Description

Technical Field

[0001] This utility model relates to the field of pipe pile technology, and in particular to a pipe pile body reinforcement device. Background Technology

[0002] In the field of construction engineering, precast piles are what we know as reinforced concrete piles, steel piles, and wooden piles, etc. Generally speaking, in the field of pile foundation, most construction projects prioritize the use of reinforced concrete piles. Precast piles are usually prefabricated in factories or on construction sites and then transported to the location of the pile. With the application of hammering, static pressure and other processes, the piles are driven into the predetermined position. Compared with other piles, reinforced concrete precast piles have the advantages of stronger load-bearing capacity, smaller settlement deformation and higher efficiency in actual application.

[0003] Concrete pipe piles are widely used in civil engineering projects on soft soil foundations. However, during the pile driving process, the pile head is continuously hammered by a heavy hammer, and the pile body will gradually penetrate into the soil layer. During this process, the pile body is prone to slight displacement, which makes it impossible to maintain coaxial pressure when the heavy hammer hammers it. The edge of the pile head is easily hammered and damaged, and a certain shear stress will be generated in the transverse direction of the pile body, which can easily cause transverse cracks in the pile body. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe pile body reinforcement device that can vertically fit and slide the precast pipe pile body to limit its movement, thereby preventing the precast pipe pile from being damaged due to uneven stress caused by slight displacement, and ensuring efficient and stable pile driving.

[0005] To achieve the above objectives, a pipe pile reinforcement device is provided, comprising: a precast pipe pile, wherein a limiting sleeve is slidably fitted vertically on the outer side of the precast pipe pile body, and symmetrically fixed plates are fixed on the outer side of the limiting sleeve; counterweight seats are symmetrically fixed on the left and right sides of the insert plates; side frames are fixedly connected to the opposite top sides of the counterweight seats; top seats are fitted and fixedly fitted on the top of the opposite sides of the side frames; limiting slide plates are fitted on the opposite bottom sides of the top seats; the bottom of the limiting slide plates is fitted and fixedly fitted with the counterweight seats; and a pad is slidably fitted vertically on the opposite side of the limiting slide plates. A hammer pressing platform is fixedly connected to the top center of the pad, and an annular groove is opened at the bottom center of the pad, which slides and fits into the pile head of the precast pipe pile. By setting a limiting sliding sleeve, the pile body of the precast pipe pile is first fitted and slidably limited in the vertical direction. Then, the pad and hammer pressing platform are nested in the pile head of the precast pipe pile to withstand the hammering. The limiting sliding plate is used to limit and correct the force output direction of the hammer pressing platform and the pad, so that it is coaxially pressed with the pile head along the limiting sliding plate. This prevents the precast pipe pile from being damaged due to uneven force caused by slight displacement, and ensures that the pile driving is efficient and stable.

[0006] According to the aforementioned pipe pile reinforcement device, a steel pipe is wrapped around the outer side of the precast pipe pile, and the steel pipe is horizontally aligned with the upper and lower sides of the precast pipe pile. This increases the bearing area of ​​the pipe pile and improves its overall bearing capacity.

[0007] According to the aforementioned pipe pile reinforcement device, a non-slip pad is fixedly attached to the bottom of each counterweight base, and the bottom of each non-slip pad is in contact with the ground. This ensures the stability of the overall equipment's installation position.

[0008] According to the aforementioned pipe pile reinforcement device, a rubber pad ring is fixedly attached to the top inner side of the annular groove, and the bottom of the rubber pad ring is pressed and attached to the pile head of the precast pipe pile. This provides a relatively gentle transmission of hammer pressure.

[0009] According to the aforementioned pipe pile reinforcement device, rubber washers are fixedly arranged around the inner and outer edges of the bottom of the annular groove, and adjacent rubber washers are pressed and fitted against the pile body of the precast pipe pile. This prevents the washers from rebounding and detaching after hammering.

[0010] According to the aforementioned pipe pile reinforcement device, a wear-resistant liner is provided on the top surface of the hammer pressing platform, and the wear-resistant liner is designed to withstand the continuous hammering of the pile driving hammer. This improves the wear resistance of the top surface of the hammer pressing platform.

[0011] According to the aforementioned pipe pile reinforcement device, limiting slide rods are vertically mounted on both the front and rear sides of the limiting slide plate. These limiting slide rods slide vertically through the pad and are correspondingly engaged and fixed with the top seat and counterweight seat. This helps to enhance the limiting and transmission stability of the pad under stress.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] In this invention, a limiting sliding sleeve is first used to vertically fit and slide the precast pipe pile body, and then a pad is nested in the pile head of the precast pipe pile in conjunction with a hammer pressure table to withstand the hammering. The limiting sliding plate is used to limit and correct the force output direction of the hammer pressure table and the pad, so that they are coaxially pressed along the limiting sliding plate and the pile head. This prevents the precast pipe pile from being damaged due to uneven force caused by slight displacement, thus ensuring efficient and stable pile driving.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
