Technical Field

[0001] The present invention relates to an anti-slip support structure, in particular to an H-shaped anti-slip pile support structure with a lower circle and an upper part, and a construction method thereof. Background Art

[0002] In building slope engineering, for structures built in hard rock strata or on river banks, it is often necessary to fill some earth to meet the planned elevation requirements of the outdoor floor of the structure. At the same time, the structure is located within the potential sliding range of the slope and requires slope support.

[0003] Traditional anchor support cannot be applied to fill slopes. Large-diameter, ultra-long cantilever anti-slide piles are difficult to drill holes in slightly weathered hard rock formations, are inefficient, and lack a good pressure relief effect, which reduces their service life. Summary of the Invention

[0004] The purpose of the present invention is to provide an H-shaped anti-slip pile support structure above the lower circle in order to solve the above problems, which improves construction efficiency and reduces costs, and can play a good pressure relief role, effectively making the support structure more stable, extending its service life, and having high safety performance.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: an H-shaped anti-slip pile support structure above the lower circle, comprising an upper support structure, an intermediate support structure and a lower support structure, characterized in that: the lower support structure is a portal steel frame structure, which includes circular piles arranged in front and behind, connecting beams arranged horizontally on the top of the front and rear rows of piles, and continuous hidden beams arranged longitudinally on the top of the front and rear rows of piles; the intermediate support structure includes a mouth-shaped frame structure and a lower retaining panel, wherein the mouth-shaped frame structure is composed of two rows of square columns and connecting beams, and the two rows of square columns are on the same vertical axis as the two rows of circular piles; the upper support structure includes a row of square columns and an upper retaining panel, and the square columns of the upper support structure are the same as the square columns of the intermediate support structure and are on the same vertical axis.

[0006] Preferably, the intermediate support structure also includes a plurality of pressure relief components, which are installed on the mouth-shaped frame structure at a certain distance. The pressure relief components include a pressure relief plate, a slide, a closing plate and a locking mechanism. The closing plate includes two side closures, an upper closing plate and a lower closing plate. The closing plate and the lower retaining panel are fixed on the mouth-shaped frame structure to form a closed space. The lower closing plate is provided with a slide, and the pressure relief plate translates along the slide in the closed space. The locking mechanism is installed above the upper closing plate, and the locking mechanism locks the pressure relief plate. The locking mechanism includes a power self-locking component, a base, a telescopic arm, a support arm and a fixed plate. The fixed plate is installed in the center of the pressure relief plate, and the support arm is fixed on the fixed plate. The power self-locking component is installed on the base, and the power self-locking component can lock the telescopic arm.

[0007] Preferably, a lifting hole is provided on the upper closing plate, and the lifting hole is T-shaped to facilitate the coordinated operation of the telescopic arm and the support arm, and the pressure relief plate can extend through the lifting hole to rise upward.

[0008] Preferably, the locking mechanism further comprises a hydraulic lifting device, one end of the telescopic arm is fixed on the hydraulic lifting device, and the lifting of the hydraulic lifting device can drive the pressure relief plate to rise from the lifting hole.

[0009] Preferably, a plurality of soil drainage holes are provided in the middle of the lower retaining panel.

[0010] Preferably, the pressure relief plate is a steel plate.

[0011] Preferably, a roller is provided at the bottom of the pressure relief plate, and the roller moves in coordination with the slide groove.

[0012] During construction, the specific construction methods are: S1: Install the H-type anti-slip pile support structure. First, use drilling equipment to drill holes at the designed location of the slope, and then pour concrete to form the lower support structure. The mouth-shaped frame structure and the lower retaining panel are rigidly connected on the top of multiple circular pile rows. The mouth-shaped frame structure consists of two rows of square columns and connecting beams. After the middle support structure is installed, the upper support structure is constructed. The upper support structure (including a row of square columns and the upper retaining panel) is connected through the upper, middle and lower support structures to form the H-type anti-slip pile support structure above the lower circle. S2: Installing the pressure relief assembly. The H-shaped anti-slide pile support structure is arranged along the supporting slope. Pressure relief assemblies are intermittently arranged along the slope direction in the middle supporting structure. Each pressure relief assembly includes a pressure relief plate, a chute, a closing plate, and a locking mechanism. When the lateral soil undergoes a slight settlement, the soil squeezes the pressure relief plate, causing it to slide to a certain position under the cooperation of the support arm and the telescopic arm, allowing the soil to move within a certain range. After stabilization, the pressure relief plate is locked by the locking mechanism. S3: Perform pressure relief operation. When the soil pressure reaches a certain level, the lateral soil pressure can be released. Through the action of the hydraulic lifting device, the telescopic arm is lifted, so that the telescopic arm drives the support arm to pull the pressure relief plate, so that the pressure relief plate is lifted out of the lifting hole, completing the soil pressure relief operation. At this time, the soil will partially overflow from the soil discharge hole of the lower retaining panel, thereby achieving pressure relief while ensuring the stability of the overall support structure.

[0013] The beneficial effects of the present invention are: (1) The plurality of the above-mentioned columns and the plurality of the second columns are connected in an "H"-shaped stack, which is beneficial to increasing the anti-slip effect and making the support effect better. In addition, with the cooperation of the plurality of the above-mentioned beams and the plurality of the above-mentioned connecting beams, it is beneficial to rigidly connect the plurality of the above-mentioned columns and the plurality of the second columns, so that the overall structure is more solid and stable, which is beneficial to reinforcing the river bank slope and avoiding the risk of anchor rod settlement and fracture. At the same time, the construction is convenient, saving construction time and construction costs. Through the installation of the pressure relief plate, with the cooperation of the telescopic arm, the support arm and the power self-locking component, it is beneficial to play a role in pressure relief.

[0014] (2) By setting up a pressure relief component, the soil layer is allowed to deflect under the condition of meeting the soil pressure load, satisfying the dynamic pressure relief process. The fixation after stabilization is ensured by locking the pressure relief plate. When the soil pressure exceeds the load, the pressure relief plate is moved to the lifting hole position and removed. (At this time, the water pressure is discharged through the soil discharge hole of the lower retaining panel, the pressure of the soil layer is relieved and the stability of the overall structure is ensured by the support of the lower retaining panel.

[0025] When the present invention is used, during construction, the specific construction method is: S1: Installing the H-type anti-slip pile support structure: First, use drilling equipment to drill holes at the designed location of the slope, and then pour concrete to form the lower support structure 3. Rigidly connect the mouth-shaped frame structure 21 and the lower retaining panel 22 on top of the multiple circular pile rows 31, where the mouth-shaped frame structure 21 is composed of two rows of square columns 211 and a connecting beam 212.
