DETAILED DESCRIPTION
[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0021] See also Figure 1-5 This embodiment provides a bridge deck splicing construction method, comprising the following steps: S1: Install several bridge piers in sequence on the sea surface according to the designated positions; S2: A bow bridge deck 1 is provided, and the bow bridge deck 1 is provided between the shore and the frontmost bridge pier, and the bow bridge deck 1 is connected to the shore and the frontmost bridge pier respectively; S3: A bridge deck 2 is also provided. A sliding slot is provided at one end of the head bridge deck 1 close to the bridge pier. The bridge deck 2 is provided with a sliding block 11 that matches the sliding slot. The bridge deck 2 is moved to the top of one side of the head bridge deck 1 by a crane. S4: The crane gradually lowers the height of the bridge deck 2 so that the sliding block 11 cooperates with one side of the sliding slot; S5: A sliding cylinder 3 is provided at one end of the head bridge deck 1 close to the bridge pier, and the output end of the sliding cylinder 3 is connected to the sliding block 11. The sliding cylinder 3 and the crane work together to pull the bridge deck 2 so that the sliding block 11 is fully matched with the sliding slot hole; S6: dismantle the sliding cylinder 3 and install the sliding cylinder 3 on the frontmost bridge deck 2. The end of the bridge deck 2 away from the head bridge deck 1 is provided with a sliding slot hole, and the sliding slot hole is used to cooperate with the sliding block 11 of the adjacent bridge deck 2; S7: Repeat steps S3-S6 until all the bridge panels 2 are installed on the bridge piers, disassemble the crane and the sliding cylinder 3, and complete the splicing of the bridge deck. This solution is provided with sliding slots and sliding blocks 11. First, the bridge panel 2 is lifted to the top of the sliding slot of the head bridge deck 1 by a crane, and the bridge panel 2 is lowered by a crane so that one side of the sliding block 11 of the bridge panel 2 is matched with one side of the sliding slot. Since only one side of the sliding block 11 is matched with one side of the sliding slot, such a setting not only easily ensures the matching of the sliding block 11 with the sliding slot; at the same time, since the sliding block 11 is matched with the sliding slot, the bridge panel 2 is restricted to move only along the setting direction of the sliding slot. Even if the sea breeze blows, it will not affect the matching of the sliding block 11 with the sliding slot, so that the bridge panel 2 can smoothly achieve its connection with the head bridge deck 1, and then through The sliding cylinder 3 is pulled to pull the bridge deck 2, so that the sliding block 11 and the sliding slot hole are fully matched; then, the above steps are repeated to realize the mutual connection of the two adjacent bridge decks 2, which solves the problem that the existing bridge deck splicing is to pass a fixing bolt between the two adjacent bridge decks to lock the two adjacent bridge decks to realize the connection of the two bridge decks; however, such a setting has a very high position accuracy of the two bridge decks, and there is a situation where the fixing bolts cannot be passed through the bolt holes because the bolt holes of the two adjacent bridge decks cannot be aligned; especially for bridge deck splicing at sea, due to the strong sea breeze, the bridge deck is prone to shaking during installation, making it difficult to align the bolt holes of the two bridge decks, thereby slowing down the construction speed and efficiency of bridge deck splicing.
[0022] Further, with respect to the limitation of the above-mentioned step S5, in this scheme, when looking downward from the vertical direction, when the sliding block 11 is not yet completely located in the sliding slot, the crane controls the height of the bridge deck 2 so that there is a certain distance between the sliding block 11 and the bottom surface of the sliding slot; when the sliding block 11 is completely located in the sliding slot, the crane controls the height of the bridge deck 2 to drop so that the bottom surface of the sliding block 11 is fitted with the surface of the sliding slot; such a setting is beneficial when the sliding block 11 and the sliding slot are not fully matched, in order to reduce the friction of the sliding block 11 sliding along the setting direction of the sliding slot, there is a certain distance between the bottom of the sliding block 11 and the bottom surface of the sliding slot, thereby ensuring that the sliding cylinder 3 can pull the bridge deck 2 to move.
[0023] During the sliding process of the bridge deck 2, due to the gap between the bottom surface of the bridge deck 2 and the bottom surface of the sliding slot, there is wind force from the sea breeze, causing the bridge deck 2 to swing up and down. Based on this, in order to ensure that the output end of the sliding cylinder 3 can smoothly cooperate with the bridge deck 2, the present scheme is also provided with a hinged rod 4, and the two ends of the hinged rod 4 are respectively detachably hinged to one end of the bridge deck 2 and the output end of the sliding cylinder 3, so as to ensure that even if one end of the bridge deck 2 swings up and down, the sliding cylinder 3 can still work normally to pull the suspended bridge deck 2.
[0024] Specifically, the present scheme also includes a plurality of positioning units, and the plurality of positioning units are respectively matched with a plurality of sliding slots, and any positioning unit is arranged in the corresponding sliding slot; the positioning unit includes a left baffle plate 6 unit and a right baffle plate 7, and the left baffle plate 6 unit includes a left baffle plate 6, and the left baffle plate 6 can be raised and lowered on the left side of the sliding slot, and the right baffle plate 7 is arranged on the right side of the sliding slot; the purpose of the left baffle plate 6 and the right baffle plate 7 arranged in the present scheme is that after the sliding block 11 is completed and installed in the sliding slot, the left baffle plate 6 and the right baffle plate 7 will jointly limit the movement of the sliding block 11, thereby realizing the splicing of the bridge deck 2.
[0025] In addition, in order to achieve the structural effect that the left baffle 6 of this solution can be lifted and lowered, the left baffle 6 unit of this solution also includes a lifting spring 5, the head bridge plate 1 and the bridge deck 2 are both provided with a connecting slot, the connecting slot is connected to the sliding slot, the left baffle 6 is telescopically arranged in the connecting slot, and the two ends of the lifting spring 5 are respectively connected to the left baffle 6 and the connecting slot. It is worth noting that since the above embodiment describes that the sliding block 11 first moves to the top of one end of the sliding slot, and the one end of the sliding block 11 is matched with one end of the sliding slot by lowering the height, this position is located at the left end of the sliding slot, that is, the sliding block 11 is retracted into the connecting slot by pressing the left baffle 6, so that one end of the sliding block 11 is matched with one end of the sliding slot. It is worth mentioning that the distance between the left baffle 6 and the right baffle 7 is equal to the length of the sliding block 11. After one end of the sliding block 11 is fitted with the right baffle 7, the left baffle 6 will release its press fit with the sliding block 11, and the left baffle 6 will extend out of the connecting slot again, so that the left baffle 6 and the right baffle 7 jointly limit the movement of the sliding block 11.
[0026] In addition, according to the construction method of the above embodiment, in order to further reduce the friction force during the sliding process of the bridge deck 2 and ensure that the sliding cylinder 3 can pull the bridge deck 2, a filling slot 202 is opened inside the bridge deck 2 of this solution, and a sealing slot 201 is also opened on the top of the bridge deck 2. The sealing slot 201 and the filling slot 202 are interconnected. The positioning unit also includes a sealing plate 8 and a sealing spring 9. The sealing plate 8 is slidably arranged in the sealing slot 201. The two ends of the sealing spring 9 are respectively connected to the sealing plate 8 and the inner wall of the bridge deck 2. The sealing plate 8 can lock or release its connection with the sealing slot 201. 1; it is worth mentioning that before the bridge deck 2 is installed, the sealing plate 8 locks its sealing cooperation relationship with the sealing slot 201. At this time, due to the hollow interior of the bridge deck 2, its mass is reduced, thereby reducing the friction during the sliding process of the bridge deck 2, making it convenient for the sliding cylinder 3 to pull the bridge deck 2; after the sliding cylinder 3 pulls the bridge deck 2 to the specified position, the sealing plate 8 will release its sealing cooperation relationship with the sealing slot 201, making it convenient for the subsequent cement filling of the interior of the bridge deck 2. Such a setting is also beneficial for construction personnel to judge whether the bridge deck 2 has been installed.
[0027] Specifically, in order to ensure that the sealing plate 8 will release its sealing cooperation relationship with the sealing slot 201 after the installation of the bridge deck 2 is completed, the positioning unit also includes a sealing rod 10, and the bridge deck 2 is provided with a connecting hole. The sealing rod 10 can be slidably connected coaxially with the connecting hole. One end of the sealing rod 10 is connected to the sealing plate 8, and the other end can lock or release its abutment cooperation relationship with the right baffle 7; through such a setting, after the sliding block 11 is matched with the sliding slot, the sealing rod 10 and the right baffle 7 are pressed and matched, driving the sealing rod 10 to move, and then driving the sealing plate 8 connected thereto to move, thereby releasing the sealing cooperation relationship between the sealing plate 8 and the sealing slot 201; it is worth noting that in order to ensure the cooperation between the sliding block 11 and the sliding slot, after the sealing rod 10 of this scheme completes sliding, it will be hidden in the side wall of the bridge deck 2 as a whole.
[0028] Furthermore, in order to ensure that the subsequent cement can be smoothly filled in the filling slot 202, the bottom height of the filling slot 202 increases or decreases along the laying direction of the bridge deck 2, and the sealing slot 201 is located at the top of the filling slot 202. Such a setting can ensure that cement can be poured into various parts of the bottom of the filling slot 202, and by observing whether the sealing slot 201 is filled with cement, it can be determined whether the filling slot 202 is fully filled.
[0029] In order to further supplement the working steps of S5, the following steps are also included: S51: When the crane controls the bridge deck 2 to descend, the bridge deck 2 presses the left baffle 6 on the head bridge deck 1 to shrink into the connecting slot; S52: The output end of the sliding cylinder 3 is hinged to one end of the bridge deck 2, and the output end of the sliding cylinder 3 is controlled to contract, so that the bridge deck 2 moves toward the right baffle 7; S53: After the end surface of the bridge deck 2 is in contact with the right baffle 7, the crane controls the height of the bridge deck 2 to descend, so that the bottom surface of the sliding block 11 is in contact with the bottom surface of the sliding slot; S54: After the sealing rod 10 is fitted with the right baffle plate 7, it shrinks in the bridge deck 2, so that the sealing plate 8 releases its sealing fitting relationship with the sealing slot 201; S55: Pour cement into the filling slot 202 until the interior of the bridge deck 2 is fully filled.
[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
