Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pile foundation construction, especially to a novel pile core pollution prevention construction device. BACKGROUND

[0002] In pile foundation construction, prefabricated pipe piles are usually installed at construction positions, and the pile core is poured with concrete to improve the bearing capacity and stability of the pile foundation. Before pouring, the pile core needs to be plugged to prevent pollution.

[0003] Currently, the traditional way to prevent pile core pollution is to place a plugging material on the top of the pile core. However, displacement and damage may occur during construction, causing mud, garbage, and other materials to enter the pile core. The interior of the pile core needs to be cleaned, pumped, and other work, which seriously affects the pile core pouring construction quality and construction efficiency, and also causes material waste during excavation. SUMMARY

[0004] To improve the problems in the above background technology, the utility model provides a novel pile core pollution prevention construction device.

[0005] The utility model provides a novel pile core pollution prevention construction device adopts the following technical scheme:

[0006] A novel pile core pollution prevention construction device comprises a base, a vertical steel bar is connected to the center of the base, a fixing device is connected to the top end of the vertical steel bar, the base is fixed in the pile core through the fixing device, and the vertical steel bar is surrounded by an air bag and blocks the pile core through the air bag.

[0007] Preferably, the fixing device comprises a horizontal sleeve, two horizontal steel bars are sleeved on both sides of the sleeve, and the outer ends of the horizontal steel bars extend out of the sleeve.

[0008] Preferably, external threads are formed on the inner end surface of the horizontal steel bar and are threadedly connected with the sleeve, and a screw rod is screwed to the side surface of the sleeve and fastens the horizontal steel bar.

[0009] Preferably, the air bag is connected with a gas charging and discharging pipe, the gas charging and discharging pipe extends to the outside of the pile core, and a valve is installed at the end of the gas charging and discharging pipe.

[0010] Preferably, the base is cut into a circular shape from a 1.8mm-thick patterned steel plate.

[0011] Preferably, the air bag uses a ring structure, and the air bag is a rubber air bag.

[0012] In summary, the utility model has the following beneficial technical effects:

[0013] 1. This utility model has a simple structure and can be used to seal the pile core to prevent pile core contamination. The base is fixed inside the pile core by a fixing device, and an annular airbag is used to seal the pile core to prevent mud or garbage from falling into the pile core due to displacement or damage of the sealing material. This reduces the possibility of cleaning the pile core and pumping water, improves the construction efficiency and quality of pile core grouting, and reduces the loss rate during earthwork excavation, thus achieving the purpose of civilized construction, cost reduction and efficiency improvement.

[0014] 2. The annular airbag fills the gap between the outside of the vertical reinforcement and the inside of the pile core. It is supported and fixed by the base and the fixing device, which has a better sealing effect. The fixing device is located above the airbag, which makes it easy to put in and take out the device and adjust its position. When put in, the airbag is not inflated, which makes it easy to lower. After the airbag is put in, it is inflated to ensure the sealing effect. At the same time, the base and airbag can be removed when the pile core is poured, so that the base and airbag can be reused. Compared with the traditional sealing baffle, it can save a lot of materials. Attached Figure Description
