Among them, the gate pier joints are a more commonly used design scheme because they can ensure the integrity of the gate hole structure and avoid gate leakage caused by uneven settlement of the gate piers. In addition, the existing construction method of the split gate pier is to first construct the gate pier on one side of the split gate pier, and then construct the gate pier on the other side after the construction of one side is completed.

[0027] The pre-embedded vertical main reinforcement 3 of the split gate pier is located inside the erected steel formwork. A plurality of tie rods 4 are provided between the steel formwork and the vertical main reinforcement. The tie rods are all made of steel bars. The plurality of tie rods are arranged at intervals along the height direction and the length direction of the structural joint. The spacing between two adjacent tie rods in the same direction does not exceed 60 cm. The tie rods and the vertical main reinforcement are vertically connected, and the two are connected by welding; the ends of the tie rods are connected to the steel formwork to fix the steel formwork.

[0028] The asphalt fir wood formwork set at the joint of the split gate pier structure is a whole asphalt fir wood formwork composed of multiple asphalt fir boards spliced ​​together. A fixing piece is provided between two adjacent asphalt fir boards. The fixing piece adopts a limiting sleeve 10. The connecting ends of the two adjacent asphalt fir boards are respectively inserted into the limiting sleeves to realize the limited splicing of the two asphalt fir boards.

[0029] At the same time, a limiting support is provided between the vertical main reinforcement arranged at the joint and the asphalt fir formwork, and the limiting support includes a plurality of positioning devices 8 and a plurality of fixing devices 9; the positioning device is arranged at the bottom of the structural joint, and the plurality of positioning devices are arranged at intervals along the bottom of the asphalt fir formwork, which are used to fix the bottom of the asphalt fir formwork, and the bottom of the positioning device is connected to the bottom plate of the gate chamber; the specific positioning method of the positioning device includes: the positioning device 8 includes a positioning rod 15 and a first connecting rod 7, the positioning rod is arranged at the end of the first connecting rod, and the positioning rod is vertically connected to the first connecting rod; the positioning device relies on the first connecting rod to connect the vertical main reinforcement embedded at the joint of the gate pier, relies on the positioning rod to support the asphalt fir board, realizes the clamping and fixation of the asphalt fir board, and at the same time the bottom of the positioning steel is connected to the bottom plate of the gate chamber. The fixing device is arranged at the connection part of two adjacent asphalt fir boards in the asphalt fir formwork, and is used to fix the connection part of the asphalt fir boards; the specific fixing method of the fixing device includes: the fixing device 9 includes a fixing rod 16 and a second connecting rod 17, the fixing rod is arranged at the end of the second connecting rod, and the positioning rod is vertically connected to the second connecting rod; the fixing device relies on the second connecting rod to connect the vertical main reinforcement pre-buried at the gate pier joint, and relies on the fixing rod to support the connection part of the asphalt fir board to achieve the clamping and fixing of the connection part of the asphalt fir board. The positioning rod, the fixing rod and the connecting rod of the positioning device and the fixing device are all made of the relatively short steel bars remaining in the process of steel bar cutting. The connecting rods of the two are respectively welded to the middle sections of the positioning rod and the fixing rod, and the other end of the connecting rod is welded to the vertical main reinforcement. In addition, the vertical main reinforcements on both sides of the gate pier joint are tied with tie bars 14 for fixing, so as to enhance the stability of the vertical main reinforcements on both sides and prevent the main reinforcements from deforming, which affects the positioning, fixing and installation of the asphalt fir formwork.

[0030] There are multiple through holes on the asphalt fir formwork, and the positions and diameters of the through holes match the tie rods. The tie rods cross the through holes of the asphalt fir formwork to further support and fix the asphalt fir formwork; at the same time, the asphalt fir formwork is clamped and fixed by the limit support, which effectively prevents the asphalt fir formwork from offset and ensures the positioning and installation accuracy of the asphalt fir formwork. In addition, the asphalt fir formwork adopts a splicing structure, and multiple asphalt fir boards are positioned and installed one by one, which is easy to install and has high positioning accuracy, avoiding the problem that the volume and area of ​​a single asphalt fir board are too large, making it difficult to transport and hoist and install, and the problem that the volume and area of ​​a single asphalt fir board are large, resulting in difficult to control the positioning accuracy of the installation.

[0031] The present invention also provides a split gate pier construction process, including the above-mentioned split gate pier construction complete set device, the split gate pier includes a pier 1 and a pier 2 set in the split; during the split gate pier construction process, the piers 1 and 2 on both sides of the split are synchronously constructed and cast at the same time, specifically including: building a scaffold, laying and installing the split gate pier construction complete set device and casting the split gate pier. The specific implementation is as follows:

[0032] Pier 1 and Pier 2 on both sides of the split gate pier are divided into multi-layer pier bodies 12 according to the overall height of the split gate pier under construction. In this embodiment, Pier 1 and Pier 2 are divided into four layers of pier bodies, and the four layers of pier bodies are synchronously constructed from the bottom layer to the top layer, and cast at the same time; that is, each layer of pier body is constructed according to the same construction process, starting from the first layer of the split gate pier, scaffolding is built around the first layer of pier bodies of Pier 1 and Pier 2 of the split gate pier, steel bar production and installation (cutting and making the steel bars required for the complete set of split gate pier construction equipment, including limit support parts, tie rods and vertical main bars, etc.), water-stop copper sheet installation, asphalt fir board installation and fixation, steel formwork installation and fixation, and the first layer of pier bodies of Pier 1 and Pier 2 are cast at the same time; after the first layer of pier body construction is completed and the forming and stable strength reaches the standard, the second layer of pier body construction is carried out according to the above process until the top layer of pier body casting of Pier 1 and Pier 2 is completed. The strength standard is based on the strength requirements of the pier body design, and the existing industry strength requirement standards can be specifically referred to.

[0033] When pouring each layer of piers 1 and 2 at the same time, the two sides of piers 1 and 2 are poured alternately. 30cm thick concrete is laid on one side, and then 50cm thick concrete is laid on the other side. The height difference of concrete on both sides of the joint does not exceed 30cm; until the pouring of the pier body of this layer is completed. By limiting the height difference of concrete pouring on both sides of piers 1 and 2 and adopting the method of alternate pouring, it is ensured that the asphalt fir board will not bend, which not only ensures the stability of the pouring of the split gate pier, but also improves the construction efficiency of the split gate pier.

The complete set of equipment is used to change the original single-side construction of the split gate pier into simultaneous construction on both sides of the split gate pier. Asphalt fir boards with certain rigidity and strength are selected as filling materials for structural seams of the split gate pier, which can serve as templates. The asphalt fir templates are precisely positioned and fixedly installed in conjunction with limiting supports and tie rods. This not only solves the problem of difficulty in installing flat steel templates at the seams of single-side construction of the split gate pier, but also improves the installation accuracy of the water-stop copper sheet, ensuring that the center line of the copper nose part of the water-stop copper sheet can coincide with the center line of the structural seam, but also realizes the construction goals of "simultaneous construction, simultaneous pouring" and reaching the top together for the split gate pier, effectively shortens the time required for the construction of the split gate pier, saves construction period and labor costs, and saves at least 30% of construction period compared with the existing single-side split gate pier construction.
