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 a louver type ecological pile. BACKGROUND

[0002] Large underground buildings, slopes, tunnels, port wharf walls and river revetments, etc. require temporary or permanent protection of the foundation of the building itself or surrounding buildings during construction. The commonly used revetment walls are mostly formed by inserting multiple reinforced concrete round piles combined with cement mixing piles into the soil to form a protection wall, or by inserting multiple T-shaped piles or U-shaped sheet piles into the soil to form a protection wall. Taking the U-shaped sheet pile as an example, it includes a pile body composed of a top portion, two waist portions located on the left and right sides of the top portion and extending downward and outward, and two lower flanges located 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, which is composed of the top portion, the two waist portions and the two lower flanges. Because the piles are closely connected, water cannot penetrate through this type of protection wall structure, completely blocking the river from the embankment, and disrupting the ecological balance of the river embankment.

[0003] Therefore, the applicant has applied for a Chinese utility model patent with the patent number CN202022858333.1 (publication number CN215593863U) entitled "Ecological Revetment Based on U-shaped Sheet Pile", which discloses an ecological pile including a pile body composed of a top portion, two waist portions located on the left and right sides of the top portion and extending outward, and two lower flanges located at the bottom of the two waist portions and extending horizontally outward. The pile body is composed of the top portion, the two waist portions and the two lower flanges, and the U-shaped groove formed by the top portion and the two waist portions has multiple ecological holes on the two waist portions near the pile head for water exchange. The U-shaped groove also has multiple back rib portions arranged along the length direction. The height of the back rib portions is less than the depth of the U-shaped groove, and the U-shaped groove between the uppermost back rib portion and the thickened portion forms a water exchange transition chamber. The ecological holes are connected to the outside world, and the mouth end of the water exchange transition chamber is covered with a cover plate having multiple water permeable holes.

[0004] However, the aforementioned water permeable channels or ecological holes have very limited space for plant growth, and only have the functions of water exchange and providing habitats for fish and shrimp. UTILITY MODEL CONTENTS

[0005] The first technical problem to be solved by the utility model is to provide a louver type ecological pile with multiple layers of ecological cavities arranged vertically.

[0006] The utility model discloses a louver type ecological pile which solves the first technical problem, comprising a pile body, the pile body has a top, a waist part extending downward and outward on both sides of the top, and the top and the waist part jointly form a forward recess part arranged along the length direction; characterized in that: a plurality of partition parts are formed in the forward recess part and arranged along the length direction of the forward recess part, each partition part is arranged downward and inwardly inclined, to form an ecological cavity in the forward recess part above each partition part, and a communication hole is formed in the waist part to communicate the ecological cavity with the outside.

[0007] As an improvement, the top part in the forward recess part is provided with a thickened part, the top surface of the thickened part is flush with the upper end surface of the pile body, and the lower bottom surface of the thickened part is a slope gradually inclined upward from inside to outside. The setting of the thickened part increases the cross-sectional area at the pile head position and increases the strength of the pile head, so that the impact force of the pile hammer can be dispersed in the piling process due to the increased contact area of the pile hammer and the pile head, and the strength of the pile head is also increased, and under the combined action of the two, the pile head is effectively prevented from being cracked or damaged in the piling process, the appearance of the enclosure and the structural performance of the concrete pile are ensured, compared with the increase of the metal end plate, the cost of the thickened area is lower, and no additional fixing steps are required, only adaptive adjustment of the sheet pile mold is required, and the process is simple.

[0008] Further improvement, the waist part is also provided with an ecological hole penetrating the outer end surface of the thickened part. The setting of the ecological hole can plant plants at the pile head position, and also plays a role in decorating the sheet pile, so that the sheet pile has aesthetic appearance.

[0009] As an improvement, the cross section of the forward recess part is semicircular or semi-elliptical. Compared with the traditional trapezoidal recess part, the entire recess part is arc-shaped transition, which can strengthen the overall strength of the sheet pile, especially solve the problem of stress concentration and cracking at the inner folding line position of the U-shaped sheet pile, expand the application range of small pile type, and provide the possibility for centrifugal production of piles.

[0010] As a specific pile type, the cross section of the forward recess part is trapezoidal. The forward recess part is the same as the existing U-shaped sheet pile.

[0011] As an improvement, a back rib is also formed within the aforementioned positive groove. The height of the back rib is less than the depth of the positive groove. The back rib has an outer end face, an upper end face, and a lower end face. The outer end face of the back rib is flat, the upper end face is a slope or arc surface that gradually slopes downwards from the inside to the outside, and the lower end face is a slope or arc surface that gradually slopes upwards from the inside to the outside. The aforementioned back rib effectively strengthens the original weak points of the pile body, plays a crucial role in enhancing the structural performance and stability of the concrete pile, and reduces vertical cracks caused by the concrete pile during construction. The spaced back ribs, after pile driving, can increase the vertical friction of the pile in the soil, even in soft soil or silt layers, reducing the pile length and saving resources. In addition, the sloped upper and lower end faces of the back rib also facilitate demolding.

[0012] Further improvements include a wedge-shaped surface on one of the two sides of the pile tail, which gradually slopes inward and extends to the pile tail end face. This wedge-shaped angle on one side of the pile tail creates a soil-squeezing effect during driving, pushing the sheet pile closer to the side of the adjacent preceding sheet section. This ensures a tighter bond between the two adjacent sheet sections, resulting in higher retaining strength from the sheet pile assembly.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: Multiple partitions are formed near the pile head within the forward groove, spaced apart along the length of the forward groove. Each partition is inclined downwards from the outside in. An ecological cavity is formed above each partition within the forward groove. Therefore, the pile body forms multiple ecological cavities spaced vertically, providing more habitats for fish, shrimp, and other animals. Each habitat is independent, and a connecting hole at the waist facilitates soil and water exchange on the bank. Plants can also grow in the ecological cavities, creating a more layered effect. Banks constructed using this ecological pile are aesthetically pleasing and practical. Attached Figure Description
