Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a grouting hole sealing device which is easy to install. Background Art

[0002] Cement grouting is an important construction method for foundation treatment, rock and soil or structural reinforcement in construction projects. When the geological conditions are poor and it is difficult to install the grouting plug or the anti-seepage requirements are high, the hole-sealing grouting method should be used. The so-called hole-sealing grouting method refers to the method of installing a hole pipe at the hole mouth, drilling and grouting in sections from top to bottom, and installing a hole sealer at the hole mouth to inject grouting into the grouting pipe for circulating grouting in each section.

[0003] In the past, hole-sealing grouting required welding a flange on the top of the embedded pipe or machining an internal thread. After drilling, the hole sealer was installed, and the grouting pipe was set up underneath for grouting. This method is widely used in China, but it has many disadvantages. The first method requires welding a flange on the top of each grouting embedded pipe. After the grouting of the entire grouting hole is completed, all welded flanges have no value for recycling, resulting in material waste and a safety hazard of electric shock during the welding process. The second method requires machining an internal thread on the top of each grouting embedded pipe. It is difficult to protect the thread intact during the drilling process. After drilling, the hole sealer is not installed firmly, leakage will occur during grouting, and the designed grouting pressure cannot be reached. Quality accidents such as cast pipes are prone to occur when pouring thick slurry.

[0004] Therefore, how to provide a simple-to-install grouting hole sealing device to solve the problem that the existing cement grouting hole sealing device cannot be reused is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0036] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please refer to Figure 1-Figure 4 Now, a simple installation grouting hole sealing device disclosed in the utility model is described. The utility model is composed of four parts, such as Figure 1 , including a liquid injection pipe 1, a plugging component 2, a clamping component 3 and a pre-buried steel pipe 4, the pre-buried steel pipe 4 is installed in the opening of the concrete layer, the concrete layer is placed above the rock layer, a casting hole is opened in the rock layer, one end of the clamping component 3 is inserted in the pre-buried steel pipe 4, the other end of the clamping component 3 is inserted in the plugging component 2, the liquid injection pipe 1 passes through the pre-buried steel pipe 4 and the clamping component 3, the bottom end of the liquid injection pipe 1 is set in the casting hole, the casting hole has the same diameter as the opening, and the outer surface of the pre-buried steel pipe 4 is attached to the opening. When the utility model is used, the pre-buried steel pipe 4 is first set in the opening, and then the plugging component 2 and the clamping component 3 are installed together, and finally the liquid injection pipe 1 is inserted in the hole between the plugging component 2 and the clamping component 3, and the cement grout is poured in the opening and the casting hole through the clamping limit of the plugging component 2 and the clamping device 3 to fill the cracks and pores in the rock and soil layer to achieve the effect of stabilizing the foundation.

[0038] In a specific embodiment, Figure 2 The clamping assembly 3 includes an installation conduit 31, a first clamping member 32, an extrusion member 33 and an installation shell 34. One end of the installation conduit 31 is clamped on the inner wall of the embedded steel pipe 4, and the other end is inserted into the plugging assembly 2. A hollow structure is formed between the installation conduit 31 and the embedded steel pipe 4. The first clamping member 32 is arranged in the hollow structure. A plurality of installation shells 34 are installed on the outer surface of the installation conduit 31. The installation shells 34 are arranged above the first clamping member 32. One end of a plurality of extrusion members 33 is arranged and installed in the installation shell 34, and the other end is arranged above the first clamping member 32. The length of the installation guide rail 31 is cut according to the construction site conditions. The first clamping member 32 is squeezed by the extrusion member 33 to expand the first clamping member 32 and fill the hollow structure to prevent grouting from flowing into the gap to affect the construction effect. Moreover, the expanded first clamping member 32 squeezes the embedded pipe 4 and the installation conduit 31, which can play a certain limiting effect.

[0039] In this embodiment, the first clamping member 32 uses a rubber spring, which is not only simple in structure but also low in cost and easy to replace.

[0040] Based on the previous embodiment, Figure 3 The extrusion member 33 includes a lifting motor 331, a lifting rod 332 and a push ring 333. The lifting motor 331 is installed in the installation housing 34, the lifting rod 332 is installed at the output end of the lifting motor 331, and the push ring 333 is installed at the bottom end of the lifting rod 332. The push ring 333 is connected in a transmission manner in the hollow structure. The lifting motor 331 drives the lifting rod 332 to move up and down, and the lifting rod 332 drives the push ring 333 to move up and down, so as to achieve the extrusion effect on the first clamping member 32. The use of electric extrusion can make the extrusion effect better and save labor costs.

[0041] In a specific embodiment, Figure 4 The plugging assembly 2 includes a gland 21, a second clamping member 22 and a sealing tee 23. The sealing tee 23 is provided with a liquid injection pipe 1, and the sealing tee 23 is provided with a sealing plate. The gland 21 is inserted at the upper end of the sealing tee 23. An installation space is formed between the gland 21, the sealing tee 23 and the sealing plate, and the second clamping member 22 is provided in the installation space. The second clamping member 22 has a different effect from the first clamping member 32. The second clamping member 22 is used to seal the orifice. By squeezing the gland 21, the second clamping member 22 fills the installation space, and then cooperates with the sealing plate to prevent the cement grouting from overflowing from the top. After being sealed with the second clamping member 22, the cement grouting can flow back through the side pipe of the sealing tee 23 for reuse.

[0042] In this embodiment, the second clamping member 22 is a rubber spring. The purpose of using the spring rubber is the same as that of using the spring rubber for the first clamping member 32.

[0043] In this embodiment, the sealing slurry return tee pipe 23 and the gland 21 are made of thick-walled seamless steel pipes. The use of seamless steel pipes can effectively prevent cement grouting from leaking from the gap.

[0044] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
