatable pile hole protector. Background Technology

[0002] With the centralization of cities and the concentration of population in urban areas, demolition and renovation projects in city centers often choose static pressure piles. This is a pile driving process in which the pile driving mechanism of a static pressure pile driver uses the pile driver's own weight and the counterweight on the frame to provide reaction force to press precast piles into the soil. However, after static pressure pile construction, many circular holes are left on the ground before the concrete is poured. The depth of the precast piles ranges from several meters to more than ten meters. Opening the holes not only poses a great safety risk, but also affects the construction quality if soil falls in.

[0003] The existing precast pile openings are usually protected by setting up warning tapes, but this protection is easily damaged and only serves as a warning without any actual protective function. In addition, there is also the practice of directly covering the opening with steel mesh, steel plates or formwork, but the above coverings are easy to shift and not secure, posing a great safety hazard. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an inflatable pile hole protector that seals the pile hole, avoiding the safety risks associated with open pile holes and the problem of soil falling in and affecting construction quality.

[0005] To achieve the above objectives, the present invention provides an inflatable pile hole protector, comprising:

[0006] An airbag is used to abut against the inner wall of the precast pile hole. The top of the airbag is open and threadedly connected to an inflatable check valve for connecting to an air pump. A first rain cover is installed between the inflatable check valve and the airbag. The side of the first rain cover opposite to the inflatable check valve is connected to the top of the precast pile along the height direction. The airbag is provided with a warning mechanism, which includes a pressure gauge fixedly installed on the top of the airbag and an alarm bell connected to the pressure gauge signal.

[0007] Preferably, the shape of the airbag matches the shape of the inner wall of the precast pile.

[0008] Preferably, the top of the airbag and the top of the first rain cover are respectively provided with a first hole, and a pin for fixing the airbag and the first rain cover to be fixedly connected with the limiting ring is inserted in the first hole.

[0009] Preferably, a second hole is provided on one side of the first hole on the first rain cover, and a carrying handle is inserted and fixedly connected in the second hole.

[0010] Preferably, a plurality of retractable compression cylinders are uniformly installed in the airbag along the circumferential direction, and a compression spring is fixedly installed in each of the plurality of compression cylinders along the radial direction of the airbag.

[0011] Preferably, the warning mechanism further includes a night vision light mounted on top of the airbag and located on one side of the barometer.

[0012] Preferably, a second rain cover is installed on the top of the airbag, and a foldable rain cover is fixedly connected to the outer side of the second rain cover along the circumferential direction. The second rain cover and the rain cover are located on the top of the barometer, the alarm bell and the night vision light.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects:

[0014] 1) It achieves the sealing of the precast pile hole opening and can sound an alarm when the internal air pressure is insufficient, so that the staff can deal with it in time.

[0015] 2) The rain cover can protect the pressure gauge, alarm bell, night vision light and inflation check valve from water and dust.

[0016] 3) The installation of night market lights can provide illumination at night and prevent workers and concrete mixer trucks from accidentally hitting the top of the precast piles during nighttime construction. Attached Figure Description

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Please see Figures 1 to 7 As shown, the present invention provides an inflatable pile hole protector, including an airbag 1 for abutting against the inner wall of the precast pile hole. The top of the airbag 1 is open and threadedly connected to an inflatable check valve 2 for connecting to an air pump. The shape of the airbag 1 matches the shape of the inner wall of the precast pile. In this embodiment, it is cylindrical. The cylindrical airbag 1 has a rough surface and a certain thickness, which can withstand the compression of fine particles on the inner surface of the precast pile. The airbag 1 is connected to the air pump through the inflatable check valve 2. After the airbag 1 is inflated, it abuts against the inner wall of the precast pile hole and is not easily dislodged by friction.

[0031] Furthermore, a first rain cover 3 is installed on the top of the airbag 1 between the inflatable check valve 2 and the airbag 1. The first shaft and the side of the 3 opposite to the inflatable check valve 2 are connected to the top of the precast pile along the height direction. Preferably, the top of the airbag 1 and the top of the first rain cover 3 are respectively provided with a first hole 5. A pin 6 is inserted into the first hole 5 to fix the airbag and the first rain cover 3 in conjunction with the limiting ring 7. The limiting ring 7 can lock the pin 6 so that it will not slip out of the first hole 5.

[0032] Furthermore, a second hole 10 is provided on one side of the first hole 5 on the first rain cover 3. A handle 11 is inserted into and fixedly connected to the second hole 10. The handle 11 makes it easy to lift the entire device by hand.

[0033] Please see Figures 5 to 9 As shown, multiple retractable compression cylinders 8 are evenly installed inside the airbag 1 along the circumferential direction, and compression springs 9 are fixedly installed inside the multiple compression cylinders 8 along the radial direction of the airbag 1.

[0034] Furthermore, the airbag 1 is also equipped with a warning mechanism 4. The warning mechanism 4 includes a pressure gauge fixedly installed on the top of the airbag 1 and an alarm bell connected to the pressure gauge signal. The warning mechanism 4 also includes a night vision light installed on the top of the airbag 1 and located next to the pressure gauge. In this embodiment, a pressure sensor is installed on the pressure gauge, and the pressure sensor is electrically connected to the alarm bell. The pressure gauge can display the real-time pressure value. When the air pressure inside the cylindrical airbag drops to a certain level, causing a decrease in friction and preventing proper sealing, the pressure sensor transmits an electrical signal to the alarm bell, which then sounds. The purpose of setting up the night vision light is to provide illumination to prevent workers and concrete mixer trucks from accidentally hitting the top of the precast pile during nighttime construction.

[0035] Furthermore, a second rain cover 12 is installed on the top of the airbag 1. A foldable rain cover 13 is fixedly connected to the outer side of the second rain cover 12 along the circumferential direction. The second rain cover 12 and the rain cover 13 cover the top of the pressure gauge, alarm bell and night light. In this embodiment, the second rain cover 12 is transparent, so the value of the pressure gauge can be seen through it, and the light tube of the night vision light can also be seen through it. At the same time, the second rain cover 12 blocks the pressure gauge, alarm bell, night vision light and inflation check valve from water and dust.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
