Abstract
Description
Technical Field
[0001] The patent of this invention relates to the field of foundation technology, specifically a deep ground pile arch plate force dispersion construction method. Background Art
[0002] The foundation is an important part of the building. Only when the foundation is stable can the building above it be used for a longer time. Due to some reasons such as the weight of the foundation and the building above, pressure is exerted on the natural foundation, which will cause a series of impacts that undermine the stability of the building, such as foundation settlement. Foundation settlement is inevitable. The degree of settlement of a foundation depends largely on the compressive strength and stability of the foundation and the pressure of the foundation on the natural foundation.
[0003] In the prior art, foundations include independent foundations, strip foundations, pile foundations, raft foundations and box foundations, etc.; in the construction process, raft foundations are more commonly used; after the raft foundation is built, there is a certain distance between the ground beams between the two columns, and the load is large due to the relatively weak bearing capacity of the foundation at the location, groundwater and the weight of the house, which causes the ground beams to tilt or sink, affecting the house.
[0004] In view of the deficiencies in the prior art, the present invention provides a deep pile arch slab force dispersion construction method that can improve the bearing capacity of the ground beam of the raft foundation.
[0005] To achieve the above purpose, the present invention provides the following technical solutions: A deep pile arch plate force dispersion construction method, characterized by comprising the following steps: Step 1: Construction workers need to sink reinforced concrete piles into the ground of the required building through equipment. Several reinforced concrete piles are set in a matrix structure, and the upper ends of the reinforced concrete piles need to be exposed above the ground; Step 2: The construction workers cast a reinforced concrete horizontal plate between every two adjacent reinforced concrete piles. The bottom surface of the reinforced concrete horizontal plate is located above the ground, and both sides of the reinforced concrete horizontal plate are fixedly connected to the reinforced concrete piles. Step 3: Connect the arched plate to the top surface of the reinforced concrete horizontal plate, and fix the two sides of the arched plate to the reinforced concrete piles; Step 4: Cast the bottom plate, and the top of the arch plate is fixedly connected to the bottom plate; Step 5: Carry out the construction of ground beams, columns and foundation.
[0006] Preferably, in step one, a slot is provided on the top of each reinforced concrete pile, and correspondingly, in step four, when the base plate is cast, an insert block adapted to the slot is formed on the bottom surface of the base plate.
[0007] Preferably, the cross-sections of the insert block and the slot are arranged in a trapezoidal shape.
[0008] Preferably, in step three, a second pouring layer is poured and filled between the inner wall of the arched plate and the reinforced concrete transverse plate.
[0009] Preferably, in step 4, when pouring the base plate, a first pouring layer is poured and filled between the outer wall of the arched plate and the base plate and the reinforced concrete piles.
[0010] Compared with the prior art, the present invention has the following beneficial effects: The present invention achieves deep fixation by arranging a number of reinforced concrete piles corresponding to the nodes of the ground beam at the bottom of the bottom plate, effectively reducing the instability caused by precipitation or weak soil and avoiding the sinking of the bottom plate; by arranging arched plates on both sides of each adjacent reinforced concrete pile, when the foundation is under pressure, the arched plates can convert the pressure received into thrust to both sides along the arch axis. This force conversion can make the load no longer concentrated on a certain point or several sections, but evenly distributed to the entire structure by the arched plates, thereby increasing the bearing capacity of the ground beam and reducing the probability of sinking. The structure is simple, easy to operate and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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, not all of the embodiments.
[0014] like Figures 1 to 6 As shown, a deep pile arch plate dispersion force construction method comprises the following steps: Step 1: Construction workers need to use equipment to sink reinforced concrete piles 4 into the ground of the required building. Several reinforced concrete piles 4 are arranged in a matrix structure, and the upper ends of the reinforced concrete piles 4 need to be exposed above the ground. It should be noted that the nodes of the reinforced concrete piles 4 and the ground beams 2 correspond one by one.
[0015] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a slot 8 is provided on the top of each reinforced concrete pile 4. In this embodiment, the number of the slots 8 is two.
[0016] Step 2: The construction workers cast the reinforced concrete horizontal plate 6 between every two adjacent reinforced concrete piles 4. The bottom surface of the reinforced concrete horizontal plate 6 is located above the ground, and both sides of the reinforced concrete horizontal plate 6 are fixedly connected to the reinforced concrete piles 4.
[0017] Step three: connect the arched plate 7 to the top surface of the reinforced concrete transverse plate 6, and fix the two sides of the arched plate 7 to the reinforced concrete piles 4; at the same time, pour and fill the second pouring layer 11 between the inner wall of the arched plate 7 and the reinforced concrete transverse plate 6.
[0018] Step 4: Cast the bottom plate 1, the top of the arch plate 7 is fixedly connected to the bottom plate 1, and when casting the bottom plate 1, the bottom surface of the bottom plate 1 forms an insert 9 adapted to the slot 8. In addition, the cross-sections of the insert 9 and the slot 8 are set in a trapezoidal shape. When casting the bottom plate 1, the first casting layer 10 is cast and filled between the outer wall of the arch plate 7 and the bottom plate 1 and the reinforced concrete piles 4.
[0019] By utilizing the fit between the plug block 9 and the slot 8 and fixing with concrete, the connection between the base plate 1 and the reinforced concrete pile 4 can be made more stable, and the bearing capacity can be further shared; setting two slots 8 further increases the connection stability; the trapezoidal plug block 9 and slot 8 further utilize the trapezoidal cross-section to increase the contact area, thereby forming better stability.
[0020] At the same time, the present invention can ensure that the outer wall and the inner wall of the arch plate 7 are not completely suspended by providing the first pouring layer 10 and the second pouring layer 11, thereby ensuring the conversion pressure and stability.
[0021] Step 5: Carry out the construction of ground beam 2, column 3 and foundation 5.
[0022] By arranging a number of reinforced concrete piles 4 corresponding to the nodes of the ground beam 2 at the bottom of the bottom plate 1, the bottom plate 1 is supported and deeply fixed, and the instability caused by precipitation or weak soil is effectively reduced; by arranging arch plates 7 on both sides of each adjacent reinforced concrete pile 4, when the foundation 5 is subjected to pressure, the arch plates 7 can convert the pressure (downward force) it receives into thrusts to both sides along the arch axis. This force conversion can make the load no longer concentrated on a certain point or several sections, but evenly distributed to the entire structure, thereby increasing the bearing capacity of the ground beam 2 and reducing the probability of subsidence.
[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
