Description

TECHNICAL FIELD

[0001] The utility model relates to a sleeve valve pipe protection technical field, specifically to a sleeve valve pipe assembly protection device. BACKGROUND

[0002] The sleeve valve pipe is also called a flower pipe, which is a construction method in building construction. A steel sleeve valve pipe with holes is punched into or drilled into the soil, and then slurry is injected into the flower pipe by pressure. The slurry is poured into the soil layer from the hole, and then the flower pipe is lifted or sunk continuously while injecting slurry, forming reinforced soil in the soil and improving the strength of the foundation.

[0003] In the prior art, a sleeve valve pipe assembly protection device with publication number "CN204551479U" is provided on the outer wall of the sleeve valve pipe assembly. During the installation of the sleeve valve pipe assembly, the rubber band can be prevented from being scratched, and the device can also assist in guiding to ensure that the sleeve valve pipe assembly is installed vertically.

[0004] However, the above technical solution and the prior art have the following defects:

[0005] Firstly, the rubber band in the device only wraps around the annular side of the sleeve valve pipe assembly. Since there is no corresponding limiting structure to block it, the rubber band is prone to upward and downward deviation during use. Once the rubber band deviates upward and downward, it cannot effectively block the slurry outlet hole. Although the protection ring in the device can prevent the rubber band from being scratched, the protection ring will continuously contact and rub against the soil during the drilling and insertion of the sleeve valve pipe assembly into the soil. Since the outer surface of the protection ring does not have a corresponding wear-resistant structure, the protection ring is prone to wear during use. The outer diameter of the worn protection ring is smaller, which cannot protect the rubber band. Therefore, the user needs to replace the entire sleeve valve pipe assembly with a worn protection ring, which is not practical. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0027] Please refer to Figures 1-6 The utility model provides a technical scheme:

[0028] Embodiment one:

[0029] A sleeve valve pipe assembly protection device, comprising a sleeve valve pipe body 1, a rubber sleeve 2 and a grouting hole 4, a plurality of grouting holes 4 are symmetrically arranged on the left and right sides and the front and back of the annular side of the sleeve valve pipe body 1, the plurality of grouting holes 4 are of the same specification, the diameter of the grouting hole 4 is 8mm, and the upper and lower intervals of the plurality of grouting holes 4 are 35cm. The plurality of grouting holes 4 with a diameter of 8mm and an upper and lower interval of 35cm facilitate the outward discharge of grouting liquid inside the sleeve valve pipe body 1. A plurality of rubber sleeves 2 are sleeved on the annular side of the sleeve valve pipe body 1. The rubber sleeve 2 is made of ethylene propylene rubber. The rubber sleeve 2 made of ethylene propylene rubber is not only resistant to oxidation and has a long service life, but also has a certain elasticity, which can ensure that when high-pressure grouting is carried out in the sleeve valve pipe body 1, high-pressure grouting liquid passes through the grouting hole 4 and penetrates the rubber sleeve 2 under pressure to enter the surrounding stratum, and when grouting is stopped, the rubber sleeve 2 can rebound and tightly wrap the sleeve valve pipe body 1, preventing grouting liquid outside the pipe from entering the pipe, thereby serving as a check valve.

[0030] The bottom of the sleeve valve pipe body 1 is fixedly connected with an external thread connector 13, the external thread connector 13 and the sleeve valve pipe body 1 are of an integral structure, the external thread connector 13 and the sleeve valve pipe body 1 are of the same material, a connecting internal thread cavity 12 is formed on the upper end surface of the sleeve valve pipe body 1, and the connecting internal thread cavity 12 is matched with the external thread connector 13. The matched connecting internal thread cavity 12 and external thread connector 13 facilitate the assembly and connection of a plurality of sleeve valve pipe bodies 1. A sealing ring 11 is placed in the connecting internal thread cavity 12, and the sealing ring 11 is made of fluororubber. The sealing ring 11 made of fluororubber makes the sealing between the external thread connector 13 and the connecting internal thread cavity 12 better, preventing high-pressure grouting liquid inside the sleeve valve pipe body 1 from easily leaking through the connection between the external thread connector 13. A protection assembly 3 is arranged on the outer surface of the sleeve valve pipe body 1, and the protection assembly 3 is used for limiting and protecting the rubber sleeve 2, preventing the rubber sleeve 2 from deviating during use.

[0031] Example two:

[0032] On the basis of example one, in this embodiment, a plurality of first blocking blocks 31 and second blocking blocks 33 are fixedly connected to the annular side of the sleeve valve pipe body 1, which can block and limit the rubber sleeve 2 sleeved on the annular side of the sleeve valve pipe body 1, preventing the rubber sleeve 2 from deviating upward and downward during use, thereby ensuring the stability of the rubber sleeve 2. Spraying a wear-resistant coating 36 on the outer surface of the protection ring 32 can improve the wear resistance of the outer surface of the protection ring 32, thereby prolonging the service life of the protection ring 32.

[0033] The protection assembly 3 comprises a first blocking block 31 and a protection ring 32, a plurality of first blocking blocks 31 are symmetrically and fixedly connected to the left and right sides and the front and back sides of the annular side of the sleeve valve pipe body 1, and the first blocking block 31 is located at the upper end of the rubber sleeve 2. The material of the first blocking block 31 is the same as that of the sleeve valve pipe body 1, and the first blocking block 31 and the sleeve valve pipe body 1 are of an integral structure. The first blocking block 31 can block and limit the upper end of the rubber sleeve 2, so as to avoid the rubber sleeve 2 sleeved on the annular side of the sleeve valve pipe body 1 from being upwardly deviated during use. A plurality of protection rings 32 are fixedly connected to the annular side of the sleeve valve pipe body 1, and the protection ring 32 is located below the rubber sleeve 2. The protection ring 32 has a semicircular cross-sectional shape. The semicircular cross-sectional shape of the protection ring 32 makes the sleeve valve pipe body 1 more smoothly descend in the soil. The protection ring 32 has an outer diameter larger than that of the rubber sleeve 2. The material of the protection ring 32 is the same as that of the sleeve valve pipe body 1, and the protection ring 32 and the sleeve valve pipe body 1 are of an integral structure. The protection ring 32 having an outer diameter larger than that of the rubber sleeve 2 can protect the rubber sleeve 2, so as to avoid the rubber sleeve 2 from being directly rubbed and contacted with the soil during the descending of the sleeve valve pipe body 1 in the soil, thereby accelerating the abrasion of the rubber sleeve 2.

[0034] A plurality of second blocking blocks 33 are fixedly connected to the annular side of the sleeve valve pipe body 1, and the second blocking block 33 is located at the lower end of the rubber sleeve 2. The first blocking block 31 and the second blocking block 33 are the same in number and specification. The material of the second blocking block 33 is the same as that of the sleeve valve pipe body 1, and the second blocking block 33 and the sleeve valve pipe body 1 are of an integral structure. The second blocking block 33 can block and limit the lower end of the rubber sleeve 2, so as to avoid the rubber sleeve 2 sleeved on the annular side of the sleeve valve pipe body 1 from being downwardly deviated during use. The first blocking block 31 and the second blocking block 33 are both right trapezoids. The first blocking block 31 and the second blocking block 33 which are both right trapezoids can more smoothly be sleeved on the annular side of the sleeve valve pipe body 1 at a specified position downwardly or upwardly during installation of the rubber sleeve 2.

[0035] The upper end surface of the protection ring 32 is fixedly connected with a plurality of first reinforcing pieces 34, the lower end surface of the protection ring 32 is fixedly connected with a plurality of second reinforcing pieces 35, the first reinforcing pieces 34 and the second reinforcing pieces 35 are integrated with the protection ring 32 and the sleeve valve pipe body 1, the materials of the first reinforcing pieces 34 and the second reinforcing pieces 35 are the same as the material of the sleeve valve pipe body 1, the shapes of the first reinforcing pieces 34 and the second reinforcing pieces 35 are right-angled triangles, the right-angled triangular first reinforcing pieces 34 and the second reinforcing pieces 35 can further improve the connection stability between the protection ring 32 and the sleeve valve pipe body 1, the outer surface of the protection ring 32 is sprayed with a wear-resistant coating 36, and the material of the wear-resistant coating 36 is high-temperature wear-resistant paint, the wear-resistant coating 36 mainly consists of high-temperature wear-resistant aggregate, ultra-fine powder and inorganic polymer dispersion liquid, the particles of the wear-resistant coating are tightly packed after curing, there is no large macroscopic defect, the volume density is large, the strength at room temperature can reach more than 180Mpa, and the wear-resistant ability of the outer surface of the protection ring 32 is improved.

[0036] Working principle: by fixedly connecting a plurality of first blocking pieces 31 and second blocking pieces 33 on the annular side surface of the sleeve valve pipe body 1, the rubber sleeve 2 sleeved on the annular side surface of the sleeve valve pipe body 1 can be blocked and limited, so that the rubber sleeve 2 is prevented from being offset up and down during use, and the first blocking pieces 31 and the second blocking pieces 33 in the shape of right-angled trapezoids also facilitate the rubber sleeve 2 to be more smoothly sleeved downward or upward on the annular side surface of the sleeve valve pipe body 1 at the specified position; by fixedly connecting a plurality of protection rings 32 with an outer diameter larger than that of the rubber sleeve 2 on the annular side surface of the sleeve valve pipe body 1, the outer diameter of the sleeve valve pipe body can be further increased, so that the rubber sleeve 2 is prevented from being directly rubbed and contacted with the land to accelerate wear when the sleeve valve pipe body 1 is inserted into the land and the rubber sleeve 2 moves downward with the sleeve valve pipe body 1, the service life of the rubber sleeve 2 is prolonged, the wear-resistant coating 36 sprayed on the outer surface of the protection ring 32 can improve the wear-resistant ability of the outer surface of the protection ring 32, so as to prolong the service life of the protection ring 32, and the fixedly connected first reinforcing pieces 34 and second reinforcing pieces 35 can further improve the connection stability between the protection ring 32 and the sleeve valve pipe body 1.
