Description

Technical Field

[0002] In the field of geological exploration and civil engineering, soil drilling devices are indispensable key equipment, widely used in various scenarios such as pile foundation construction, geological survey, soil sampling, etc. However, the existing soil drilling technology faces a series of challenges in practical applications, among which the problem of pile hole collapse is particularly prominent, which seriously affects the construction efficiency and engineering safety.

[0003] Existing soil drilling devices mostly use traditional mechanical impact drilling, rotary drilling or static pressure soil drilling methods. These methods perform well in hard strata, but when dealing with soft soil, newly accumulated backfill soil, loose sand and other easily collapsed strata, it is often difficult to ensure the stability of the hole wall. Especially in areas with high groundwater levels, due to the lack of effective support for the hole wall, it is very easy to collapse or shrink during the drilling process. This not only increases the difficulty of construction, but may also lead to serious consequences such as equipment damage, personal injury and construction delay.

[0025] The control terminal is mobile.

[0026] Moreover, a method for using a soil drilling device comprises the following steps:

[0027] S1: Move the device to the work site to confirm the drilling position, lift the main frame with the lifting equipment, align the intersection of the diagonal lines of the base frame with the drilling position, and then align two pads and place them under the base frame. Then slowly lower the main frame and lower the base frame to contact the pads. Then, after the extension rod is extended outward to a certain extent, fix it to the ground with the fixer;

[0028] S2: The control end is manipulated to raise the drilling mechanism to the top through the transmission mechanism, and then one end of the guide tube is connected to the drill bit, and the guide tube is inserted into the protection barrel through the lower opening of the protection barrel. Then, the mobile vehicle connected to the support is moved to the guide tube through the control end until the ball contacts the bottom of the protection barrel, and the wire connected to the control end is removed. Then, the other end of the guide tube is slowly raised through the hoisting equipment, and after it is raised to a vertical position, it is sent to the main frame and aligned with the transmission head. Then, the drilling motor is operated through the control end, and the transmission head is threadedly connected to the guide tube through the operation of the drilling motor, and then the hoisting equipment is withdrawn, and the drilling motor stops running;

[0029] S3: After preparation, the control end is used to move the mobile vehicle connected to the drilling member in a direction away from the guide tube until the fixed wing is at a right angle to the drill body, and the stabilizing ring is installed on the drilling member through the fixing groove of the drill tooth plate, the fixing groove of the fixed wing, the transmission member slide groove and the fixing block;

[0030] S4: Then start the drilling motor to rotate the drill bit through the transmission head and the guide tube, then slowly lower the drilling mechanism through the transmission motor to start drilling, and start the mud suction device at the same time; after drilling to a certain extent, put the steel cage in the protection barrel and pour the poured concrete into the protection barrel from the upper end opening of the protection barrel through the concrete pump truck, and ensure that the concrete in the protection barrel is kept level with the ground when pouring the concrete;

[0031] S5: After drilling to the required depth, the upper end of the protection bucket is kept away from the ground, and the concrete level in the protection bucket is higher than the ground level;

[0032] S6: After drilling is completed, the mobile vehicle connected to the drilling member is moved toward the guide tube through the control end until the drilling member is completely retracted into the drilling member chute, and then the mobile vehicle connected to the support member is moved away from the guide tube. At this time, the stabilizing ring falls off the drilling member and falls to the bottom of the drilled hole. When the support plate of the support member is slowly recovered into the support member chute, the protective barrel above it falls downward. When the support member is completely recovered in the support member chute, the protective barrel falls to the bottom of the hole. At this time, the drill bit is in a fully recovered state, and the rising guide tube and the drill bit will be pulled out of the borehole through the drilling mechanism, and the next drilling and piling step is performed from this step.

[0033] The beneficial effects of the present invention are:

[0034] 1. In the present invention, the conventional drilling and subsequent pouring steps can be carried out simultaneously through the joint action of the drilling member, the support member and the protection barrel, thereby realizing the one-time operation of completing drilling and pouring simultaneously from drilling first and then pouring.

[0035] 2. In the present invention, the mobile vehicle moves up and down in the drilling member slide groove and the support member slide groove on the drill body, and the drill tooth plate and the support plate top plate connected thereto are movably connected to the drill body, so that the drilling member and the support member formed by the fixed wing and the support plate hinged to the drill tooth plate and the support plate top plate can be extended and recovered on the drill body; when extended, it can meet the drilling and supporting functions, and when recovered, it can meet the requirements of sliding the protective barrel and the concrete and steel cage inside it into the drilled hole, and then the guide tube and the drill bit can be retracted.

[0036] 3. In the present invention, the use of balls can keep the protection barrel abutting against the support plate in a stationary state at all times, thereby realizing the wall protection function of the protection barrel. At the same time, concrete is poured into the protection barrel when drilling, and the height difference between the horizontal surface of the concrete in the protection barrel and the ground level is controlled within a small range, which can prevent the pressure in the drilling hole from squeezing and deforming the protection barrel.

[0037] 4. In the present invention, the connection through the stabilizing ring can make the drilling member more firm and stable in drilling. BRIEF DESCRIPTION OF THE DRAWINGS
