The method for providing tensile bearing capacity by utilizing deep soil is an important design construction method used in civil engineering and water conservancy engineering, and is mainly applied to anchor rod technology, anchor plate technology, uplift foundation, anchor ingot and other foundation forms needing to provide tensile bearing capacity in foundation pit and side slope engineering. The core idea of the anchor rod technology is to drive a slender rod body into a deep rock-soil body, provide tensile bearing capacity through the connection of the rod body, an anchoring body and the rock-soil body, and transmit through the rod body. The anchor rod technology has the advantages of high construction speed and low cost, and is widely applied to civil engineering and water conservancy engineering. The anchor rod mainly provides the uplift bearing capacity by side friction resistance, and a reaming anchor rod technology is also provided, namely, a reaming section is designed in the anchor rod, and partial end resistance is provided as a part of the uplift bearing capacity.

In order to improve the bearing capacity of the anchor rod, a plate-shaped member is embedded in backfill soil, and the pulling-resistant bearing capacity provided by the plate-shaped member is transmitted by using a tensile member, which is called an anchor plate structure in civil engineering. The anchor plate structure has high bearing capacity, but the tensile member and the anchor plate are embedded in the soil body after being connected, so that the application possibility is generally only available in the backfill soil. In addition, the uplift pile mainly utilizes the friction force between the rock-soil body and the pile body to provide the uplift bearing capacity, and the uplift bearing capacity of the uplift pile is improved by utilizing the expanded head in the bottom-expanded uplift piles in various forms, but the uplift bearing capacity of the deep rock-soil body is still not fully utilized. How to better utilize the uplift bearing potential of deep rock mass or soil mass, how to thoroughly eliminate useless solid residues in the rock mass or soil mass after construction is finished, purify underground space, realize the recycling of solid materials, and have great engineering practice significance and environmental protection benefit.

The anchored member is a member requiring tension action, and in this embodiment, the anchored member may be a soil retaining member in a foundation pit or a slope support, an anchor in a bridge structure, a bridge abutment in the bridge structure, a dam in a hydraulic structure, a port dock, a high-rise building (structure), or the like. These structures need to provide horizontal or oblique tension to resist overturning and sliding, so as to maintain the stress balance of the anchored member and keep the structure stable. The anti-floating structure requires a downward pulling force to balance the buoyancy, and therefore, may be one of the anchored members. In some cases it may occur that one or a combination of the above elements provides a pulling force, such as a dock requires both a pulling force to resist flotation and to resist skidding and overturning. That is, any member that needs to provide a tensile force by using a rock body or a soil body can be used as the anchored member in the embodiment. In this embodiment, the anchored member may be various soil retaining members used in foundation pit support, such as underground continuous wall, steel reinforced cement soil mixing wall, row pile, etc., and when row pile is used, a cement soil mixing wall waterproof curtain is often arranged outside the row pile for water stop, as shown in fig. 1 and fig. 2. In this embodiment, the anchored member may be a steel pipe pile continuous wall soil retaining member in foundation support (that is, a continuous wall body composed of a steel pipe pile and a connecting body provided between the steel pipe piles and having a soil retaining or water stopping function). In this embodiment, the anchoring barrel is a hollow tubular member for providing a construction operation surface for connecting the anchoring barrel, and the anchoring barrel can provide an anchoring force by using a rock mass or a soil mass on the periphery of the anchoring barrel. The anchoring cylinder can be vertically, horizontally or obliquely placed in the rock body or the soil body. In this embodiment, the anchoring cylinder may be a steel pipe pile, or may be various tubular passages constructed in a rock mass or a soil mass, such as a pile position hole with a stable side wall, a horizontally or obliquely excavated passage in the rock mass or the soil mass, and the like. When the steel pipe pile is used as the anchoring cylinder, the rock mass or the soil mass in the steel pipe pile is removed, so that an operation surface connected with the anchoring cylinder can be formed, and the anchoring force is provided. The construction is quick, and the recycling is easy. In this embodiment, one of the main purposes of the anchoring cylinder is to provide an operation surface for the construction of the anchoring cylinder connection, and after the anchoring cylinder connection construction is completed, one or more combinations of concrete, reinforced concrete, cement paste or mortar, and resin can be filled in the anchoring cylinder without recovering the anchoring cylinder, so as to improve the bearing capacity of the anchoring cylinder and increase the bearing capacity of the anchoring cylinder connection. In this embodiment, the tension member is a member having a tensile load-bearing capacity, which is buried in the rock mass or the soil mass, and one end of which is connected to the anchored member and the other end of which is connected to the anchoring cylinder, and the tension member passes through the side wall of the anchoring cylinder in the rock mass or the soil mass and extends to the hollow portion of the anchoring cylinder. In this embodiment, the tension member may be one or a combination of several of a steel strand, a high-strength fiber, a carbon fiber, a steel bar, and a steel pipe, and in this embodiment, the tension member has a sufficient tensile load-bearing capacity and can satisfy the requirement of deformation control. In this embodiment, the deformation control requirements of the anchored member can be met by prestressing the tension members. In this embodiment, the tension member may be placed at an angle so as to be higher at the side of the member to be anchored and lower at the side of the anchoring cylinder, so that the deep rock or soil can be sufficiently utilized to provide anchoring force. In this embodiment, the anchored members are connected as a member or a combination of members that securely connect the tension member with the anchored member, and the anchoring sleeve is connected as a member or a combination of members that securely connect the tension member with the anchoring sleeve. In this embodiment, when the anchoring cylinder anchoring structure is used in a foundation pit supporting project and the tension member is a steel strand, the anchored member connection may be configured as shown in fig. 1, 2 and 3, and the anchored member connection includes three parts of an anchor, an anchor backing plate and a waist beam, wherein the anchor backing plate is formed by welding a plurality of steel plates through welding seams; the anchoring barrel connection consists of two parts of an anchorage device and an anchorage device backing plate, as shown in figures 1, 2 and 4. In this embodiment, when the tension member is made of a high-strength flexible material such as carbon fiber cloth, the tension member, the anchored member and the anchoring cylinder may be connected to each other by bonding to form an anchored member connection and an anchoring cylinder, and a material such as bar-planting glue or epoxy resin may be used as the high-strength bonding material. The following part of this embodiment, with reference to fig. 1 to 4, describes the construction method and the specific implementation steps of the anchoring cylinder anchoring structure of the present invention. Firstly, constructing a hollow tubular member in a rock body or a soil body to be used as an anchoring cylinder, and removing the rock body or the soil body near the connecting position of the anchoring cylinder in the anchoring cylinder to form a construction operation surface required by the connection of the anchoring cylinder. In this embodiment, the steel pipe pile may be constructed as an anchoring cylinder, and the bottom of the steel pipe pile may be sealed during construction, so that after the construction of the steel pipe pile is completed, the rock or soil mass inside the steel pipe pile may be used as a construction operation surface for connection of the anchoring cylinder. In this embodiment, after the steel pipe pile is inserted into the rock mass or soil mass, the rock mass or soil mass connected to the anchoring cylinder in the steel pipe pile may be removed to form a construction work plane connected to the anchoring cylinder. In this embodiment, the anchoring cylinder may be constructed in other manners in the rock or soil, for example, a hole whose sidewall does not collapse is formed as the anchoring cylinder in the rock or soil, or a pipe may be buried in the rock or soil as the anchoring cylinder, for example, a vertical shaft is constructed in the rock or soil, then a pipe jacking or shield construction is performed in the deep rock or soil by using the vertical shaft, and both the constructed underground passage and the constructed vertical shaft may be used as the anchoring cylinder. And finishing the first step and entering the second step. In this step, a tunnel for passing through the tension member is constructed in a rock or soil body between the anchored member and the anchoring cylinder from one side of the anchored member by one or a combination of drilling, vibration, hammering or static pressure construction. In this step, the tension member construction may be completed with reference to the anchor rod construction method. If a member with certain rigidity, such as a steel pipe, is used as the tension member, the tension member can be directly made to pass through a rock body or a soil body by vibration, static pressure or hammering and other construction methods; or drilling holes in the rock or soil body, inserting steel pipes and the like, and then penetrating the tension member through the rock or soil body through the hole channel. In this embodiment, after the tension member passes through the rock mass or the soil mass, the steel pipe inserted into the rock mass or the soil mass can be pulled out for reuse, and meanwhile, the solid residue in the rock mass or the soil mass can be conveniently cleaned. And finishing the second step and entering the third step. In this step, when the cell passage for the tension member to pass through constructed in the above-mentioned second step reaches or passes through the side wall of the anchoring cylinder, it is necessary to determine the position of the intersection point with the side wall of the anchoring cylinder, and in this step, it is necessary to determine whether the cell passage for the tension member to pass through intersects with the side wall of the anchoring cylinder, and only if the cell passage for the tension member to pass through intersects with the side wall of the anchoring cylinder, the tension member can pass through the side wall of the anchoring cylinder into the anchoring cylinder, and the position of the intersection point can be determined by using the following method: increasing or decreasing the temperature near the intersection point between the anchoring cylinder constructed in the first step and the duct constructed in the second step by using a temperature changing device placed in the duct constructed in the second step, changing a temperature field near the intersection point, then measuring the temperature of the side wall of the anchoring cylinder near the intersection point between the anchoring cylinder and the duct or observing the change of the side wall of the anchoring cylinder caused by the temperature change in the anchoring cylinder, and then determining the position of the highest temperature point or the lowest temperature point of the side wall of the anchoring cylinder as the specific position of the intersection point; if the duct for the tension member to pass through does not intersect with the side wall of the anchoring cylinder in this step, it means that the construction of the second step does not meet the requirements, and the second step is required to be returned for the new construction. Thereby completing the third step and proceeding to the fourth step. In this step, holes are formed in the sidewall of the anchoring cylinder near the intersections of the sidewall of the anchoring cylinder and the tension members or the cells for the passage of the tension members. In this step, a core drill may be used to drill through the sidewall of the anchoring cylinder, or a hole may be drilled in the sidewall of the anchoring cylinder by crushing, cutting, or the like. In the step, a hole pressure reaction force construction method can be adopted to carry out water stop construction at the opening of the side wall of the anchoring cylinder, namely, a flexible sealing bag is adopted to surround and seal the opening of the side wall of the anchoring cylinder, a cutting device is positioned in the sealed flexible sealing bag, then the side wall of the anchoring cylinder is cut in the flexible sealing bag, the tension member penetrates through the side wall of the anchoring cylinder, then an underground water plugging structure tightly combined with the tension member is formed through the flexible sealing bag, and the cutting or crushing equipment is taken out. In this step, a water stop pad having a water stop function may be placed at the opening of the side wall of the anchoring cylinder. The water stop pad can be made of materials with quick condensation property such as quick-hardening cement and the like to timely block gaps, and can also be made of elastic rubber pads and the like to block water leakage positions. And finishing the fourth step and entering the fifth step. In the step, one end of the tension member passes through the side wall of the anchoring cylinder and enters the anchoring cylinder; and placing the other end of the tension member near the anchored member so that the tension member has a condition of being connected with the anchored member. In this step, the same method as in the fourth step described above may be used to perform the water stop construction at the opening of the side wall of the anchor cylinder. When the construction of the tubular member in the rock body or the soil body is used as the tension member for passing through the tunnel in the aforementioned step, the tension member may be placed in the tunnel in this step. In this step, the crossing construction of the tension member may also be completed in such a manner that: the tension member passing through the sidewall of the anchoring cylinder is bent and extended to the upper portion of the anchoring cylinder, the connection member between the tension member and the anchoring cylinder is installed near the upper portion of the anchoring cylinder, and then the tension member extending into the anchoring cylinder is returned to the side of the anchored member until the tight and firm connection between the tension member and the anchoring cylinder is achieved. The advantage of installing in this way is that the anchoring cylinder can be filled with water, thereby avoiding the loss of underground water and the water stop work at the opening of the side wall of the anchoring cylinder, and realizing the installation work of connecting the tension member and the anchoring cylinder under water. And finishing the fifth step and entering the sixth step. In this step, the two ends of the tension member are respectively and firmly connected with the anchoring cylinder and the anchored member, and the connection construction of the anchoring cylinder and the anchored member is completed. After the step, after the connection of the anchoring cylinder and the connection construction of the anchored member, when the construction method of the anchoring structure of the anchoring cylinder is used for foundation pit supporting engineering, a foundation pit can be excavated and an underground structure is constructed, then the foundation pit is backfilled, the connection of the anchored member is dismantled, and the anchoring cylinder and the tension member are recovered together through drawing the anchoring cylinder for construction, so that the full recovery and reutilization of the anchoring structure of the anchoring cylinder are realized. In this step, in order to control the displacement of the anchored member, a prestress may be applied to the tension member in a pretensioning manner, and the anchored member may be real-time displacement-controlled by tensioning the tension member in real time in the anchoring cylinder during the use of the anchored member. In this step, the hollow part of the anchoring cylinder can be filled with one or a combination of several of concrete, reinforced concrete, cement paste or mortar, and resin as required to improve the bearing capacity of the anchoring cylinder and the connection of the anchoring cylinder.
