[0002] Anti-slide piles are piles that penetrate the landslide body and extend deep into the sliding bed. They are used to support the sliding force of the sliding body and stabilize the slope. They are one of the main anti-slide treatment measures and are widely used. However, due to the lack of consideration in the design of anti-slide piles, heavy rainstorms, and drastic changes in the environment where the landslide body is located, abnormal conditions in the anti-slide pile structure often occur, such as tilting of the pile body, cracking of the connecting beam and retaining plate, etc., which urgently need to be reinforced. Summary of the invention
[0003] The purpose of the present invention is to provide a reinforced concrete diagonal brace structure reinforced with anti-slide piles and a construction method, aiming to solve the problems of difficulty in reinforcement and high cost when the anti-slide pile structure is abnormal.
[0004] The present invention is implemented by adopting the following technical scheme: a reinforced concrete diagonal bracing structure reinforced by anti-sliding piles, comprising a diagonal bracing structure main body and a diagonal bracing structure foundation. The diagonal bracing structure foundation adopts a concrete foundation, and the size can be appropriately adjusted according to the geological conditions in front of the piles. The two ends of the diagonal bracing structure main body are respectively connected to the diagonal bracing structure foundation and the anti-sliding piles. The diagonal bracing structure main body adopts a cast-in-place reinforced concrete structure, and its structural size can be specifically adjusted according to the size of the anti-sliding piles and the on-site investigation.
[0005] Furthermore, the main reinforcement of the diagonal bracing structure body is made of 25mm diameter HRB400 steel bars, and the stirrups are made of 14mm HRB400 steel bars with a spacing of 200mm, and horizontal stirrups are added within 800mm of the connection between the diagonal bracing structure body and the anti-slip piles and the diagonal bracing structure foundation.
[0006] Furthermore, both ends of the main body of the diagonal bracing structure are connected to the diagonal bracing structure foundation and the anti-sliding piles by chemical anchoring, and the main reinforcement extends into the anti-sliding piles and the diagonal bracing structure foundation by no less than 600 mm.
[0007] A construction method of a reinforced concrete diagonal brace structure reinforced with anti-slide piles comprises the following steps: Step 1: On-site investigation and design: Conduct a detailed geological survey of the landslide area, and design the location, quantity, depth of the anti-slide piles and the structural dimensions, inclination angle and arrangement of the reinforced concrete diagonal braces based on the survey results; Step 2: Construction preparation: clean up debris and loose soil on the surface of the landslide area, prepare construction materials, and build temporary construction facilities; Step 3: Anti-slide pile construction: dig holes for anti-slide piles, install steel cages, and pour concrete to form anti-slide piles; Step 4: Construction of diagonal brace foundation: excavate the diagonal brace foundation pit, lay the steel mesh, and pour concrete to form the diagonal brace structure foundation; Step 5: Fabrication and installation of steel frame: Fabricate the steel frame, including main bars, stirrups and tie bars, and install them in the predetermined position; Step 6: Formwork installation and concrete pouring: Make and install the formwork, pour concrete into the formwork, and vibrate to compact it; Step 7, maintenance and acceptance: Maintain the cast reinforced concrete diagonal bracing structure and conduct quality acceptance after the maintenance period.
[0008] Furthermore, in step three, after the concrete reaches the designed strength, the pile top is processed to ensure that the pile top is flat and sufficient steel anchors are reserved at the connection position with the diagonal brace.
[0009] Furthermore, in step five, ensure that the connection between the steel skeleton and the anti-sliding piles and the diagonal bracing structure foundation is firm and reliable to meet the design requirements.
[0010] Furthermore, in step six, after the concrete reaches initial setting, the formwork is removed and surface curing is performed.
[0011] The invention discloses a reinforced concrete diagonal bracing structure reinforced with anti-slide piles and a construction method, and its beneficial effects include: Setting a reinforced concrete diagonal brace near the ground elevation in front of the anti-slip pile can not only increase the rigidity and integrity of the support system, but also provide a certain anti-slip force, which can bring more safety guarantees.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] like Figure 1 As shown, a reinforced concrete diagonal bracing structure reinforced with anti-sliding piles includes a diagonal bracing structure body 2 and a diagonal bracing structure foundation 3. The diagonal bracing structure foundation 3 adopts a C30 plain concrete foundation with a size of 2194mm*1800mm*1000mm, which can be appropriately adjusted according to the geology (soil conditions) in front of the pile. The two ends of the diagonal bracing structure body 2 are respectively connected to the diagonal bracing structure foundation 3 and the anti-sliding pile 1. The diagonal bracing structure body 2 can increase the stiffness and integrity of the anti-sliding pile support system and provide a certain anti-sliding force.
[0017] The main body 2 of the diagonal bracing structure adopts a cast-in-place reinforced concrete structure. The structural dimensions can be adjusted according to the dimensions of the anti-sliding piles 1 and the on-site investigation. The main reinforcement of the main body 2 of the diagonal bracing structure adopts 25mm diameter HRB400 steel bars, and the stirrups adopt 14mm HRB400 steel bars with a spacing of 200mm. Horizontal stirrups 4 are added within 800mm of the connection between the main body 2 of the diagonal bracing structure and the anti-sliding piles 1 and the diagonal bracing structure foundation 3, and C30 concrete is used for pouring.
[0018] Both ends of the diagonal bracing structure body 2 are connected to the diagonal bracing structure foundation 3 and the anti-sliding pile 1 by chemically embedded reinforcement, and the main reinforcement extends into the anti-sliding pile 1 and the diagonal bracing structure foundation 3 by no less than 600 mm.
[0019] A construction method of a reinforced concrete diagonal brace structure reinforced with anti-slide piles comprises the following steps: Step 1: Site investigation and design: Conduct detailed geological surveys of the landslide area to understand the soil structure, groundwater conditions, landslide type and scale, etc. Based on the survey results, design the location, quantity, depth of anti-slide piles, and the structural dimensions, inclination angle and arrangement of reinforced concrete diagonal braces to ensure that the structure is stable and economically reasonable.
[0020] Step 2: Construction preparation: Clean up the debris and loose soil on the surface of the landslide area to ensure that the construction site is flat. Prepare the required steel bars, concrete materials, formwork, scaffolding and other construction materials, and check whether their quality meets the requirements. Build temporary construction facilities, such as mixing stations, steel bar processing sheds, etc.
[0021] Step 3: Anti-slip pile construction: According to the design drawings, use a drilling machine or excavator to dig the anti-slip pile holes. Install the steel cage in the hole, ensuring that the diameter, length and spacing of the steel cage meet the design requirements. Pour concrete into the hole and vibrate it to form an anti-slip pile. After the concrete reaches the design strength, perform pile top treatment to ensure that the pile top is flat and that sufficient steel anchors are reserved at the connection with the diagonal brace.
[0022] Step 4: Construction of diagonal bracing foundation: According to the design position of the diagonal brace, dig the diagonal brace foundation pit to ensure that the size and depth of the foundation pit meet the design requirements. Lay the steel mesh in the foundation pit and pour concrete to form the foundation of the diagonal brace. After the foundation concrete reaches the design strength, clean and level the surface.
[0023] Step 5: Fabrication and installation of steel frame: According to the design size and shape of the diagonal brace, make a steel skeleton, including main bars, stirrups and tension bars. Transport the steel skeleton to the construction site and install it to the predetermined position using scaffolding or lifting equipment. Ensure that the connection between the steel skeleton and the anti-slip piles and diagonal brace foundation is firm and reliable to meet the design requirements.
[0024] Step 6: Formwork installation and concrete pouring: According to the shape and size of the diagonal brace, make and install the formwork to ensure that the flatness and verticality of the formwork meet the requirements. Apply a release agent inside the formwork to prevent the concrete from sticking to the formwork. Pour concrete into the formwork and vibrate it to make it dense to ensure that there are no bubbles or gaps in the concrete. After the concrete reaches initial setting, remove the formwork and perform surface maintenance.
[0025] Step 7: Maintenance and acceptance: The cast reinforced concrete bracing structure is maintained to ensure that the concrete is fully hardened. During the maintenance period, the stability and integrity of the bracing structure are regularly checked, and any problems found are promptly dealt with. After the maintenance period, a quality inspection is carried out to check whether the size, shape, strength, etc. of the bracing structure meet the design requirements. Only after the inspection is qualified can the subsequent construction or commissioning be carried out.
[0026] The above embodiments describe the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
