DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] See attached Figure 1-Figure 5 A protective device for construction engineering, comprising a foundation 1 cast in a pit foundation, a building body 100 installed on the foundation 1, drainage prefabricated parts 2 located in the pit foundation are laid around the foundation 1, a water collecting tank 3 is installed between adjacent drainage prefabricated parts 2, mud storage prefabricated boxes 7 located underground are buried on both sides of the windward surface of the building body 100, a channel prefabricated part 8 is connected between the mud storage prefabricated box 7 and the drainage prefabricated parts 2, and tripods 5 connected to each other are installed on both sides of the windward surface of the building body 100; The tripod 5 is composed of a vertical rod 51, an oblique rod 52 and a horizontal rod 53 connected end to end. The water collecting box 3 includes a water collecting bucket 32. A pull rod 511 located in the water collecting bucket 32 ​​is fixed at the bottom of the vertical rod 51. A piston 512 located at the bottom of the water collecting bucket 32 ​​is fixed to the pull rod 511. A diversion pipe 513 is connected between the top of the water collecting bucket 32 ​​and the drainage prefabricated component 2. The end of the inclined rod 52 is inserted into the ground and fixed with a blocking seat 521 located in the mud storage prefabricated box 7.

[0017] When in use, firstly, a pit is excavated, and a foundation 1 is poured therein. The foundation 1 is made of concrete material, and the foundation 1 is used to install the building body 100, which improves the anti-slip ability and enhances the effect of resisting the impact of mud and rock flow; Then, the drainage prefabricated component 2, the mud storage prefabricated box 7 and the channel prefabricated component 8 are installed. All three are concrete prefabricated components with reinforcing ribs inside to ensure the stability of the structure. Finally, the installation position of the water collecting tank 3 is excavated, and then the water collecting tank 3 is installed. The water collecting tank 3 is used to store accumulated water. On rainy days, rainwater will enter the drainage prefabricated component 2. The drainage prefabricated component 2 forms an isolation zone to prevent rainwater from invading the building body 100; When a disaster such as a debris flow or a strong wind occurs, the debris flow will be blocked by the drainage prefabricated component 2 to prevent it from directly impacting the building body 100. The debris flow will enter the drainage prefabricated component 2 and finally flow into the mud storage prefabricated box 7 through the channel prefabricated component 8, thus ensuring the safety of the building body 100. After the installation of the building body 100 is completed, the tripod 5 is installed. The tripod 5 is installed at the four corners of the building body 100 respectively. The tripod 5 is composed of a vertical rod 51, an inclined rod 52 and a horizontal rod 53, which form a stable triangular structure. The tripod 5 is used to ensure the structural stability of the building body 100 when strong winds and mudslides occur, and to improve its wind and mudslide resistance. When the tripod 5 is installed, the soil is backfilled at the location to cover the prefabricated mud storage box 7 and the prefabricated channel part 8.

[0018] In the southwest of my country, strong winds and rains in summer are often accompanied by mudslides, so buildings are often faced with multiple challenges in terms of protection.

[0019] Specifically, in the above weather, it rains and strong winds first, and rainwater falls into the drainage prefabricated component 2 and is collected by the water collection box 3. The building body 100 can be supported by the tripod 5. When the wind is too strong, the tripod 5 may shake, and the shaking of the tripod 5 causes the vertical rod 51 to move along its installation direction. At this time, the vertical rod 51 will pull the pull rod 511 up, so that the piston 512 will rise. At this time, the water collection bucket 32 ​​is full of rainwater, and the resistance of the piston 512 to rise will be greatly increased, thereby improving the stability of the vertical rod 51 under the action of force; In addition, when the piston 512 is pulled, it will discharge the rainwater in the water collection barrel 32 into the drainage prefabricated member 2 through the diversion pipe 513, and then the rainwater will fall into the water collection barrel 32 again, so that the piston 512 is pressed again, thus forming a cyclic pressurized state, which further improves the stability of the vertical rod 51 and ensures the supporting strength of the tripod 5 to the building body 100; When rain and strong winds continue for a period of time, debris flow often breaks out, and the impact of debris flow is often more serious than strong winds. As mentioned above, the debris flow will enter the drainage prefabricated component 2, and then flow into the mud storage prefabricated box 7 through the channel prefabricated component 8. When a large amount of debris flow enters the mud storage prefabricated box 7, the debris flow will press the blocking seat 521 to prevent the inclined rod 52 from being dislocated due to the impact of wind and other forces, so that it can continue to ensure the triangular structure of the tripod 5, thereby providing support for the building body 100; And because the structural strength of the building body 100 in the prior art is often very high and has the effect of resisting the impact of mudslides, it is only necessary to ensure the stability of its installation. Therefore, through the above-mentioned setting, the stability of the building body 100 can be guaranteed under any circumstances, thereby playing a protective effect.

[0020] In addition, by setting up the foundation 1 and the drainage prefabricated parts 2, the building body 100 is effectively isolated from the surrounding environment, which can prevent snakes and rats from entering under the temporary housing by digging tunnels. In addition, it can be combined with snake and rat repellent drugs used in the prior art, as well as electronic devices such as ultrasonic snake and rat repellents, to comprehensively ensure that the building body 100 is prevented from intrusion by snakes and rats, thereby ensuring the safety of users.

[0021] In this embodiment, tripods 5 are installed at the four corners of the building body 100, the horizontal rod 53 is fixed between the vertical rod 51 and the diagonal rod 52, the vertical rod 51 and the diagonal rod 52 are both anchored in the ground, and a reinforcing plate 500 is fixed between each tripod 5, and the reinforcing plate 500 is located at the top of the building body 100.

[0022] like Figure 1 As shown, in this diagram, arrows are used to indicate the wind direction at the installation location of the building body 100. The tripods 5 at various locations are connected by reinforcing plates 500 so that the tripods 5 are integrated as a whole, which can improve the strength of the support. In addition, the vertical rods 51 and the diagonal rods 52 are both anchored in the ground to ensure stability under normal use.

[0023] like Figure 4 As shown, a scaffolding board 6 is laid on the top of the drainage prefabricated component 2, a V-shaped drainage groove 4 is opened at the bottom of the drainage prefabricated component 2, the middle part of the scaffolding board 6 is a split part 62, and a supporting frame 61 fixed in the drainage prefabricated component 2 is provided at the bottom of the scaffolding board 6.

[0024] By laying the scaffolding board 6, it can be ensured that the user can pass through the drainage prefabricated component 2 normally, and the scaffolding board 6 is provided with holes to ensure that rainwater can flow into the drainage prefabricated component 2 normally; By setting the support frame 61 and the splitting part 62, when a debris flow strikes, the support frame 61 will be directly broken at the splitting part 62 due to the heavy weight of the debris flow. At this time, the scaffolding board 6 will be broken at the splitting part 62, so that the scaffolding board 6 is divided into two halves, so that the drainage prefabricated component 2 can bear the debris flow, and the scaffolding board 6 will not cause any obstruction.

[0025] like Figure 1 and Figure 4 As shown, the water collecting box 3 also includes a water diversion channel 31, which is located above the water collecting barrel 32. A liquid level sensor 33 and a drainage pump 34 are provided on the side of the water collecting barrel 32. The drainage pump 34 is connected to an external discharge pipe 35. The V-shaped drainage groove 4 is connected to the water diversion channel 31, and a check valve 400 is provided at the connection point. A water retaining cover 300 is provided at the connection point between the drainage prefabricated component 2 and the channel prefabricated component 8.

[0026] On rainy days, rainwater will flow into the water channel 31 through the V-shaped drainage trough 4, and the water in the water channel 31 will be discharged into the water collecting barrel 32. As the rainwater increases, the water level in the water collecting barrel 32 rises rapidly. The water level in the water collecting barrel 32 can be detected by the liquid level sensor 33 to prevent the water collecting barrel 32 from being full. The water in the water collecting barrel 32 can be discharged by starting the drainage pump 34, and the water will be discharged to low-lying areas through the external drainage pipe 35, ensuring that rainwater can be collected continuously.

[0027] The setting of the check valve 400 can prevent the water in the water collecting barrel 32 from flowing back. The setting of the water retaining cover 300 ensures that when light rainwater enters, the water retaining cover 300 will not open, thereby preventing rainwater from entering the mud storage prefabricated box 7. It will only open when a heavy mudslide enters.

[0028] like Figure 5 As shown, in this embodiment, the foundation 1 includes a concrete layer 11 at the bottom, a crushed stone layer 12 is laid on the concrete layer 11, and drainage boards 13 fixed on both sides of the concrete layer 11 are provided on the crushed stone layer 12. A plurality of drainage channels 15 are provided in adjacent crushed stone layers 12, and the drainage channels 15 penetrate the concrete layer 11 and are connected to the drainage prefabricated parts 2. The foundation 1 is provided with a plurality of installation holes 14 penetrating the concrete layer 11, the crushed stone layer 12 and the drainage boards 13.

[0029] This can effectively prevent rainwater from intruding and improve the strength of the foundation 1. In addition, the installation hole 14 is opened so that the bottom of the building body 100 can be provided with connecting parts for adaptive installation, thereby improving the installation stability of the building body 100.

[0030] Specifically, in this embodiment, the concrete layer 11 is a 20 cm thick C30 concrete layer, with a reinforcement ratio of 0.5% and a compressive strength of ≥30 MPa, the crushed stone layer 12 is a 30 cm thick graded crushed stone layer, with a particle size of 10-30 mm and a permeability coefficient of ≥1×10⁻²cm / s, and the drainage board 13 is a 5 cm thick polymer drainage board with a convex point height of 10 mm and a drainage capacity of ≥3 L / m・s; In addition, the drainage prefabricated member 2 set around the foundation has an upper opening width of 60 cm and a depth of 40 cm; A 50cm deep concrete isolation zone is also set up around the foundation, which contains a 304 stainless steel mesh with a pore size of 0.5cm and is coated with a nano-snake repellent coating with a weather resistance of ≥5 years.

[0031] Therefore, the present invention integrates the functions of preventing snakes, rats and insects, wind and mudslides. The concrete isolation belt can prevent snakes and rats from digging holes and enhance the anti-slip ability of the foundation.

[0032] The present invention also discloses a protection method for construction engineering, comprising the following steps: S1: excavate the pit foundation, pour the foundation 1 in the center of the pit foundation, and after the foundation 1 is solidified, install the drainage prefabricated parts 2, the mud storage prefabricated box 7 and the water collection tank 3; S2: Install the channel prefabricated member 8 between the drainage prefabricated member 2 and the mud storage prefabricated box 7, and then install the building body 100 on the foundation 1. After the building body 100 is installed, install the tripod 5 so that the pull rod 511 enters the water collection bucket 32, and the inclined rod 52 is inserted into the mud storage prefabricated box 7; S3: After safety is completed, backfill the pit foundation with soil.
