Description

Technical Field

[0001] This invention relates to the field of steel sheet pile construction in weir sections, and more specifically, to a steel sheet pile tie rod installation platform and its installation method for weir sections. Background Technology

[0002] During the construction of the steel sheet pile section of the weir, the inner and outer steel sheet piles need to be fixed by connecting them with steel walers and steel tie rods. The tie rods pass through the outer and inner steel sheet piles respectively, and their ends are connected and fixed by steel walers. Since the construction site is on the sea, the existing tie rods are usually inserted through the through holes in the outer steel sheet piles and then aligned with the through holes in the inner steel sheet piles. However, due to the relatively long length and heavy weight of the tie rods, the installation is very difficult and the alignment of the tie rods with the through holes in the inner steel sheet piles is also difficult, resulting in low installation efficiency of the tie rods, which needs further improvement. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a steel sheet pile tie rod installation platform for weir construction sections, which has the advantage of improving tie rod installation efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A steel sheet pile tie rod installation platform for a weir section includes a platform body placed between outer steel sheet piles and inner steel sheet piles. Hanging rods are provided on both sides of the platform body. A horizontally arranged sliding beam is fixed to the top of the hanging rod and supported on the installed tie rod. The two ends of the hanging rod are detachably connected to the sliding beam and the platform body, respectively. An extension is provided on one side of the platform body along the construction direction.

[0006] The platform body is placed between the outer and inner sheet piles, and is connected to the pre-installed tie rods via a sliding beam. At this point, workers can stand on the platform body to install new tie rods at the extension. Even if the sea level drops, it will not affect the normal use of the platform body. The sliding beam can slide horizontally on the tie rods, allowing multiple tie rods to be installed as the platform body moves forward. This effectively reduces the difficulty of installing tie rods at sea level, making the installation operation convenient and labor-saving, and effectively improving the installation efficiency of tie rods. If a boom is blocked by a tie rod, the boom can be removed and reinstalled later.

[0007] The present invention further includes the following feature: pontoons are uniformly fixed to the bottom of the platform body.

[0008] The use of pontoons increases the buoyancy of the platform, allowing it to float on the sea surface. This facilitates the platform's movement to pre-installed tie rods during installation and makes it easier to transport the platform.

[0009] The present invention further includes a hand-operated hoist on the side of the extension away from the platform body, and one end of the hand-operated hoist is fixed to the sliding beam.

[0010] By using a hand chain hoist, after the extension rod is installed, one end of the hoist can be fixed to the newly installed rod. Then, by pulling the chain hoist, the sliding beam and platform body can be moved forward, allowing the platform body to move continuously to complete the installation of subsequent rods. This also makes the operation of moving the platform body easier and less strenuous.

[0011] The present invention further provides that the width of the extension is greater than the distance between adjacent tie rods.

[0012] This ensures that the next tie rod is installed within the extension, making it easier for workers to install it on the platform itself.

[0013] The present invention further includes: protrusions spaced apart on both sides of the platform body; corresponding mounting holes for installing the hanger rods are provided on the protrusions and the sliding beam; and the hanger rods are fixed to the sliding beams and protrusions by bolts and nuts.

[0014] The mounting holes on the protrusions facilitate the subsequent installation and fixing of the lifting rods. Furthermore, these mounting holes can also be used as lifting holes when the platform body is lifted by a ship crane, thus achieving the multi-purpose use of the mounting holes.

[0015] The present invention further comprises: the hand-operated hoist being symmetrically arranged on both sides of the extension.

[0016] Two hand chain hoists are symmetrically arranged, so that when the platform body is moved, both hand chain hoists can be pulled simultaneously, so that the platform body can move more stably and in a balanced manner with forces on both sides at the same time, avoiding the situation where the platform body will collide with the steel sheet pile due to forces on one side.

[0017] The present invention further specifies that the width of the platform body is less than the distance between the outer steel sheet pile and the inner steel sheet pile.

[0018] This maintains a certain distance between the platform body and both the outer and inner sheet piles, facilitating subsequent horizontal movement of the platform body and reducing the possibility of the platform body colliding with the sheet piles.

[0019] The present invention further provides that: the bottom of the platform body is provided with spacers at intervals, and adjacent spacers form a spacer groove, the width of the spacer groove is the same as that of the pontoon, and the pontoon is installed in the spacer groove.

[0020] By installing the pontoon in a spacer slot of the same width, the spacer bars can provide horizontal obstruction to the pontoon, thereby improving the stability of the pontoon installation.

[0021] Another objective of this invention is to provide an installation method for a steel sheet pile tie rod installation platform for a weir section, which has the advantages of simple structure and easy installation.

[0022] To achieve this objective, the present invention provides the following technical solution:

[0023] An installation method for a steel sheet pile tie rod installation platform in a weir section includes the following steps:

[0024] Step 1: Fix the pontoon to the bottom of the platform body, and pre-install at least 2 tie rods between the outer steel sheet piles and the inner steel sheet piles;

[0025] Step 2: Transport the platform body to the area between the outer and inner steel sheet piles by ship, and use a ship crane to lift the platform body and place it on the sea surface;

[0026] Step 3: Loosen the lifting device on one side of the ship crane and push the platform body to float below the pre-installed tie rod;

[0027] Step 4: Re-secure the hoisting parts that were detached in Step 3, lift the platform body with the help of the ship crane, place the sliding beam on the tie rod and fix the sliding beam and the platform body together with the hoisting rod;

[0028] Step 5: Unscrew the cranes from both sides of the platform body;

[0029] Step 6: Install the hand chain hoist at the end of the sliding beam facing the construction direction.

[0030] This method allows the platform body to be smoothly installed between the outer and inner sheet piles, making the installation process convenient and quick.

[0031] The present invention further includes the following configuration: after the platform body is lifted in step 4, the tie rod abuts against the side of the lifting rod facing away from the construction direction.

[0032] This arrangement ensures that the tie rod abuts against the side of the boom facing away from the construction direction during platform installation. Consequently, when moving the platform body later, the boom of the platform body can maintain maximum travel range before being obstructed by the tie rod, effectively improving the efficiency of subsequent platform body movement.

[0033] In summary, the present invention has the following beneficial effects:

[0034] The platform's design allows workers to stand stably on it during tie rod installation, unaffected by sea level drops. This makes tie rod installation at sea more convenient, saving time and effort and significantly improving installation efficiency. The platform can be pulled forward using hand-operated hoists on both sides, ensuring balanced force distribution and better stability, preventing collisions with outer or inner sheet piles. Furthermore, the presence of buoyancy boxes at the bottom of the platform provides buoyancy, allowing it to float on the sea surface during installation and facilitating its transport.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] A steel sheet pile tie rod installation platform for a weir section, such as Figure 1 and Figure 2As shown, the platform body 3 is placed between the outer sheet piles 1 and the inner sheet piles 2. Multiple protrusions 4 are fixed at intervals along the length of both sides of the platform body 3, and mounting holes 5 are provided on the protrusions 4. A hanger rod 8 is fixedly installed on each protrusion 4. One end of the hanger rod 8 is provided with a bolt 6 passing through the mounting hole 5, and the end is tightened with a nut 7 to secure it to the protrusion 4. The other end is provided with a sliding beam 9 mounted on a pre-installed tie rod 16. This end of the hanger rod 8 is also fixed to the sliding beam 9 with bolts 6 and nuts 7. This allows for a detachable connection between the hanger rod 8, the protrusions 4, and the sliding beam 9. The hanger rods 8 are connected to the spaced protrusions 4. Furthermore, an extension 10 is provided on the platform body 3 along the construction direction. The length of the extension 10 is greater than the distance between adjacent tie rods 16. When operating at sea, with the help of the platform body 3, the tie rod 16 is installed on the extension 10. Workers can install the tie rod 16 on the platform body 3. After each new tie rod 16 is installed, the platform body 3 can be moved along the construction direction. If the suspender 8 is blocked by the tie rod 16 and cannot move forward, the blocked suspender 8 can be removed. At this time, the platform body 3 and the sliding beam 9 are connected and fixed through the unblocked suspender 8. After the platform body 3 is moved, the suspender 8 can be reinstalled. This cycle can be repeated to complete the installation of all tie rods 16 on the steel sheet piles of the weir section. Moreover, even if the sea level drops, it will not affect the use of the platform body 3, thus facilitating the installation of tie rods 16 at sea and greatly improving the installation efficiency of tie rods 16.

[0040] Because the platform body 3 is relatively heavy, in order to facilitate the sliding beam 9 to slide on the tie rod 16, a hand chain hoist 11 is provided on the side of the extension 10 away from the platform body 3. One end of the hand chain hoist 11 is fixed to the sliding beam 9. After the tie rod 16 at the extension 10 is completed, the other end of the hand chain hoist 11 can be fixed to the newly installed tie rod 16. Then, the hand chain hoist 12 on the hand chain hoist 11 is pulled, making the operation of moving the platform body 3 easier and less strenuous. Moreover, there are two hand chain hoists 11 symmetrically arranged. During the pulling process, the two hand chain hoists 11 can be pulled simultaneously, so as to keep the platform body 3 evenly stressed on both sides, making the movement more stable and avoiding collisions with the outer steel sheet pile 1 or the inner steel sheet pile 2. In addition, the width of the platform body 3 is slightly smaller than the distance between the outer steel sheet pile 1 and the inner steel sheet pile 2. This can keep the platform body 3 from coming into contact with the outer steel sheet pile 1 or the inner steel sheet pile 2 when it moves, reducing the probability of collision.

[0041] In addition, pontoons 13 are fixed to the bottom of the platform body 3 at intervals. The pontoons 13 enable the platform body 3 to float on the sea surface, which facilitates the movement of the platform body 3 on the sea surface during the initial installation process and provides convenience for the transfer of the platform body 3. In order to further improve the installation stability of the pontoons 13, spacers 14 are set at intervals on the bottom of the platform body 3, and spacer grooves 15 are formed between adjacent spacers 14. The width of the pontoons 13 is the same as the width of the spacer grooves 15, and the pontoons 13 are installed and fixed in the spacer grooves 15. This makes it less likely for the pontoons 13 to shift in the horizontal direction, and the installation stability is more guaranteed.

[0042] Specific installation and usage process: First, fix each pontoon 13 in the spacer slot 15 of the platform body 3. Then, install three tie rods 16 between the outer sheet piles 1 and the inner sheet piles 2. Use a ship to transport the platform body 3 to the construction site of the sheet piles in the embankment section. Use a ship crane to lift it and place it between the outer sheet piles 1 and the inner sheet piles 2, with the lifting position on both sides of the platform body 3. After detaching one side of the platform body 3 from the hoisting, the platform body 3 floats on the sea surface. Push it to move it so that it is below the pre-installed tie rods 16. Then, detach one side of the platform body 3 and re-hoist it with the ship crane. Use the ship crane to lift it up, and then place the sliding beam 9 on the pre-installed tie rods 16. Install the lifting rod 8 to fix the sliding beam 9 to the platform body 3. At this time, keep... Hold the tie rod 16 against the side of the hoist 8 facing away from the construction direction to maintain the maximum movement of the subsequent sliding beam 9. After the platform body 3 is unloaded, the platform body 3 will not fall as it is suspended from the tie rod 16 by the sliding beam 9. Finally, install the hand-operated hoist 11 on the side of the sliding beam 9 closest to the construction direction to complete the installation of the entire platform. Workers will then install the next tie rod 16 on the extension 10 of the platform body 3. After completion, the sliding beam 9 will be moved along the construction direction by pulling the hand-operated hoist 11. When the hoist 8 is blocked by the tie rod 16, the hoist 8 will be removed and the movement will continue. After it moves past the block, the hoist 8 will be reinstalled. After each new tie rod 16 is installed, the platform body 3 will be pulled forward a certain distance until the installation of the tie rods 16 on the steel sheet piles of the entire dam section is completed.
