Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering, and in particular to a guide frame for plastic steel sheet piles. Background Technology

[0002] Plastic-coated steel sheet piles are a new type of building material, made by extruding a mixture of high-polymer reinforced composite materials and various additives. They are increasingly widely used in engineering projects such as riverbank protection, foundation pit support, and seepage prevention. However, during construction, due to the material's low rigidity and poor resistance to deformation, deformation, twisting, and displacement of the sheet piles often occur.

[0003] Existing plastic steel sheet pile guide frames all use four positioning piles driven into the foundation to fix the position of the guide frame, such as patent application number 202311286157.0. This type of guide frame is suitable for soil with good foundation bearing capacity and high consolidation, but not suitable for foundations formed by coastal reclamation. This type of foundation has high fluidity and low bearing capacity, and the positioning piles need to be driven into the strata very deep to play a fixing role. Utility Model Content

[0004] Purpose of the invention: The purpose of this utility model is to provide a guide frame for plastic steel sheet piles, which solves the problems of inconvenient installation and low efficiency of plastic steel sheet piles on highly fluid foundations.

[0005] Technical solution

[0006] A guide frame for plastic steel sheet piles includes a high frame and a bottom frame. The high frame and the bottom frame are used to insert plastic steel sheet piles. A plurality of uprights are fixedly connected between the high frame and the bottom frame. Side rods are connected between the side walls of the high frame and the side walls of the bottom frame. The side rods abut against the ground. Support plates and fixing plates for support are connected to the side rods.

[0007] Furthermore, a screw is threaded onto the side rod, the screw passes through the side rod, and the end of the screw is rotatably connected to the support plate.

[0008] Furthermore, a rocker arm is rotatably connected to the side rod, and the rocker arm is rotatably connected to the fixed disk.

[0009] Furthermore, the width of the high frame is greater than the width of the bottom frame, and the side rods are inclined.

[0010] Furthermore, a long rod is fixedly installed on the inner wall of the high frame, and the long rod and the bottom frame are located in the same vertical plane.

[0011] Furthermore, a fixing rod connects the long rod and the side rod of the tall frame.

[0012] Beneficial effects: By using the structural tooth groove as a base support, the positioning piles of the guide frame are eliminated. By adjusting the support plate on the side rod and the contact plate of the fixing plate with the inner wall of the tooth groove, the guide frame can be fixed and the guiding function of the guide frame can be realized.

[0017] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figs. 1-3 As shown, a guide frame for plastic steel sheet piles includes a high frame 21 and a bottom frame. The high frame 21 and the bottom frame are fixedly connected by vertically arranged uprights 22. Both the high frame 21 and the bottom frame are hollow to facilitate the installation of plastic steel sheet piles. During installation, the plastic steel sheet piles will vertically pass through the high frame 21 and the bottom frame.

[0019] Both the high frame 21 and the bottom frame are square structural frames. The high frame 21 and the bottom frame are the same length, but the width of the high frame 21 is longer than that of the bottom frame. The high frame 21 and the bottom frame are connected by the uprights 22 to form a guide frame. At the same time, the high frame 21 and the bottom frame are fixedly connected to the sides of the side rods 28. The side of the guide frame forms a trapezoid. The toothed grooves used in construction will be constructed into the shape of trapezoidal grooves. The side walls of this type of toothed groove have strong load-bearing capacity, which makes it easier to fix the guide frame for installing plastic steel sheet piles, thereby improving the installation efficiency of plastic steel sheet piles.

[0020] Furthermore, the width of the high frame 21 is much greater than the width of the bottom frame, while the width of the bottom frame is adapted to the width of the plastic steel sheet pile. To prevent the plastic steel sheet pile from tilting due to its top being heavier than its bottom, the high frame 21 is equipped with two long rods 33, which are arranged parallel to each other inside the high frame 21. At the same time, the long rods 33 and the side rods of the bottom frame are on the same vertical plane. The long rods, together with the high frame 21, form a side cavity 31 and a positioning cavity 32. The positioning cavity 32 is located at the center of the high frame 21. There are two side frames 31, which are located on both sides of the positioning frame 32. The positioning frame 32 is the same size as the bottom frame, which facilitates the insertion of the plastic steel sheet pile.

[0021] The side cavity 31 is also equipped with a fixing rod 35, which is perpendicular to the long rod 33. The fixing rod 35 can improve the strength of the long rod 33 and ensure the stability of the plastic steel sheet pile.

[0022] The guide frame is placed in the toothed groove constructed in the soft soil foundation during operation. The side wall of the toothed groove is made of concrete, which can provide sufficient support. The side rod 28 abuts against the side wall of the toothed groove. In order to disperse the pressure of the contact between the side rod 28 and the toothed groove and improve the stability of the guide frame, the side rod 28 is equipped with a support plate 26 and a fixing plate 24.

[0023] The support plate 26 is installed on the lower side of the side rod 28. A screw 25 is threaded onto the side rod 28. The end of the screw 25 is rotatably connected to the support plate 26. When the screw 25 rotates, the support plate 26 will follow the end of the screw 25 away from or close to the side wall of the tooth groove. The support plate 26 can be a structure with a large contact surface, such as a disc. The guide frame is supported by the contact between the support plate 26 and the tooth groove, thereby stabilizing the guide frame and realizing the position adjustment and fixation of the frame.

[0024] Meanwhile, a rocker arm 23 is connected to the upper side of the side rod 28. The end of the rocker arm 23 is rotatably connected to the fixing plate 24. The fixing plate 24 has reserved holes for drilling expansion bolts to fix it to the pad concrete, which is mainly used to compensate for the situation where the support plate cannot stabilize the frame of the guide frame.

[0025] In this application, the high frame 21, the bottom frame, the side rod 28, and the long rod 33 are all galvanized square tubes, which are welded together to ensure overall strength.

[0026] During installation, follow these steps: after the base soil leveling is inspected and approved, lay and compact the cement-soil bedding layer in layers.

[0027] According to the construction drawings, the axis, upper edge line and lower edge line of the tooth groove are excavated using a backhoe excavator and the slope is trimmed.

[0028] Pour a concrete foundation layer, but do not pour concrete at the bottom of the tooth groove to facilitate the installation of plastic steel sheet piles. Pay special attention to the flatness and structural dimensions of the tooth groove area.

[0029] Mark the two side lines of the plastic steel sheet pile at the bottom of the tooth groove;

[0030] Install the guide frame to align the lower limit steel pipe with the measured edge line, and fix the lower position of the frame by rotating the bolts so that the adjustable support plate at the bottom presses against the concrete pad at the bottom of the tooth groove.

[0031] The verticality of the scaffold is checked using a theodolite. The verticality is ensured by adjusting the upper adjustable supports, and then the reinforcing legs are lowered. Whether the pads for the reinforcing legs need to be fixed to the concrete base with expansion bolts depends on the stability of the scaffold during installation.

[0032] The first positioning sheet pile is driven. The pile driver uses a hydraulic head to clamp and deliver the sheet pile, then lifts it to check its verticality and stability. Once the requirements are met, the sheet pile is laid flat on a level surface, and the joint between the sheet pile and the plastic sheet pile is cleaned manually with a brush, especially removing any mud.

[0033] After the pile driving plate is cleaned, workers lift the plastic steel sheet piles and place them into the pile driving plate, ensuring the top of the sheet pile is aligned with the top of the plate. They then fine-tune the position of the sheet piles to ensure a tight fit. Once inspected and approved, workers use U-shaped clamps to secure the sheet piles to the pile driving plate at the bottom, and use clips on both sides at 2-meter intervals for further securing.

[0034] After the plastic steel sheet piles are installed, the pile driver slowly lifts the pile delivery plate until the bottom end leaves the ground and then stops. After checking that the installation is secure, the plastic steel sheet pile is hoisted to the guide frame. The bottom end of the sheet pile is manually adjusted to enter the guide frame. The verticality of the plastic steel sheet pile is checked with a theodolite. After the adjustment is completed, the pile driver starts driving the pile. While driving the pile, the clips on both sides are removed. The surveyor uses a theodolite to check the verticality of the pile body during the driving process.

[0035] After the first positioning pile is driven and inspected and approved, the construction of the second plastic steel sheet pile begins. The second plastic steel sheet pile is manually aligned with the locking joint of the first pile before the pile driver slowly drives it down. Before each plastic steel sheet pile is installed, the pile plate must be cleaned, and so on.

[0036] After the effective driving range of the guide frame is completed, the guide frame is manually lifted and moved forward, leaving 1-2 plastic steel sheet piles at the tail end as a reference, and the plastic steel sheet piles are driven in accordance with the above method.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
