Correspondingly, the inner cavity of the bottom plate part is connected with the space below the bottom plate and the concrete pad through the gap of the second block, so that the inner cavity of the bottom plate part can balance the air pressure inside the basement to some extent, so that the underground water in the foundation soil is not easy to penetrate into the bottom plate of the basement from below.

[0009] By adopting the technical scheme, the concrete frame closes the two opposite sides of the holes of the second blocks corresponding to the bottom plate part, and closes the bottom of the outer wall part, and the upper cover closes the top of the outer wall part. The concrete frame can limit the position of the bottom plate part, and under the constraint of the concrete frame, the second blocks can be kept in abutting state, so as to reduce the gap between the second blocks, thereby facilitating the closure of the holes of the second blocks.

[0017] By using the above technical scheme, the floor part of the block partition needs to bear the weight of the main structure of the basement, so that the floor part is more prone to move downward relative to the concrete frame; since the inner side surfaces of the concrete frame gradually incline towards the center of the concrete frame from top to bottom, when the floor part tends to move downward, the floor part exerts an extrusion force outward on the concrete frame through the mortar joint layer, and correspondingly, the concrete frame exerts a counter force on the floor part in the direction of the center of the concrete frame, thereby facilitating the mutual compression of the second blocks to reduce the separation of adjacent second blocks to form gaps, and facilitating the second blocks to maintain a closed state.

DETAILED DESCRIPTION

[0037] The following description will be made in conjunction with the accompanying drawings. Figures 1-6 The application is further described in detail.

[0038] The embodiments of the application disclose a basement waterproof structure. Referring to Figure 1 , the basement waterproof structure comprises a wall 1, a base plate 2, a concrete cushion 3 and a block partition 5, the wall 1 and the base plate 2 form a main structure of the basement, the concrete cushion 3 is located below the base plate 2, and the outer surfaces of the wall 1 and the base plate 2 are each provided with a waterproof layer 4, the waterproof layer 4 is made of asphalt waterproof coiled material, and the waterproof layer 4 on the outer surface of the base plate 2 is laid on the upper surface of the concrete cushion.

[0039] Referring to Figure 1 , Figure 2 and Figure 3 , the outer layer of the block comprises an outer wall part 51 and a base plate part 52, the outer wall part 51 surrounds the wall 1, and the base plate part 52 is located below the concrete cushion; the outer layer of the block is formed by being built by means of the hollow block 501, and the jointing material for connecting adjacent hollow blocks 501 is asphalt concrete; the hollow block 501 has a hole 5011, two ends of the hole 5011 are provided in a penetrating manner, and the hollow block 501 is provided with a notch 5012 communicating with the hole 5011. The hollow block 501 corresponding to the outer wall part 51 is defined as a first block, the hollow block 501 corresponding to the base plate part 52 is defined as a second block, the hole 5011 of the first block is arranged in a vertical direction, the holes 5011 of the first blocks collectively serve as an inner cavity of the outer wall part 51, the notch 5012 of the first block faces the wall 1, the hole 5011 of the second block is arranged in a horizontal direction, the holes 5011 of the second blocks collectively serve as an inner cavity of the base plate part 52, and the notch 5012 of the second block faces the base plate 2.

[0040] Referring to Figure 1 and Figure 2The outer wall part 51 comprises a block wall 511 and a concrete column 512 corresponding to the corner part of the outer wall part 51. The block wall 511 is formed by first blocks, and the holes 5011 of the upper and lower adjacent first blocks are in communication with each other. The gap or joint between the block wall 511 and the concrete column 512 is filled with asphalt concrete.

[0041] With reference to Figure 1 and Figure 3 The bottom plate part 52 comprises a plurality of block partitions 521 and support purlins 522. The support purlins 522 are used for supporting the concrete cushion 3. The block partitions 521 are formed by second blocks, and the adjacent two second blocks are aligned with each other along the direction of the holes 5011 of the second blocks. The support purlins 522 are concrete structures, and are connected with the concrete frame 53 as a whole. The support purlins 522 are parallel to each other and are arranged along the direction of the holes 5011 of the second blocks. Each support purlin 522 is located between the adjacent two block partitions 521.

[0042] With reference to Figure 1 The concrete frame 53 is arranged between the lower side of the outer wall part 51 and the peripheral side of the bottom plate part 52, and seals the inner cavity of the bottom plate part 52. The top of the outer wall part 51 is provided with an upper cover 54, and the concrete frame 53 and the upper cover 54 jointly seal the inner cavity of the outer wall part 51.

[0043] The holes 5011 of the first blocks close to the foundation soil are difficult to communicate with the outside, and the holes 5011 of the second blocks close to the foundation soil are also difficult to communicate with the outside. The holes 5011 of the first blocks close to the basement wall 1 are in communication with the space outside the wall 1 through the notches 5012, so that the air pressure in the holes 5011 of the first blocks can form a certain balance with the air pressure inside the basement, thereby preventing the underground water in the foundation soil from penetrating into the wall 1 of the basement. Correspondingly, the holes 5011 of the second blocks close to the basement bottom plate 2 are in communication with the space outside the bottom plate 2 through the notches 5012, so that the air pressure in the holes 5011 of the first blocks can form a certain balance with the air pressure inside the basement, thereby preventing the underground water in the foundation soil from penetrating into the bottom plate 2 of the basement.

[0044] With reference to Figure 1The lower surface of the upper cover 54 is provided with a groove 541, the groove 541 has a downward opening, the groove 541 has an annular structure, and the groove 541 extends along the circumference of the outer wall. The upper cover 54 is provided with an air inlet pipe joint 55, and the air inlet pipe joint 55 is provided with an on-off valve 551. The upper cover 54 is provided with an air outlet pipe joint 56, and the air outlet pipe joint 56 is detachably connected with a pipe cap 561. The connection between the pipe cap 561 and the air outlet pipe joint 56 is a threaded connection. The air inlet pipe joint 55 and the air outlet pipe joint 56 are located on opposite sides of the wall body 1.

[0045] An annular passage is formed between the groove 541 of the upper cover 54 and the top surface of the outer wall part 51. When air is introduced into the inner cavity of the outer wall part 51 through the air inlet pipe joint 55, the air can enter the inner cavity of the outer wall part 51 through the groove 541, thereby increasing the air pressure inside the outer wall part 51 and making it more difficult for groundwater to seep into the inner cavity of the outer wall part 51. On the other hand, when the air enters the inner cavity of the outer wall part 51, the pipe cap 561 is removed, and the air inside the outer wall part 51 can be discharged from the outer wall part 51. The process of discharging air from the outer wall part 51 can carry out the moisture inside the outer wall part 51, which is beneficial to reduce the moisture in the inner cavity of the outer wall part 51.

[0046] Referring to Figure 1 and Figure 2 , the outer wall part 51 is inserted with a drainage pipe 6, the drainage pipe 6 includes a vertical pipe section 61, a horizontal pipe section 62, and a water outlet pipe section 63. The two ends of the horizontal pipe section 62 are connected to the upper end of the vertical pipe section 61 and the upper end of the water outlet pipe section 63, respectively. The lower end of the water outlet pipe section 63 extends to a space such as a sewage pool or a drainage ditch, and the lower end of the water outlet pipe section 63 is lower than the lower end of the vertical pipe section 61. The vertical pipe section 61 is inserted into the inner cavity of the outer wall part 51, the lower end of the vertical pipe section 61 extends to the concrete frame 53, and the upper end of the vertical pipe section 61 penetrates the upper cover 54. The water outlet pipe section 63 is provided with a water inlet bypass pipe 64, and the water inlet bypass pipe 64 is provided with a lock valve 65, which can be a ball valve, a stop valve, etc.

[0047] When a large amount of groundwater seeps into the inner cavity of the outer wall part 51, tap water can be injected into the water outlet pipe section 63 of the drainage pipe 6 through the water inlet bypass pipe 64. During the process of water flowing downward in the water outlet pipe section 63, the drainage pipe 6 can form a negative pressure, so that the drainage pipe 6 can continuously discharge the water in the inner cavity of the outer wall part 51 through the siphon effect.

[0048] Referring to Figure 1 , the concrete frame 53 is embedded with a plurality of bends 531. One end of the bend 531 communicates with the hole 5011 of the first block, and the other end of the bend 531 communicates with the hole 5011 of the second block. Therefore, the air flow entering the inner cavity of the outer wall part 51 can also enter the inner cavity of the floor part 52, so as to increase the air pressure in the inner cavity of the floor part 52, thereby reducing the seepage of groundwater into the inner cavity of the floor part 52.

[0049] In addition, under the condition that the elbow 531 communicates with the hole 5011 of the second block, the underground water seeping into the inner cavity of the floor part 52 can be sucked by the vertical pipe section 61 of the drain pipe 6 inserted into one of the elbows 531.

[0050] With reference to Figure 1 and Figure 4 , the inner side surface of the concrete frame 53 is gradually inclined toward the center of the concrete frame 53 from top to bottom, and a mortar joint layer 57 is arranged between the inner side surface of the concrete frame 53 and the peripheral surface of the floor 2. When the floor part 52 is subjected to the gravity of the basement main structure, the floor part 52 tends to move downward, and the floor part 52 exerts an outward extrusion force on the concrete frame 53 through the mortar joint layer 57. Correspondingly, the concrete frame 53 exerts a counter force on the floor part 52 in the direction of the center of the concrete frame 53, so that the second blocks are pressed against each other, the adjacent second blocks are not easy to separate from each other to form a gap, and the hole 5011 of the second block is kept in a closed state.

[0051] With reference to Figure 1 and Figure 5 , in order to improve the load bearing performance of the second block, the cross section of the hole 5011 of the hollow block 501 is designed as an isosceles triangle in this embodiment, wherein the top angle of the hole 5011 of the second block is arranged upward, and the triangular structure has high stability, so that the second block is not easy to be damaged under the gravity of the basement main structure.

[0052] With reference to Figure 1 Figure 1 , the floor part 52 is arranged below the reinforcement mesh 7, the reinforcement mesh 7 supports the floor part 52, the reinforcement mesh 7 is welded and fixed with a plurality of vertical reinforcements 71, one end of the vertical reinforcement 71 penetrates the asphalt concrete 8 of the floor part 52, the top of the vertical reinforcement 71 is bent to form a hook portion 711, and the hook portion 711 is embedded in the concrete cushion layer 3 to connect and strengthen the vertical reinforcement 71 and the concrete cushion layer 3.

[0053] The floor part 52 of the block layer 5 is arranged on the reinforcement mesh 7, and the vertical reinforcement 71 connecting the reinforcement mesh 7 is embedded in the concrete cushion layer 3, so that the relative position between the reinforcement mesh 7 and the concrete cushion layer 3 is kept stable, thereby facilitating the floor part 52 of the block layer 5 to be subjected to the combined constraint of the reinforcement mesh 7 and the concrete cushion layer 3, and further keeping the structure of the floor part 52 of the block layer 5 stable.

[0054] The implementation principle of the basement waterproof structure of the embodiment of the present application is that the wall body 1 and the bottom plate 2 jointly form the main structure of the basement, and the block layer 5 separates the main structure of the basement and the foundation soil outside the basement. The outer wall part 51 of the block layer 5 corresponds to the wall body 1 of the basement, and the bottom plate part 52 of the block layer 5 corresponds to the bottom plate 2 of the basement. The hole 5011 of each first block corresponding to the outer wall part 51 jointly serves as the inner cavity of the outer wall part 51, and the hole 5011 of each second block corresponding to the bottom plate part 52 jointly serves as the inner cavity of the bottom plate part 52; when the underground water in the foundation soil flows to the main structure of the basement, the block layer 5 hinders the flow, so that the waterproof layer 4 outside the wall body 1 and the bottom plate 2 is protected, and the inner cavities of the outer wall part 51 and the bottom plate part 52 can balance the air pressure inside the basement, so that the underground water in the foundation soil is not easy to penetrate into the wall body 1 of the basement.

[0055] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
