Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and specifically relates to an extra-long locking steel pipe pile inserting and driving guide device. Background Art

[0002] At present, the construction of underwater bridge pile foundation pedestals requires the use of cofferdams to provide a dry construction environment. Locking steel pipe piles, as one of the commonly used forms of cofferdam structures, often face the problem of difficult control of the verticality of the steel pipe piles and the closing accuracy between the locking buckles.

[0003] In particular, extra-long locking steel pipe piles are prone to displacement and tilt during the vibration hammering process, which affects the pile formation and closure. The traditional locking steel pipe pile positioning guide inserts the locking buckle of a steel pipe pile into the locking buckle of an already formed pile, and then connects the steel pipe piles into a whole in sequence, which can only ensure the accurate plane position of a single steel pipe pile. This requires multiple adjustments to the tilted or offset steel pipe piles during the insertion process, and may also damage the locking buckle of the steel pipe pile, which in turn affects the construction period and cost.

[0004] The utility model patent with announcement number CN220538642U disclosed on February 27, 2024 a steel pipe pile driving guide device, which includes an anchor frame and a limit assembly, two anchor frames are arranged at intervals along the second direction and extend along the first direction, the anchor frame includes an upper load-bearing bracket, a lower load-bearing bracket and an anchor steel pipe pile, and multiple anchor steel pipe piles in the same anchor frame are arranged at intervals along the first direction, the upper load-bearing bracket and the lower load-bearing bracket are arranged on the anchor steel pipe pile at intervals, and the distance between the upper load-bearing bracket and the lower load-bearing bracket is less than the length of the anchor steel pipe pile; the limit assembly includes an upper limiter and a lower limiter, which are respectively arranged on the upper load-bearing bracket and the lower load-bearing bracket and correspond to each other one by one, and the upper limiter and the lower limiter can abut against the locking steel pipe pile. The guide device has a complex structure and high cost of use. Utility Model Content

[0005] The utility model aims to provide an extra-long locking steel pipe pile driving guide device with a simple structure, which reduces the difficulty of operation, ensures the quality of pile formation, shortens the construction period, and aims to solve the deficiencies of the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The super-long locking steel pipe pile driving guide device comprises a limiting beam, the steel pipe pile comprises a driven steel pipe pile and an auxiliary steel pipe pile, a steel pipe pile matching section is arranged between the driven steel pipe pile and the auxiliary steel pipe pile; the limiting beam is arranged in parallel on both sides of the steel pipe pile matching section, the driven steel pipe pile and the auxiliary steel pipe pile, and a fixed structure is connected between the limiting beams.

[0008] The fixed structure comprises a fixing frame, which is fixedly connected to both ends of the limiting beam and is an "X"-shaped structure; the steel pipe pile matching section, the driven steel pipe pile and the auxiliary steel pipe pile are all fixedly connected to the limiting beam.

[0009] The steel pipe pile matching sections, driven steel pipe piles and auxiliary steel pipe piles are all provided with lock buckles, which are located in the same straight line; the steel pipe pile matching sections are arranged at equal intervals between the limiting beams, and the interval between adjacent steel pipe pile matching sections is equal to the diameter of the steel pipe piles.

[0025] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of the embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution and to facilitate their implementation.

[0026] like Figures 1 to 3 As shown, the super-long locking steel pipe pile driving guide device includes a limiting beam 1, and the steel pipe pile includes a driven steel pipe pile 2 and an auxiliary steel pipe pile 3. A steel pipe pile matching section 4 is provided between the driven steel pipe pile 2 and the auxiliary steel pipe pile 3; the limiting beam 1 is arranged in parallel on both sides of the steel pipe pile matching section 4, the driven steel pipe pile 2 and the auxiliary steel pipe pile 3, and a fixed structure is connected between the limiting beams 1. The limiting beam 1 is placed along the driving direction of the locking steel pipe pile, and the limiting beam 1 provides a connection position and installation guide for the steel pipe pile matching section 4. The fixing frame 5 is firmly welded to the limiting beams 1 on both sides, and plays a role in connecting and fixing the limiting beam 1. The steel pipe pile matching section 4 is used to match the driven and to-be-driven steel pipe pile lock 6, and the auxiliary steel pipe pile 3 is used to place and support the guide device, and the fixing frame 5 forms the overall guide device as a whole.

[0027] like Figures 1 to 3As shown, the fixed structure includes a fixing frame 5, which is fixedly connected to both ends of the limiting beam 1, and the fixing frame 5 is an "J"-shaped structure; the steel pipe pile matching section 4, the driven steel pipe pile 2 and the auxiliary steel pipe pile 3 are all fixedly connected to the limiting beam 1. The limiting beam 1 is welded to both sides of the above-mentioned steel pipe pile, and the fixing frame 5 is set at both ends of the limiting beam 1, so that the entire limiting device is formed as a whole to improve the rigidity of the entire guiding device. The guiding device can also be assembled on the trestle platform and can be installed as a whole on the driven steel pipe pile 2 and the auxiliary steel pipe pile 3, thereby ensuring the stability of the subsequent driving process. The fixing frame 5 is designed to be an "J"-shaped structure, and the middle part of the fixing frame 5 is higher than the upper end of the steel pipe pile, which will not interfere with the installation process of the steel pipe pile.

[0028] like Figure 1 As shown, the steel pipe pile matching section 4, the driven steel pipe pile 2 and the auxiliary steel pipe pile 3 are all provided with lock buckles 6, and the lock buckles 6 are in the same straight line; the steel pipe pile matching section 4 is arranged at equal intervals between the limit beams 1, and the interval between adjacent steel pipe pile matching sections 4 is equal to the diameter of the steel pipe pile. In the above structure, the lock buckles 6 are in the same straight line, which is convenient for the accurate engagement between the lock buckles 6 during the lowering process of the steel pipe pile; when two adjacent steel pipe pile matching sections 4 are placed, there is just enough space for a steel pipe pile to be driven in the middle, which is convenient for the engagement and matching between the lock buckles 6 during the driving, and can be driven smoothly and accurately. During construction, the steel pipe pile is lowered into the empty space between the adjacent steel pipe pile matching sections 4. Since the steel pipe pile matching section 4 is short, the lock buckle 6 can be accurately engaged without causing too much obstruction to the lowering process of the steel pipe pile, thereby improving the construction accuracy and efficiency. The steel pipe pile will not tilt or deflect. Since the steel pipe pile matching section 4 is short, the contact area between it and the lock buckle 6 of the lowered steel pipe pile is small, thereby avoiding damage to the lock buckle 6 of the steel pipe pile.

[0029] like Figure 1 As shown, the tops of the steel pipe pile matching section 4, the driven steel pipe pile 2 and the auxiliary steel pipe pile 3 are at the same height, and the bottom of the steel pipe pile matching section 4 is in the same plane as the bottom of the limiting beam 1. The above structure forms two positioning references for the top and bottom ends of the steel pipe pile matching section 4, ensuring the accuracy of the steel pipe pile matching section 4 during welding and the installation of the guide device.

[0030] like Figure 3 As shown, the steel pipe pile matching section 4 is consistent with the diameter of the steel pipe pile. The steel pipe pile matching section 4 is cut from the steel pipe pile to be driven, so the two have the same model, diameter and specification, which is conducive to reducing costs, not only ensuring that the installed limit beam 1 remains parallel, but also ensuring the matching and engagement of the steel pipe pile lock 6.

[0031] like Figure 1As shown, the driven steel pipe pile 2 is engaged with the adjacent steel pipe pile matching section 4, and the auxiliary steel pipe pile 3 is engaged with the adjacent steel pipe pile matching section 4. The above structure can first connect the device with the driven steel pipe pile 2 and the auxiliary steel pipe pile 3 to achieve a preliminary fixing effect, and add multiple fixing points to the overall guide device, which is conducive to improving the overall stability and the accuracy of subsequent construction.

[0032] like Figure 2 and Figure 3 As shown, the limit beam 1 is an I-beam, and the fixing frame 5 is formed by welding the I-beams. The limit beam 1 and the fixing frame 5 both adopt an I-beam structure, which has high structural strength, is easy to connect, and has low material cost.

[0033] The installation process of the locking steel pipe pile using the guide device is as follows:

[0034] First, on the trestle platform, the matching sections 4 of the multi-section steel pipe piles are welded and fixed along the length direction of the limiting beam 1, and the locking buckles 6 of the steel pipe piles are kept at the same horizontal position, leaving space for lowering the steel pipe piles between the adjacent matching sections 4 of the steel pipe piles; then, the processed fixing frame 5 is welded to the two sections of the limiting beam 1 to increase the stability of the overall structure; finally, the guiding device is placed on the driven steel pipe piles 2 and the auxiliary steel pipe piles 3, and the steel pipe piles are lowered after the plane position is accurately remeasured.

[0035] The steel pipe pile matching sections 4 located at both ends of the limiting beam 1 are respectively engaged with the driven steel pipe piles 2 and the auxiliary steel pipe piles 3 through the locking buckles 6, and then the steel pipe piles are lowered into the empty spaces between the adjacent steel pipe pile matching sections 4. The steel pipe pile matching sections 4 are short in length, which ensures the accuracy of lowering, engaging and driving the steel pipe piles. Then the steel pipe pile matching sections 4 are removed, that is, empty spaces for lowering steel pipe piles are formed between the driven steel pipe piles 2, and the steel pipe piles are lowered and driven in the empty spaces. Since the driven steel pipe piles are accurately positioned, the subsequent installation of the driven steel pipe piles is guaranteed to be smooth. Through the above operations, the steel pipe piles are accurately engaged with the locking buckles 6 in batches, the operation difficulty is reduced, the pile quality is high, and the effect of reusing the steel pipe pile matching sections 4 is achieved.

[0036] The extra-long locking buckle steel pipe pile driving guide device solves the problems of easy deviation and inclination of the extra-long locking buckle steel pipe pile during driving and difficulty in engagement between the locking buckles 6. By using the steel pipe pile matching section 4, the installation method of sequential driving through the locking buckles 6 in the prior art is changed, the operation difficulty is reduced, and the installation of the locking buckle steel pipe pile is achieved in batches. At the same time, damage to the locking buckle 6 of the steel pipe pile is avoided, the quality of the pile is ensured, the process of adjusting the offset and inclination during the driving process is saved, and the construction period is shortened.

[0037] The guide device also has the following advantages:

[0038] 1. It can be directly placed and fixed on the steel pipe piles with inserted lock buckles to avoid welding the brackets on the steel casing and ensure the stability of the structure. It has the function of directly locating the plane positions of multiple steel pipe piles to avoid multiple positioning and measurement.

[0039] 2. Directly insert the locking steel pipe piles between the adjacent matching locking steel pipe piles to achieve fast and accurate insertion, thus improving the construction accuracy and work efficiency.

[0040] 3. It is assembled with steel sections and locking steel pipe piles, which can be processed and formed by yourself. The length and placement height can be adjusted and can be reused many times. It has a simple structure, low cost and high economic benefits.

[0041] 4. It is placed on the top of the locking steel pipe pile, and the locking steel pipe pile is located at the edge of the trestle, with a large construction area, which is convenient for construction workers.

[0042] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
