The invention relates to an assembled supporting frame for prefabricated stair performance detection. The assembled supporting frame comprises a height-adjustable bearing beam. The bearing beam is used for bearing a prefabricated stair, and the two ends of the bearing beam are detachably connected with supporting pieces. The bottoms of the supporting pieces are detachably connected with stabilizing supports. The height of the bearing beam can be adjusted according to the height of a prefabricated stair component, the assembled supporting frame is suitable for prefabricated floor components with different sizes, the effect that the device is recycled is achieved, different supporting devices do not need to be designed for the components with different sizes, the detection cost of the prefabricated stair component can be effectively reduced. Moreover, the assembled supporting frame is simple in structure, convenient to use and low in manufacturing cost, all components can be disassembledand assembled to achieve the purposes of convenient transportation and on-site installation, rapidness and convenience are achieved, and therefore the completion efficiency of performance testing ofthe prefabricated stair component can be greatly improved, and the improvement of the construction production efficiency of a prefabricated building is promoted.

The invention relates to the field of building operations, in particular to a device for hoisting prefabricated reinforced concrete column on site and a walking technology thereof. The purpose of the invention lies in providing a simple yet effect walking technology for hoisting prefabricated reinforced concrete column on site and the device for realizing the technology; the design is simple and the operation is effective. To achieve the purpose, the invention provides the following technical proposal: the device of the invention is composed of a wheeled supporting plate, steel sheets and braking angle iron and has the following characteristics: the supporting plate is a right-angle structure, the top of the right angle is provided with deflectable rolling-over wheels, the two ends of thesupporting plate far away from the top of the right angle are respectively provided with deflectable wheels, rotary connecting rods are arranged on a deflectable wheel seat. With the device of the invention adopted, mechanical efficiency can be effectively improved, construction productivity can also be enhanced, thus accelerating construction progress and enjoying extremely noticeable economic benefits and comprehensive benefits.

The invention discloses a damping spring vibration isolator device with expansion sleeves. The device comprises an upper bearing plate component, wherein the upper bearing plate component and a lower bearing plate component are connected with an upper sleeve and a lower sleeve for mounting a damper component; the upper and lower ends of the damper component are connected into the upper sleeve and the lower sleeve through the expansion sleeves respectively; the bottom of the lower bearing plate component is connected with a height adjusting component. A mounting and adjusting construction method of the damping spring vibration isolator device with the expansion sleeves comprises the following steps: assembling the damping spring vibration isolator device with the expansion sleeves; arranging the damping spring vibration isolator device with the expansion sleeves at an equipment foundation; adjusting height, releasing pre-compression of the spring and adjusting the height again. The damping spring vibration isolator device with the expansion sleeves can be locked after the upper and lower bearing plate components and the spring are assembled and the pre-compression is applied, and is convenient to assemble and reliable to connect; the length of the damper and the height of the vibration isolator are rational; the damping spring vibration isolator device with the expansion sleeves is adjustable in height; the mounting and adjusting construction method is simple and convenient; the precision is guaranteed; the construction efficiency is favorably improved; the construction period is shortened.

The invention discloses a technique for fast filling a constructed wetland in a shore area. A jetty and a separation cofferdam are adopted to divide the wetland into a plurality of hydraulic reclamation areas as required; each hydraulic reclamation area is constructed independently, so that the construction production efficiency is improved and the construction period is shortened. A bucket-wheel type dredger instead of a common cutter suction dredger is adopted to perform hydraulic reclamation construction, the discharged soil is small blocks, has the characteristic of partial saturation, is relatively shorter in solidification time, and can meet the requirement of planting plants in the wetland in short time. The bucket-wheel type dredger is utilized to borrow earth from a lake region, and the borrow pit of the separation cofferdam is filled and leveled up in an equal quantity replacement manner by adopting the hydraulic reclamation manner, so that the production efficiency is effectively improved, the project cost is reduced, and the cost is decreased. A high-strength geotechnical cloth is arranged on the inner side of the jetty, so that the hydraulic reclamation earthwork in the wetland is prevented from entering the lake region through the holes of the jetty, and the pollution to the lake water is reduced; the water permeability of the high-strength geotechnical cloth enables the water bodies of the wetland and the lake to communicate, and the influence on the wetland environment is avoided.
