Embodiment 2

[0030]Embodiment 2: the earth scraping bar 9 includes a guide wheel 901 and a connecting rod 902, and the four earth scraping bars 9 are installed on the cross bracket 303 through the sleeve sliding sleeve at the top of its tail, and the front end sections of the four earth scraping bars 9 all rotate A guide wheel 901 is installed; a connecting rod 902 is installed on the bushing at the top end of the 9 rear ends of the earth-removing rods everywhere, and the earth-removing rods 9 can be hidden in the synchronous ring 301 along the four supporting square rods on the cross bracket 303. Inside, it is convenient to insert and disassemble inside the concrete pipe 2, so as to avoid protruding out of the support block to cause disassembly obstacles, and the four soil scraping rods 9 can be driven by the rotating shaft 3 to rotate and scrape the soil on the outer eaves of the caisson at the bottom of the concrete pipe 2, so that the concrete The pipe 2 sinks and sinks in the well; fou...

Abstract

The invention discloses a construction device for undrained sinking caissons in complex soil, relates to the technical field of caisson construction equipment, and solves the problem that the existing construction devices mostly rely on the gravity of the concrete pipe itself for sinking, and the concrete pipe itself sinks within a limited gravity The speed is not fast enough, causing the problem of low efficiency of sinking installation. A construction device for an undrained sinking caisson in complex soil, including a base, a lead screw, a motor and a soil removal rod. The base includes a vertical support rod and a top support frame. Two vertical support rods are welded symmetrically on the top of the side plate, and a top support frame is welded and fixed on the top of the two vertical support rods; a crank handle is welded on the top of the two leading screws. The invention can lift and adjust the height of the pressing ring through two screw screws, so that the pressing ring can be suitable for pressing on concrete pipes of different heights, and has wide application.

Description

technical field [0001] The invention relates to the technical field of caisson construction equipment, in particular to a construction device for undrained sinking caissons in complex soil. Background technique [0002] With the expansion of the scale of urban buildings and the enhancement of the awareness of green environmental protection, various infrastructure construction projects, especially the construction projects of sewage collection and transportation pumping stations, are gradually increasing. The caisson is more and more used in the sewage treatment system due to its small excavation volume, relatively small impact on adjacent buildings, good stability, and ability to support large loads. If it is not regular enough, it will deviate from the diameter of the concrete pipe, causing the concrete pipe to not sink smoothly and be installed in the caisson, so a caisson construction equipment that assists the sinking of the concrete pipe is needed. [0003] For example...
