Description

Technical Field

[0001] The invention relates to the technical field of steel sheet pile construction, and in particular to an auxiliary hole-guiding method for intelligently inserting and driving steel sheet piles in non-uniform geology. Background Art

[0002] Steel sheet piles are steel structures with linkage devices on the edges, and such linkage devices can be freely combined to form a continuous and tight retaining wall or water retaining wall. Steel sheet piles are divided into two types according to the production process: cold-bent steel sheet piles and hot-rolled steel sheet piles. Cold-bent steel sheet piles are formed by continuous rolling by cold-bending units, and the side locks can be continuously overlapped to form a steel structure of a sheet pile wall. They are made of thinner plates and processed by cold-bending forming units. Its production cost is low and the price is cheap, and the fixed length control is more flexible. In engineering construction, the application scope of cold-bent steel sheet piles is relatively narrow, and most of them are only used as a material supplement. Compared with concrete piles, steel sheet piles have a light structure. The continuous wall composed of steel sheet piles has high strength and rigidity, good water tightness, and the lock joints at the steel sheet pile joints are tightly combined, which can be naturally anti-seepage and easy to construct. It can adapt to different geological conditions and soil qualities, reduce the amount of earth excavation in the foundation pit, occupy a small area for operation, and has good durability. Depending on the difference in the use environment, the service life can be up to 50 years. The construction is environmentally friendly, the amount of soil and concrete used is greatly reduced, which can effectively protect land resources and the operation is efficient. It is very suitable for the rapid implementation of disaster relief and prevention such as flood control, collapse, quicksand, and earthquake, and the materials can be recycled and reused. In temporary projects, compared with other single structures, the wall is lighter and has a greater ability to adapt to deformation, which is suitable for the prevention and treatment of various geological disasters.

[0003] In the process of steel sheet pile construction, geological conditions are the main factors affecting the construction effect of steel sheet piles. If the construction area has non-uniform geological conditions, high foundation bearing capacity, and narrow construction working surface, it will cause difficulty in driving the steel sheet piles and require repeated insertion and extraction. At the same time, forced driving will cause damage to the pile head, excessive deformation of the pile body, difficulty in engagement of the steel sheet piles, and difficulty in controlling the construction quality. It will also cause the pile driver to overload and cause damage to the pile driver, and it is easy to cause damage to the pile driver accessories and hydraulic oil pipe bursting, etc., which poses a safety hazard and affects the construction progress. Therefore, a method for intelligent driving and auxiliary hole guidance of non-uniform geological steel sheet piles is proposed to solve the above problems. Summary of the invention

[0004] The purpose of this application is to provide a method for intelligent insertion and auxiliary hole guidance of steel sheet piles in non-uniform geology to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the present application provides the following technical solution: a method for intelligently inserting and driving auxiliary holes for steel sheet piles in non-uniform geology, comprising the following steps:

[0006] S1: Selection of the construction scope of the auxiliary lead hole: Determine the location where the steel sheet pile construction is required according to the construction drawings and relevant instruments, and then use lime or other materials to mark the location of the steel sheet pile construction. After the construction location is marked, proceed to the next step;

[0007] S2: Measurement of steel sheet pile terrain and determination of pile hole depth: After the steel sheet pile construction position is determined, the initial position is selected as the starting point, and then the height of the ground is measured in turn according to the steel sheet pile construction direction. After the measurement is completed, the height difference between each steel sheet pile construction position and the initial steel sheet pile construction position is marked, and the steel sheet pile construction ground is leveled with one ground as the base point. After the leveling is completed, the lead hole spacing is determined, and the position and depth of the steel sheet pile to be driven into the ground are marked to facilitate the lead hole construction;

[0008] S3: Test hole to determine the auxiliary drilling construction parameters: After the pile hole depth is determined, select a construction point for test hole. When testing the hole, the steel sheet pile point with the largest depth should be selected for test hole. When testing the hole, analyze the soil and rock formation generated by the test hole, and determine the relevant data of the drilling according to the analysis results, and select the appropriate drilling equipment and construction points according to the determined data;

[0009] S4: Drilling construction: After the drilling related parameters are determined, a drilling analysis module is established according to the obtained drilling related parameters, and the drilling construction related parameters are written into the analysis module. Then, drilling data acquisition equipment and monitoring data are set around the drilling position, and the drilling pile position related information is collected through the data acquisition equipment. The collected information includes but is not limited to soil properties, drilling depth, drilling verticality, and drilling spacing. During the drilling construction process, the drilling construction related parameters are adjusted according to the real-time analysis data of the analysis module;

[0010] S5: Steel sheet pile driving construction: After the guide hole construction is completed, the holes are measured again to ensure that the holes of the guide hole construction meet the requirements of steel sheet pile construction. Before the steel sheet pile construction, the steel sheet piles and guide holes are numbered first, and the corresponding steel sheet piles are driven into the corresponding guide holes. During the steel sheet pile construction, the marked steel sheet piles are aligned with the center of the guide hole, and then the steel sheet piles are embedded in the guide hole by the pile driver to complete the driving of the steel sheet piles. After all the steel sheet piles are installed, the horizontality of the driven steel sheet piles is measured to ensure that all steel sheet piles are at the same height.

[0011] Preferably, during the hole construction, after the hole construction drilling rig is accurately positioned, the verticality of the drill rod of the drilling rig is adjusted to ensure that the drill rod is perpendicular to the construction surface. During the hole construction, the drilling rig should drill slowly to minimize the shaking of the drill rod. During the hole construction, the accumulated soil at the hole mouth should be cleaned at any time to prevent the soil from falling into the pile hole. The drill rod speed needs to be adjusted according to the geological conditions, and it is strictly forbidden to increase the drill rod speed at will.

[0012] Preferably, the drilling machine used for the hole construction needs to be calibrated after it is moved to the construction position. During the calibration, the drilling machine should be checked vertically from the front and side directions that are perpendicular to each other, using a hanging cone or a level ruler on the drilling rig platform. When both the front and side directions meet the requirements, it means that the drilling machine and the construction surface are drilling perpendicularly to each other. After the calibration, the drilling machine needs to be fixed and supported so that it does not tilt or move during drilling.

[0013] Preferably, during the hole construction, the hole depth should meet the design requirements. During the hole construction, a control depth scale should be set on the drill frame of the drilling machine. During the hole construction process, the hole depth should be observed and recorded in time to ensure that each hole position meets the steel sheet pile design requirements. When recording the hole depth, the construction depth can be controlled by marking dimension marks on the drilling rig column or other methods.

[0014] Preferably, during the steel sheet pile boring construction, the borehole diameter is determined according to the width of the steel sheet pile to be constructed. Under normal circumstances, the pile width ≦ boring diameter ≦ pile width + 10 cm. During the boring construction, the selection of the drilling rig used for the boring construction, the boring spacing and the depth are determined according to the soil and rock analysis results generated during the test hole.

[0015] Preferably, before the steel sheet pile is driven in, grease needs to be applied inside the locking mouth of the steel sheet pile. The grease applied is mainly a butter mixture ointment. When applying, ensure that the locking mouth of the steel sheet pile is evenly applied without omission. Grease is applied to the locking mouth of the steel sheet pile to facilitate the driving and removal of the steel sheet pile, while reducing the frictional resistance during driving and enhancing the anti-seepage performance.

[0016] Preferably, the inclination of each pile needs to be measured and monitored at any time during the steel sheet pile driving construction process. During construction, the inclination of the steel sheet pile cannot exceed 1%. When the inclination deviation of the steel sheet pile is not large, a steel wire rope is used to pull the steel sheet pile body for traction, and the steel sheet pile is driven while being pulled to gradually correct it so that the inclination of the steel sheet pile meets the requirements. When the deviation is too large and cannot be adjusted by the pulling method, the steel sheet pile needs to be pulled up and driven again.

[0017] Preferably, during the construction of the steel sheet piles, if a fan-shaped steel sheet pile wall phenomenon occurs, it is necessary to correct it immediately. During the correction, a winch is used to pull the steel sheet pile in the vertical direction during the insertion process until the vertical state is restored; if the steel sheet pile is twisted during piling, it is necessary to lock the front lock of the steel sheet pile with a card plate in the direction of pile travel to prevent the steel sheet pile from rotating during the sinking process; if during piling, if there is a common connection (that is, the adjacent piles that have been driven in during piling sink together), it is mainly because the steel sheet pile is obliquely bent, which increases the lock resistance. At this time, the piles that are connected together and other piles that have been driven can be temporarily fixed by welding one or several angle irons; when the steel sheet piles are vibrated into the soil layer, if there are underground debris and small stones, the steel sheet piles can be vibrated and pulled out and then driven in, and the steel sheet piles can be vibrated up and down and driven in many times until they are driven in.

[0018] Preferably, the steel sheet pile needs to be vibrated before construction. Before vibrating the pile, the pile clamp of the vibrating hammer should clamp the upper end of the steel pile, and make the center of gravity of the vibrating hammer and the steel sheet pile in the same straight line. When vibrating the pile, the vibrating hammer clamps the steel pile and lifts it, so that the steel sheet pile is vertically positioned or the locking mouth of the steel sheet pile is inserted into the locking mouth of the adjacent pile. After the pile is stable, correctly positioned and vertical, it is vibrated and sunk. Every time the steel sheet pile sinks about 2m, stop vibrating to check the verticality of the pile, and correct it in time if any deviation is found.

[0019] Preferably, during the steel sheet pile construction process, it is necessary to implement corresponding construction safety measures control, construction process environmental protection measures and construction emergency plans at various stages of the construction. At the same time, corresponding warning signs and reminder slogans are set up around the construction site, and professional safety personnel are arranged to conduct inspections during the overall construction process to prevent pedestrians from passing by the construction site.

[0020] In summary, the technical effects and advantages of the present invention are as follows:

[0021] In the present invention, before the steel sheet pile construction, the soil parameters and geological conditions of the steel sheet pile construction location are obtained through trial hole construction, and then an analysis module is established according to the relevant parameter conditions to analyze and predict the construction method and the problems that may be encountered in the construction, and the selection of hole-leading parameters under different geological conditions and foundation bearing capacity, the auxiliary hole-leading construction process and the construction method are studied, and the auxiliary hole-leading construction range, drilling rig selection, hole-leading spacing, hole-leading diameter, and hole-leading depth related data are determined according to different geological conditions and construction parameters. The degree of intelligence is high, which is conducive to the smooth progress of steel sheet pile construction. Then, before the formal steel sheet pile construction is carried out, the point where the steel sheet pile is located is pre-drilled and the hole-leading construction is carried out by a drilling rig, thereby changing the soil density within the hole-leading range of non-uniform geological conditions and high bearing capacity areas, reducing the soil resistance during the insertion and driving of steel sheet piles, and solving the difficulties caused by the inability to directly drive or repeated insertion and extraction, which is conducive to speeding up the construction progress, reducing safety hazards, and reducing the loss of steel sheet piles during the construction process.
