BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the following briefly introduces the drawings required for describing the embodiments.

[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings of the utility model to clearly and completely describe the technical solution of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 As shown, this embodiment provides a winding type cast-in-place pile concrete loss prevention sleeve, which is sleeved on the pile body and fixed by fasteners or ropes, including an inner sleeve 1, a first base fabric layer 2, a winding layer 3, a second base fabric layer 4, and a coating layer 5 arranged in sequence from the inside to the outside.

[0016] In this embodiment, the inner sleeve 1 is a cylindrical inner sleeve made of high-strength, corrosion-resistant PVC material by high-frequency heat sealing using a heat sealing machine.

[0017] In this embodiment, the first base fabric layer 2 is a sleeve-like structure sewn by sewing equipment, and is sleeved on the PVC inner sleeve 1 for shaping and protecting the inner sleeve.

[0018] In this embodiment, the winding layer 3 is made of polyester industrial filament, and is circumferentially wound on the first base fabric layer 2 in a spiral winding manner using a winding device, so as to enhance the circumferential strength of the anti-loss sleeve.

[0019] In this embodiment, the coating layer 5 is a base fabric layer with coating sprayed on the surface.

[0020] The length and diameter of the anti-loss sleeve can be customized according to the specific project needs to accommodate bored piles of different diameters and depths.

[0021] The processing flow of the above structure is as follows:

[0022] Step 1: Design and calculate the required size and specifications of the anti-loss sleeve based on the diameter and length of the bored pile.

[0023] Step 2: Cut and pre-process the selected materials according to the designed size to ensure that the quality and performance of the materials meet the requirements.

[0024] Step 3: The cut and pre-treated PVC material is made into a PVC inner sleeve through a heat sealing machine and fixed on the winding machine;

[0025] Step 4: Sew the base fabric into a tube shape through sewing equipment, and put the base fabric layer onto the PVC inner sleeve;

[0026] Step 5: Use special winding equipment to tightly fit the materials processed in the third and fourth steps in a spiral and winding manner with polyester industrial filament bundles. Place the polyester industrial filaments on the yarn platform, gather the polyester industrial filaments into bundles through the yarn plate, and then wind them. Spray adhesive while winding. Ensure that the winding is tight and uniform during the winding process.

[0027] Step 6: Repeat the processing method in step 4, and put the processed base fabric layer on the outside of the winding layer to fix and protect the winding layer;

[0028] Step 7: Spray the paint mixed in a certain proportion on the outer base fabric layer. After the paint solidifies, a colloid layer will form on the surface of the base fabric, which plays a role in wear resistance and protection.

[0029] Step 8: Carry out quality inspection on the wound anti-loss sleeve, including size measurement, strength test, corrosion resistance test, etc., to ensure that the quality of the anti-loss sleeve meets the standards.

[0030] The anti-loss sleeve of this embodiment is made of high-strength, corrosion-resistant PVC, base cloth and polyester industrial filament and other materials, and has good flexibility and wear resistance. It can not only fit tightly to the pile body, but also effectively prevent concrete loss. It plays a good protective role in the construction process of bored piles and can adapt to various environments and conditions during the construction process of bored piles.
