Abstract
The invention discloses an installation method of a caisson. The method is technically characterized by comprising the steps that firstly, a base groove of the caisson is treated to enable the caisson to be effectively connected with a foundation; secondly, after the base groove of the caisson is formed, the position foundation needing to be treated is filled with or leveled with bagged sand according to actual conditions on a construction site, and caisson primary positioning and initial installation are carried out; thirdly, caisson jacking and leveling work is performed, and the caisson is jacked up to be disengaged from a foundation bed; fourthly, the periphery of the caisson is temporarily plugged; fifthly, a booster pump is adopted for carrying out grouting treatment on the bottom of the caisson through a grouting hole preserved in the bottom of the caisson, a caisson foundation is laid after forming, a jacking mechanism is disassembled after mortar forms the strength, and grouting treatment is carried out inside a jacking pipeline; sixthly, a temporary plugging structure on the periphery of the caisson is dug out, and caisson installation is finished. By the adoption of the technical scheme, the construction mechanization degree is high, construction efficiency is improved, the construction cost is reduced, influences on the environment are reduced, and operation safety and environmental protection capability are improved.
Description
Technical field
The present invention relates to Caisson Placing Construction technology field, specifically a kind of installation method of caisson.
Background technology
Existing Caisson Placing Construction method, first do rubble-mound foundation, rear installation caisson, need to dredge to bedding, jackstone, strong rammer, thick flat, thin equality, there is operation intensity large, large to surrounding environment influence, part operation needs diver's diving operation, has the more high deficiency of construction operation inefficiency and danger.
Summary of the invention
Object of the present invention, solves the problem existing in above technology exactly, and a kind of caisson and installation method thereof are provided for this reason.
An installation method for caisson, the first step, carries out the processing of caisson foundation trench, makes caisson and ground effective connection;
Second step, after the moulding of caisson foundation trench, adopts packed sand according to the actual conditions of job site, basis, need position to be processed to be filled and leveling, carries out the location of caisson and just installs;
The 3rd step, carries out jacking and the leveling work of caisson, and caisson jack-up and bedding are departed from;
The 4th step, carries out temporary plugging to caisson surrounding;
The 5th step, adopts force (forcing) pump by the reserved grout hole in caisson bottom, and grouting treatment is carried out in caisson bottom, and paving caisson foundation after forming, after mortar forms intensity, removes lifting body, and jacking pipe interior is carried out to grouting treatment;
The 6th step, digs out the temporary plugging structure of caisson surrounding, completes the installation of caisson.
Further, describedly caisson surrounding is carried out to temporary plugging adopt piece stone and bagged concrete.
Advantage of the present invention:
1, installation method of the present invention is for caisson is first installed, and rear employing is filled with afterwards the mode of mortar and carried out bedding construction, thereby exempts bedding jackstone, strong rammer, thick flat, thin equality working procedure;
2, this installation method mechanization of building operation degree is high, reduces manual work amount, improves efficiency of construction, reduces construction cost;
3, reduce the impact on environment, improve operational security and capability of environmental protection.
Specific embodiment
