[0009] Furthermore, a pile-side anchor bar is embedded in the middle of the high pile, and one end of the pile-side anchor bar extends into the ground tie beam and is connected to the main reinforcement of the ground tie beam.

[0010] Furthermore, the high pile and the low pile are both precast square piles.

[0011] Furthermore, the precast square pile includes:

[0012] Multiple concrete pile segments are coaxially arranged, and a plug is formed at the upper end of each concrete pile segment. The plug is coaxially arranged with the concrete pile segment, and the outer diameter of the plug is smaller than the outer diameter of the concrete pile segment.

[0023] Reference Figures 1 to 3 As shown, this utility model provides a pile-column integrated wall structure, including a high pile 1, a low pile 2, a ground connecting beam 3, and a guardrail 4.

[0024] In this embodiment, there are multiple tall piles 1 and multiple short piles 2.

[0025] Multiple high piles 1 are spaced apart along the length of the construction path of the enclosure wall. The lower part of each high pile 1 is embedded in the foundation. The upper part of each high pile 1 extends above the ground.

[0026] Multiple short piles 2 are embedded in the foundation. The multiple short piles 2 are set along the length of the construction path. At least one short pile 2 is set between two adjacent tall piles 1.

[0027] The ground tie beam 3 is cast into the ground. The ground tie beam 3 connects two adjacent high piles 1. The top of the low pile 2 is supported and connected to the ground tie beam 3.

[0028] The guardrail 4 is installed on the ground tie beam 3 and connected between the upper parts of two adjacent high piles 1.

[0029] The pile-column integrated wall structure of this utility model uses high and low piles 2 pressed into the foundation, then pours ground connecting beams 3 and installs guardrails 4 to form a pile-column integrated wall, avoiding trench excavation and damage to adjacent roads, while improving construction progress and saving costs.

[0030] An anchor bar is embedded in the middle of the high pile 1. One end of the anchor bar extends into the ground tie beam 3 and is connected to the main reinforcement of the ground tie beam 3.

[0031] As a preferred implementation method, the high pile 1 and the low pile 2 are precast square piles.

[0032] Specifically, precast square piles include: concrete pile section a, joint pipe b, and locking pin c.

[0033] Multiple concrete pile segments a are coaxially arranged. A plug h is formed at the upper end of each concrete pile segment a, and plug h is coaxially arranged with the concrete pile segment a. The outer diameter of plug h is smaller than the outer diameter of the concrete pile segment a.

[0034] Connector pipe b, one end of connector pipe b is fitted onto the lower end of concrete pile section a. The plug h of the adjacent concrete pile section a is inserted into the other end of connector pipe b.

[0035] The locking pin c has a T-shaped notch d at the other end of the connector tube b. The plug h has a T-shaped through hole. The T-shaped through hole is aligned with the T-shaped notch d. The upper end of the concrete pile section a has an inverted T-shaped through hole. The T-shaped through hole and the inverted T-shaped through hole connect to form an I-shaped through hole f. The locking pin c is inserted into the T-shaped notch d and the I-shaped through hole f. The cross-sectional shape of the locking pin c matches the cross-sectional shape of the I-shaped through hole f.

[0036] A diaphragm d is formed inside the joint pipe b. Anchor bars g are connected to the diaphragm d. Anchor bars g are embedded in the lower end of the concrete pile section a.

[0037] The construction process of the integrated pile and column wall structure of this utility model is as follows: 1. Precast square pile fabrication → 2. Pressing the precast square piles → 3. Site leveling → 4. Construction of ground tie beams → 5. Laying facing bricks.

[0038] 1. Precast square pile fabrication.

[0039] Precast square piles are manufactured by a processing plant, and the precast square pile manufacturing process requires the provision of connecting steel bars for the ground tie beam.

[0040] 2. Pressing precast square piles.

[0041] (1) Positioning and hoisting of piles.

[0042] An excavator was used to lift the precast square piles to the pile location, with the pile tip aligned with the marked point.

[0043] (2) Clamping and straightening.

[0044] The modified clamping mechanism fixes the pile body, and the verticality of the pile is adjusted by the excavator arm (it needs to be monitored with a theodolite, and the deviation should be ≤0.5%).

[0045] (3) Pressure-driven pile driving.

[0046] The modified hydraulic system is used to slowly press down the pile body, controlling the pile pressing speed (1-2 m / min), and recording the pile pressing force and pile top elevation in real time.

[0047] 3. The site is flat.

[0048] Wooden stakes were set up and the design elevation was marked, followed by manual leveling of the site.

[0049] 4. Construction of ground tie beam.

[0050] (1) Reinforcing bar installation.

[0051] The positions of the main reinforcement joints are staggered (welded joints ≥35d and ≥500mm, lapped joints ≥1.3 times the lap length).

[0052] The spacing of the stirrups conforms to the drawings, and the four-legged stirrups must hook onto the main reinforcement bars.

[0053] The pile side anchor bars are welded to the main reinforcement of the ground tie beam, with an anchorage length ≥35d and a weld joint stagger rate of 50%.

[0054] Protective layer control: Use concrete blocks or plastic retaining rings to ensure that the bottom protective layer is ≥40mm and the side layer is ≥25mm.

[0055] (2) Template installation.

[0056] Side formwork support: Use wooden or steel formwork, and reinforce the back ribs with square timber or steel pipes, with a spacing of ≤500mm.

[0057] Support system:

[0058] When the height of the ground tie beam is ≤600mm, it can be fixed with diagonal bracing;

[0059] When the height is greater than 600mm, tie bolts (spacing ≤ 600mm) should be installed to prevent bulging.

[0060] Acceptance: Check the verticality of the template (deviation ≤3mm / m) and the cross-sectional dimensions (deviation ±5mm).

[0061] (3) Concrete pouring.

[0062] Before pouring: Clean the debris inside the formwork and sprinkle water to moisten the subbase and formwork.

[0063] Casting process:

[0064] The pouring is done in layers, with each layer ≤500mm thick, and compaction is achieved using an immersion vibrator (quick insertion and slow withdrawal, with no air bubbles overflowing).

[0065] The top surface of the beam is leveled using a screed, and the surface is finished with a wooden trowel. Before initial setting, it is troweled twice to prevent cracking.

[0066] Construction joint treatment: It is left in the middle 1 / 3 of the span. After roughening and cleaning, it is brushed with cement slurry before pouring.

[0067] (4) Curing and demolding.

[0068] Curing: Cover with a film within 12 hours after pouring or water for curing for ≥7 days.

[0069] Formwork removal: Remove the side formwork after the concrete strength reaches ≥1.2MPa (approximately 24 hours) to avoid damage to the edges and corners.

[0070] 5. Lay facing tiles.

[0071] (1) Measurement and layout: Based on the dimensions of the wall and the specifications of the facing bricks, measure and lay out the lines on the base layer to determine the laying position and layout of the facing bricks. Starting from one end of the wall, mark the horizontal and vertical control lines according to the design requirements, and set control points at regular intervals to ensure the flatness and verticality of the facing bricks.

[0072] (2) Pre-layout of bricks: Before the actual paving, pre-layout of bricks should be carried out. According to the actual size of the wall and the specifications of the bricks, the arrangement of the bricks should be reasonably arranged to avoid non-whole bricks or small and narrow bricks as much as possible. For non-whole bricks that cannot be avoided, they should be placed in inconspicuous positions, such as the bottom or end of the wall.

[0073] (3) Laying facing bricks: Apply an adhesive layer (4-8mm thick) to the back of the bricks using a notched scraper. Then, gently place the facing bricks on the adhesive material according to the pre-arranged brick positions. Gently tap them with a rubber mallet to ensure they are firmly bonded to the base layer. Adjust the flatness and verticality of the facing bricks. Leave a certain gap between the facing bricks, with a gap width of 2-5mm, for grouting.

[0074] (4) Grouting: After the tiles are laid, wait 24 hours after the adhesive material has reached a certain strength before grouting. Use a special grouting tool to fill the gaps between the tiles with grout material to ensure that the gaps are filled, compacted, and the surface is flat and smooth.

[0075] (5) Curing: After the tiles are laid, they should be properly cured to avoid direct sunlight and wind and rain. Generally, the curing time should be no less than 7 days at room temperature.

[0076] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
