Description

Technical Field

[0001] This invention relates to the field of composite foundation production equipment technology, specifically to a composite foundation that improves the bearing capacity of building foundation soil. Background Technology

[0002] Building foundations are divided into natural foundations and artificial foundations. A natural foundation is a foundation that can directly bear the load of a building without any treatment; conversely, an artificial foundation requires treatment using foundation treatment techniques. However, most current foundations are constructed using fully reinforced concrete structures, lacking seismic resistance. Currently, most seismic damping structures are complex in structure and consume a lot of materials, significantly increasing their cost.

[0003] In current urban planning, residential areas are often located near major traffic arteries. The increase in traffic volume and the transportation process of large trucks will generate significant vibrations. When smaller buildings are buried deep in the ground, there are certain gaps between the foundation and the soil. The vibrations from traffic will continuously widen these gaps and disrupt the load-bearing balance of the foundation. Currently, the market is dominated by deep-buried foundations, but the construction process for such foundations is complicated and the construction cost is relatively high. Summary of the Invention

[0004] The purpose of this invention is to provide a composite foundation that improves the bearing capacity of building foundation soil, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite foundation for improving the bearing capacity of building foundation soil, comprising an integral external structure, wherein the integral external structure further comprises an integral outer plate, and a plurality of condensation plates are fixedly connected to the outer wall of the integral outer plate. The purpose of setting the condensation plates is to use the temperature difference to cause water droplets to condense on the integral outer plate, which mix with the external soil through water inlet holes to fill the internal voids. An integral bottom plate is fixedly connected to the bottom outer wall of the integral outer plate, and further comprising:

[0006] A deep fixing mechanism includes a deep main rod, with several deep outer grooves on the outer wall of the deep main rod and a soil entry chute on the bottom outer wall of the deep main rod. The purpose of the soil entry chute is to effectively break through the soil surface and penetrate deep underground during the installation of the equipment, and to collect and compress the broken soil inward for use in subsequent fixing procedures. A deep soil entry hole is provided on the bottom outer wall of the soil entry chute.

[0007] A shallow fixing mechanism includes a shallow main rod, with several shallow outer grooves and several shallow water inlets on the outer wall of the main rod. The purpose of these shallow water inlets is to allow water droplets to condense on the condensate plate or rainwater to be collected by the top integrated water collection trough, so that the water enters the ground through the crushing teeth. The water source is transferred through the soil and passes through the shallow water inlets, allowing the internal soil and rainwater to mix thoroughly, fully adhere to the foundation, and repair gaps caused by various daily factors.

[0008] Preferably, the overall external mechanism further includes fixing holes formed on the overall base plate. The fixing holes are rotatably fixed with deep fixing mechanisms and shallow fixing mechanisms. When the foundation is deep into the soil, the fixing holes act as fulcrums of levers, providing inward fixing force for the top fixing bracket. The outer base plate is fixedly connected to the outer wall of the overall outer plate. An overall water collection trough is formed on the top outer wall of the outer base plate, which collects water when condensation forms on the condensation plate or when it rains outside, providing a mixed water source for the underground foundation.

[0009] Preferably, the overall external mechanism also includes a water inlet hole opened on the overall water collection tank, and a number of crushing teeth are fixedly connected to the bottom outer wall of the outer base plate. The purpose of setting the crushing teeth is to break the waterproof layer on the surface of the soil after installation, and to provide a water flow channel for the water flowing in from the water inlet hole. After the mud at the bottom dries, the crushing teeth also have a fixing effect. When the equipment is vibrated, the crushing teeth also break the outer wall of the soil, allowing water to enter the interior to repair the gaps.

[0010] Preferably, the deep fixing mechanism further includes deep holes formed on the side wall of the deep main rod. The deep holes not only provide installation positions for fixing the outer frame, but also increase the friction of the outer wall of the equipment. During the mud mixing stage, mud and sand can bury the deep holes inside. After drying, they can effectively prevent vertical vibration. Several fixing brackets are fixedly connected to the upper inner wall of the deep main rod.

[0011] Preferably, the deep fixing mechanism further includes a deep outer plate fixed to the outer wall of the deep main rod. A fixed outer frame is fixedly connected to the top outer wall of the deep outer plate. A fixed inner frame is rotatably connected to the fixed outer frame at the end away from the deep outer plate. The deep outer plate shrinks inward during the deep burial process and extends outward after being vibrated by various daily factors, increasing the resistance of the foundation and increasing the overall contact area of ​​the equipment.

[0012] Preferably, the deep fixing mechanism further includes an outer telescopic body fixed to the outer wall of the deep hole. A middle telescopic body is slidably connected to the central axis of the outer wall of the outer telescopic body, and an inner telescopic body is slidably connected to the central axis of the outer wall of the middle telescopic body. When the device is inserted into the soil, the deep hole is filled with soil. The middle and inner telescopic bodies expand outward due to the pressure of the soil, while the outer plate contracts inward during the deep burial process. After vibration caused by various daily factors, it extends outward to increase the resistance of the foundation.

[0013] Preferably, the shallow fixing mechanism further includes shallow holes formed on the outer wall of the shallow main rod. A soil-cutting groove is formed on the bottom outer wall of the shallow main rod, and a shallow soil-entry hole is formed on the bottom outer wall of the soil-cutting groove. A shallow fixing body is fixedly connected to the upper part of the inner wall of the shallow main rod. When the foundation of the present invention is fixed, the shallow fixing mechanism extends outward due to the resistance of the soil, and the top shallow fixing body grips the foundation more firmly to ensure the stability of the foundation. Moreover, the shallow fixing body is close to the soil surface. When the weather rains, the soil absorbs water and becomes soft, filling the gap between the soil and the shallow main rod caused by vibration. This can effectively prevent the gap between the foundation body and the soil surface from widening during vibration.

[0014] Preferably, the shallow fixing mechanism further includes a shallow outer plate fixed to the outer wall of the shallow main rod. A shallow blocking frame is fixedly connected to the top outer wall of the shallow outer plate, and a shallow outer body is fixedly connected to the outer wall of the shallow hole. A soil-covering inner groove is opened on the inner wall of the shallow outer body. With the soil-covering inner groove inside the invention, when the foundation is deeply buried and the mud cools, the soil-covering inner groove can increase the contact area of ​​the device and ensure the stability of the foundation. A condensation plate is fixedly connected to the outer wall of the device. The temperature difference causes water droplets to condense on the entire outer plate, which mix with the external soil through the water inlet hole to fill the internal gaps.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The present invention is designed with two fixing mechanisms, one deep and one shallow. The soil from the surface to 40 cm underground is dry, fine and has poor earthquake resistance. The soil below 40 cm is moist, soft and has poor fixation. According to the normal construction process of small villas, the foundation should be buried to 100 cm deep. After the foundation of the present invention is fixed, the shallow fixing mechanism extends outward due to the resistance of the soil, and the top shallow fixing body grips the foundation more firmly to ensure the stability of the foundation. The shallow fixing body is close to the soil surface. When the weather rains, the soil absorbs water and becomes soft, filling the gap between the soil and the shallow main rod caused by vibration. This can effectively prevent the gap between the foundation body and the soil surface from becoming larger during vibration.

[0017] (2) The present invention is provided with a soil-covered inner groove. When the foundation is buried deep and the mud cools down, the soil-covered inner groove can increase the contact area of ​​the equipment and ensure the stability of the foundation. The outer wall of the equipment is fixedly connected with a condensation plate. The temperature difference causes water droplets to condense on the entire outer plate. The water droplets mix with the external soil through the water inlet hole to fill the internal gaps.

[0018] (3) When the device is inserted into the soil, the deep soil entry hole is filled with soil. The inner middle layer expansion body and the inner layer expansion body are squeezed outward by the soil, and the deep outer plate shrinks inward during the deep burial process. After being vibrated by various daily factors, it extends outward to increase the resistance of the foundation. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figure 1 - Figure 3 This invention provides a technical solution: a composite foundation for improving the bearing capacity of building foundation soil, comprising an integral external structure 1, the integral external structure 1 further comprising an integral outer plate 101, a plurality of condensation plates 102 fixedly connected to the outer wall of the integral outer plate 101, the purpose of setting the condensation plates 102 is to use the temperature difference to condense water droplets on the integral outer plate 101, which mix with the external soil through water inlet holes 107 to fill the internal gaps, an integral bottom plate 103 fixedly connected to the bottom outer wall of the integral outer plate 101, and further comprising:

[0031] The deep fixing mechanism 2 includes a deep main rod 201. Several deep outer grooves 202 are opened on the outer wall of the deep main rod 201. An entry groove 203 is opened on the bottom outer wall of the deep main rod 201. The purpose of the entry groove 203 is to effectively break the soil surface and penetrate deep into the ground when the equipment is installed, and to collect and squeeze the broken soil inward for use in the subsequent fixing process. A deep entry hole 204 is opened on the bottom outer wall of the entry groove 203.

[0032] The shallow fixing mechanism 3 includes a shallow main rod 301, several shallow outer grooves 302 and several shallow water inlet holes 303 on the outer wall of the shallow main rod 301. The purpose of setting the shallow water inlet holes 303 is that when the condensation plate 102 condenses water droplets or the top integral water collection trough 106 collects rainwater, it enters the ground through the crushing tooth 108. The water source is transmitted through the soil and passes through the shallow water inlet holes 303, so that the soil inside is fully mixed with the rainwater, fully adheres to the foundation body and repairs gaps caused by various daily reasons.

[0033] The overall external mechanism 1 also includes a fixing hole 104 opened on the overall base plate 103. The fixing hole 104 is rotatably fixed with a deep fixing mechanism 2 and a shallow fixing mechanism 3. When the foundation is deep into the soil, the fixing hole 104 acts as a fulcrum of the lever, providing an inward fixing force for the top fixing bracket 206. The outer wall of the overall outer plate 101 is fixedly connected to the outer base plate 105. An overall water collection trough 106 is opened on the top outer wall of the outer base plate 105. When water droplets condense on the condensation plate 102 or when it rains outside, it plays the role of collecting water sources and providing mixed water sources for the underground foundation.

[0034] The overall external structure 1 also includes a water inlet hole 107 opened on the overall water collection tank 106. Several crushing teeth 108 are fixedly connected to the bottom outer wall of the outer base plate 105. The purpose of setting the crushing teeth 108 is to break the waterproof layer of the soil surface after installation and to provide a water flow channel for the water flowing in from the water inlet hole 107. After the mud at the bottom dries, the crushing teeth 108 also have a fixing effect. When the equipment is vibrated, the crushing teeth 108 also break the outer wall of the soil, allowing water to enter the interior to repair the gaps.

[0035] Example 2

[0036] Distinguishing features from Example 1;

[0037] like Figure 1 - Figure 8 As shown, the deep fixing mechanism 2 also includes deep holes 205 opened on the side wall of the deep main rod 201. The deep holes 205 not only provide an installation position for fixing the outer frame 208, but also increase the friction of the outer wall of the equipment. During the mud mixing stage, mud and sand can bury the deep holes 205. After drying, it can effectively prevent vertical vibration. Several fixed supports 206 are fixedly connected to the upper inner wall of the deep main rod 201.

[0038] The deep fixing mechanism 2 also includes a deep outer plate 207 fixed to the outer wall of the deep main rod 201. A fixed outer frame 208 is fixedly connected to the top outer wall of the deep outer plate 207. A fixed inner frame 209 is rotatably connected to the end of the fixed outer frame 208 away from the deep outer plate 207. The deep outer plate 207 shrinks inward during the deep burial process and extends outward after being vibrated by various daily factors, increasing the resistance of the foundation and increasing the overall contact area of ​​the equipment.

[0039] The deep fixing mechanism 2 also includes an outer telescopic body 210 fixed to the outer wall of the deep hole 205. A middle telescopic body 211 is slidably connected to the central axis of the outer wall of the outer telescopic body 210, and an inner telescopic body 212 is slidably connected to the central axis of the outer wall of the middle telescopic body 211. When the device is inserted into the soil, the deep hole 204 is filled with soil. The middle telescopic body 211 and the inner telescopic body 212 expand outward due to the pressure of the soil, and the deep outer plate 207 contracts inward during the deep burial process. After being vibrated by various daily factors, it extends outward to increase the resistance of the foundation.

[0040] The shallow fixing mechanism 3 also includes shallow holes 304 opened on the outer wall of the shallow main rod 301, a soil-cutting groove 305 opened on the bottom outer wall of the shallow main rod 301, a shallow soil-entry hole 306 opened on the bottom outer wall of the soil-cutting groove 305, and a shallow fixing body 307 fixedly connected to the upper inner wall of the shallow main rod 301. When the foundation of the present invention is fixed, the shallow fixing mechanism 3 extends outward due to the resistance of the soil, and the top shallow fixing body 307 grips the foundation more firmly to ensure the stability of the foundation. The shallow fixing body 307 is close to the soil surface. When the weather rains, the soil absorbs water and becomes soft, filling the gap between the soil and the shallow main rod 301 caused by vibration. This can effectively prevent the gap between the foundation body and the soil surface from becoming larger during vibration.

[0041] The shallow fixing mechanism 3 also includes a shallow outer plate 308 fixed to the outer wall of the shallow main rod 301. A shallow blocking frame 309 is fixedly connected to the top outer wall of the shallow outer plate 308. A shallow outer body 310 is fixedly connected to the outer wall of the shallow hole 304. A soil covering groove 311 is opened on the inner wall of the shallow outer body 310. The soil covering groove 311 is set inside the invention. When the foundation is deeply buried and the mud cools down, the soil covering groove 311 can increase the contact area of ​​the equipment and ensure the stability of the foundation. A condensation plate 102 is fixedly connected to the outer wall of the equipment. The temperature difference causes water droplets to condense on the entire outer plate 101. The water droplets mix with the external soil through the water inlet hole 107 to fill the internal gaps.

[0042] One specific application of this embodiment is:

[0043] When the equipment is fixed, the shallow fixing mechanism 3 extends outward due to soil resistance, making the top shallow fixing body 307 grip the foundation more firmly to ensure foundation stability. Since the shallow fixing body 307 is close to the soil surface, after rainfall, the soil absorbs water and becomes soft, filling the gaps between the soil and the shallow main rod 301 caused by vibration. The relatively soft soil can effectively absorb vibration, preventing the gap between the foundation body and the soil surface from widening. Furthermore, after the foundation is deeply buried, the inner soil trench 311 can increase the stability of the equipment. To ensure foundation stability, a condensation plate 102 is fixedly connected to the outer wall of the device. The temperature difference causes water droplets to condense on the outer plate 101, which mix with the external soil through the water inlet hole 107, filling the internal gaps. After the device is inserted into the soil, the deep soil inlet hole 204 is filled with soil. The inner middle expansion body 211 and inner expansion body 212 expand outward due to the pressure of the soil, increasing the internal resistance. The deep outer plate 207 contracts inward during deep burial and extends outward after vibration caused by various daily factors, increasing the resistance of the foundation.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
