[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] Reference Figures 1 to 5 As shown, the utility model is a basement enclosure reinforcement structure, the basement enclosure includes an underground continuous wall 1, the underground continuous wall 1 also serves as the basement exterior wall, and also includes a reinforcement column 2, the reinforcement column 2 is connected to the underground continuous wall 1, the inner side of the underground continuous wall 1 is connected to a reinforcement beam 3, and the reinforcement beam 3 is connected to the reinforcement column 2. The construction of the underground continuous wall 1 mentioned above includes first casting guide walls on both sides of the underground continuous wall 1, using a grab bucket grooving method to form a groove between the guide walls, placing a steel cage and then pouring concrete to form the underground continuous wall 1. The purpose of casting the guide wall mainly includes ensuring the accuracy of the grooving of the underground continuous wall 1 and preventing water and debris from falling into the groove. Figure 2 As shown, the depth of the underground continuous wall 1 is greater than the depth of the basement floor 5. The underground continuous wall 1 reserves steel bars for pouring with the floor slab 5, and the floor slab 5 and the underground continuous wall 1 are poured into a whole. Water-stopping structures are provided in the floor slab 5 and the underground continuous wall 1, such as waterproofing membranes, waterproofing membranes, water-stopping steel plates and other structures. Support columns 4 are connected to the underground continuous wall 1 at a predetermined interval. When pouring the underground continuous wall 1, steel bars are first reserved at the positions of the support columns 4. The arrangement method of the reserved steel bars includes reserving column longitudinal bars. The main bars of the underground continuous wall 1 pass through the reserved steel bar positions. The arrangement method of the reserved steel bars adopts the existing technology, and the reserved steel bar positions are filled with foam. When pouring the support column 4, the filled foam is removed, and the support column 4 and the underground continuous wall 1 are poured together. The support column 4 can be used Figure 3 Connect to the ground wall by Figure 4The supporting column 4 can be used as the support of the underground continuous wall 1 and also as the structural column of the basement. The supporting column 4 can also be arranged in another way. The underground continuous wall 1 has a gap between the supporting column 4 and the underground continuous wall 1 through the reserved beam reinforcement, and the supporting column 4 and the underground continuous wall 1 are connected by an integrally cast short beam. The supporting column 4 is connected to the main beams 6 of multiple basements at equal intervals in the longitudinal direction, and the floor slab 7 is cast above the main beams 6. The reserved reinforcement of the underground continuous wall 1 extends to the connection node of the main beam 6 and the supporting column 4 and is cast as a whole with the supporting column 4 and the main beam 6. The reinforcement connected to the floor slab 7 is reserved and cast as a whole with the floor slab 7. The other end of the main beam 6 is connected to the structural column of the basement (not shown), and the structural column is connected to the supporting column of the underground continuous wall 1 on the other side through other main beams 6. The main beam 6 and the supporting column 4 can withstand the inward horizontal force of the underground continuous wall 1, reducing the horizontal displacement and deformation of the underground continuous wall 1. A horizontal reinforcement beam 3 is arranged between adjacent support columns 4, and both ends of the reinforcement beam 3 are connected to the corresponding support columns 4 respectively. A longitudinal reinforcement column 2 is arranged on the reinforcement beam 3, and the reinforcement column 2 is arranged between the support columns 4 to form a cross structure with the reinforcement beam 3 to strengthen the structural strength of the underground continuous wall 1. The reinforcement beam 3, the reinforcement column 2, the support column 4, and the basement main beam 6 form a three-dimensional support structure. It also includes a basement lining wall 9, refer to Figure 6 As shown, the outer surface of the lining wall 9 is provided with a predetermined spacing from the reinforcement column 2 and the reinforcement beam 3. Although the structure of the basement enclosure is strengthened in this embodiment, the underground continuous wall 1 may still have certain deformation and leakage, which directly affects the normal use of the basement, and the decorative layer of the basement inner wall is easily affected by deformation, cracking and water seepage. In this embodiment, the lining wall 9 and the underground continuous wall 1 are integrated as a whole, the underground continuous wall 1 serves as the outer wall, and the lining wall 9 is the inner wall for easy decoration and decoration. The lining wall 9 is simple to construct and easy to save costs. The structure of the reinforcement beam 3, the reinforcement column 2, the support column 4 and the main beam 6 strengthens the structural strength of the underground continuous wall 1, so that there is no need to construct a shear wall as the outer wall of the basement, saving construction time, materials and costs. By setting a gap between the lining wall and the underground continuous wall, even if the underground continuous wall 1 undergoes certain deformation and leakage, it will not directly affect the decorative layer of the lining wall 9. Preferably, a drainage ditch 10 is provided between the underground continuous wall 1 and the lining wall 9. The drainage ditch 10 is connected to the collection well and is connected to the drainage system of the basement through a pipe and finally discharged to the outside. The underground continuous wall 1 is generally provided with a water-stopping structure such as a waterproof membrane, a water-stopping plate and other structures. This embodiment can ensure that the lining wall 9 will not be directly affected by the leakage when the underground continuous wall 1 leaks.

[0022] In the above embodiment, referring to Figure 1 As shown, the reinforcing column 2 is arranged between the supporting columns 4 and is parallel to the supporting columns 4. In the above embodiment, part of the reinforcing beam 3 is connected to the supporting columns 4, and part of the reinforcing beam 3 is connected to the connecting node between the main beam 6 and the supporting columns 4.

[0023] In the above embodiment, referring to Figure 5 As shown, it also includes a prestressed anchor cable 8, one end of which is set in the soil layer or rock layer outside the underground continuous wall 1, and the other end is fixed on the reinforcement beam 3. In this embodiment, holes can be reserved in the underground continuous wall 1, and the reserved holes are filled with foam. Before the construction of the basement reinforcement beam 3, the holes are cleaned and the anchor cable 8 is constructed. When the reinforcement beam 3 is poured with concrete, the reserved holes are filled and one end of the anchor cable 8 is connected to the reinforcement beam 3. Of course, it can also be carried out by subsequent hole forming and fixing. The anchor cable 8 can provide a certain pulling force to improve the deformation resistance of the reinforcement beam 3.
