A kind of pile pole used for hydrological observation station on coastal tidal flats

Abstract

The invention relates to a high-construction-efficiency pile for an offshore tidal-flat hydrometric station. The high-construction-efficiency pile comprises a long pipe and is characterized in that several arc plates are hinged to the lower end of the long pipe, every two adjacent arc plates are in contact fit with each other, the arc plates form a cone structure, several barbs are fixedly mountedon the periphery of each arc plate, the inner wall of each arc plate is hinged to the lower end of a barrel, a stud is mounted in each barrel in a threaded manner, the upper end of each stud extendsout of the corresponding barrel , the upper end of each stud is fixedly connected to the lower end of a vertical rod, the upper end of each vertical rod is slightly lower than the top surface of the long pipe, the top of the outer periphery of each vertical rod is provided with several parallel inverted-J-shaped grooves, a movable sleeve sleeves each vertical rod, and a guide device based on the movable sleeves is detachably mounted at the upper end inside the long pipe. The high-construction-efficiency pile has the advantages that the long pipe is 3-3.5M in length, steel materials can be saved, raw material cost can be saved favorably, pipe lowering can be completed fast due to the fact that the pipe is short, and pile sinking efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of hydrological observation, and in particular relates to a pile pole used for an offshore tidal flat hydrological observation station. Background technique [0002] The tidal flat refers to the tidal flooding zone between the high tide level and the low tide level of the coastal spring tide. Due to the effect of the tide, the tidal flat is sometimes submerged in water and sometimes exposed to the water surface. Hydrological observation stations are often built in tidal flat areas. In order to prevent hydrological observation stations from shifting under the action of wind and tide, construction workers fix the hydrological observation stations by sinking piles. Publication No. CN107460870A discloses a pile rod for hydrological observation stations near tidal flats , but it is easy to cause the expansion section to expand during pile sinking, and the elastic force of the binding rib is small and it is easy t...

Hydrological observation stations are often built in tidal flat areas. In order to prevent hydrological observation stations from shifting under the action of wind and tide, construction workers fix the hydrological observation stations by sinking piles. Publication No. CN107460870A discloses a pile rod for hydrological observation stations near tidal flats , but it is easy to cause the expansion section to expand during pile sinking, and the elastic force of the binding rib is small and it is easy to fail to play a role. The elastic force of the binding rib is large and will produce greater resistance to the expansion of the expansion section, which will cause additional labor burdens on the workers.
