Description

Pile pressing moving guide equipment for severe conditions of bridge construction slope

Technical Field

The invention belongs to the technical field of bridge construction equipment, and particularly relates to pile pressing moving guide equipment for a bridge construction slope under severe conditions.

Background

With the development of urbanization construction and railway traffic, bridges are increasingly constructed, obstacles can be crossed through the bridges, smooth passing of vehicles is guaranteed, and in the bridge construction process, the stability of bridge columns is of great importance, and the bridge columns cannot be horizontally displaced, inclined or settled. Sometimes, river side slopes need to be protected to a certain extent to improve the stability of the river side slopes, but the existing side slope protection device has some defects when in use, for example, the existing side slope protection device generally directly drives positioning piles into soil to fix a protective net, the engagement capacity of the positioning piles and the soil is poor, the overall stability of a subsequent protective net is low, and the practicability of the device is reduced; when current side slope protector is making up the use, lack certain connection between the adjacent protector, lead to can not be convenient when follow-up concatenation fix a position the device, reduced the wholeness of device simultaneously.

The bridge is built on the foundation, the bridge is easy to build when the foundation is stable, and the foundation is unstable, namely a weak foundation, so that the foundation must be treated in advance before the bridge is built, and the stability of the bridge is improved. The weak foundation is characterized by loose soil, high water content and poor bearing capacity, and is characterized by easy settlement and slippage, and if the foundation is positioned on a side slope, the settlement and slippage are more serious, thus providing greater challenge for building a bridge. The construction method is characterized in that a weak foundation on a side slope is typically a road bridge constructed in a valley, and a large number of construction scenes exist in southern areas of China. In the river course side slope pile driving construction process, the anti-landslide treatment of the river course side slope should be considered while the bridge pile foundation is constructed. The existing slide-resistant piles are common reinforcing structures in slope reinforcing engineering, are arranged at different positions and depths of a slope and are generally vertically driven. The anti-slide pile penetrates through the landslide body to be deeply embedded and fixed in the slide bed, landslide thrust borne by the upper portion is transmitted to soil or rock mass of the slide bed on the lower portion of the pile through the pile body, and the landslide thrust of the loaded section of the pile body is balanced by means of lateral resistance of the pile body embedded and fixed in the rock mass of the slide bed, so that the effect that the reinforced slope body is in a stable state is achieved. Pile pressing construction depends on large machinery, and the existing large pile foundation equipment is mainly applied to bridge pile foundation construction, but when landslide pile construction is considered, embarrassment exists in the existing pile pressing construction due to the fact that the construction range is enlarged.

As shown in fig. 9, at a position close to the crane, the end fixing frame 26 is first fixed by lifting the movable electric hammer 30 with the end fixing piles 27 carried by the end fixing frame 26 as a basic guide frame and pressing the two end fixing piles into fixing passages on both sides of the end fixing frame 26, respectively. Two C-shaped rails 19 are fixedly connected to both sides of the end fixing frame 26, respectively, so that the proximal ends of the two rails are fixed. The two C-shaped rails 19 are fixed at their middle and end with tie plates 28 respectively to ensure that they are always parallel and fixed. The bottom of the far-end track is provided with a convex fixed seat which is fixed with the bottom layer through an anchor rod. It is further contemplated that a tie 47 of a certain height may be laid on the bottom of the two C-shaped rails 19 as shown in fig. 4. The sleeper can be used for improving the height of the track, and the sleeper with the corresponding height is paved according to the height of the top end of the sunk pile exposed out of the ground, so that the sunk pile for reinforcing the river bed and preventing landslide basically does not need to consider paving the sleeper.
