A cap beam mounting method achieving mutual constraint of adjacent pier columns in a prefabricated bridge, in which a cap beam formwork is provided in the form of a cap beam, comprising: respectively fixedly providing limit steel rings (13) at two ends of a rectangular framework (12), and vertically providing steel bar sleeves (18) in the limit steel rings (13); in a mounting process, hoisting the cap beam formwork onto the tops of two adjacent prefabricated pier columns (2), so that pier column pre-embedded steel bars (15) protruding at the tops of the two prefabricated pier columns (2) are inserted into the steel bar sleeves (18) at the two ends of the cap beam formwork in a one-to-one corresponding manner, and the two adjacent prefabricated pier columns (2) are limited in the cap beam formwork. The method can significantly improve the construction efficiency for mounting a cap beam and ensure the project quality.

A pavement flatness measurement method and system. The measurement method comprises: acquiring three-dimensional point cloud data of a pavement; performing reverse modeling by using the point cloud data to obtain a pavement entity model; building an eight-wheel flatness measuring instrument model in equal proportion, and constraining the connection relationship of all parts; enabling the eight-wheel flatness measuring instrument model to move on a specified characteristic line of the pavement entity model by using a motion simulation technology, to obtain a pavement irregularity deviation value of each pavement measurement interval; and calculating the flatness value of the pavement according to the pavement irregularity deviation value. The system comprises an acquisition module (10), a pavement entity model building module (20), a flatness measuring instrument model building module (30), a pavement irregularity deviation value calculation module (40), and a flatness calculation module (50). The measurement method and system can be applied to curved pavements and large-slope pavements, and has strong feasibility and practicability.

Abrégé

The invention discloses a combined construction method and system of vacuum
pipe well combined with pneumatic fracturing in deep soft soil foundation, the

construction method comprising: vacuumizing a sealed pipe well by a vacuum
pump
so that negative pressure is formed in the pipe well, at the same time
delivering the
gas extracted by the vacuum pump to a pressurizing tank, then the pressurizing
tank
injecting the high pressure air into the soft soil between the pipe wells to
produce
pneumatic fracturing in the soil body; expanding the flow path of groundwater,
and
accelerate the dewatering rate of the pipe well and thus promote the
precipitation
consolidation of the soft soil. This method effectively solves the problems
that the
traditional (vacuum) pipe well dewatering method is not effective to treat the
soft clay
layer with low permeability and the precipitation rate is not high.
