Description

Technical Field

[0001] This invention relates to the field of square pile construction technology, specifically to an anchor static pressure pile construction mechanism and a novel construction process. Background Technology

[0002] When the foundation of a new building is a pile foundation, traditional pile foundation construction techniques often cannot meet the requirements of vibration-free and space-constrained high-tech industrial parks. Therefore, the traditional anchor static pressure pile construction technique can be used. However, this technique requires that holes be reserved in the pile cap. After the anchor static pressure piles are driven in, the pile sealing treatment is carried out. When the foundation is subjected to large loads, the pile sealing node is a weak node, and the highest compressive strength of C30 concrete is only 34 N / mm². 2 The characteristic value of the design bearing capacity of a single pile is 650 kN, and the area of ​​the pile sealing node is approximately 400,000 mm². 2 ;

[0003] Given that concrete strength increases with age and is also greatly affected by concrete quality, and that most projects require tight deadlines, if the superstructure is constructed too quickly after the foundation is completed, the foundation load may increase rapidly in a short period of time, potentially causing damage to the pile cap joints. This could result in fragile pile cap joints and affect the safety of the building structure. Summary of the Invention

[0004] The purpose of this invention is to provide a static pressure pile construction mechanism and a novel construction process to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a static pressure pile construction mechanism for anchor bolts, the static pressure pile construction mechanism comprising:

[0006] The first concrete layer has a pile hole vertically penetrating one side of it.

[0009] A reinforcing component, wherein the reinforcing component is movably inserted into the upper end of the square pile via a control component, and the reinforcing component includes a movable seat and several reinforcing bars;

[0010] A welding assembly is welded to the upper end of the anchor bolt assembly;

[0011] The second concrete layer is horizontally poured above the first concrete layer.

[0012] Preferably, the anchor bolt assembly includes four pre-embedded anchor bolts, which are vertically and symmetrically embedded in the first concrete layer near the four sides of the pile hole, and each of the four pre-embedded anchor bolts has an external thread at its upper end.

[0014] Preferably, several reinforcing bars are vertically inserted into the movable seat and the connecting block, and several guide grooves are symmetrically opened at the lower end of the casting groove. Several guide grooves are vertically inserted into the lower end of the reinforcing bars.

[0015] Preferably, the movable seat and the docking block are vertically connected by a grouting groove. The control component includes a control screw and an internal threaded cylinder. Several support rods are horizontally symmetrically arranged on the four sides of the internal threaded cylinder. The support rods are horizontally pre-embedded and inserted into the grouting groove of the movable seat on the four sides.

[0016] Preferably, the control screw is vertically inserted into the lower center of the casting groove via a bearing, and the upper end of the control screw is respectively connected to an internal threaded cylinder via a threaded connection.

[0017] Preferably, the control screw passes through the upper end of the internal threaded cylinder and has a control block. Each control block has an access slot at its upper end, and the access slot is a hexagonal structure.

[0018] Preferably, the welding assembly includes two welding rods, which are welded together at an angle. The external threads of the pre-embedded anchor rods are all provided with welding grooves. Four welding grooves are inserted into each side of the two welding rods, and the upper ends of several reinforcing steel bars on one side are welded to the lower ends of the welding rods.

[0019] Preferably, the upper end of the control block is lower than the upper end of the docking block, concrete slurry is poured into the casting groove, a hanging ring is movably inserted into the upper end of the control block, and the height of the upper end of the square column from the upper end of the first concrete layer is greater than 15 centimeters.

[0020] A novel construction process for anchored static pressure piles, applied to the aforementioned anchored static pressure pile construction mechanism, includes the following steps:

[0021] Step 1: Tie the reinforcing steel bars and pour the first concrete layer, and reserve pile holes;

[0022] Step 2: Pre-embed anchor rods corresponding to the dimensions of the static press, and install the static press equipment through external threads;

[0023] Step 3: Static pressure installation of the square pile. At this time, the movable seat and the reinforcing steel bars are retracted into the pouring groove, which will not affect the normal static pressure use of the static pressure machine.

After the installation is completed, it works with the welding component to strengthen the sealing connection and enhance its stability and safety. Moreover, there is no problem of insufficient pile driving reaction force in the overall construction process. It is simple to operate, easy to use, and suitable for widespread use.

[0048] A novel construction process for anchored static pressure piles, applied to the aforementioned anchored static pressure pile construction mechanism, includes the following steps:

[0049] Step 1: Tie the reinforcing bars and pour the first concrete layer 1, and reserve the pile hole 2;

[0050] Step 2: Pre-embed anchor rods 7 corresponding to the dimensions of the static press, and install the static press equipment through external threads 8;

[0051] Step 3: Static pressure installation of the square pile 3 is carried out. At this time, the movable seat 4 and the reinforcing steel bar 5 are retracted into the pouring groove 9, which will not affect the normal static pressure use of the static pressure machine.

[0052] Step 4: After the square pile 3 is installed, rotate the control screw 13 to control the movable seat 4 and the reinforcing steel bar 5 to rise.
