[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0043] Such as Figure 1 And Figure 2 And Figure 3 And Figure 4 And Figure 5As shown in the figure, the enhanced anchor rod reaction frame includes a main reaction frame 1, a secondary reaction frame 2, a connecting component, and several anchor rods 3. The above-mentioned connecting component can be sleeved and connected to the corresponding pile body. The lower part of the connecting component is used to connect to the ground, and the upper part of the connecting component is used to bear pressure. The above-mentioned main reaction frame 1 and secondary reaction frame 2 are both horizontally arranged, and the middle parts of the main reaction frame 1 and the secondary reaction frame 2 are hinged at the connecting component. Several vertically arranged anchor rods 3 are connected to both the main reaction frame 1 and the secondary reaction frame 2.

[0044] The enhanced anchor rod reaction frame can provide stable support and bear the corresponding reaction force. It is widely used in the fields of geotechnical engineering, underground engineering, slope stability, etc.

[0045] Specifically, since the middle parts of both the main reaction frame 1 and the secondary reaction frame 2 are hinged at the connecting component, once the connecting component is connected to the corresponding pile body, the main reaction frame 1 and the secondary reaction frame 2 can swing adaptively according to the needs of the actual occasion, and finally ensure that the entire reaction frame can be stably connected to the corresponding occasion.

[0046] The main reaction frame 1 and the secondary reaction frame 2 can swing adaptively. Therefore, this reaction frame can also be applied in narrow occasions.

[0047] Since several anchor rods are connected to both the main reaction frame and the secondary reaction frame, when the position between the secondary reaction frame and the main reaction frame changes, the positions of the corresponding anchor rods can be changed, so that the anchor rods are connected to the corresponding required positions, and finally a good reinforcement effect is achieved on the application occasion.

[0048] The main reaction frame 1 is in the shape of a long plate, and the secondary reaction frame 2 has a horizontally penetrating connection cavity along its width direction. The above-mentioned secondary reaction frame 2 is located at the connection cavity.

[0049] Such a structure can enable the secondary reaction frame 2 to swing stably relative to the main reaction frame 1.

[0050] The main reaction frame 1 includes a connecting cylinder 1a and a rod section 1b. The number of rod sections 1b is two, and the inner ends of the two rod sections 1b are respectively fixedly connected to the front and rear sides of the connecting cylinder 1a.

[0051] The width dimension of the rod section 1b is smaller than the outer diameter dimension of the connecting cylinder 1a. One of the rod sections 1b is flush with the left side of the connecting cylinder 1a, and the other rod section 1b is flush with the right side of the connecting cylinder 1a. The two rod sections 1b are arranged in parallel.

[0052] The above-mentioned connecting cylinder 1a and the rod sections 1a located on its front and rear sides form a unit body. The number of unit bodies is two, and the two unit bodies are arranged adjacent to each other up and down. Among the two rod sections 1b that are vertically aligned in the two unit bodies, the outer ends of the two rod sections 1b are fixedly connected. The above-mentioned secondary reaction frame 2 is located between the two unit bodies.

[0053] The secondary reaction frame 2 includes a connecting cylinder two 2a and a rod section two 2b. The number of the rod sections two 2b is two. The inner ends of the two rod sections two 2b are respectively fixedly connected to the front and rear sides of the connecting cylinder two 2a.

[0054] The width dimension of the rod section two 2b is smaller than the outer diameter dimension of the connecting cylinder two 2a. The outer side of one of the rod sections two 2b is flush with the left side of the connecting cylinder two 2a, and the outer side of the other rod section two 2b is flush with the right side of the connecting cylinder two 2a. The two rod sections two 2b are arranged in parallel.

[0055] Such a structure can not only enable the main reaction frame 1 and the secondary reaction frame 2 to be stably hinged, but also enable the secondary reaction frame 2 and the main reaction frame 1 to be stably fitted together. After the two are fitted together, it can effectively reduce the excessive space occupied by the reaction frame. That is to say, the rod section one 1b and the rod section two 2b can be stably fitted together.

[0056] The connecting component includes a cylindrical body 4. The lower end of the body 4 has a flat base 4a. The above-mentioned connecting cylinder one 1a and connecting cylinder two 2a are both sleeved on the body 4.

[0057] The body 4 can be stably sleeved on the corresponding positioning shaft or pile body. The contact area between the base 4a and the ground can effectively improve the connection stability between the connecting component and the ground.

[0058] The body 4 and the base 4a are of an integral structure.

[0059] The base 4a is rectangular. The body 4 is located at the center of the base 4a. Fasteners are provided at the corners of the base 4a.

[0060] There are several fasteners on the base 4a. The base 4a can be stably connected to the ground through the multiple fasteners.

[0061] The upper part of the body 4 has a flat bearing tray 4b. The bearing tray 4b is rectangular. Vertical support rods 4b1 are provided at the corners of the bearing tray 4b.

[0062] The number of the support rods 4b1 is several and the length dimensions of all the support rods 4b1 are the same. The operation site can be more stably connected through the support rods 4b1.

[0063] An auxiliary anchor rod assembly is further included. The number of the auxiliary anchor rod assemblies is two and the two auxiliary anchor rod assemblies are arranged in one-to-one correspondence with the two rod sections two 2b.

[0064] The auxiliary anchor rod assembly includes a U-shaped clip 5. The U-shaped notch of the clip 5 is located at its side. The U-shaped port of the clip 5 is hinged on the rod section two 2b. A plurality of vertically arranged anchor rods 3, the upper ends of which are connected to the clip 5.

[0065] Since there are also multiple anchor rods 3 on the auxiliary anchor rod assembly, the operation stability can be further improved through the auxiliary anchor rod assembly.

[0066] Meanwhile, since the collet 5 in the auxiliary anchor rod assembly has its U-shaped open end hinged at the secondary reaction frame 2, the collet 5 with the anchor rod 3 thereon can swing adaptively, so that the entire reaction frame can better adapt to the operation environment.

[0068] P1. First, conduct a survey of the construction site and locate the position of the engineering pile;

[0069] P2. According to the actual undulation of the site, transport the enhanced anchor rod reaction frame to the positioning point of the engineering pile, and fix the base to the pile position point through the anchor bolts;

[0070] P3. Adjust the main reaction frame and the secondary reaction frame. By adjusting the main reaction frame and the secondary reaction frame, make at least three points of the reaction frame contact the ground and adjust it to a horizontal state. Insert the anchor rod into the ground and fix the main reaction frame and the secondary reaction frame to the ground;

[0071] P4. Adjust the auxiliary anchor rod assembly. According to the ground conditions of the site, unfold the auxiliary anchor rod assembly, and strengthen and fix the anchor rods on the auxiliary anchor rod assembly to the ground;

[0072] P5. Install the pressing equipment on the bearing tray, fix it well, and detect data such as verticality;

[0073] P6. Check the connections of all bolts to ensure they are tightened and there is no looseness;

[0077] Moreover, after being stored, it occupies a small space, is applicable to relatively narrow construction spaces, and is especially applicable to the environmental conditions of the reinforcement projects of existing buildings.

[0078] In addition, this device is provided with multiple defense lines, which play a crucial role in construction safety; the materials are convenient to obtain, suitable for mass production, put into construction use, and can create great economic and social benefits.
