Description

TECHNICAL FIELD

[0001] The utility model relates to beam bench technology field, concretely relates to a beam bench foundation system of drainage. BACKGROUND

[0002] In the process of beam bench foundation construction, soft soil foundation often needs drainage treatment. Soft soil (such as silt, peat soil, marsh soil, etc.) has high compressibility and permeability, and is easy to become a flow state when the load exceeds the bearing capacity, leading to uneven stress, and further crack or settlement problems. In addition, the water in the soil forms mud, which is difficult to drain, and if not consolidated, it will affect the subsequent construction progress and bring safety hazards. Therefore, the soft soil foundation needs to be consolidated before construction.

[0003] Composite foundation is a common soft soil foundation treatment method in engineering, for example, CFG pile is punched into soil, and cushion layer is laid, so that soil and pile bear the upper load together. However, CFG pile has poor drainage, which leads to the need to set more pile to bear the upper structure during foundation construction, resulting in waste of construction resources.

[0004] For prefabricated beams, in addition to the bearing capacity and settlement deformation of the foundation affecting the quality of the prefabricated beam, the bench foundation, especially the enlarged end foundation, also affects the quality of the prefabricated beam. The existing enlarged end foundation is usually made of ordinary concrete, but it has the problems of weak bearing capacity and poor crack resistance. When the load is large during the beam production period, the foundation is prone to cracking and cannot bear the upper load. SUMMARY

[0005] The utility model aims at providing a beam bench foundation system with drainage function, which can use steel fiber reinforced concrete to make the enlarged end foundation during the production period of prefabricated beams to improve the strength of the enlarged end foundation and avoid poor cracking performance. By increasing the drainage channel in the CFG pile for drainage, the soil consolidation can be accelerated, the uneven settlement can be reduced, and the bearing capacity of the foundation soil can be improved.

[0015] Optionally, the gravel layer comprises:

[0016] a high-strength metal filter screen arranged outside the gravel layer;

[0017] a steel reinforcement cage arranged inside the gravel layer to avoid relative displacement of the gravel.

[0026] Please refer to Figure 1 and Figure 2 A beam manufacturing pedestal foundation system capable of draining according to a preferred embodiment of the present application comprises a CFG pile and an enlarged end foundation. The CFG pile comprises a gravel layer 1, a pile body 2 arranged above the gravel layer 1, and a drainage channel 3 arranged in the pile body 2 and extending into the gravel layer 1 at the bottom. The enlarged end foundation is arranged above the CFG pile, and the enlarged end foundation is made of steel fiber reinforced concrete.

[0027] According to the scheme of the embodiment of the utility model, the steel fiber concrete is used to make the enlarged end foundation in the prefabricated beam production cycle, so that the strength of the enlarged end foundation is improved, the problem of poor cracking performance is avoided, and a good construction environment is provided for the later beam manufacturing period. The steel fiber in the steel fiber concrete is recycled waste steel industrial products, such as waste small steel bars, waste iron nails and the like, which not only reduces the cost of the enlarged end foundation, but also improves the utilization rate of steel, and forms the ecological cycle of steel. The drainage channel 3 is arranged in the CFG pile to drain water, so that the purpose of soft soil drainage consolidation is achieved, the bearing capacity of the CFG pile is further improved, and the uneven settlement after construction is reduced, so that a better foundation bearing capacity is provided for the beam manufacturing pedestal.

[0028] The following will be described in detail with specific embodiments:

[0029] Please refer to Figure 1 The drainage channel 3 is arranged at the central axis position of the pile body 2, and gravel is arranged in the drainage channel 3. By arranging the gravel with large porosity in the drainage channel 3, the capillary phenomenon of water and the existing water pressure difference are utilized to make the water automatically rise to the water outlet pipe, which helps to optimize the drainage effect, enhance the permeability of the drainage channel 3 to ensure smooth water flow, promote effective water discharge, accelerate soil consolidation and improve the foundation bearing capacity. At the same time, the gravel layer 1 can prevent fine soil or silt from entering the drainage channel 3, avoid blockage and ensure the long-term effectiveness of drainage. In addition, the drainage channel 3 is arranged at the central axis position of the pile body 2, which not only optimizes the water flow path, but also enhances the stability of the drainage channel 3 in the soil, which helps to improve the stability of the entire beam manufacturing pedestal foundation system.

[0030] Please refer to Figure 1 And Figure 2 The bottom of the drainage channel 3 is provided with a filter screen 31 for drainage filtration. The arrangement of the filter screen can ensure the smoothness of the drainage channel 3, prevent gravel or soil particles from blocking the drainage channel 3, and ensure the long-term effectiveness of the drainage system. This helps to improve the drainage efficiency and avoid the accumulation of water in the soil due to blockage.

[0031] Please refer to Figure 1 The beam manufacturing pedestal foundation system further comprises a water collecting container 4 and a water outlet pipe 5, one end of the water outlet pipe 5 is connected with the top of the drainage channel 3, and the other end of the water outlet pipe 5 is connected with the water collecting container 4. The water outlet pipe 5 extends obliquely from one end to the other end, and a water pump is arranged at the water collecting container 4 to pump water. By arranging the water collecting container 4 in cooperation with the water outlet pipe 5, the water in the drainage channel 3 can be effectively collected and discharged, and a stable environment is provided for construction. By obliquely arranging the water outlet pipe 5, it can be ensured that the water can flow naturally to the water collecting container 4, and the drainage efficiency is improved. The arrangement of the water pump provides the ability of active drainage, further ensures the water management during construction, and avoids the negative influence of water accumulation on the foundation.

[0032] See Figure 1 and Figure 2 The gravel layer 1 includes high-strength metal filter 6 and steel cage 7, the high-strength metal filter 6 is set outside the gravel layer 1, the steel cage 7 is set inside the gravel layer 1 to avoid the relative displacement of the gravel. The use of the steel cage 7 after the waterproof layer is smeared can effectively fix the gravel and avoid the displacement of the gravel, thereby maintaining the stability of the gravel layer 1 and the effectiveness of the drainage channel 3. The high-strength metal filter 6 can ensure that the permeability of the gravel layer 1 is not affected, while preventing soil particles from entering and maintaining the drainage function of the soil body.

[0033] The construction process of the drainable beam bench foundation system is as follows:

[0034] The traditional hole-forming process is adopted to drill the hole. After the hole is formed, multiple layers of high-strength metal filter 6 and steel cage 7 are placed in the hole, and then gravel is poured to form the gravel layer 1. After the gravel layer 1 reaches a certain height, the drainage channel 3 filled with gravel is placed in it and the gravel continues to be poured. After the gravel layer 1 reaches the set height, the concrete is poured into the hole according to the construction process of the CFG pile to form the pile. When the concrete reaches the same height as the water collector 4, the inclined water outlet pipe 5 is placed in the hole, and the water collector 4, the drainage channel 3 and the water outlet pipe 5 are connected. Continue to pour concrete into the hole, and stop when the CFG pile 2 reaches the required length. After the CFG pile 2 is formed, the expanded end foundation of the beam bench is built on the upper part of the pile 2 using steel fiber reinforced concrete.

[0035] Among them, the drainage channel 3 is set to extend into the gravel layer 1, which can effectively promote the drainage of water from the soil body and avoid the lack of bearing capacity of the soft soil foundation caused by water accumulation. The setting of the drainage channel 3, combined with the high permeability of the gravel in the drainage channel 3, enhances the overall drainage effect, which helps to accelerate the consolidation of the soil body and reduce settlement and uneven settlement. The existence of the gravel layer 1 improves the combination effect of the soil body and the pile 2, and the pouring of the concrete ensures the strength and stability of the pile, providing a solid support for the upper foundation structure. During the pouring of the concrete, when the concrete reaches the same height as the water collector 4, the water outlet pipe 5 is installed and the drainage system is connected to guide the water to the water collector 4. This can ensure that the water is drained in time to avoid water accumulation affecting the consolidation of the foundation and the pile 2. The inclined design of the water outlet pipe 5 helps to utilize gravity flow and reduce energy consumption of the water pump. Continue to pour concrete until the CFG pile reaches the required length, which ensures the stability and bearing capacity of the pile 2, and also makes the drainage channel 3 and the gravel layer 1 completely integrated inside the pile 2. The completion of this step means that the pile body has been completed, providing a good foundation for the subsequent expansion foundation construction.

[0036] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as within the scope of the present disclosure.

It should be pointed out that, for ordinary skilled in the art, under the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
