Frozen earth road section highway bridge construction intelligent support system and construction method thereof

Abstract

The invention discloses a frozen earth road section highway bridge construction intelligent support system and a construction method thereof. The frozen earth road section highway bridge constructionintelligent support system comprises a base, a support frame and a plurality of groups of support parts, wherein the base comprises a fixed layer block and a movable layer block arranged at the top end of the fixed layer block in a lifting manner; the support frame comprises a support block at the top end of the movable layer block; a groove is formed in the top end of the support block; a plurality of inserting holes are formed in the outer side of the groove; an inflatable cushion is arranged in the groove; inserting rods are fixed in the inserting holes; vertical rods are in butt joint withthe inserting rods; a transverse rod is connected between opposite inserting rods; butt joint rods are connected between the inserting rods at opposite-angle positions and are fixed above the transverse rods. The intelligent support system comprises a controller, a positioning sensing module and a lifting control module, wherein the positioning sensing module is used for sensing the variation ofup-down displacement of each position at the bottom end of the fixed layer block; and the lifting control module is used for controlling lifting of the movable layer block after receiving the information of the positioning sensing module. The frozen earth road section highway bridge construction intelligent support system is adapted to sedimentation of a frozen earth layer and ensures steady support for highway construction.

Description

technical field [0001] The invention relates to the technical field of highway construction, in particular to an intelligent support system for highway bridge construction on frozen soil sections and a construction method thereof. Background technique [0002] To build highway bridges on permafrost, it is necessary to consider the soil quality of the permafrost and adjust measures according to local conditions. The characteristics of permafrost are: permafrost has rheology, and its long-term strength is much lower than the instantaneous strength. Because of these characteristics, construction of engineering structures in permafrost regions must face two major dangers: frost heaving and thawing settlement. The construction period also needs to be considered. As the climate warms, the permafrost continues to degrade, which will lead to the loss of previously built supports. Due to the settlement of the frame, the support frame will sink or tilt, and the characteristics of the ...

Because of these characteristics, construction of engineering structures in permafrost regions must face two major dangers: frost heaving and thawing settlement. The construction period also needs to be considered. As the climate warms, the permafrost continues to degrade, which will lead to the loss of previously built supports. Due to the settlement of the frame, the support frame will sink or tilt, and the characteristics of the traditional support frame that cannot be adjusted with the settlement cannot compensate for the settlement during the construction period, which has a great adverse effect on the construction support
