Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pile foundation engineering of all kinds of building structure systems, and particularly relates to an ecological arched sheet pile. BACKGROUND

[0002] Large underground buildings, slopes, tunnels, port wharf walls and river revetments, etc. require temporary or permanent enclosure of their own or the surrounding buildings during construction. Currently, most of the revetment walls commonly used are formed by inserting multiple reinforced concrete round piles combined with cement mixing piles into the soil, or multiple T-shaped piles or U-shaped sheet piles or cement mixing piles made by the SMW method are inserted into the soil to form the enclosure wall. Taking the U-shaped sheet pile as an example, it includes a pile body composed of a top, two waist portions on the left and right sides of the top and extending downward, and a lower flange at the bottom of the two waist portions and extending horizontally outward. The cross section of the pile body is in the shape of a U with a top, two waist portions and two lower flanges. Multiple ecological holes for water exchange are formed in the two waist portions near the pile head of the U-shaped sheet pile. However, the ecological holes only have water exchange and provide habitat for fish and shrimp.

[0003] Therefore, the applicant has applied for a Chinese utility model patent with the patent number CN202220015630.6 (authorized publication number CN216839382U) for a U-shaped ecological sheet pile and a protective wall using the same. The base plate and the two waist portions of the U-shaped ecological sheet pile form a U-shaped groove together. Multiple ecological holes for plant growth are formed in the base plate along its length direction and through its wall thickness. The ecological holes are formed in the base plate of the sheet pile, so the space of the ecological holes is larger, i.e. the space for plant growth is larger, which is beneficial to the growth of plants.

[0004] However, the ecological holes and the ecological sheet pile are integrally formed, which requires complex core-pulling design for the manufacture of the ecological sheet pile with ecological holes, resulting in manufacturing difficulties and high manufacturing costs. Moreover, the ecological holes cannot hold soil or water, cannot cultivate plants like a pot, and cannot provide habitat for fish and shrimp like a fish tank. UTILITY MODEL CONTENTS

The ecological cavity 3 can hold sand, provide habitat for fish and shrimp, and provide space for plant growth. The concave arc-shaped portion 21 can provide more space for fish and shrimp to inhabit and plants to grow. The partition member 2 is designed to be detachable. During manufacturing, the partition member 2 and the pile body 1 can be manufactured independently, that is, the mold for the pile body 1 and the partition member 2 can be opened separately, avoiding the complex core-pulling design required for mold manufacturing, reducing the difficulty of mold manufacturing, and reducing the manufacturing cost. At the same time, the number of partition members 2 and the installation position on the pile body 1 can be adjusted according to actual needs to adapt to different water depths and soil environments.

[0027] In order to facilitate the installation of the partition member 2, as shown in the figure. Figures 4-6As shown, the partition member 2 of the embodiment further comprises a first fitting part 22 extending outwardly at the top of the arc-shaped part 21, and a second fitting part 23 extending outwardly at the bottom of the arc-shaped part 21, the U-shaped slot 13 is provided with a first insertion slot 14 matched with the first fitting part 22, and a second insertion slot 15 matched with the second fitting part 23, during installation, the first fitting part 22 is aligned with the first insertion slot 14, the second fitting part 23 is aligned with the second insertion slot 15, and the partition member 2 is fitted on the pile body 1 by force, so that the installation of the partition member 2 is completed, and the installation is simple and fast.
