As an optional embodiment, the current construction stage is a steel sheet pile hole guiding construction stage, a steel sheet pile construction stage, a cofferdam folding construction stage, an installation support construction stage, a foundation pit excavation dredging construction stage, a bottom sealing concrete pouring construction stage, a bearing platform pier column construction stage or a cofferdam dismantling construction stage.
In a specific embodiment, the construction process of the cofferdam project comprises the following steps:
step 1, measuring lofting construction: marking trestle construction control points, checking, effectively protecting, positioning by using the existing steel pipe piles and steel pile casings, welding I-steel plates on the steel pipe piles (the existing and later-added enclosing purlin piles) as guide beams by using the outer steel sheet piles, welding I-steel plates on the steel pile casings as guide beams by using the inner steel sheet piles, and ensuring that the beaten steel sheet piles are on a straight line by using the I-steel. As guiding position and elevation control mark during piling.
And 2, hole guiding construction of the steel sheet pile: the hole guiding adopts a pneumatic down-the-hole hammer, the diameter of the hole is 600mm, the distance between the holes is 500mm (the lap joint length between two holes is 20 cm), and the holes are sequentially guided to the elevation of the pile bottom. Before construction, marking is carried out on a drill rod, and the depth of a guide hole is controlled to be smaller than the depth of the designed rock entering (more than or equal to 0.9 m).
And 3, construction of steel sheet piles: the steel sheet pile is hoisted to the trestle by adopting a 50T crawler crane, the pneumatic down-the-hole hammer is mechanically matched with a rattan 2045 steel sheet pile machine to carry out steel sheet pile construction on the rest part of a steel trestle platform (the steel sheet pile is guaranteed to meet the design pile length or rock entering depth is more than or equal to 0.9 meter), welding extension is adopted for the steel sheet pile exceeding 18 meters, inserting and driving are carried out after welding is finished, when the steel sheet piles are welded and spliced, the two steel sheet piles are aligned and tightly propped, clamped in a firm clamp for welding and are firmly welded, meanwhile, the splice joint of the steel sheet pile on the same section of the cofferdam is not more than 50%, the joint of the adjacent piles is staggered up and down by not less than 2 meters, dislocation is adopted after the welding of the steel sheet pile is finished, and special electric welding personnel are adopted for repairing and welding steel sheet pile plugging is adopted at the welding position.
And 4, closure construction of the cofferdam: the plane of the steel sheet pile cofferdam is square, so that corners can be formed in the longitudinal direction and the transverse direction of the cofferdam, and shaping corner piles are used at construction corners. In order to facilitate the folding, two adjacent piles at the folding position are one high and one low, each steel sheet pile is driven to be perpendicular to the tangential direction along the normal line of the guide frame, the folding is selected to be near the corner pile (generally 5 piles are separated from the corner pile), if the distance is different, the distance between the adjacent sides of the folding edge and the guide frame can be adjusted, and in order to prevent the two piles at the folding position from being out of a plane, the direction of the corner pile is necessarily adjusted, and one side locking opening of the corner pile and the opposite steel sheet pile locking opening of the corner pile should be kept parallel as much as possible.
And 5, mounting and supporting construction: pile foundation steel pile casing is cut before installing and welding bracket, and supporting bracket is arranged on the steel sheet pile for setting up the shaped steel purlin, so that the purlin bracket is converted into the steel sheet pile by the steel pile casing. When the supporting brackets of the second, third and fourth layers of enclosing purlins are arranged on the steel sheet pile, a construction line is required to be pulled to ensure that the top surfaces of the brackets are positioned on the same horizontal plane. And after the purlin is installed, a reverse bracket is arranged on the purlin.

And 7, pouring construction of bottom sealing concrete: the bottom sealing concrete is intensively fed by adopting a commodity concrete mixing plant, and is pumped to the bottom of the foundation pit by adopting a day pump in a construction site. The bottom sealing concrete pouring adopts an underwater concrete pouring process, the bottom of a hose of a top pump is controlled to be about 20cm away from the bottom of a river bed, after the first concrete is poured, the elevation of a concrete top at the bottom opening of the hose is measured, and the burial depth of the hose is ensured to be more than 0.5 m. In the pouring process, the elevation is measured at intervals according to the pouring quantity, so as to guide the pump pipe of the overhead pump to move, and the concrete is uniformly lifted. In order to monitor the pouring condition of the back cover concrete at any time, 10 measuring points are arranged. When the concrete is poured and approaches to a junction, the elevation of the concrete surface is comprehensively measured, and the pouring quantity is increased near the measuring point with the lower elevation of the concrete surface according to the measuring result until the measured result meets the requirement.
And 8, construction of bearing platform pier columns: and carrying out bearing platform pier column construction according to the conventional construction process of steel bar binding, template installation and concrete pouring.

Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., a field programmable gate array (Field Programmable gate array, FPGA)) is an integrated circuit whose logic function is determined by the user programming the device. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware DescriptionLanguage), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (RubyHardware Description Language), etc., VHDL (Very-High-SpeedIntegrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component.
