Description

Technical Field

[0001] The utility model relates to the technical field of sealing a grouting hole, in particular to a sealing casing device for a drilling grouting hole. Background Art

[0002] The drilling grouting hole sealing casing device usually refers to the grouting sealer, which is a grouting pipe grouting equipment used in underground engineering. It is mainly used to reinforce and seal the borehole wall by grouting after the drilling is completed to prevent groundwater leakage or soil collapse.

[0003] At present, the traditional drilling grouting hole sealing casing device cannot realize the rapid disassembly and connection between the device and the grouting pipe, which increases the time required for connecting the grouting pipe, reduces work efficiency, and thus increases manpower and material costs. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art that the device and the grouting pipe cannot be quickly disassembled and connected, which reduces work efficiency and increases manpower and material costs, and proposes a drilling grouting hole sealing casing device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A drilling grouting hole sealing casing device, comprising:

[0007] A casing body, wherein a tee-tube is detachably connected to the top of the casing body, a slurry outlet is provided at the bottom of the casing body, and a limiting ring is fixedly provided above the slurry outlet on the outside of the casing body;

[0008] A connecting assembly is arranged on the tee pipe and is used for connecting the device to the grouting pipe. The connecting assembly includes a lower connecting frame fixedly arranged below the lateral pipe opening of the tee pipe, an upper connecting frame is hingedly arranged on one side of the lower connecting frame, and openings are provided on the same side of the lower connecting frame. A threaded rod is rotatably arranged inside the opening of the lower connecting frame, and a locking knob is threadedly connected to the outside of the threaded rod.

[0009] In a possible design, a sealing gasket is fixedly provided on the inner wall on the same side of the lower connecting frame and the upper connecting frame, and a protrusion is provided on the outer side of the two sealing gaskets.

[0010] In a possible design, the top end of the three-way pipe is fixedly connected to a pressure gauge.

[0011] In one possible design, a rubber expansion plug is sleeved on the outside of the casing body above the limit ring, an I-shaped bracket is sleeved on the outside of the casing body above the rubber expansion plug, a rubber expansion plug is sleeved on the outside of the casing body above the I-shaped bracket, a rubber expansion plug is sleeved on the outside of the casing body above the I-shaped bracket, and a rubber expansion plug is sleeved on the outside of the casing body above the rubber expansion plug.

[0012] In a possible design, a swivel seat is rotatably provided at the top of the second I-shaped support frame, and the swivel seat is threadedly connected to the outer surface of the sleeve body. The outer ring of the swivel seat is annularly fixed with four swivel rods, and the outside of the four swivel rods are fixedly provided with anti-slip handles.

[0013] In the present application, when starting to use, first check whether all parts of the drilling and grouting hole sealing casing device are intact, then prepare the grouting pipe, and ensure that the size of the grouting pipe matches the size of the connecting component, and then on the outside of the casing body, starting from the top of the limit ring, sequentially set the rubber expansion plug 1, I-shaped bracket 1, rubber expansion plug 2 and I-shaped bracket 2, and the I-shaped bracket 2 is inserted together with the swivel seat when it is put in, and then the staff holds the non-slip handle to rotate the rotating rod, and the rotating rod rotates while driving the swivel seat to rotate synchronously, so that the swivel seat drives the I-shaped bracket 2 to move downward until it fits with the rubber expansion plug 2, and then inserts the casing body into the pre-prepared drilled hole to ensure that the bottom of the casing body The slurry outlet is located at the grouting position, and then the staff holds the non-slip handle again to rotate the rotating rod to drive the rotating seat to rotate. While the rotating seat rotates, it drives the I-shaped support frame 2 to rotate synchronously, and it moves downward along the outside of the casing body. While the I-shaped support frame 2 moves downward, a compressive force is formed on the rubber expansion plug 2. When the rubber expansion plug 2 is subjected to the compressive force, the compressive force is transmitted to the I-shaped support frame 1, and the compressive force on the I-shaped support frame 1 is then transmitted to the rubber expansion plug 1, so that the rubber expansion plug 1 is offset against the limit ring. When the rubber expansion plug 2 and the rubber expansion plug 1 are subjected to the compressive force, they will expand and stretch, and fit tightly against the borehole wall to form an effective closure, thereby sealing the borehole to prevent back-slurry.

[0014] Then take out the grouting pipe, turn the locking knob to disengage it from the abutment with the upper connecting frame, then open the upper connecting frame and insert the pipe mouth of the grouting pipe into the lower connecting frame, and ensure that the pipe mouth of the grouting pipe is located between the sealing gasket and the lower connecting frame, then rotate the upper connecting frame so that the upper connecting frame is stuck into the pipe mouth of the upper part of the grouting pipe, and also ensure that the pipe mouth of the grouting pipe is located between the sealing gasket and the upper connecting frame, then turn the locking knob, and the locking knob will drive the threaded rod to be stuck into the opening of the upper connecting frame while rotating, and then rotate the locking knob so that its bottom will abut against the upper connecting frame, so that the lower connecting frame and the upper connecting frame clamp the grouting pipe inward. In the process of grouting, observe the reading of the pressure gauge to ensure that the grouting pressure is within a safe range. According to the needs of the project, control the grouting amount and grouting speed until the predetermined grouting effect is achieved. When the grouting is completed, turn off the grouting equipment, wait for the grouting liquid to solidify, rotate the locking knob, loosen the lower connecting frame and the upper connecting frame, and take the grouting pipe out of the connecting assembly.

[0015] The utility model has the following beneficial effects:

[0016] The utility model discloses a method for quickly disassembling and assembling a grouting pipe by setting a connection component, opening the upper connection frame, inserting the pipe opening of the grouting pipe into the lower connection frame, rotating the upper connection frame, ensuring that the pipe opening of the grouting pipe is located between the sealing pad and the upper and lower connection frames, rotating the locking knob, and using the threaded rod to cooperate with the opening of the upper connection frame to achieve rapid locking, thereby achieving rapid disassembly and assembly connection between the device and the grouting pipe. The whole process does not require complicated tools or skills, thereby improving work efficiency and reducing manpower and material costs.

[0017] In the utility model, by arranging structures such as the rubber expansion plug 1, the I-shaped support frame 1, the rubber expansion plug 2, the I-shaped support frame 2, the rotating seat and the rotating rod, the movement of the rotating seat will push the I-shaped support frame 2 downward, thereby forming a compressive force on the rubber expansion plug 2, and the compressive force on the rubber expansion plug 2 will be transmitted to the I-shaped support frame 1, and then transmitted to the rubber expansion plug 1. When the rubber expansion plug 1 and the rubber expansion plug 2 are subjected to the compressive force, they expand and stretch open, and fit tightly with the borehole wall, thereby realizing the rapid expansion of the rubber expansion plug and the sealing of the borehole, thereby improving the work efficiency. At the same time, the effective sealing can prevent the back-slurry phenomenon in the grouting process, thereby ensuring the grouting quality and engineering safety.

[0018] The arrangement of the connection assembly of the utility model realizes the rapid disassembly and assembly connection between the device and the grouting pipe, reduces the time required for connecting the grouting pipe, improves the work efficiency, and thus reduces the manpower and material costs.
