The invention relates to a construction method for hollow-block mound breakwater. At first, according to layered placing principle that hollow blocks between layers are set in plum shape and they are set in plum shape in 3-D space finally, aiming to different breakwater segments models are set. Then the group with good anastomosis of section contour line and optimal porosity is selected and designed so that under the condition that elevation of bottom face of section is appointed space of rows and columns is confirmed; namely parameters of indoor placing experiment with different breakwater height are confirmed as control parameters in field placing construction. They are inputted into computer. And then position sensor is set on the placing lifting machine to measure the practical position of hollow block under the water and measured data is transmitted into the computer. Parameters of practical positions of hollow block are compared with parameters of indoor placing experiment and builders ...

The invention relates to the building technology field, in particular to the field of dock building technology. The invention discloses a vertical control method for the sinking and setting of steel buoyant boxes, comprising the following steps: the measurement of a pile top elevation, the prefabrication of the concrete cushion block of the pile top, the installation of the concrete cushion block of the pile top, the tossing arrangement of a broken stone hardcore, the underwater casting of a concrete layer, and the tossing arrangement of a broken stone leveling course. The vertical control method for the sinking and setting of steel buoyant boxes provided by the invention can effectively control the installation precision of the steel buoyant boxes, especially the integral transversal and longitudinal inclination degree after the bedding of the steel buoyant boxes, thus laying the foundation for the subsequent smooth installation of a transversal pulling door. Meanwhile, the method provided ...
