Description

Technical Field

[0001] The utility model relates to the technical field of engineering instruments, in particular to a polymer I-shaped pile sinking auxiliary device. Background Art

[0002] Steel sheet piles are widely used in engineering fields such as bank slope support and foundation pit support. Generally, high-frequency vibration hammers are used to sink steel sheet piles into the soil one by one to play a supporting and anti-seepage role. Adjacent steel sheet piles are connected and fixed with a locking structure. In recent years, with the rapid development of science and technology and the continuous improvement of environmental protection requirements, "plastics instead of steel" and "plastics instead of wood" have become international trends. Polymer piles, which are made of polymer reinforced composite materials mixed with a variety of additives and extruded in one time, have emerged and been widely used.

[0003] Polymer piles are generally divided into polymer U-shaped piles, polymer square piles, polymer porous piles, polymer I-shaped piles, etc. according to their cross-sectional forms. Various pile types can be connected through a unified lock to form a polymer retaining wall. Among them, polymer I-shaped piles are mainly used to improve the bending resistance of polymer retaining walls due to their special structural form. By using them in combination with other polymer pile types, the bending resistance of the overall retaining wall is greatly improved, further expanding the application scope of polymer retaining walls.

[0004] For example, the Chinese patent announcement number: CN215759009U is an auxiliary device for hammering polymer square piles for slope support, which is applied to a square pile. When the utility model is operated, the square pile is first sleeved outside the support tube from below, and the top of the square pile is clamped in the gap between the outer sleeve and the support tube. The connecting joints on both sides of the square pile slide along the notch on the outer sleeve, and then the outer sleeve and the support tube are hammered, which effectively avoids the problems of square pile fragmentation and breakage, and improves the construction efficiency. After the square pile is hammered in place, the outer sleeve and the support tube can be lifted up;

[0005] And, Chinese Patent Publication No.: CN214993822U An auxiliary device for hammering polymer sheet piles in river channels. During construction, the utility model first installs the sheet pile on the backing plate, then inserts the sheet pile and the backing plate into the soil together, and pulls out the backing plate after the insertion is in place. The operation is quick and convenient; because the length of the backing plate is greater than the length of the sheet pile, the bottom of the backing plate directly acts on the soil, effectively protecting the sheet pile, and preventing the sheet pile made of polymer material from being affected by gravel and masonry in the soil layer during construction, resulting in difficulty in insertion and breaking; the width of the backing plate is less than the width of the sheet pile, effectively preventing the backing plate from affecting the normal connection of the connecting joints on both sides of the sheet pile;

[0006] However, in current engineering practice, polymer I-piles are difficult to construct because of their large width of web and wing plates when they are sunk into miscellaneous fill layers or other hard soil layers containing debris such as gravel and bricks. They are prone to web or wing plate fragmentation and cracking, which seriously affects their engineering performance and construction efficiency.

[0007] Therefore, it is necessary to develop a polymer I-pile sinking aid. Utility Model Content

In addition, the length of the pile sinking assistant is greater than the length of the I-beam pile, which can effectively protect the bottom end of the I-beam pile from being damaged by hard objects.
