Description

Technical Field

[0001] The present invention relates to the technical field of road installation structures, and particularly to a buried part of a sound barrier foundation structure and a construction method thereof. Background Art

[0002] With the acceleration of the urbanization process and the increasing improvement of the transportation network, the problem of traffic noise pollution has become increasingly serious. As an effective noise control means, sound barriers have been widely used in traffic noise control projects such as urban expressways, highways, railways or rail transit. The buried parts of sound barriers, as important structural components connecting the steel columns of sound barriers and the lower foundation structure, need to withstand the wind loads once in 50 years or even 100 years in the local area during use. Attention should be paid to their structural design and construction to ensure that the steel columns of sound barriers and the lower foundation structure are firmly fixed to meet the requirements of structural safety. Most of the existing buried parts of sound barriers are in two structural forms. One is composed of an anchor plate and symmetrically arranged straight anchor bars. The steel columns of sound barriers are often welded to it. This method has complex technology, inconvenient construction, low construction efficiency, and the on-site welding quality is not easy to control by humans, with poor stability. The other is composed of a group of exposed column base anchor bolts. The existing reinforced concrete structure construction manual requires that the distance from the center of the column base anchor bolts to the edge of the concrete should not be less than 5d (d is the diameter of the column base anchor bolts), and should not be less than 150 mm. Therefore, this buried part method is limited in application due to the insufficient width of the bridge section crash barrier or guardrail plate, affecting the setting and application or overall stability of the sound barrier. Summary of the Invention

[0003] Therefore, in order to solve the above deficiencies, the present invention provides a buried part of a sound barrier foundation structure and a construction method thereof here.

[0004] The present invention is implemented as follows. A buried part of a sound barrier foundation structure and a construction method thereof are constructed. The device includes an anchor plate; a grouting hole penetrates through the middle area of the anchor plate, holes penetrate through the two end areas of the anchor plate, bolts on the anchor plate pass through the holes and are fixed to the anchor plate by buckles, and multiple groups of straight anchor bars are fixedly connected to one end of the anchor plate away from the bolts.

[0005] In a feasible implementation manner, the straight anchor bars and the anchor plate are fixed by T-shaped welding.

[0006] In a feasible implementation manner, a cavity is provided inside the anchor plate, and the cavity is communicated with the grouting hole.

[0007] In a feasible implementation manner, an extrusion film is fixedly connected to the connection between the grouting hole and the connection between the grouting hole and the hole, and the cavity is filled with water-absorbing and swelling rubber particles.

[0008] In a feasible implementation manner, a water-absorbing cotton strip is wound inside the cavity, and the water-absorbing cotton strip extends outward through the side wall of the anchor plate.

[0009] In a feasible implementation manner, a contact component is provided on the anchor plate. The contact component includes an outer ring, the outer ring is embedded and fixedly connected to the anchor plate, a check valve is embedded on the side wall of the outer ring, a spring is fixedly connected to the inner bottom of the outer ring, and the top of the spring is fixedly connected to the inner ring; the inner ring is slidably connected inside the outer ring, a delivery pipe is embedded at the lower end of the outer ring, the other end of the delivery pipe is communicated with the inside of the inner rod, an arc-shaped groove is embedded on the side wall of the inner rod, a contact rod is slidably inserted into the arc-shaped groove, the contact rod is fixedly connected inside the outer rod, and the outer rod is slidably connected to the inner rod; a check valve is embedded at the top of the outer rod, and a closing element in the check valve is fixedly connected to the contact rod; multiple groups of convex rods are fixedly connected to the side wall of the outer rod.

[0010] A construction method for the embedded part of the sound barrier foundation structure includes the following steps;

[0011] S1: First, make holes in the anchor plate, and after the bolts pass through the anchor plate, fix them on the anchor plate using buckles;

[0012] S2: At the same time, the straight anchor bars and the anchor plate are fixed by T-shaped welding, and then determine the embedded position of the embedded part in the lower foundation structure and firmly fix it.

[0013] The present invention has the following advantages: The present invention provides an embedded part of the sound barrier foundation structure and its construction method through improvement. Compared with the same type of equipment, the following improvements are made:

[0014] For the embedded part of the sound barrier foundation structure and its construction method of the present invention, since the embedded bolts are pre-positioned by drilling holes in the factory, the positioning of the embedded bolts is accurate, there is no need for on-site welding, and it can be used for all road sound barriers, adapting to different installation environments, improving the flexibility and adaptability of installation.

[0015] For the embedded part of the sound barrier foundation structure and its construction method of the present invention, the embedded bolts are accurately positioned, the construction is fast and convenient, and it can be used for all road sound barriers.

[0016] For the embedded part of the sound barrier foundation structure and its construction method of the present invention, when the sound barrier column is installed, the inner ring is pressed to push the glue into the inner rod through the delivery pipe, and finally injected into the cylindrical through hole of the sound barrier through the check valve at the top of the outer rod; this process realizes the automatic filling and sealing of the glue. The convex rods of the outer rod are slidably matched with the arc-shaped grooves in the cylindrical through hole of the sound barrier to form a spiral self-rotating insertion mechanism, increasing the contact area and region between the anchor plate and the sound barrier; the contact component realizes the integrated operation of "installation and sealing" through structural linkage, reducing the manual glue injection step, reducing the construction difficulty and man-hour cost, and at the same time avoiding problems such as glue leakage or uneven glue injection.

Specific embodiments

[0023] The following will be combined with the attached Figures 1 - 5 The present invention will be described in detail. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1;

[0025] Please refer to Figures 1 to 5 , a buried part of a sound barrier foundation structure and its construction method of the present invention, including an anchor plate 1. A grouting hole 2 runs through the middle area of the anchor plate 1. Holes 11 run through both end areas of the anchor plate 1. A bolt 3 on the anchor plate 1 passes through the hole 11 and is fixed to the anchor plate 1 through a buckle 4. The buckle 4 is spot - welded to the anchor plate 1 to prevent the bolt from rotating. One end of the anchor plate 1 away from the bolt 3 is fixedly connected with multiple groups of straight anchor bars 5; the diameter of the hole 11 is 1 - 1.5 mm larger than the diameter of the bolt 3; the special buckle is equivalent to an inner wrench to prevent the bolt from rotating and not being tightened when fixed.

[0026] Specifically, a cavity 12 is provided inside the anchor plate 1. The cavity 12 is in communication with the grouting hole 2. And an extrusion film 13 is fixedly connected at the connection between the grouting hole 2 and the grouting hole 2 and the hole 11. The cavity 12 is filled with water - absorbing and swelling rubber particles.

[0027] Specifically, a water - absorbing cotton strip is wound inside the cavity 12, and the water - absorbing cotton strip extends outward through the side wall of the anchor plate 1.

[0028] Specifically, the straight anchor bar 5 and the anchor plate 1 are fixed by T-shaped welding.

[0029] Specifically, the anchor plate 1 is first drilled to form a cavity 12, a hole 11 and a grouting hole 2. After the bolt 3 passes through the anchor plate 1, it is fixed to the anchor plate 1 by a buckle 4. At the same time, the straight anchor bar 5 and the anchor plate 1 are fixed by T-shaped welding. Then, the embedding position of the embedded part in the lower foundation structure is determined and firmly fixed. Finally, the lower foundation structure concrete is poured through the grouting hole 2 reserved on the anchor plate 1 to ensure the reliable connection of the embedded part and improve the overall stability of the sound barrier. After the concrete pouring is completed, the absorbent cotton strip at the bottom of the anchor plate 1 absorbs the moisture of the concrete and transmits it upward into the cavity 12 and is absorbed by the water-absorbing and expanding rubber particles. The water-absorbing and expanding rubber particles expand as a whole, and then push the extrusion film 13 in the area of the grouting hole 2 and the extrusion film 13, so that the extrusion film 13 blocks and seals the grouting hole 2. Then, the extrusion film 13 passes through the hole 11 and contacts the side wall of the bolt 3, enhancing the connection stability and sealing effect between the anchor plate and the bolt.

[0030] Specifically, the load borne by the sound barrier is transmitted to the anchor plate 1 through the bolt 3, and the anchor plate 1 transmits the force to the straight anchor bar 5. Finally, the force is transmitted to the lower foundation structure through the straight anchor bar 5. This structural design can effectively transmit the load, ensure the safe and reliable force-bearing of the embedded part, have sufficient bearing capacity and durability, and can meet the requirements of long-term use.

[0031] Embodiment Two;

[0032] Please refer to Figures 1~5 , for a sound barrier foundation structure embedded part and its construction method of the present invention, compared with Embodiment One, this embodiment further includes;

[0033] A contact component 6 is provided on the anchor plate 1. The contact component 6 includes an outer ring 61, and the outer ring 61 is embedded and fixedly connected to the anchor plate 1. A one-way valve is embedded on the side wall of the outer ring 61, and glue can be filled into the inside through the one-way valve. A spring 62 is fixedly connected to the inner bottom of the outer ring 61, and the top of the spring 62 is fixedly connected to the inner ring 63. The inner ring 63 is slidably connected inside the outer ring 61. A delivery pipe 64 is embedded at the lower end of the outer ring 61, and the other end of the delivery pipe 64 is communicated with the inside of the inner rod 65. An arc-shaped groove 66 is embedded on the side wall of the inner rod 65, and a contact rod is slidably inserted into the arc-shaped groove 66. The contact rod is fixedly connected to the outer rod 67, and the outer rod 67 is slidably connected to the inner rod 65.

[0034] A one-way valve 69 is embedded at the top of the outer rod 67, and the closing element in the one-way valve 69 is fixedly connected to the contact rod 610; an arc-shaped groove 66 is embedded on the inner side surface of a cylindrical through hole provided in the contact area between the sound barrier column and the anchor plate 1; multiple groups of convex rods 68 are fixedly connected to the side wall of the outer rod 67.

[0035] After the installation of the sound barrier column, when the sound barrier column contacts the anchor plate 1, the sound barrier column applies a thrust to the inner ring 63, and the inner ring 63 moves inward. The inner ring 63 squeezes the glue inside the outer ring 61 into the delivery pipe 64, and then transports it through the delivery pipe 64 into the inner rod 65, and pushes the outer rod 67 to move upward and rotate. The outer rod 67 is inserted into the cylindrical through hole in the anchor plate, and the convex rod 68 slides in the arc-shaped groove 66 in the cylindrical through hole. Subsequently, the contact rod 610 contacts the top of the cylindrical through hole, and the contact rod 610 pushes open the one-way valve 69, so that the glue inside is transported to the contact area between the outer rod 67 and the cylindrical through hole in the anchor plate.
