Description
Technical field
The present invention relates to earth excavation technical field of construction, more particularly to a kind of cubic metre of earth of stage excavation construction party
Method.
Background technique
Earth excavation is engineering initial stage down to the critical process in work progress, and soil and rock are loosened, be crushed, dug
The engineering dug and transported, by rock and soil properties, earthwork evacuation divides earth excavation and rock excavation.Earth excavation is by construction environment
Outdoor, underground is underwater, is divided into open cut, hole is dug and underwater excavation classification.In hydraulic engineering, earth excavation is widely used in field
Ground is smooth and cuts slope, and hydraulic structure (sluice, dam, spillway, powerhouse of hydropower station, pumping plant building etc.) ground excavates, underground
Cavern's (hydraulic tunnel, underground power house, all kinds of adits, vertical shaft and inclined shaft) is excavated, and river, channel, harbour is excavated and dredging, is filled
Material, building stone and aggregate exploitation, the temporay buildings such as cofferdam or stone-laying, the dismounting of concrete structure etc..Soil
Square excavation construction, including loosen, be crushed, digging dress, transport such as is slagged tap at the processes.Rock excavation, except crumbly rock can with ridge buster with
Chisel is split outside method excavation, need to generally be loosened, is crushed in the method for explosion.Artificial and semi-mechanization is excavated, and spade pick, wind are used
The simple tools such as pick, air drill, lift is chosen in cooperation or the means of transport of Simple compact carries out operation, is suitable for small hydraulic project.
The construction of some irrigation and drainage irrigation canals and ditches directly uses ditching machine, can be once-forming, the earthwork evacuation of large and medium-sized hydraulic engineering,
Multi-purpose mechanical construction.
Earth excavation construction work is larger, and the duration is tighter, needs rationally to control every one of working procedure, and existing soil
Square excavation construction method is lack of standardization, not scientific and reasonable enough, and difficulty of construction is big, and construction period is caused to extend.
Therefore above-mentioned technical problem how is solved, there is very much realistic meaning to those skilled in the art.
Summary of the invention
It is an object of the invention to:, not scientific and reasonable enough, construction lack of standardization in order to solve existing earth excavation construction method
The technical issues of difficulty is big, and construction period is caused to extend, the present invention provide a kind of cubic metre of earth of stage excavation construction method.
The present invention specifically uses following technical scheme to achieve the goals above:
A kind of cubic metre of earth of stage excavation construction method, comprising the following steps:
(1) surveying setting-out: according to established plane and elevation control system, boundary stake is released, and is arranged on each boundary
Transverse direction and longitudinal direction controls stake, and every 100m is arranged one, controls stake concreting, and buried depth surveys the side of setting in below ground 20cm
Grid implements construction lofting, and measures the ground elevation and design altitude of grid stake point, if ground elevation is greater than the point
Design altitude be then excavation, be embankment if the design altitude that ground elevation is less than the point, the excavation and filling of each point is high
Degree carries out mark in corresponding control stake with marking pen；
(2) bursting work: one layer of every explosion measures this layer of elevation in time；
(3) it removes surface vegetation: clearing up, excavates excavation section earth's surface organoclay, turf and tree root, and transported to specified abandoning
Tu Chang；
(4) excavation construction: excavating intercepting ditch in advance, and excavation takes stage excavation from top to bottom, excavation when construction cubic metre of earth
Usage mining machine is cut the earth and entrucking, when the gradient is lower than 15 °, bulldozes and incites somebody to action from up to down in certain height using bull-dozer
Soil layer is pushed into low flat region.
Further, in step (1), with marking pen when marking in corresponding control stake, it is if embankment mark
"+" is "-" if excavation mark.
Further, in step (1), in step (1), grid is divided into the lattice of 10m × 10m.
Further, in step (4), if find that soil layer property changes when excavation, arrangement and method for construction need to be modified immediately.
Further, it in step (4), when the earthwork transportation that digs out is to low flat region, when haul distance is in 100m, utilizes
Bull-dozer push, when haul distance is more than 100m, is transported by dumper.
Beneficial effects of the present invention are as follows:
1, unwrapping wire first is being measured to excavation region, construction lofting is being implemented by control stake and grid, to survey
The ground elevation and design altitude of grid stake point out, and embankment and excavation have been marked, it identifies convenient for subsequent construction, then carries out
Each explosion layer is measured when bursting work, the surface vegetation generated in blasting process is cleared up, finally in explosion
Excavation afterwards from top to bottom strictly controlled by carrying out the construction method excavated after measurement work and first explosion in advance by stage excavation
Every one of working procedure is made, standard construction method greatly reduces difficulty of construction, ensure that construction period will not extend, even
Fulfil the duration ahead of schedule.
