(3), riprap foundation
At pump house, intend sinking place and carry out foundation trench excavation and silt displacement, jackstone in foundation trench then, the riprap foundation that is 0.5～6m by the smooth rear height of formation of jackstone, piece stone diameter is Ф 50～200mm, the porosity after throwing is more than 40%;
(4), caisson connects height
Above-mentioned the first prefabricated absolute altitude section concrete caisson transportation by driving to pump house is intended to sinking place, then carry out on the water concrete caisson and connect high construction by pump house structure, and in concrete caisson the interim ruggedized construction being formed by steel post and cross binding that arranges, to improve the stabilized structure of concrete caisson when the sinking;
(5), the sinking of caisson
The setting-out of annotating in the above-mentioned concrete caisson connecing after height arranges concrete caisson sinking interim ballast on riprap foundation and in caisson, then drains the setting-out in concrete caisson;
(6), top out and equipment is installed
Proceed the construction that connects height and pump house structure of concrete caisson, until pump house tops out, then water pump and outlet conduit system thereof are installed in pump house structure;
(7), remove interim ruggedized construction
Remove the ruggedized construction and the steel that are arranged in concrete caisson seals up a door temporarily.
It is low that the present invention compared with prior art has construction costs, easy construction, and the duration is short, and workmanship is reliable, little to surrounding environment influence, is especially applicable to batholith regional Construction dock pump house.
