Description

Technical Field

[0001] This invention relates to a foundation improvement device, and more specifically, to a foundation improvement device and process that improves the foundation by using a foundation improver and combining mechanical reinforcement materials with structures (buildings, underground structures, or retaining walls, etc.), and improves the workability of the continuous process of foundation improvement and reinforcement material installation by making the foundation improvement project and reinforcement material installation project continuous. Background Technology

[0002] This section provides background information related to the content of this application and is not necessarily prior art.

[0003] Soft foundations are saturated foundations such as clay, cement-soil, and organic soil. They have low strength, high compressibility, and low permeability, resulting in low bearing capacity, large lateral deformation, and an unstable state. Therefore, when constructing masonry structures, insufficient bearing capacity, foundation settlement, and lateral flow may occur, leading to foundation damage. Foundation improvement and reinforcement projects are often required.

[0004] As a general foundation improvement method, it is mainly applicable to foundation consolidation treatment and excavation replacement methods.

[0005] The traditional foundation consolidation process involves inserting a pressure bar into the weak foundation that needs improvement and reinforcement, raising and lowering it while rotating it, and simultaneously injecting a foundation conditioner to improve the foundation.

[0006] Patent No. 10-1977791 describes a method of connecting a foundation improvement device to an excavator to form a foundation improvement layer and connecting a document to a crane for construction. Different equipment is used for foundation improvement and document construction. As a result, problems arise from the use of two different types of heavy equipment, such as high rental and operating costs of heavy equipment and long time required to replace heavy equipment.

[0007] Patent No. 10-2091646 describes the following stages: excavating the foundation and digging the base; setting up two support walls at the excavation site; excavating downwards from the middle of the two foundation support walls and mixing the soil with a soil conditioner; installing a guide device on the inner side of the two support walls; and using the guide device to insert piles vertically into the soil mixed with the soil conditioner. The construction is carried out sequentially. The guide device includes a pair of cylindrical guide joints that are isolated from each other, a connector that connects the guide joints, and a support that places the guide joints on the two support walls. It does not include the technology that combines the pouring of the soil conditioner and the construction of piles.

[0011] (Patent Document 2) Registered Patent No. 10-2091646 Summary of the Invention

[0012] The problem that the invention aims to solve

[0013] This invention aims to solve the aforementioned problems by using a foundation conditioner to improve the foundation and combining mechanical reinforcement materials with structures (buildings, underground structures, or retaining walls, etc.) to improve the buoyancy stability of the structures. At the same time, through the sharing of equipment, it provides a continuous foundation improvement device and construction method for foundation conditioner injection and reinforcement material installation, which can quickly carry out foundation conditioner injection and reinforcement material installation projects.

[0014] means for solving problems

[0015] According to the present invention, a foundation improvement device capable of continuously injecting foundation conditioner and installing reinforcement materials is inserted underground as a rod for injecting foundation conditioner, curing agent, water, and air; characterized in that a foundation improvement layer is formed at the bottom of the rod by injecting foundation conditioner through the rod and connected by the rod, including a reinforcement material support for inserting the reinforcement material into the foundation improvement layer, the reinforcement material support obtaining air and expanding through an air supply means that sprays air into the ground through the rod, including an air inlet for clamping the head of the reinforcement material.

[0016] The rod consists of a first rod tube for pouring curing agent, a second rod tube for pouring water, and a third rod tube for pouring air, forming a triple tube structure. The air jack of the reinforcing material support expands by supplying air through the third rod tube, expelling the internal air.

[0017] It is worth mentioning that, compared with the injection position of the curing agent, the rod includes a cutting jet section that sprays water and air from the top to cut (stir, compress, stretch) mud and sand, a curing agent jet section that sprays curing agent from the bottom of the jet section, and an air curtain jet section that forms an air curtain between the cutting jet section and the curing agent jet section.

[0018] Invention Effects

[0019] According to the present invention, the foundation improvement device and process for continuously injecting foundation conditioner and installing reinforcement materials can connect the reinforcement materials to the rod for injecting foundation conditioner for installation. By sharing equipment, the operating cost of replacing equipment is reduced, the construction period is shortened, the project cost is reduced, and the effect of preventing problems before they occur is achieved.

[0020] Moreover, the air socket type, which consists of a support structure made of reinforced material, connects the air socket to the air path used in foundation improvement projects. It can be used without complicated additional configurations, realizing the miniaturization of the equipment and making it very easy to work with.

[0021] In addition, by pulling the foundation improvement device upwards, cutting mud and sand from the top, and spraying a curing agent in the cutting space to fill the smaller porosity of the curing agent, the strength of the foundation improvement layer can be improved, and an air curtain is formed at the bottom of the mud and sand cutting layer, so that the mud and sand do not sag and do not interfere with the spraying and curing of the curing agent below, thus increasing the strength of the foundation improvement layer while maintaining a high-quality effect.

[0039] In describing this invention, detailed descriptions of the functions or components of the invention will be omitted if it is believed that such descriptions might unnecessarily obscure the essence of the invention. Furthermore, the terms used below are defined for their functionality according to the invention and may vary depending on the intent or convention of the user or operator. Therefore, their definitions should be based on the entire contents of this listing.

[0040] Example 1 is a single type (integrated) of drill bit and reinforcement material support, and Example 2 is an independent type of drill bit and reinforcement material support.

[0041] <Implementation Example 1>

[0042] like Figure 1 As shown, the foundation improvement device 1000 in this embodiment can continuously inject foundation improver and install reinforcement materials, including injecting foundation improver (hardener, water, air) into the ground via a rod 100, forming the lower part of the rod 100, which is installed on a drill bit 200 for excavating the foundation, and reinforcement material 400 for installation in the ground. Figure 7 The reinforcement material 300 (not shown in the figure) is used.

[0043] The rod 100 is ideal, forming a triple tube structure composed of a first rod tube 110, a second rod tube 120, and a third rod tube 130 arranged from the inside out, with the first rod tube 110 arranged at the innermost part, the third rod tube 130 arranged at the outermost part, and the second rod tube 120 arranged in between. Of course, their arrangement can be reversed.

[0044] The first tube 110 utilizes its interior as a curing agent injection space, and obtains and delivers curing agent (cement slurry or mortar, etc.) from the curing agent supply means through the top gate.

[0045] The second rod tube 120 houses the first rod tube 110, and the space between the first rod tubes 110 serves as the water injection space, through which water from the supply means is delivered via the top.

[0046] The third rod tube 130 houses the second rod tube 120, and the space between the second rod tubes 120 serves as an air injection space. It receives and transmits air supplied from the air supply tool through the top.

[0047] The Rhodes 100 includes a first spray nozzle 131 for spraying water and air, a second spray nozzle 132 for spraying a curing agent, and an air curtain spray nozzle 133 for spraying air to form an air curtain.

[0048] The first jet nozzle 131 sprays water supplied by the second rod tube 120 and air supplied by the third rod tube 130, cutting away the surrounding mud and sand (cutting in this invention refers to pulverizing the mud and sand in the ground into very small pieces, forming pores through interference or compression (stretching), etc.), forming on the outer circumferential surface of the second rod tube 120. The water from the second tube 120 and the high-pressure air from the third rod 120 are sprayed onto the third rod with a radius of 100. Alternatively, it can be connected to the second rod tube 120 and the third rod tube 130 respectively, spraying water and air respectively, which mix outside the rod 100.

[0049] The second spray nozzle 132 is formed at the lower part of the first spray nozzle 131. It sprays the curing agent injected into the first rod tube 110 to the outer side of the rod 100 in the radial direction, replacing the mud and sand cut by the water and air sprayed by the first spray nozzle 131 to fill the pores.

[0050] The air curtain nozzle 133 between the first spray nozzle 131 and the second spray nozzle 132 is a plurality of spray holes (circular, polygonal, etc.) formed by the third rod tube 130 at intervals along the circumferential direction, forming an improved foundation of more than one section, in which the mud and sand cut by the first spray nozzle 131 will not fall off due to the hardening agent sprayed by the second spray nozzle 132.

[0051] The air curtain spray nozzle 133 consists of two sections, namely the first air curtain spray nozzle 133-1 and the second air curtain spray nozzle 133-2.

[0052] A first air curtain layer is formed by the first air curtain spray nozzle 133-1, and a second air curtain layer is formed by the second air curtain spray nozzle 133-2.

[0053] The first and second air curtain layers formed by the first air curtain spray nozzle 133-1 and the second air curtain spray nozzle 133-2 span the circumference of the rod 100 at different heights, forming a circular radial shape. The first air curtain layer formed by the first air curtain spray nozzle 133-1 is assisted by the second air curtain layer formed by the second air curtain spray nozzle 133-2, so that the overall air curtain layers formed above and below have no gaps.

[0054] According to the two-stage air curtain layer, the mud and sand passing through the first air curtain layer are isolated by the second air curtain layer to prevent them from falling.

[0055] At this point, the second air curtain nozzle 133-2 should ideally have a different spray power and center of gravity than the first air curtain nozzle 133-1, forming an interleaved structure. This will result in an overlap between the first and second air curtain layers, improving the air curtain effect.

[0056] The drill bit 200 includes drill positions 210 for drilling, for example, cylindrical, with a plurality of drill positions 210 formed in the circumferential direction.

[0057] In addition, the center of the drill bit 200 may include a jetting hole 220 for spraying hardener.

[0058] The drill bit 200 of this structure is fixed to the bottom of the rod 100 (by welding, bolts and nuts, sockets, etc.).

[0059] The spray nozzle 220 is considered to be one facing the bottom on the drawing, but is not limited to this. It may also include radial nozzles arranged in a position not interfered with by the reinforcing material support 300, spraying the hardener in a radial pattern.

[0060] The excavator head 200 can be a protective cover whose main purpose is to install the reinforcement material support 300, or it can be a protective cover that does not have an excavation position 210 and only provides space for installing the reinforcement material support 300.

[0061] When the foundation conditioner is injected, the reinforcement material bracket 300 does not prevent the hardener from being sprayed from the drill bit 200. When installing the reinforcement material, the reinforcement material should be fixed, preferably including an air jack 310 and a bracket plate 320.

[0062] The air jack 310 does not inject air or only injects a minimal amount of air during foundation improvement, and does not interfere with the injection of the curing agent. When the reinforcement material is installed after foundation improvement, it expands due to the injection of air, causing the support plate 320 to clamp and fix the surrounding part of the reinforcement material. It can be a single ring shape, or two semicircles arranged in a circular shape, etc.

[0063] The air jack 310 is configured to inject and expel air as necessary. The feature of this invention is that it improves the foundation by loading 100 air injection configuration without adding any additional configuration.

[0064] The third tube 130 is infused with air during the internal foundation improvement process, such as... Figure 2 As shown, the air jack 310 includes a leaking riser 311 and an opening / closing valve 312 that communicate with the interior of the third rod tube 130, i.e., the air injection space.

[0065] There is one or more air leakage risers 311, with one side opening communicating with the interior of the air jack 310, and the other side opening arranged inside the third rod tube 130 of the air space.

[0066] The switch valve 312 is installed at the other opening of the vent riser 311. The vent riser 311 can be opened in various ways, such as by manual operation by the operator (or by sensing and automatic control completed through foundation improvement), mechanical operation outside the rod 100, or operation by electrical and electronic connection.

[0067] As shown in the figure, the switching valve 312 is located inside the bottom of the circuit 100, but it is not limited to this. Alternatively, the vent pipe 311 can be wired along the circuit 100 and then extracted from the outside of the circuit 100 for application to the outside of the circuit 100.

[0068] In addition, the third pipe 130 is not limited to directly supplying air to the air space—the air leakage inlet pipe 311; it can also use the first pipe 110, which provides a relatively spacious space for the castable material.

[0069] The switch valve 312 only opens or closes the leaking riser 311. Forced air injection is achieved by an air injection device that forces air in (out) during foundation improvement.

[0070] When the switch valve 312 is composed of two or more air leakage risers 311, the same number can be achieved. Alternatively, when two or more air leakage risers 311 are combined into one, only one valve is applicable.

[0071] The support plate 320 is a protection to prevent the soft pores 310 from contacting the surrounding parts of the reinforcing material and being damaged when fixing the reinforcing material. The reinforcing material can be fixed under high pressure and is preferably made of metal (such as iron).

[0072] Furthermore, to prevent slippage of the support plate 320 between the surface and the reinforcing material, the inner side should include a textured structure, i.e., one or more protrusions 321. The protrusions 321 can firmly secure the reinforcing material even in the absence of a textured structure around it. If the surface of the reinforcing material (nail nail, steel bar, rebar, anchor point, rocker bolt, etc.) has a textured structure, it can be secured even more effectively.

[0073] The support plate 320 of this structure is formed by a curved cross section and is fixed at certain intervals along the circumferential direction on the inner surface of the airlock 310.

[0074] In addition, such as Figure 3 As shown, the bottom of the airlock 310 may include a reinforcing plate 330 to protect the airlock 310.

[0075] The reinforcement plate 330 is made of metal (such as iron) and does not interfere with the contraction and expansion of the air socket 310. It forms one or more fixed on the air socket 310 and prevents it from being torn by sharp objects in the ground during foundation improvement and reinforcement material installation.

[0076] The bracket plate 320 and the reinforcing plate 330 can also be integrated. In this case, the bracket plate 320 and the reinforcing plate 330 preferably include the edge where the inner surface and bottom surface of the air jack 310 are connected.

[0077] The bracket plate 320 and reinforcement plate 330 introduced so far are additional configurations. The reinforcement material bracket 300 can also be composed of air jacks 310.

[0078] In addition, other configurations of the protective airlock 310, such as Figure 4 As shown, the drill bit 200 includes a protective plate 230.

[0079] The protective plate (protective bag) 230 is a structure that protrudes from the inner surface of the drill bit 200. Its length is shorter than the width of the vent 310 when it expands, and its length covers the bottom of the vent 310 when it contracts.

[0080] The protective plate 230 of this structure also serves to prevent the lower part of the airlock 310 from falling off.

[0081] The protection plates 330 and 230 are examples of the protection components of the protective airlock 310.

[0082] In addition, even if the airlock 310 is damaged and causes air leakage, if the leakage amount is lower than the injection amount, the airlock 310 may expand and secure the reinforcing material. However, when the air injection is interrupted, the reinforcing material may fall off as the contraction proceeds. To prevent this from happening, a sensor for detecting the status of the airlock 310 may be included.

[0083] The sensor is an ideal pressure sensor used to detect the pressure of the air jack 310. This pressure sensor detects the pressure of the air jack 310 and transmits it to a controller on the ground. Operators use the controller to monitor the pressure of the air jack 310 to confirm its status. For example, if the air jack 310 maintains a certain pressure for a period of time, it is considered normal; otherwise, it is considered abnormal. This judgment can be made not only by operators but also through program comparison and result notification.

[0084] In addition, a vibrating screen can be used to ensure the hardener is properly applied, depending on the requirements.

[0085] According to the present invention, a foundation improvement method for continuous engineering of foundation amendment injection and reinforcement material installation is as follows.

[0086] 1. Prepare foundation improvement equipment (see...) Figure 5 ).

[0087] First, during the injection of the foundation conditioner, the pores 310 of the reinforcement material support 300 should be in a contracted state.

[0088] Connect rod 100 to heavy equipment to prepare foundation improvement device 1000.

[0089] 2. Inject foundation amendment (see...) Figure 6 , Figure 7 ).

[0090] like Figure 6 As shown, the foundation improvement device 1000 is excavated and inserted to a predetermined depth using the heavy equipment, rotated, and pulled upwards, spraying water and air using a first jet nozzle 131 formed on the upper part of the rod 100. The water and air sprayed by the first jet nozzle 131 will cut through the surrounding mud and sand.

[0091] Below the first nozzle 131, two staggered air curtain nozzles 133-1 and 133-2 spray air into two sections, forming two air curtain layers to prevent the cutting mud and sand from falling. The bottom air curtain layer and the top air curtain layer are offset at a certain angle. The cutting mud and sand passing through the top air curtain layer are blocked by the bottom air curtain layer, thus minimizing the mixing ratio of mud and sand with the curing agent (cement slurry or mortar).

[0092] The curing agent is sprayed in a circumferential direction using the second nozzle 132 to improve the cut soil layer. The curing agent sprayed using the second nozzle 132 fills the foundation.

[0093] If a vibrating body is used, the vibrating body will vibrate the curing agent filled at the bottom, forming a watertight compacted layer.

[0094] Furthermore, the present invention also includes an airless spray nozzle 133. Figure 7 An example is given where water and air are sprayed from above for cutting without forming an air curtain, and castable is injected from below.

[0095] 3. Reinstall reinforcement materials.

[0096] Let's go. Reinforcement material connections (see...) Figure 8 ).

[0097] After the foundation conditioner is injected, the foundation conditioner device 1000 is brought to the ground. The head (top) of the reinforcing material 400 is connected to the reinforcing material support 300. As previously described, the head of the reinforcing material 400 is inserted into the center of the air inlet 310 in its contracted state. The air leakage inlet pipe 311 is opened via the switch valve 312, and air is injected through the air injection device, allowing the air to flow into the air inlet pipe 311 into the air inlet 310. The airlock 310 expands while clamping the head of the reinforcing material 400, connecting the reinforcing material 400 to the foundation conditioner device 1000.

[0098] Insert reinforcement material (see) Figure 9 ).

[0099] The foundation improvement device 1000 is lowered using heavy equipment, and the reinforcement material 400 is inserted into the underground foundation improvement layer 500. At this time, the head of the reinforcement material 400 will protrude outside the foundation improvement layer 500.

[0100] Separation of reinforcement materials.

[0101] After the reinforcement material 400 is installed, air is drawn into the air injection hole 310 and then expelled. As a result, the air injection hole 310 will shrink and detach from the surrounding part of the reinforcement material 400, and will be in a state of mutual disengagement. The foundation improvement device 1000 will be lifted slightly upward and separated from the reinforcement material 400.

[0102] 4. Connection between reinforcement materials and structural foundation (see [link]). Figure 10 )

[0103] After tidying up the head of the reinforcement material 400, construct the foundation 600 of the structure (reinforcement, concrete pouring, etc.). At this time, connect the head of the reinforcement material 400 and the steel bars 610 of the foundation 600 (the connection varies depending on the structure; for example, a retaining wall can be connected to the horseshoe section). This integrates the structure with the foundation reinforcement 400 and the foundation improvement layer 500, achieving stabilization.

[0104] Figure 13 and Figure 14 This is an example drawing of a structure (underground structure 1, retaining wall 2) to which the present invention is applicable. The present invention is not limited to the example drawing and is applicable to a variety of structures.

[0105] <Implementation Example 2>

[0106] like Figure 11 and Figure 12 As shown, the foundation improvement device in this embodiment is a foundation improvement device capable of continuously injecting foundation improver and installing reinforcement materials. It is an independent type of drill bit 200 and reinforcement material support 300. When injecting foundation improver, only drill bit 200 is connected to rod 100 for use. Figure 11 After injecting the foundation conditioner, when inserting the reinforcement material 400, the drill bit 200 is separated from the rod 100 and the reinforcement material support 400 is connected in its position.

[0107] The reinforcement support 300 is a configuration connected to the rod 100 and includes a socket 340. The socket 340 is a cylindrical structure with an open bottom (or top) and an internal air vent 310, which includes conduits for injecting and venting air, and is fixed to the rod 100 by means of screws or the like.

[0108] The drill bit 200 also uses the same socket structure as the socket 340 of the reinforcing material bracket 300, and is assembled and disassembled onto the rod 100.

[0109] The connection between the drill bit 200 and the reinforcing material bracket 300 and the rod 100 is not limited to screws; various connection methods such as clamps can be used.

[0110] Furthermore, the assembly technology of the reinforcement material bracket 300 can also assemble the reinforcement material bracket 300 on the drill bit 200 without separating the drill bit 200 from the rod 100.
