Description

A device for manually digging piles

[technical field]

The utility model relates to the technical field of engineering construction, in particular to a manual hole-digging pile operating device.

[Background technique]

With the vigorous development of railways and highways in the country, manual hole-digging piles are more convenient in construction, faster in speed, and do not require large-scale machinery and equipment. , Impact cone punching, percussion drilling rig punching, rotary drilling rig drilling, and caisson foundations are all low, so they are widely used. However, due to the poor working conditions, harsh environment and high labor intensity of borehole piles, safety and quality are particularly important. Manual digging pile refers to the pile that is made by manual excavation, and then the steel cage is placed, and the concrete is poured. Existing artificial excavation piles have relatively high construction costs and are generally used in various complex geological conditions. However, due to the completion of the project, the construction personnel often ignore the quality of the retaining wall, which brings great safety risks; in addition, the excavation piles are underground The working conditions are poor and the environment is harsh. Construction workers have been in a limited space with a high dust concentration for a long time, which seriously threatens the health of personnel and even brings serious occupational diseases. Manual hole-digging piles are basically transported vertically by small winches, the upper and lower spaces are small, and there are many operations near the hole, which endangers the lives of underground workers. Therefore, with the continuous improvement of the degree of mechanization and the further increase of labor construction costs, it is particularly important to find a more convenient and safer construction method.

[utility model content]

The utility model mainly solves the problems of high labor intensity and high operation risk of manual hole-digging pile personnel, and provides a safe and convenient manual hole-digging pile operation device without increasing the cost.

In order to achieve the above-mentioned purpose, a kind of manual hole-digging pile operation device is designed, which includes a central operating platform and a guard plate. The central operating platform is composed of an upper steel plate, a lower steel plate, a guard plate and a channel steel. There is a channel-shaped steel between the lower steel plate, and the screw rod runs through the upper steel plate, the lower steel plate and the channel-shaped steel and is fixed to form a central operating platform. The central operating platform is square, and the four sides of the central operating platform are respectively connected with wrapping Axial swivel guard.

The operating device is provided with a rotary drilling rig, and the rotary drilling rig adopts round drills with different diameters, and the center of the round drill coincides with the center of the pile position.

The four corners of the central operation platform are respectively provided with suspension rings, and the steel wire rope passes through the suspension rings to fix the central operation platform under the hoist.

Compared with the prior art, the utility model has the advantages that the device is composed of a central operating platform and a guard plate, and the guard plate can be folded axially around the side of the central operating platform to form a protective tube that can protect the operator. To ensure the health and personal safety of personnel; to form holes through rotary drilling rigs, improve operating efficiency while reducing construction costs, and reduce labor intensity without increasing costs, thereby achieving certain economic benefits.

[detailed description]

Below in conjunction with accompanying drawing, the utility model is further described, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Figure 1 and Figure 2, the manual excavation pile operation device includes a central operating platform and a guard plate. The central operating platform is composed of an upper steel plate, a lower steel plate, a guard plate and a channel steel. The channel steel is clamped, and the screw runs through the upper steel plate, the lower steel plate and the channel steel and is fixed to form a central operating platform. The central operating platform is square, and the four sides of the central operating platform are respectively connected with protective plates that rotate around the sides in an axial direction. The operating device is provided with a rotary drilling rig, and the rotary drilling rig adopts round drill bits of different diameters, and the center of the round drill bit coincides with the center of the pile position. The four corners of the central operation platform are respectively provided with suspension rings, and the steel wire rope passes through the suspension rings to fix the central operation platform under the hoist.

The use process of this device is as follows:

1. Point setting out: Use the total station to accurately determine the four corners of the excavated pile and the centers corresponding to different circles, and do a good job of protecting the piles to ensure that the piles can be restored.

2. The hoist lifts the manual hole-digging pile operation device, and uses the rotary drilling rig to drill into the hole. The rotary drilling rig generally uses a round drill bit, and a combination of round drill bits with different diameters is used to replace the rectangle, thereby replacing the artificial hole. It is suitable for stone In the ground section, use the guard pile to restore the center of the pile position, and the drilling rig is in place. A special person is in charge of directing the rotary drilling rig to ensure that the center of the drill bit is aligned with the center of the pile position for drilling. During the drilling process, the operator observes whether the drill pipe is vertical at any time. At the beginning of drilling, low-speed drilling is adopted, and the wire rope of the main winch bears no less than 20% of the total weight of the drill pipe and drilling tools to ensure that the hole position does not deviate. Different drill bits should be selected according to different rock masses. It is advisable to construct the small-diameter drill bit first, and then construct the large-diameter drill bit.

3. Fold up the guard plates on the four sides of the central operating platform and fold the operating platform to ensure the safety of the workers during the construction of the retaining wall.

4. Pile core concrete pouring: Concrete is poured with string tubes. The diameter of the string tubes is 30cm, and the length of each section is within 1.5m. As the concrete is poured, the string tubes are removed section by section, and the concrete pouring height of each layer does not exceed 50cm, and is compacted layer by layer until the top of the pile.
