Embodiment 1

[0033] The punching device applicable to silty soil and silty soil of the present invention includes a standpipe, a cross knife, and a circular knife.

[0034] see now figure 1 , figure 1 It is a schematic structural diagram of a punching device according to an embodiment of the present invention. As shown in the figure, the vertical pipe is a steel pipe with a diameter of 32mm, the length of the steel pipe is 900mm, the bottom end of the vertical pipe is set as the punching head 1, the top of the punching head is provided with a steel pipe conical cover, and the side wall of the punching head is provided with an orifice The top of the vertical pipe is set as a steel pipe joint 5, and the steel pipe joint can be connected with a water pipe (not shown in the figure) to connect the water through the iron wire binding, and the water pipe is connected to the submersible pump, and the top of the vertical pipe can also be connected with a wooden pole of a certain length. (not show...

Embodiment 2

[0038] figure 2 It is another exploded schematic diagram of the structure of the punching device according to the embodiment of the present invention, illustrating that the steel pipe joint 5 becomes a steel pipe joint through the first screw connection unit 6; the punching head 1 becomes a replaceable punch through the second screw connection unit 7. hole head. In this embodiment, except that the diameter of the standpipe is a steel pipe of 50 mm, the cross knife is a steel plate with a width of 100 mm, the ring knife is a steel ring with a thickness of 6 mm, and the punching head is a detachable movable joint, which is convenient for replacement according to different soil layers and different apertures. Punching head, the punching head is a long tapered head with an aperture, the length of the tapered head is 150mm, except that the length of the threaded part is 50mm, all the other are the same as in embodiment 1.

Embodiment 3

[0040] The method for using the punching device applicable to silt and silt soil of the present invention comprises the following steps:

[0041] a. Connect the end of the steel pipe joint to the water pipe with iron wire, connect the end of the water pipe to the submersible pump, and place the submersible pump in the nearby reservoir;

[0042] b. Bind the steel pipe joint end firmly with the wooden pole with iron wire, and the length of the wooden pole is determined according to the punching depth;

[0043] c. Stand the vertical pipe upright, the punching head is perpendicular to the surface layer, turn on the submersible pump, and the water will flow through the outlet at the front end of the punching head to impact the soil layer;

[0044] d. The operator holds the wooden pole and slightly impacts the soil layer up and down. The circular knife cuts the soil layer and protects the surrounding soil layer to avoid excessive punching of the soil layer and other shapes of the so...

Abstract

The invention provides a punching device suitable for floury soil and silt soil. The punching device comprises a vertical pipe, cross blades and a ring tool, and is characterized in that the verticalpipe is a steel pipe with diameter of 32 mm or 50 mm, length of the steel pipe is larger than or equal to 900 mm, a punching head is arranged at the bottom end of the vertical pipe, the cross blades are four steel plates which are 150 mm long and 50-100 mm wide, the ring tool is a steel ring which is 4 mm or 6 mm thick and 250 mm high, the diameter of the steel ring is 350 mm, a cutting edge is arranged at the bottom of the steel ring to facilitate soil cutting, and the circumference of the top of the steel ring is equally divided and fixedly welded with one ends of six supporting rods. The punching device suitable for floury soil and silt soil and a using method have the advantages as follows: the punching device is simple in structure, convenient to manufacture and high in use efficiency, holes formed in a soil layer are neat, the problem about hole forming in an alluvial soil layer is solved very well, furthermore, construction efficiency is improved, operation is convenient and simple, project progress is accelerated, and project cost is reduced.

Description

technical field [0001] The invention relates to a foundation punching device, in particular to a punching device suitable for silt and silt soil. Background technique [0002] For the soil layers at the estuaries of Hangzhou Bay, Liao River Estuary Delta, Yangtze River Estuary, Yellow River Estuary, etc., due to the special alluvial characteristics of the soil layer and geological origin, the soil layers in this area are flush fill soil, silty clay, sand Silty soil, muddy silty clay, and the soil has a high moisture content and a high groundwater table. Building construction, municipal road construction, and precipitation engineering in this area are the key. Tube well dewatering is a major form of dewatering engineering. The traditional tube well dewatering construction equipment has many, heavy equipment, complicated operation, difficult transportation, low work efficiency and low safety. Traditional precipitation equipment is unfavorable for alluvial formation construct...
