[0002] The wharf is the key facility that ship safe stop, also is playing the indispensable convenient function in the cargo loading and unloading and transportation process. Among them, the high-pile wharf adopts the pile foundation plus the upper structure to form, and its pile foundation generally selects the steel pipe pile and installs through the sinking pile construction technology. In the current steel pipe pile sinking pile operation practice, generally adopts the steel pipe pile guide frame as the auxiliary tool to ensure the accuracy and high efficiency of sinking pile process.

[0003] However, the sinking pile construction technology in the prior art has certain limitations: that is, each sinking pile operation can only be constructed for single steel pipe pile, after completing the construction of a steel pipe pile, the steel pipe pile guide frame needs to be moved to the next predetermined position as a whole, so as to continue the construction of the next steel pipe pile. This way of construction one by one, the steel pipe pile guide frame needs to be moved frequently, therefore a lot of time is consumed, which leads to the extension of the overall construction period and the low construction efficiency. Therefore, the steel pipe pile guide frame in the prior art has the problems of long construction time and low construction efficiency in the sinking pile construction. SUMMARY

A plurality of positioning columns are used for fixing the guide frame in the foundation, and play the role of supporting and fixing the whole guide frame. The guide wheels can form effective lateral constraint on the steel pipe pile from four directions respectively. The position of the corresponding guide wheel is adjusted by the bracing component, so that the guide wheel applies appropriate pressure on the steel pipe pile, the effect of correcting the perpendicularity of the steel pipe pile can be realized, and then the perpendicularity of the steel pipe pile is restored to the predetermined range.

[0011] When the steel pipe pile is in pile sinking construction, the bottom end of the steel pipe pile passes through the guide frame, the guide wheel is used for supporting the side wall of the steel pipe pile and can provide horizontal supporting force for the steel pipe pile. A plurality of guide frames are arranged along the length direction of the upper guide beam, so that after the guide frame is installed in place, a plurality of steel pipe piles arranged in a straight line can be subjected to pile sinking operation at one time, and after the pile sinking operation of the batch of steel pipe piles is completed, the guide frame is moved to the next position.

The two steel pipes can increase the sectional moment of inertia of the positioning column in the direction perpendicular to the length direction of the upper guide beam, thereby effectively improving the anti-tilting ability of the entire guide frame in this direction, and further strengthening the lateral stability of the guide frame as a whole.

[0020] Preferably, the upper guide beam includes two first stringers, the two first stringers are arranged side by side and horizontally, a plurality of guide frames are arranged between the two first stringers, the top of each positioning column is connected to a first cross beam, the first cross beam is perpendicular to the length direction of the upper guide beam, the two ends of the first cross beam are respectively connected to the first stringers, the bottom surface of the first cross beam is connected to the top of the two steel pipes, and a first inclined brace is connected between the first cross beam and the two steel pipes.

The cross-sectional shape of the steel pipe pile is generally circular, so the position where the protruding block contacts the steel pipe pile can also be designed as a circular arc, and the radius of the circular arc is consistent with the radius of the circular cross-section of the steel pipe pile.

[0024] Preferably, each of the guide frames can move along the length direction of the upper guide beam.

[0086] Embodiment 2

[0087] Take a specific project as an example, the project needs to construct ten rows of steel pipe piles 12, each row contains seven steel pipe piles 12. In order to efficiently assist the pile construction of these steel pipe piles 12, a steel pipe pile guide frame for multi-pile construction described in embodiment 1 is adopted. The guide frame is equipped with seven guide frames 4, which matches the number of steel pipe piles 12 to be constructed in each row.

[0088] The construction process is as follows: first, install the guide frame above the first row of the predetermined steel pipe pile 12 construction position. Then, align the bottom of the seven steel pipe piles 12 one by one and pass through the corresponding guide frame 4 until they stand stably on the ground. At this time, the construction work of the steel pipe pile 12 can be started, such as hammering and sinking.

[0089] When the seven steel pipe piles 12 of the first row are all constructed, the entire guide frame is translated to the construction position of the second row of the predetermined steel pipe pile 12 above, and the above construction process is repeated until the ten rows of steel pipe piles 12 are all constructed.

[0090] It is worth noting that during the entire construction process, the guide frame only needs to be moved ten times (once for each row), compared with the cumbersome process of moving the guide frame once for each steel pipe pile 12 in the traditional method. Using the guide frame described in the present application, the construction period can be shortened and the construction efficiency can be greatly improved.

[0091] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
