Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The tubular well pore-forming device is suitable for pore-forming of a well point downcast tubular well in the process of excavating a silty soil foundation pit, and the pore-forming depth is generally not more than 25 m.

As shown in fig. 1, the tube well hole forming device comprises a tube body 1, a cylinder 2 sleeved outside the tube body 1, and a tapered part 3 connected to the lower end of the tube body 1.

Body 1 in this embodiment adopts the steel pipe, during the use, body 1's upper end is as intaking the end, the lower extreme is as going out the water end, be connected with outside water source for convenience, be connected with the connecting pipe 6 that can buckle in body 1's upper end, so can be more convenient butt joint water pipe, during the use, be connected the water pipe between connecting pipe 6 and the water source, and the water source position that supplies water then sets up the water pump, in order to provide the power that punches, the effect of utilization water pump, can export the high pressure water, and then can utilize the high pressure water to strike sandy soil and accomplish the work that punches.

Barrel 2 in this embodiment all adopts the steel sheet to enclose barrel 2 that establishes and form, and this barrel 2 link up from top to bottom, and the diameter of barrel 2 is the same with the diameter that needs the pore-forming. In order to effectively guarantee the intensity of barrel 2, distribute along circumference between the outer wall of body 1 and the inner wall of barrel 2 and be provided with two piece at least bracing pieces 5.

The upper end of barrel 2 is connected on body 1, in order to avoid at the in-process that punches, and sand draws in barrel 2, and in this embodiment, the upper end of barrel 2 is connected on body 1 through many connecting rods 4. The convenient connection ground improves the structural stability of this tube well pore-forming device simultaneously, and connecting rod 4 radially inwards inclines gradually from bottom to top. In order to better cut into the soil and improve the hole forming efficiency, the lower part of the cylinder body 2 is provided with a blade part which can be cut into the soil.

The conical member 3 in this embodiment is a steel-supported conical member. The conical part 3 is connected at the lower end of the pipe body 1, the tip part is downward, a cavity communicated with the pipe body 1 is arranged in the conical part 3, and a main water outlet 31 communicated with the cavity is formed in the lower end of the conical part 3. In order to improve the hole forming efficiency and provide the power for the horizontal movement of the sand, the conical surface of the conical member 3 is provided with auxiliary water outlets 32 communicated with the cavity, in this embodiment, the conical surface of the conical member 3 is uniformly provided with a plurality of auxiliary water outlets 32 along the circumferential direction. In addition, the lower end of the cylinder 2 is higher than the lower end of the conical part 3.

For the operation of punching in order to make things convenient for, the fixed ligature in 1 upper end of body has action bars (not shown in the figure), and constructor can hand this action bars and carry out the operation of punching of tube well pore-forming device, and the operation is convenient more and laborsaving.

The operation method of the pipe well pore-forming device comprises the following steps: this tube well pore-forming device is small, the quality is light, and before the construction, a constructor will this tube well pore-forming device transport to the construction position, then connect the water pipe on tube well pore-forming device for the water pipe is connected with the water pump that provides power. After the beginning construction, the unblocked of water-flowing is guaranteed to the handheld water pipe of a constructor, and the action pole is handed to a constructor, and the sharp portion of conical part 3 is down, opens the water pump, and in trompil department in advance, the constructor circulates and lifts up the action of putting down pipe shaft pore-forming device slowly for barrel 2 cuts into to the sand in, and is along with slight rotation when lifting up putting down pipe shaft pore-forming device, improves the cutting force of barrel 2, improves the efficiency of punching. The water under high pressure that flows into in the body 1 gets into in the tapered part 3 and washes out from 3 main delivery ports 31 of tapered part, supplementary delivery port 32, and the water under high pressure of independently delivery port 31, supplementary delivery port 32 output erodees the sand from vertical and horizontal direction, realizes punching, and the high efficiency is realized punching under the cutting force effect of barrel 2 simultaneously to the aperture of pore-forming and the diameter phase-match of barrel 2, can be more accurate guarantee the pore-forming aperture, the pore-forming quality is higher.

The pipe well pore-forming device is small in size and light in weight, and can be carried easily by one person. When the water pump is used, the requirement on power is low, and only one water pipe is needed to be connected with the water pump. During the operation, can be under the condition of opening the water pump, with this tube well pore-forming device in trompil department in advance about assist with slight rotation operation can, the operation is very simple, and is low to artificial quantity and operating requirement, barrel 2 has improved the efficiency of pore-forming to the vertical cutting effect of sand simultaneously to can effectively guarantee the pore-forming diameter. And because the water pump can be located the far point position of the construction position of tube well pore-forming device, then this tube well pore-forming device's construction position near point does not relate to any power device, and is safe in utilization to because whole light in weight, do not have and empty the wounded danger. The pipe well pore-forming device is simple in structure, low in cost and high in working efficiency.
