[0002] In today's urban construction, as urban land becomes increasingly scarce, more and more basements are built in new buildings. In foundation pit support projects, interlocking piles are often used as support structures. Before the interlocking pile construction, a guide wall needs to be built. The guide wall can provide guidance for the rotary drilling rig to drill holes and bear the load of the rotary drilling rig. It can also store mud and prevent the collapse of the soil wall at the hole mouth. It also serves as a benchmark for horizontal and vertical measurements during construction, and provides calibration for the placement of steel cages, concrete conduits, and rotary drilling rigs, as well as ensuring the geometric size and shape of the interlocking pile design.

[0023] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.

[0024] The utility model provides a recyclable interlocking pile prefabricated guide wall structure, comprising two wall panels 100, a butt joint surface is provided on one side of the wall panel 100, a construction groove is provided on the butt joint surface which is recessed inwards, the butt joint surfaces of the two wall panels 100 are butt jointed with each other, the construction grooves on the two wall panels 100 are interconnected to form a plurality of construction holes 110; adjacent construction holes 110 are interlocked with each other, and the interlocking portions form an interlocking section on the side walls of the construction groove, and the two wall panels 100 are fixed to each other via a connecting structure.

[0025] The recyclable interlocking pile prefabricated guide wall structure provided above can form a plurality of interlocking construction holes 110 by hoisting two wall panels 100 respectively on the pre-excavated guide wall grooves, butting the butt surfaces of the two wall panels 100, and fixing the two wall panels 100 to each other through a connecting structure. Then, the interlocking piles are constructed through the construction holes 110. In this way, the amount of concrete used is greatly reduced. The wall panels 100 can be disassembled and recycled, which greatly saves costs. Compared with the interlocking pile construction after the cast-in-place guide wall is completed, the construction period is greatly shortened.

[0026] The connection structure includes a connection rod 200, one end of which is detachably connected to the bite section of one wall plate 100, and the other end of which is detachably connected to the bite section of another wall plate 100. In this way, the two wall plates 100 are fixed to each other through the function of the connection rod 200.

[0027] Specifically, during the construction process, except for the engaging segments on both sides of the construction hole 110 being constructed, the remaining engaging segments all need to be placed with the connecting rods 200 .

[0028] As a preferred embodiment, the two ends of the connecting rod 200 are detachably connected to two oppositely arranged engaging sections, so that the overall structure is more stable.

[0029] Specifically, the connection structure includes a fixed steel plate 300 arranged on the bite section, and two fixed steel plates 300 are arranged on one bite section at an interval to form an installation interval, and the end of the connecting rod 200 is detachably connected to the installation interval. In this way, the end of the connecting rod 200 can be fixedly connected to the bite section by being fixedly connected to the fixed steel plate 300.

[0030] The connection structure includes a bolt 310, a fixing hole penetrating vertically is provided on the fixing steel plate 300, the fixing holes on the two fixing steel plates 300 arranged vertically and spaced apart are aligned, and a mounting hole 210 penetrating vertically is provided on the end of the connecting rod 200, and the bolt 310 passes through the fixing hole and the mounting hole 210, so that the end of the connecting rod 200 is fixedly connected in the mounting interval. In this way, the connecting rod 200 is connected to the bite section or removed from the connecting section through the fixing steel plate 300 and the bolt 310.

[0031] Specific construction operations:

[0032] Step 1: Measure and locate according to the design drawing of the interlocking pile. After the positioning is completed, dig a guide wall groove, place the wall board 100 in the groove, and wait for the two sections of the wall board 100 to fit together.

[0033] Step 2: Place the connecting rod 200 between the two fixed steel plates 300 through the construction hole (except for the bite sections on both sides of the construction hole to be constructed, the remaining bite sections need to be placed in the connecting rod 300), and then insert the pin 310 to start the bite pile construction.

[0034] Step 3: After the construction of a single bite pile is completed, remove the pin 310 and the connecting rod 200, and repeat step 2 until all the bite piles of this prefabricated guide wall section are completed. Then the wall plate 100 can be dismantled and recycled.

[0035] As a preferred embodiment, the fixing steel plate 300 is fixedly arranged on the bite section. In this way, during installation, it is only necessary to connect the fixing steel plate 300 with the connecting rod 200, and it is not necessary to install the fixing steel plate 300 separately.

[0036] Specifically, the installation groove 101 passes through the docking surface from top to bottom, so as to form a construction hole 110 for equipment construction.

[0037] A plurality of hanging ears 120 are provided on the periphery of the wall plate 100 for facilitating the hoisting of the wall plate 100. In this way, it is convenient for the equipment to hoist the wall plate 100 onto the pre-excavated guide wall groove.

[0038] The occlusal section is provided with an installation groove 101 which is formed by being recessed inward away from the construction hole 110, and the installation groove 101 has a groove opening arranged toward the construction hole 110; a fixing plate is installed in the installation groove 101, the inner end of the fixing plate is fixedly connected to the bottom of the installation groove 101, and the outer end of the fixing plate is located inside the groove opening or arranged flush with the groove opening. In this way, the design of the fixing plate is prevented from affecting the equipment construction occlusal pile, that is, the arrangement position of the fixing plate is located outside the construction hole 110.

[0039] In this embodiment, the length of the wall panel 100 is 6.0 m, the thickness of the wall panel 100 is 300 mm, and the interval between the fixed steel plates 300 arranged in an upper and lower interval in one bite section is 60 mm.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
