Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1 to 4, an embodiment of the present invention provides a square glass fiber sleeve for reinforcing an underwater pile foundation, including a sleeve main body 1, a stopper 2 and a fixing member 3; wherein the content of the first and second substances,

the cross section of the sleeve main body 1 is rectangular, the sleeve main body 1 is composed of two half sleeves 11 which are spliced with each other, splicing seams 12 of the two half sleeves 11 are arranged along the axial direction of the sleeve main body 1, and splicing plates 13 are integrally arranged on the outer sides of the edges of the half sleeves 11 at the splicing seams 12;

the plurality of stoppers 2 are uniformly distributed and fixedly arranged on the inner wall of the sleeve main body 1 and used for controlling the distance between the inner wall of the sleeve main body 1 and the outer wall of the pile foundation;

the fixing piece 3 is provided with a plurality of fixing pieces, and the fixing pieces are arranged on the splicing plates 13 at equal intervals along the axial direction of the sleeve main body 1 and used for fixing the two splicing plates 13 which are positioned on the same side of the sleeve main body 1.

In this embodiment, for the reasonable reinforcement treatment to square pile foundation under water of laminating more, design sleeve main part 1 into with the pile foundation to the rectangle section structure that matches. For the telescopic installation of glass fiber in the convenient reinforcement process, design into the form that adopts two half sleeves 11 to assemble with sleeve main part 1, and half sleeve 11 highly lower relatively, also convenient transportation. The splice joint 12 department of assembling at half sleeve 11 sets up the splice plate 13 of pterygoid lamina formula, through fixing the splice plate 13 that corresponds, has realized 11 concatenations between the half sleeve and has fixed. Compared with the original installation method that the glass fiber sleeve is firstly damaged, then the glass fiber sleeve is sleeved on the periphery of a pile foundation and finally repaired, the glass fiber sleeve is more reasonable in structural design, high in structural strength and convenient to install, the construction period is shortened, and the construction quality of the reinforced structure is ensured.

The half-sleeve 13 of the present application also employs a new process in the manufacturing process. The corner of the half sleeve 13 is not formed by bending the glass fiber cloth and the resin after the composite molding, and the bent corner is easy to break, so that the structural strength is relatively low. The half sleeve 13 of this application has adopted the mold processing, lays the fine cloth of glass according to the trend of mould on the mould, and the fine cloth of glass that has certain flexibility forms the turning earlier, then immerses resin glue on the fine cloth of glass and carries out compound solidification shaping. The half-sleeve 13 processed by the method has the same structural strength at the corner as the plane part, and the whole structural strength is higher.

Stopper 2 sets up on the inner wall of sleeve main part 1, through stopper 2's height, the thickness of epoxy grout material between control sleeve main part 1 that can be accurate and the pile foundation, and the thickness of epoxy grout material is even.

When the glass fiber sleeve of this application is consolidated the pile foundation, at first clear up the surface of pile foundation, at the inner wall bottom installation sealing strip of two half sleeves 11. Then, coating sealing glue on the inner walls of the splicing plates 13 of the two half-sleeves 11, correspondingly sleeving the two half-sleeves 11 on the pile foundation, sealing the splicing seams 12 of the two half-sleeves 11 by the sealing glue, and fixedly binding the two half-sleeves 11 by adopting a fastening belt so as to enable the stopper 2 to be completely attached to the outer wall of the pile foundation; and fixing the corresponding splicing plates 13 by using the fixing pieces 3 to connect the two half sleeves 11 into a whole. After the fine sleeve of glass is installed, mix epoxy grout material, inject epoxy grout material into the cavity between fine sleeve of glass and the pile foundation, paint the capping at fine sleeve of glass's top and glue, wait to demolish the fastening area after epoxy grout material solidifies, accomplished the reinforcement of pile foundation promptly. The construction is quick and convenient, and the construction cost is saved.

In a preferred embodiment, as shown in FIG. 3, the splice seam 13 is disposed on the centerline of the sidewall of the sleeve body 1. Namely, the splice plates 13 have the same distance from the corners, so that the four corners of the sleeve body 1 are uniformly stressed, and local damage is avoided.

In a preferred embodiment, as shown in fig. 4, the position limiter 2 is in a hemispherical shape, a cylindrical shape or a truncated cone shape, the position limiter 2 is arranged on the inner wall of the sleeve main body 1 in a rhombus distribution, and when the fastening belt binds the position limiter, the position limiter 2 has a better supporting effect, and the sleeve main body 1 is ensured not to deform.

In a preferred embodiment, the fixing member 3 is a bolt or a stainless steel nail. Bolts are adopted for fixing, threaded holes need to be formed in the splice plates 13 firstly, the threaded holes corresponding to the splice plates 13 need to be aligned during installation, the fixation is firm, but the installation is relatively troublesome; the stainless steel nails are adopted for fixing, holes do not need to be formed in the splice plates firstly, and a nail gun is adopted for directly nailing the splice plates into the fixed positions, so that the stainless steel nail is simple, convenient and quick to install, but the fixing effect is relatively poor. When the reinforcing installation is carried out, the corresponding fixing piece 3 can be selected according to actual requirements.
