Technical Field
The utility model belongs to instrument for the construction, concretely relates to be used for PHC tubular pile to dig instrument of fetching earth soon.
Background
With the development of reform and open and economic construction, pretensioned prestressed concrete pipe piles (PHC pipe piles for short) are beginning to be applied to railway systems in large quantities and are expanded to the fields of industrial and civil buildings, municipal works, metallurgy, ports, highways and the like. In Yangtze river delta and Zhujiang delta areas, the demand of the pipe pile is increased greatly due to the fact that geological conditions are suitable for the use characteristics of the pipe pile. The pretensioned prestressed concrete pipe pile is developed rapidly because of its advantages of strong load capacity, small settlement deformation and high efficiency.
The PHC tubular pile is a hollow cylindrical body elongated concrete prefabricated component manufactured by adopting a pretensioning method prestress process and a centrifugal forming method, and mainly comprises a cylindrical pile body, an end plate, a steel ferrule and the like. During construction, two pile sinking modes, namely a hammering method and a static pressure method, are mainly adopted, more open pile tips (shoes) are adopted in an offshore area, a soil squeezing effect is generated during pile sinking, and the inner cavity of a pile body is plugged by a soil body after the open pile tips (shoes) sink into a soil layer.
In order to effectively prevent the foundation from floating upwards and ensure the integral cooperative work of the foundation and a pile foundation, before the reinforcement of a raft foundation is bound, a supporting plate is arranged in the pile top and a reinforcement cage is placed in the pile top, and then micro-expansion concrete core filling pouring is adopted, so that the connection of a pipe pile and the foundation is ensured. Therefore, after the earth is excavated to the designed elevation and the pipe pile is exposed, the core filling soil in the pipe pile hole needs to be cleaned, the mechanical soil excavation is limited by the inner diameter of the pile core and the soil excavation depth, and the soil cleaning is carried out by machines of different models.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims to provide a not enough to prior art, provide one kind and be used for PHC tubular pile to dig the instrument of fetching earth soon.
The technical scheme is as follows: the utility model relates to a be used for PHC tubular pile to dig the instrument of fetching earth soon, including fetching earth dish, a plurality of connecting rods, three sets of sleeves and a plurality of levers; the utility model discloses a soil sampling dish, including soil sampling dish connecting rod, soil sampling dish, connecting rod, cover wire, the cover wire is connected through the cover wire between soil sampling dish connecting rod and the connecting rod, the cover wire is connected between the connecting rod, the cover wire is connected to the top side of soil sampling dish connecting rod and connecting rod both ends end side respectively retreat 50mm department vertical fixation and have the sleeve pipe, the sleeve pipe is 60 each other, and the range of layering stack is arranged, the cover wire cup joints the lever in the sleeve pipe.
Preferably, the soil sampling disc connecting rod is a galvanized steel pipe with the outer diameter not less than 30mm and the length not less than 500mm, and the outer diameter of the right circular structure of the soil sampling disc is 5mm smaller than the inner diameter of the PHC tubular pile.
Preferably, the length of the filament head is 30 mm.
Preferably, the connecting rod is a galvanized steel pipe with the diameter not less than 30mm and the length is 1500 mm.
Preferably, the angle of inclination of the semicircular structure itself to the horizontal is 10 °.
Has the advantages that: (1) the utility model connects the connecting rod of the soil-taking disc with the connecting rod through the mantle fiber, inserts the lever into the mantle tube at the top end of the connecting rod to rotate the soil-taking disc clockwise, cuts the filled soil through the included angle of the disc, and promotes the soil-taking; when the length of a single connecting rod does not meet the rotary digging depth, a connecting rod is added through a mantle fiber until the soil taking depth is met, the utility model is suitable for hollow pipe piles with different soil taking depths, almost no transport tool or power supply is needed, and the hollow pipe pile is more convenient and energy-saving;
(2) the utility model has the advantages of simple structure, the instrument is light, the ann tears simple, low cost open to but recycle can improve the efficiency of fetching earth.
