Description

Technical Field

[0001] This application relates to the field of foundation reinforcement technology, and in particular to the foundation and construction method of water-related towers. Background Technology

[0002] In recent years, extensive research has been conducted both domestically and internationally in the field of geotechnical engineering to improve traditional anchor bolts and anchor heads. With the rapid development of geotechnical engineering, anchoring technology has become an important branch of the field, widely applied in slope protection, foundation pits, tunnels, dams, wharves, subways, underground space engineering, and tension foundations.

[0003] Currently, the most widely used anchor bolts are hollow steel pipes and reinforced mortar anchor bolts, which are bonded solely by cement mortar. This method is widely applicable when there are few gaps in ordinary soil layers. However, in actual operating environments such as overhead grouting and underwater grouting, such as in coastal areas where groundwater is highly corrosive, the reinforcing steel skeleton is extremely prone to corrosion. In engineering projects, the steel pipes and reinforcing steel bars in pipe pile foundations are coated with epoxy resin. The epoxy resin coating significantly reduces the bond strength between the steel pipes / reinforcing steel bars and the mortar. In corrosive environments, the reinforcing steel bars in the structure will still corrode, and at the point where the coating is damaged, the local corrosion development is faster than in areas without a coating. Under the action of flowing water, components in the mortar will be carried away, causing a decrease in mortar strength. Oxygen in the water causes the reinforcing steel bars to oxidize and expand, leading to a decrease in strength.

[0004] Therefore, when grouting underwater, if the gaps in the soil or water layer are large, it is difficult to fill the gaps completely, thus making it difficult to improve the anchoring performance. As a result, when common anchor structures are used in corrosive underground water-filled areas, the service life and performance of the foundation are usually greatly reduced. Summary of the Invention

[0005] Therefore, it is necessary to provide a water-resistant tower foundation and construction method to address the problem that when there are large gaps in the soil or water layer during underwater grouting, it is difficult to fill the gaps completely, thus making it difficult to improve the anchoring performance. As a result, the service life and performance of common anchor structures are usually greatly reduced when used in corrosive underground water-filled areas.

[0006] A water-prone tower foundation, the water-prone tower foundation comprising:

[0007] A sleeve, which is used to insert into a pile hole opened on the ground surface;

[0008] A sleeve is inserted into the sleeve, and a grouting cavity is formed between the sleeve and the sleeve. The grouting cavity is used to inject magnetic fiber mortar and magnetic mortar.

[0009] An electromagnet, which is inserted into the sleeve;

[0010] A support anchor rod is located inside the grouting cavity and extends out of the sleeve and is inserted into the bottom wall of the pile hole; the portion of the support anchor rod located inside the sleeve is connected to the outer wall of the sleeve.

[0011] In actual use and during grouting, the aforementioned water-related tower foundation involves injecting magnetic fiber mortar and magnetic mortar into the grouting cavity. Subsequently, an electromagnet is energized, generating a magnetic field around it. Under the influence of this magnetic field, the magnetic particles of waste slag and scrap iron in the magnetic fiber mortar and magnetic mortar align their magnetic moments and become magnetized, exhibiting strong magnetic attraction. Simultaneously, this causes the surrounding grout to tightly adhere and aggregate around the electromagnet, increasing the density of the anchor body. Larger magnetic particles experience greater magnetic force, increasing their density and causing them to sink with the grout, converging towards the electromagnet. The magnetic particles of varying sizes interlock, forming a dense whole centered on the electromagnet. Even under conditions of highly corrosive groundwater, groundwater cannot penetrate the structure and directly contact the internal materials. The contact design allows for a longer service life of the internal structure, effectively inhibiting material aging and ensuring engineering performance. Furthermore, in earthquake-prone areas where concrete is prone to cracking, or where severe cracks develop during the curing process due to expansion stress or other factors, an electromagnet can be placed again within the pre-installed sleeve. This secondary use of the electromagnet's strong adsorption effect on magnetic mortar and magnetic fiber mortar allows for crack repair and can be applied to the later maintenance of pile foundations. Simultaneously, the support anchor rod connects to the sleeve and is driven into the bottom wall of the pile hole, thus supporting the sleeve. After the magnetic mortar and magnetic fiber mortar solidify, the support anchor rod embeds into and tightly bonds with them, thereby strengthening the bond between the water-crossing tower foundation and the soil, making the water-crossing tower foundation more stable.

[0012] In one embodiment, the foundation of the water-crossing tower further includes an expansion anchor bolt located in an anchor hole opened in the side wall of the pile hole.

[0013] In one embodiment, the expansion anchor bolt includes a rod body and a waist beam. The rod body passes through the anchor hole, one end of the rod body is connected to the waist beam, and the waist beam abuts against the side wall of the pile hole and is located at the entrance of the anchor hole to limit the expansion anchor bolt.

[0014] In one embodiment, the expansion anchor is a hollow anchor used to inject the magnetic mortar.

[0015] In one embodiment, the expansion anchor bolt further includes a drill bit connected to the end of the anchor bolt away from the sleeve.

[0016] In one embodiment, the foundation of the water-crossing tower further includes multiple sets of expansion anchors, each set of expansion anchors comprising multiple expansion anchors; the multiple sets of expansion anchors are located at different depths of the pile hole, and the multiple expansion anchors in each set are arranged axially around the pile hole.

[0017] In one embodiment, the angle between the expansion anchor and the ground surface is 5°-15°, and the expansion anchor is inclined toward the side closer to the bottom wall of the pile hole.

[0018] In one embodiment, the foundation of the water-crossing tower further includes a fixing plate with fixing holes, the sleeve passing through the fixing holes and connected to the fixing plate, and one end of the support anchor rod being connected to the fixing plate.

[0019] In one embodiment, the fixing plate is connected to at least two support anchors.

[0020] In one embodiment, the foundation of the water-crossing tower further includes a control component, which includes: a main switch, an ammeter, a current regulator, an AC power supply, a gaussmeter, and wires;

[0021] The electromagnet, the main switch, the ammeter, the current regulator, and the AC power supply are connected in series via the wires.

[0022] The gaussmeter is connected to the power supply and is used to measure the magnetic field strength of the electromagnet.

[0023] In one embodiment, the ratio of cement, sand, magnetic particles, basalt fiber, and expansion agent in the magnetic fiber mortar poured at the bottom of the pile hole is 1:3:0.2:0.1:0.2;

[0024] The ratio of cement, sand, magnetic particles, and expansion agent in the magnetic mortar poured into the grouting cavity is 1:3:0.2:0.2.

[0025] One embodiment of this application also provides a construction method for a water-related tower foundation. The construction method for the water-related tower foundation includes the following steps:

[0026] The drilling location of the pile hole is determined in areas where groundwater is corrosive or where there is flowing groundwater.

[0027] Insert the sleeve into the pile hole;

[0028] The support anchor rod is connected to the sleeve, and the sleeve and the support anchor rod are inserted into the sleeve. The support anchor rod is inserted into the pile hole and into the bottom wall of the pile hole.

[0029] The electromagnet is inserted into the sleeve, and then energized to cause the electromagnet to generate a vibrating magnetic field under the action of alternating current.

[0030] Inject the magnetic fiber mortar and the magnetic mortar into the grouting cavity;

[0031] The electromagnet was recovered.

[0032] The above-described construction method for water-related tower foundations involves injecting magnetic fiber mortar and magnetic mortar into the grouting cavity. Subsequently, an electromagnet is energized, generating a magnetic field around it. Under the influence of this magnetic field, the magnetic particles of waste slag and scrap iron in the magnetic fiber mortar and magnetic mortar align their magnetic moments and become magnetized, exhibiting strong magnetic attraction. This attracts the surrounding grout to adhere tightly to the electromagnet, increasing the density of the anchor body. Larger magnetic particles experience greater magnetic force, increasing their density and causing them to sink with the grout, converging towards the electromagnet. The magnetic particles of varying sizes interlock, forming a dense whole centered on the electromagnet. Even under highly corrosive groundwater conditions, this prevents groundwater from penetrating the structure's interior. Direct material contact allows for a longer service life of the internal structure, effectively inhibiting material aging and ensuring engineering performance. Furthermore, in earthquake-prone areas where concrete is prone to cracking, or where severe cracks develop during the curing process due to expansion stress or other factors, an electromagnet can be placed again within the pre-installed sleeve. This secondary use of the electromagnet's strong adsorption effect on magnetic mortar and magnetic fiber mortar allows for crack repair and can be applied to the later maintenance of pile foundations. Simultaneously, the support anchor rod connects to the sleeve and is driven into the bottom wall of the pile hole, thus supporting the sleeve. After the magnetic mortar and magnetic fiber mortar solidify, the support anchor rod embeds into and tightly bonds with them, thereby strengthening the bond between the water-crossing tower foundation and the soil, making the water-crossing tower foundation more stable.

[0055] See Figure 1 , Figure 1 The diagram shows a structural schematic of a water-crossing tower foundation 100 according to an embodiment of this application. The water-crossing tower foundation 100 provided in an embodiment of this application includes: a sleeve 110, a pipe 120, an electromagnet 130, and a support anchor 140.

[0056] In the aforementioned water-related tower foundation 100, the drilling location of the pile hole 111 needs to be determined and the pile hole 111 drilled first in areas with corrosive groundwater or areas with flowing groundwater. A sleeve 110 is inserted into the pile hole 111 drilled on the ground surface. Subsequently, a casing 120 is inserted into the sleeve 110, forming a grouting cavity 121 between the sleeve 120 and the sleeve 110. The grouting cavity 121 is used to inject magnetic fiber mortar and magnetic mortar. The support anchor 140 is located within the grouting cavity 121 and extends beyond the sleeve 110, inserting into the bottom wall of the pile hole 111. The portion of the support anchor 140 located within the sleeve 110 is connected to the outer wall of the casing 120. An electromagnet 130 is then inserted into the casing 120.

[0057] In actual use and during grouting, the aforementioned water-resistant tower foundation 100 involves injecting magnetic fiber mortar and magnetic mortar into the grouting cavity 121. Subsequently, the electromagnet 130 is energized, generating a magnetic field around it. Under the influence of this magnetic field, the magnetic particles of waste slag and scrap iron in the magnetic fiber mortar and magnetic mortar align their magnetic moments and become magnetized, exhibiting strong magnetic attraction. Simultaneously, this causes the surrounding grout to tightly adhere and aggregate around the electromagnet 130, increasing the density of the anchor body. Larger magnetic particles experience greater magnetic force, increasing their density and causing them to sink with the grout, converging towards the electromagnet 130. The magnetic particles of varying sizes interlock, forming a dense whole centered on the electromagnet 130. Even under conditions of highly corrosive groundwater, the groundwater cannot penetrate the structure and directly contact the internal materials, allowing... The internal structure has a longer service life, effectively inhibits material aging, and ensures engineering performance. Furthermore, in earthquake-prone areas where concrete is prone to cracking, or where severe cracks occur during the curing process due to expansion stress or other factors, an electromagnet 130 can be placed again within the pre-reserved sleeve 110. The strong adsorption of the electromagnet 130 on the magnetic mortar and magnetic fiber mortar is then used for crack repair, which can be used for later maintenance of the pile foundation. Simultaneously, the support anchor 140 is connected to the sleeve 120 and driven into the bottom wall of the pile hole 111, thus supporting the sleeve 120. After the magnetic mortar and magnetic fiber mortar solidify, the support anchor 140 embeds into and tightly bonds with them, thereby strengthening the bond between the water-crossing tower foundation 100 and the soil and rock, making the water-crossing tower foundation 100 more stable.

[0058] Specifically, the inner wall of the pile hole 111 is serrated, which allows magnetic mortar to be injected between the side wall of the pile hole 111 and the outer wall of the sleeve 110. This increases the contact area between the side wall of the pile hole 111 and the magnetic mortar, thereby increasing the bond strength between the water-crossing tower foundation 100 and the surrounding soil and rock of the pile hole 111 and improving the frictional resistance between the side of the water-crossing tower foundation 100 and the soil and rock.

[0059] See Figure 8 Specifically, the electromagnet 130 consists of a coil 132 and an iron core 131. By adding an iron core 131 to the multi-turn ring coil 132, the magnetic induction intensity can be increased. The magnetic induction intensity can also be increased by changing the number of turns of the ring coil 132.

[0060] Specifically, an alternating current is passed through the electromagnet 130, which generates an oscillating magnetic field. This causes the magnetic mortar and magnetic fiber mortar particles to be acted upon by the magnetic field, converging towards the electromagnet 130 to generate a squeezing force, reducing porosity and making the resulting anchor solid structure more compact.

[0061] See Figure 2Specifically, the water-crossing tower foundation 100 includes multiple sleeves 120 and multiple electromagnets 130. The multiple sleeves 120 are axially arranged around the axis of the sleeve 110, which can be uniformly arranged, and will not be elaborated further.

[0062] Preferably, the number of sleeves 120 is 2 or 4.

[0063] Specifically, an enlarged head 112 is provided at the bottom of pile hole 111, which can reduce groundwater seepage from around the bottom of sleeve 110 after grouting. The resulting inverted T-shaped structure, formed by injecting magnetic mortar and magnetic fiber mortar and squeezing it outwards, increases the resistance of the water-crossing tower foundation 100 near the deep soil and rock. From a structural stress analysis perspective, this increases the moment of force and improves the uplift bearing capacity of the water-crossing tower foundation 100. The injection of magnetic fiber mortar into the enlarged head 112 improves the shear bearing capacity at the enlarged head 112, which is beneficial to the overall structural integrity.

[0064] Specifically, the water-crossing tower foundation 100 also includes a rubber plug. After the electromagnet 130 is inserted into the sleeve 120, the cable is extended, and then the opening of the sleeve 120 is blocked with a rubber plug to prevent magnetic mortar from entering the sleeve 120 and affecting the electromagnetic performance of the electromagnet 130.

[0065] In one embodiment, the water-crossing tower foundation 100 further includes an expansion anchor 150, which is located in an anchor hole 151 opened in the side wall of the pile hole 111. The expansion anchor 150 can reinforce the soil and rock around the pile hole 111 through the compressive force between the expansion anchor 150 and the anchor hole 151, thereby strengthening the integrity of the water-crossing tower foundation 100 and the surrounding soil and rock, diffusing soil and rock stress, increasing the compressive bearing capacity of the soil and rock, and improving the pull-out and overturning resistance of the water-crossing tower foundation 100. To a certain extent, it can avoid the influence of poor soil and rock on the engineering mechanical properties of the water-crossing tower foundation 100.

[0066] In one embodiment, the expansion anchor 150 includes a rod body 152 and a waist beam 153. The rod body 152 passes through the anchor hole 151, and one end of the rod body 152 is connected to the waist beam 153. The waist beam 153 abuts against the side wall of the pile hole 111 and is located at the entrance of the anchor hole 151 to limit the expansion anchor 150.

[0067] Specifically, the maximum inner diameter of the waist beam 153 is larger than the diameter of the anchor hole 151, so that it can be locked at the entrance of the pore to limit the expansion anchor 150.

[0068] In one embodiment, the expansion anchor 150 is a hollow anchor for injecting magnetic mortar, which allows the expansion anchor 150 to expand and press against the sidewall of the pore, thereby reinforcing the soil and rock around the pile hole 111.

[0069] Preferably, the sidewall of the anchor hole 151 is serrated, which allows magnetic mortar to be injected between the sidewall of the anchor hole 151 and the outer wall of the expansion anchor rod 150. This increases the contact area between the sidewall of the anchor hole 151 and the magnetic mortar, increases the compressive force between the expansion anchor rod 150 and the anchor hole 151, increases the compressive bearing capacity of the soil and rock, and improves the pull-out and overturning resistance of the water-crossing tower foundation 100.

[0070] See Figure 3 In one embodiment, the expansion anchor 150 further includes a drill bit 154 connected to the end of the anchor away from the sleeve 110, thereby enabling the expansion anchor 150 to be driven into the side wall of the pile hole 111 to form an anchor hole 151, or to be driven into the anchor hole 151 more easily.

[0071] In other embodiments, the anchor hole 151 can be drilled first by the drill bit 154 and left in the anchor hole 151, and then the expansion anchor rod 150 can be inserted into the anchor hole 151 and abut against the drill bit 154.

[0072] Specifically, the outer wall of the drill bit 154 is serrated, thus enabling it to drill serrated anchor holes 151.

[0073] In one embodiment, the water-crossing tower foundation 100 further includes multiple sets of expansion anchors 150, each set comprising a plurality of expansion anchors 150. The multiple sets of expansion anchors 150 are located at different depths of the pile hole 111. The plurality of expansion anchors 150 in each set are arranged axially around the pile hole 111, thereby reinforcing the soil and rock at different depths around the pile hole 111 and strengthening the integrity of the water-crossing tower foundation 100 with the surrounding soil and rock. Furthermore, based on the condition of the soil and rock around the pile hole 111, the plurality of expansion anchors 150 in each set at different depths are arranged axially around the pile hole 111 with different densities and spacing, thus specifically reinforcing the soil and rock at different depths around the pile hole 111.

[0074] Specifically, multiple expansion anchors 150 in each group of expansion anchors 150 are evenly arranged axially around the pile hole 111.

[0075] In one embodiment, the angle between the expansion anchor 150 and the ground surface is 5°-15°. The expansion anchor 150 is inclined to the side closer to the bottom wall of the pile hole 111. When the water-crossing tower foundation 100 is subjected to a pull-out force, the presence of the angle between the expansion anchor 150 and the ground surface makes it difficult for the soil and rock to separate, so that the expansion head 112 can be pulled out of the pile hole 111, thereby enhancing the pull-out resistance of the water-crossing tower foundation 100.

[0076] See Figure 4In one embodiment, the water-crossing tower foundation 100 further includes a fixing plate 141, the fixing plate 141 having a fixing hole 142, the sleeve 120 passing through the fixing hole 142 and connected to the fixing plate 141, and one end of the support anchor rod 140 being connected to the fixing plate 141, thereby enabling the anchor rod to be connected to the sleeve 120 through the fixing plate 141.

[0077] Specifically, the support anchor rod can be welded to the fixing plate, riveted, or fixedly connected to the fixing plate after passing through a hole opened in the fixing plate.

[0078] In one embodiment, the fixing plate 141 is connected to at least two support anchor rods 140.

[0079] See Figure 5 In one embodiment, the support anchor 140 is driven vertically into the bottom wall of the pile hole 111 along the direction of gravity.

[0080] See Figure 6 and Figure 7 In another embodiment, the support anchor rod 140 is driven into the bottom wall of the pile hole 111 at an angle of 5° to 15° with the vertical direction, wherein the orientation of multiple support anchor rods can be the same, different or opposite.

[0081] In another embodiment, the support anchor 140 is drilled vertically into the rock mass at the interface between different rock types, such as the strata, joints, or foliation surfaces.

[0082] In one embodiment, the water-crossing tower foundation 100 further includes a control component 160, which includes: a main switch 161, an ammeter 162, a current regulator 163, an AC power supply 164, a gaussmeter 165, and a conductor 166. The electromagnet 130, the main switch 161, the ammeter 162, the current regulator 163, and the AC power supply 164 are connected in series via the conductor 166 to provide alternating current. The gaussmeter 165 is connected to the power supply and is used to measure the magnetic field strength of the electromagnet 130. Adjusting the current regulator 163 regulates the magnetic induction intensity by adjusting the current magnitude. The gaussmeter 165 measures the magnetic field strength to ensure that the magnetic induction intensity in the grouting area is within the effective range of 1000~2000 gauss, so that magnetic materials and magnetic grout can be better attracted to the vicinity of the electromagnet 130 by the magnetic field force.

[0083] In one embodiment, the ratio of cement, sand, magnetic particles, basalt fiber, and expanding agent in the magnetic fiber mortar poured at the bottom of the pile hole 111 is 1:3:0.2:0.1:0.2, and the ratio of cement, sand, magnetic particles, and expanding agent in the magnetic mortar poured in the grouting cavity 121 is 1:3:0.2:0.2. Adding magnetic particles of different sizes to the injected grout increases the density of the larger particles, thus expelling groundwater. Larger magnetic particles experience greater attraction, increasing agglomeration and compressive force to densify the grout and effectively compressing pores in the water. Smaller magnetic particles can fill smaller pores, resulting in good gradation and continuous particle size curvature. Adding an expanding agent to the injected grout increases the lateral friction of the water-crossing tower foundation 100 at the pile body, increasing structural resistance.

[0084] Specifically, the magnetic particles are waste slag, waste carbon steel scrap, and iron scrap. The purpose is that, compared with nano magnetic particles, industrial iron-containing waste slag has stronger magnetism and adsorption after being magnetized under the action of a magnetic field. At the same time, it is green and environmentally friendly and can reduce costs.

[0085] Specifically, the magnetic particles are selected from one or more of the following: a bowl-shaped arc structure, a coiled rotating conical long tube spring shape, a semi-coiled shaving shape, etc. After the magnetic particles are added, they are evenly distributed and can drive the slurry to flow under the action of magnetic field force. They have a large specific surface area, a large contact area, a strong driving force, and a certain degree of interlocking, which can interlock with each other and is conducive to the dense structure.

[0086] One embodiment of this application also provides a construction method for a water-related tower foundation 100. The construction method for the water-related tower foundation 100 includes the following steps:

[0087] Determine the drilling location of pile hole 111 in areas where groundwater is corrosive or where there is flowing groundwater.

[0088] Insert the sleeve 110 into the pile hole 111.

[0089] The support anchor rod 140 is connected to the sleeve 120, and the sleeve 120 and the support anchor rod 140 are inserted into the sleeve 110. The support anchor rod 140 is inserted into the pile hole 111 and inserted into the bottom wall of the pile hole 111.

[0090] The electromagnet 130 is inserted into the sleeve 120, and then the electromagnet 130 is energized so that the electromagnet 130 generates a vibrating magnetic field under the action of alternating current.

[0091] Inject magnetic fiber mortar and magnetic mortar into the grouting cavity 121.

[0092] 130 electromagnets were recovered.

[0093] The water-crossing tower foundation 100 is constructed using the aforementioned construction method. Magnetic fiber mortar and magnetic mortar are injected into the grouting cavity 121. Subsequently, the electromagnet 130 is energized, causing it to generate a magnetic field. Under the influence of the magnetic field, the magnetic particles of waste slag and scrap iron in the magnetic fiber mortar and magnetic mortar tend to align and become magnetized, exhibiting strong magnetic attraction. Simultaneously, this causes the surrounding grout to tightly adhere and aggregate around the electromagnet 130, increasing the density of the anchor body. Larger magnetic particles experience greater magnetic force, increasing their density and causing them to sink with the grout, converging towards the electromagnet 130. Magnetic particles of varying sizes interlock, forming a dense whole centered on the electromagnet 130. Under conditions where groundwater is highly corrosive, groundwater cannot penetrate the structure and directly contact the internal materials. The contact design allows for a longer service life of the internal structure, effectively inhibiting material aging and ensuring engineering performance. Furthermore, in earthquake-prone areas where concrete is prone to cracking, or where severe cracks occur during the curing process due to expansion stress or other factors, an electromagnet 130 can be placed again within the pre-reserved sleeve 110. The strong adsorption of the electromagnet 130 on the magnetic mortar and magnetic fiber mortar is then used for crack repair, which can be used for later maintenance of the pile foundation. Simultaneously, the support anchor 140 is connected to the sleeve 120 and driven into the bottom wall of the pile hole 111, thus supporting the sleeve 120. After the magnetic mortar and magnetic fiber mortar solidify, the support anchor 140 embeds into and tightly bonds with them, thereby strengthening the bond between the water-crossing tower foundation 100 and the soil and rock, making the water-crossing tower foundation 100 more stable.

[0094] Specifically, the electromagnet 130 is directly embedded inside the sleeve 120.

[0095] In another embodiment, after grouting is completed, the electromagnet 130 is demagnetized, the rubber plug is removed, and the electromagnet 130 is taken out from the sleeve 120. The rubber plug is then replaced at the opening of the sleeve 120. In areas where concrete is prone to cracking, or where the structure develops severe cracks due to expansion stress or other factors during the setting process, the rubber plug can be opened, and the electromagnet 130 can be placed back into the reserved sleeve 110. The strong adsorption effect of the electromagnet 130 on magnetic mortar and magnetic fiber mortar can be used for crack repair for a second time. This method can be used for the later maintenance of pile foundations.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
