Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, especially relates to an oval carrier and a combined carrier. BACKGROUND

[0002] The pull-pressure composite anti-floating anchor is gradually applied in engineering, especially in the anti-floating engineering field, due to its unique technical advantages. Engineering practice shows that when the pull-pressure composite anti-floating anchor is applied in the anti-floating anchor engineering, the anti-floating anchor is a vertical anchor, and the rod body of the pull-pressure composite anti-floating anchor is provided with a carrier. When the stratum where the anchor is located is prone to hole collapse, and the sand content or coarse particle content is high, the slag is prone to accumulate on the carrier.

[0003] In addition, during the on-site drilling construction and grouting construction process, the movement of the mechanical equipment and the dragging of the grouting pipe also cause the slag at the hole to fall into the drilling hole and be deposited on the carrier. These reasons cause the slag to accumulate above the carrier, further make the grouting body difficult to be compacted and solidified locally, and finally cause the compressive strength of the grouting body at the pressure-bearing carrier to be significantly reduced, so that the pressure-bearing anchoring segment and the tension anchoring segment cannot be cooperatively loaded, and the pull-pressure composite anti-floating anchor is greatly weakened in the anti-pulling load capacity. In order to solve the above-mentioned problems caused by the special stratum or the non-strict on-site construction, it is urgent to improve and optimize the carrier. CONTENT OF THE UTILITY MODEL

[0012] (2) The oval bearing body adopts a convex surface design, when part of the slag falls into the drill hole and falls on the end face of the oval bearing body, it is easy to slide off from the convex surface, avoiding accumulation; in addition, the oval bearing body adopts a convex surface, which has a certain extrusion and splitting effect on the grouting body, and under the strong constraint of the spiral rib, the compressive bearing capacity of the grouting body can be improved;

[0081] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. The technical features designed in different embodiments of the present application can be combined with each other as long as they do not conflict with each other. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without making creative labor fall within the scope of protection of the present application.

[0082] In the description of the utility model, it needs to explain, the utility model uses all the terms (including technical terms and scientific terms) have same meaning with the meaning that the ordinary skill in the art to which the utility model belongs generally understands, cannot be understood as the limitation of the utility model;It should be further understood that the terms used by the utility model should be understood as having the same meaning as the meaning of these terms in the context of the specification and related fields, and should not be understood in an idealized or overly formal sense, except as expressly defined in the utility model.

[0083] Embodiment one

[0084] The utility model provides a kind of oval carrier 230, as shown in Figure 1 And Figure 2 It includes fixedly connected bearing plate 231 and bearing cap 232, the plane of bearing plate 231 is perpendicular to the axial normal line of bearing cap 232, bearing cap 232 is arranged at the bottom surface center of bearing plate 231, bearing plate 231 and bearing cap 232 are opened with the through tendon hole 233 that communicates, and the horizontal section of bearing plate 231 is oval.

[0085] Specific implementation, as shown in Figure 2 And Figure 3 The horizontal section of the bearing plate 231 of the oval carrier 230 is oval, and the horizontal section of the bearing cap 232 is circular or hexagonal.The oval carrier 230 is fixed to the threaded steel bar 110 through the through tendon hole 233, the bearing plate 231 is arranged upward towards the drill hole 104, the bearing plate 231 of the oval carrier 230 has a small bearing area, which can significantly reduce the risk of slag accumulation on the carrier, in combination with the strong constraint of the spiral rib, so that the grouting body 105 at the installation position of the carrier will not have the phenomenon of insufficient compressive bearing capacity, ensuring the safety of anchoring engineering.

[0086] Further, as shown in Figures 4 to 12 The upper surface of the bearing plate 231 is a convex surface 234.Specifically, if the bearing plate 231 is a plane, the design of the oval shape cannot completely avoid the residual slag on the upper surface of the bearing plate 231, and the upper surface of the bearing plate 231 is designed as a convex surface 234, so that the slag generated during construction will naturally fall along the convex surface 234 and will not remain on the surface of the bearing plate 231, further ensuring the safety of anchoring construction.In an embodiment, the convex surface 234 is a slope convex surface 234b or a spherical convex surface 234a symmetric about the major axis of the upper surface of the bearing plate 231.Specifically, the slope convex surface 234b is as shown in Figure 4 And Figure 9 The cross section of the short axis of the oval carrier 230 of the slope convex surface 234b is triangular;The spherical convex surface 234a is as shown in Figure 10 、 Figure 11 AndFigure 12 As shown in the drawings, the cross section of the short axis of the elliptical carrier 230 of the spherical convex surface 234a is hemispherical.

[0087] In an embodiment, the inner wall of the rebar hole 233 is provided with internal threads. Specifically, the outer surface of the threaded rebar 110 is provided with external threads, the inside of the rebar hole 233 is provided with internal threads, and the external threads of the outer surface of the threaded rebar 110 are threadedly connected with the internal threads of the inside of the rebar hole 233, thereby ensuring the stability of the installation of the elliptical carrier 230.

[0088] Embodiment Two

[0089] During construction, it is necessary to install a grouting pipe to inject grout. However, the elliptical carrier 230 provided in the embodiment cannot have a pipe hole on the surface of the bearing plate 231 for fixing the grouting pipe due to the small area of the bearing plate 231. However, in actual construction, the grouting pipe must be fixed to ensure its safety.

[0090] To solve the above technical problems, as shown in the drawings, the utility model provides a combined carrier 235, which comprises two elliptical carriers 230 as in embodiment one, namely a first elliptical carrier 235a and a second elliptical carrier 235b. The first elliptical carrier 235a is arranged near the upper part of the drill hole 104, and the second elliptical carrier 235b is arranged below the first elliptical carrier 235a. The angle θ formed by the long axis of the bearing plate 231 of the first elliptical carrier 235a and the long axis of the bearing plate 231 of the second elliptical carrier 235b is in the range of 0° < θ ≤ 90°. Figure 33 Specifically, when the angle θ formed by the long axis of the bearing plate 231 of the first elliptical carrier 235a and the long axis of the bearing plate 231 of the second elliptical carrier 235b is equal to 90°, the first elliptical carrier 235a and the second elliptical carrier 235b are orthogonal. When the angle θ formed by the long axis of the bearing plate 231 of the first elliptical carrier 235a and the long axis of the bearing plate 231 of the second elliptical carrier 235b is less than 90°, the first elliptical carrier 235a and the second elliptical carrier 235b are oblique. Clamping the grouting pipe in the middle of the included angle formed by the orthogonal or oblique first elliptical carrier 235a and the second elliptical carrier 235b can avoid opening a hole on the bearing plate 231. At the same time, two elliptical carriers 230 can further decompose the pressure at the elliptical carrier 230 compared to one elliptical carrier 230, thereby reducing the compressive stress of the grouting body 105 at the elliptical carrier 230.

[0091] Embodiment Three

[0092]

[0093] ​At the drilling hole 104 of the anti-floating anchor rod at the designed position, the interface is formed between the cushion layer and the basement floor, the interface is formed between the cushion layer and the foundation soil, and the grouting at the hole is easy to produce floating slurry, the underground water is easy to form seepage channels in the horizontal direction and the vertical direction at the interface, the threaded steel 110 is corroded by water, the tensile strength is reduced, the engineering accident is induced, and the basement floating accident is caused.

[0094] To solve the above technical problems, as shown in Figure 13 , Figure 14 and Figure 15 The utility model provides a water stop ring 240 for anti-floating anchor rod, including upper ring pipe 241, lower ring pipe 242 and ring plate 243, upper ring pipe 241 is located above ring plate 243, lower ring pipe 242 is located below ring plate 243, ring plate 243 is set with ring plate hole 243a, and upper ring pipe 241 and lower ring pipe 242 are hollow and form upper ring hole 241a and lower ring hole 242a, and the normal axis of upper ring hole 241a, ring plate hole 243a and lower ring hole 242a coincides.

[0095] Specifically, when the normal axis coincides, the plane of the ring plate 243 is vertically arranged with the upper ring pipe 241 and the lower ring pipe 242. The water stop ring 240 is embedded between the floor 100 and the drilling hole 104, and the floor 100 and the drilling hole 104 are also provided with a cushion layer 103, the ring plate 243 abuts on the cushion layer 103, and the threaded steel 110 is placed in the drilling hole after passing through the upper ring hole 241a, the ring plate hole 243a and the lower ring hole 242a. The sidewall of the upper ring pipe 241 and the lower ring pipe 242 can effectively prevent the underground water from permeating between the floor 100 and the cushion layer 103, and between the cushion layer 103 and the soil layer of the drilling hole 104, avoiding the corrosion of the steel bar.

[0096] Preferably, as shown in Figure 13 and Figure 16 The diameter of the upper ring hole 241a is the same as or smaller than the diameter of the ring plate hole 243a and the lower ring hole 242a.

[0097] In actual drilling hole 104 operation, although the drilling hole 104 has a designed depth, to prevent the spoil from depositing at the bottom of the hole and causing the steel bar to be unable to be inserted, the actual drilling hole 104 generally exceeds the length of the anchor rod. To ensure the anchoring length of the threaded steel 110 in the floor, the threaded steel 110 needs to be suspended inside the drilling hole, at which time two horizontal suspension steels 247 need to be installed at the top of the drilling hole 104, the two horizontal suspension steels 247 bind and clamp the threaded steel 110, so that when the drilling hole 104 is too deep, the threaded steel 110 can also be ensured not to fall into the drilling hole 104, and the anchoring length of the threaded steel 110 in the floor inside is ensured to meet the design requirements.

[0098] In order to install the horizontal hanging rib 247, as shown in Figure 17 、 Figure 18 and Figure 19 , the embodiment is provided with a sleeve pipe 244 on the basis of the first embodiment, the sleeve pipe 244 is installed outside the upper ring pipe 241, the upper ring pipe 241 is symmetrically provided with a hanging rib setting groove 245, as shown in Figure 20 and Figure 21 , the sleeve pipe 244 is symmetrically provided with a hanging rib cover hole 246, and the hanging rib cover hole 246 is arranged opposite to the hanging rib setting groove 245.

[0099] In specific implementation, as shown in Figure 22 、 Figure 23 and Figure 24 , the diameters of the required fixed threaded steel bars 110 are quite different, and the diameters of the threaded steel bars 110 required by different geological environments are also different, therefore, the hanging rib setting groove 245 is provided in the upper ring pipe 241, the hanging rib setting groove 245 abuts against the ring plate 243, and the width of the hanging rib setting groove 245 can match the diameter requirement of different threaded steel bars 110, so that the horizontal hanging rib 247 can be stably installed and abut against the ring plate. Preferably, the shape of the hanging rib setting groove 245 is rectangular, and the rectangular shape can be more conducive to the placement of the threaded steel bar 110.

[0100] In an embodiment, as shown in Figure 17 、 Figure 18 , the sleeve pipe 244 is sleeved outside the upper ring pipe 241 and detachably connected with the water stop ring 240, the sleeve pipe 244 includes a horizontal plate 244a and a vertical plate 244b perpendicular to each other, the hanging rib cover hole 246 is arranged at the bottom of the vertical plate 244b, the hole opening of the hanging rib cover hole 246 can completely match the cross section of the horizontal hanging rib 247, and the distance between the hanging rib cover holes 246 can be determined according to the diameter of the threaded steel bar 110. The hanging rib setting groove of the upper ring pipe 241 cooperates with the hanging rib cover hole 246 of the sleeve pipe 244, which can match the installation requirement of different types of steel bars, and at the same time, the mold of the upper ring pipe 241 does not need to be additionally provided, but only the sleeve pipe 244 needs to be produced according to different requirements, thereby greatly reducing the cost.

[0101] Preferably, as shown in Figure 21 , the shape of the hanging rib cover hole 246 is a groove or a semicircle. Specifically, the cross section of the threaded steel bar 110 is generally circular, and the hanging rib cover hole 246 is provided in the shape of a groove or a semicircle, which can better adapt to the threaded steel bar 110.

[0102] The utility model also provides a kind of anti-floating anchor rod, as shown in Figure 25 , including the water stop ring for the anti-floating anchor rod described in any one of the above.

[0103] The utility model also provides a kind of construction method for the water stop ring of anti-floating anchor rod, which comprises the following steps:

[0104] S1. After the drilling of the hole 104 is completed, the water stop ring 240 is installed at the opening of the hole 104. When the anchor rod body is hoisted above the water stop ring 240, the collar tube 244 is removed.

[0105] S2. Lower the anchor rod body from the annular hole of the water stop ring 240 to the designed depth. The horizontal hanging rod 247 is just inserted into the hanging rod installation groove 245 of the upper ring tube 241 and abuts against the ring plate 243.

[0106] S3. Put the sleeve tube 244 on the outer side of the upper ring plate 243 so that the hanger cover holes 246 are respectively clamped on the horizontal hanger bars 247;

[0107] S4. Inject cement slurry into the borehole 104 and add slurry until the upper ring pipe 241 is filled with cement slurry.

[0108] Specific construction methods: Figure 25 As shown, after the construction of the borehole 104 is completed, the water stop ring 240 is installed at the hole mouth of the borehole 104, the anchor rod body is hoisted above the water stop ring 240, and the anchor rod body is lowered from the ring hole of the water stop ring 240 to a preset depth; the transverse hanging bar 247 is inserted into the hanging bar installation groove 245 of the upper ring tube 241, and abutted against the ring plate 243. The transverse hanging bar 247 fixes the anchor rod body at the preset depth, which not only ensures the inner depth of the anchor rod body in the borehole, but also ensures the anchoring length of the threaded steel bar 110 in the base plate; the sleeve tube 244 is sleeved on the outside of the upper ring tube 241, so that the hanging bar cover holes 246 are respectively stuck on the transverse hanging bar 247; cement slurry is injected into the borehole 104, and the slurry is added until the upper ring tube 241 is filled with cement slurry.

[0109] Example 4

[0110] The utility model provides an assembled bracket for anti-floating anchor rods, such as Figure 26 、 Figure 27 and Figure 28 As shown, it includes a first bracket member 260a, a second bracket member 260b and a connecting member 267. The first bracket member 260a and the second bracket member 260b are symmetrical in shape, and the connecting member 267 connects the first bracket member 260a and the second bracket member 260b symmetrically and detachably. The first bracket member 260a and the second bracket member 260b both include an end face 261 and a rib arc surface 265. The rib arc surface 265 is vertically connected to the bottom of the end face 261. The rib arc surface 265 of the first bracket member 260a and the rib arc surface 265 of the second bracket member 260b are spliced ​​to form a rib groove, and the rib groove is set at the center of the spliced ​​end faces 261 of the first bracket member 260a and the second bracket member 260b.

[0111] In actual implementation, the bottom of the end face 261 is provided with a semicircular rib arc surface 265 with a certain length, and the rib arc surfaces 265 of the first support member 260a and the second support member 260b are spliced to form a rib groove for placing the threaded steel bar 110, which is arranged at the center of the end face 261. The first support member 260a and the second support member 260b are symmetrical in shape, and when the fabricated support 260 needs to be installed, the first support member 260a and the second support member 260b are directly spliced at the designed position of the fabricated support 260 of the threaded steel bar 110, the rib arc surfaces 265 are buckled on the threaded steel bar 110, and the first support member 260a and the second support member 260b are symmetrically and detachably connected through the connecting member 267, which greatly simplifies the construction intensity and avoids damage to the anticorrosive coating of the threaded steel bar 110.

[0112] Preferably, the shape of the end face 261 of the first support member 260a and the second support member 260b after splicing is an ellipse. Specifically, the shape of the end face 261 of the first support member 260a and the second support member 260b after splicing is an ellipse, which reduces the cross-sectional area of the fabricated support 260 in the drill hole 104, increases the area of the gap between the end face 261 and the drill hole 104, and avoids excessive cross-sectional area from blocking the grouting body 105.

The shape of the pipe groove 266 is a semicircular notch, which can well adapt to the shape of the grouting pipe. When the grouting pipe is installed, the pipe groove 266 clamps the grouting pipe to ensure the installation direction of the grouting pipe as a whole and the accuracy of the installation position of the grouting pipe.

[0135] The elliptical supporting body 230 includes a supporting plate 231 and a supporting cap 232 fixedly connected. The supporting plate 231 and the supporting cap 232 are provided with through-rib holes 233 . The horizontal cross-section of the supporting plate 231 is elliptical, and a convex surface 234 is provided on the surface of the supporting plate 231 .

[0136] In one embodiment, if Figure 40 As shown, the anchoring device 200 includes a first nut 201 and a first steel plate 202. The first steel plate 202 is vertically connected to the first nut 201. The first steel plate 202 and the first nut 201 are provided with a connected first reinforcement hole 203. The inner wall of the first reinforcement hole 203 forms an internal thread 225, which is threadedly connected to the external thread of the threaded steel bar 110.

[0137] In one embodiment, if Figure 32 As shown, when the pull-out bearing capacity is less than a preset value, the threaded steel bar 110 is installed with an elliptical bearing body 230 as described in Example 1. Specifically, when the pull-out bearing capacity of the tension-compression composite anti-floating anchor is low, such as when the pull-out bearing capacity characteristic value does not exceed 350kN, a single elliptical bearing body can be used. It should be noted that the pull-out bearing capacity characteristic value is not limited to the above-mentioned 350kN and can also be determined based on the specific construction conditions.

[0138] In one embodiment, if Figure 33As shown, when the uplift bearing capacity is greater than the preset value, the combined bearing body 235 as described in Embodiment Two is installed along the threaded steel bar 110 at a preset distance in the axial direction, and the second isolation sleeve 111b is sleeved between the two oval bearing bodies 230 of the combined bearing body 2235, and the length of the second isolation sleeve 111b is the same as the preset distance between the two oval bearing bodies 230.

[0139] Specifically, when the uplift bearing capacity of the pull-pressure composite anti-floating anchor is high, such as the characteristic value of the uplift bearing capacity exceeding 350 kN, the combined bearing body 235 can be used, which includes two oval bearing bodies 230 arranged in an upper-lower interval and cross manner, such as a preset interval of 0.5 m-1.0 m, to further reduce the pressure on the grouting body 105 at the bearing body, to ensure that the bearing body does not be damaged under pressure, and to improve the safety of the pull-pressure composite anti-floating anchor. It should be noted that the characteristic value of the uplift bearing capacity is not limited to 350 kN, but can be determined according to the specific construction condition.

[0142] Specifically, the outer side of the oval bearing body 230 is sleeved with a spiral rib 113, and the diameter of the spiral rib 113 is greater than the length of the long axis of the oval bearing body 230. Since the top surface of the bearing plate 231 of the oval bearing body 230 is a slope surface or a spherical surface symmetrical along the long axis, when the grouting body 105 is extruded, it will have a splitting effect on the grouting body 105. The oval bearing body 230 is sleeved with a spiral rib 113 on the outer side, which has a strong transverse or radial constraint effect on the grouting body 105, significantly improves the compressive bearing capacity of the grouting body 105, thereby fully ensuring the cooperative bearing of the pressure-anchoring section 108 and the tension-anchoring section 109, and greatly improving the uplift bearing capacity of the pull-pressure composite anti-floating anchor.

[0159] (2) A second isolation sleeve 111b with a length equal to the preset interval length of the first and second oval-shaped carriers 235a and 235b is made, and the second isolation sleeve 111b is set on the threaded steel bar 110, with the bottom of the second isolation sleeve 111b abutting against the top of the second oval-shaped carrier 235b.

[0160] Specifically, the second isolation sleeve 111b is installed on the top of the second oval-shaped carrier 235b, and the length of the second isolation sleeve 111b is equal to the interval of the first and second oval-shaped carriers 235a and 235b.

[0161] (3) The first oval-shaped carrier 235a is installed, so that the long axis of the first oval-shaped carrier 235a and the long axis of the second oval-shaped carrier 235b form a preset angle on the projection plane, and the bottom of the first oval-shaped carrier 235a abuts against the top of the second isolation sleeve 111b.

[0162] Specifically, the first oval-shaped carrier 235a is continuously installed, so that the long axis of the bearing plate 231 of the first oval-shaped carrier 235a and the long axis of the bearing plate 231 of the second oval-shaped carrier 235b form an included angle θ, and the value of the included angle θ is in the range of 0°<θ≤90°.

[0165] Specifically, the assembled support 260 is installed below the second oval-shaped carrier 235b, and the end cap 250 is installed at the bottom of the threaded steel bar 110.

[0166] It should be noted that the number of assembled supports 260 is not limited to one, and can be two, three or more, which is determined according to the specific construction condition, and is not limited to the bottom of the second oval bearing body 235b, and the assembled support 260 can also be installed above the first oval bearing body 235a.

[0167] (6) After drilling the hole 104 to the preset elevation, the anchor rod body processed is hoisted and placed, and the water stop ring 240 is installed and centered at the hole 104.

[0168] Specifically, the hole 104 is drilled at the preset position, and after the hole 104 is drilled to the preset elevation, the assembled anchor rod is placed into the hole 104 to the preset depth, and the water stop ring 240 is sleeved at the hole, so that the ring plate of the water stop ring 240 is placed on the cushion layer 103.

[0169] Preferably, a steel pipe can also be sleeved from the top of the threaded steel bar 110, and after the steel pipe passes through the upper ring hole and the lower ring hole of the water stop ring 240, it abuts against the assembled support 260 and protrudes from the upper ring pipe of the water stop ring 240.

[0170] (7) The cement slurry is continuously injected into the hole 104 through the first grouting pipe 106 until the grouting liquid continuously overflows at the hole, and after a preset interval of time, the grouting is carried out through the second grouting pipe 107, and the grouting is stopped after reaching the preset requirement.

[0171] Specifically, the grouting is carried out through the first grouting pipe 106, and the grouting is stopped after the hole continuously returns the slurry, and the secondary grouting is carried out through the second grouting pipe 107 after a preset interval of time.

[0172] Subsequently, prestressed tensioning and bottom plate 100 construction are carried out, the strength of the grouting body 105 reaches the preset requirement, the counterforce frame is installed on the cushion layer 103, the threaded steel bar 110 is tensioned by using the through center jack, so that the tension reaches the preset requirement; the waterproof roll 102 is laid on the cushion layer 103 to form a waterproof layer, and the waterproof roll 102 is overlapped on the ring plate of the water stop ring 240; then the protective layer 101 is poured on the waterproof roll 102, and then the anchoring device 200 is installed, and the bottom plate 100 is constructed. By installing the anchoring device 200, the anchoring force of the threaded steel bar 110 in the bottom plate 100 is increased.

[0173] It should be noted that the pullout bearing capacity characteristic value of the two kinds of pull-push composite anti-floating anchor rods described above can be 350KN, but is not limited to 350KN, and can be determined according to the specific construction condition.

[0174] After the adoption of the present application, the following positive effects can be achieved under the conditions of sandy soil stratum, bulk weathered rock stratum, easy-collapsing hole stratum, and adverse site environment:

[0175] (1) The phenomenon of slag accumulation above the bearing body can be significantly reduced or even completely eliminated. The traditional bearing body is circular, and has a large cross-sectional area. When slag is generated above the bearing body, it will be deposited there due to the obstruction, causing the local grouting body 105 to be loose and the compressive bearing capacity to be severely insufficient. The present application adopts an elliptical bearing body 230, which has a significantly reduced cross-sectional area, and the top surface of the bearing plate 231 is in the form of a slope or a sphere. When slag is deposited above the bearing body, part of the slag will sink to the bottom of the borehole 104 through the large pores between the elliptical bearing body 230 and the borehole 104, and part of the slag that falls on the bearing plate 231 will slide down due to the special slope or spherical surface and then fall to the bottom of the borehole 104. Therefore, the elliptical bearing body 230 with a slope or spherical bearing plate 231 can effectively prevent slag from accumulating above the bearing body.

[0176] (2) The compressive bearing capacity of the grouting body at the bearing body is greatly improved. The elliptical bearing body 230 of the present application is externally sleeved with a spiral rib 113, and the diameter of the spiral rib 113 is greater than the length of the major axis of the elliptical bearing body 230. Since the top surface of the bearing plate 231 of the elliptical bearing body 230 is a slope or a sphere that is symmetrical along the major axis, it will have a splitting effect on the grouting body 105 when it is extruded. The external sleeve of the spiral rib 113 on the elliptical bearing body 230 will have a strong transverse or radial restraining effect on the grouting body 105, significantly improving the compressive bearing capacity of the grouting body 105, thereby fully guaranteeing the cooperative bearing of the pressure-anchoring section 108 and the tension-anchoring section 109 and greatly improving the uplift bearing capacity of the tension-compression composite anti-floating anchor.

[0177] (3) The centering effect of the tension-compression composite anti-floating anchor body is fully guaranteed. The bottom of the tension-compression composite anti-floating anchor is provided with an end cap 250. After the anchor body is lowered to the bottom of the borehole 104, the diameter of the end cap 250 forms a protective layer, so that the anchor body is in a centered state in the borehole 104, guaranteeing the bonding effect of the tension-anchoring section 109 and the grouting body 105.

[0178] (4) When the uplift bearing capacity of the tension-compression composite anti-floating anchor is high, such as when the characteristic value of the uplift bearing capacity exceeds the preset value, two elliptical bearing bodies 230 can be arranged in an upper-lower interval and cross arrangement, such as an interval of 0.5m-1.0m, to further reduce the pressure on the grouting body 105 at the bearing body and guarantee that the bearing body does not fail under pressure, with the aim of improving the safety of the tension-compression composite anti-floating anchor.

[0179] (5) The waterproof effect of the pull-push composite anti-floating anchor rod hole is greatly improved, and the construction is very convenient. After the pull-push composite anti-floating anchor rod is lowered into the drill hole 104, a water stop ring 240 is installed at the hole. Since the upper cylinder and the lower cylinder of the water stop ring 240 are connected into a whole with the ring plate, and the lower cylinder of the water stop ring 240 extends into the drill hole 104, the seepage channel of the underground water at the junction of the hole ground and the cushion 103 in the horizontal direction is blocked. The ring plate of the water stop ring 240 is pressed on the ground or the cushion 103 of the hole, and the waterproof roll material 102 is laid above, blocking the seepage channel of the underground water at the junction of the hole ground and the cushion 103 in the vertical direction. The upper cylinder is higher than the waterproof roll material 102, further preventing the residual water at the interface between the waterproof roll material 102 and the bottom plate 100 from seeping in the horizontal direction. And the threaded steel bar 110 at the hole is provided with an isolation sleeve. In summary, the application of the water stop ring 240 greatly improves the water stop effect, even completely eliminates the potential waterproof failure risk of the traditional waterproof process, and greatly simplifies the cumbersome construction process such as traditional welding and lapping.
