Description
Technical field
The present invention relates to the device and method of deep foundation ditch earthwork transportation in a kind of construction work.
Background technology
At present, when the deep foundation ditch reverse construction, the key of restriction duration is a cubic metre of earth travelling speed.Most of contrary working method engineering adopts high-front shovel, and crawler belt grab bucket shovel machine or straddle truck directly are unearthed from the shoveling hole.The long-armed digging machine on limit, hole or crawler belt grab bucket shovel machine need turn round operation when promoting dress soil owing to be unearthed, and needs bigger running space, and big machinery and vehicle need be gone up floor.The mode of more than being unearthed mainly is fit to have the basement excavation of annex, perhaps the half contrary engineering of doing.
When overground part take up an area of with under ground portion take up an area of about the same when big because the restriction of first floor floor height, have only when under ground portion cut the earth finish after, just can carry out the construction of overground part, very big to the duration influence like this.
Summary of the invention
The invention provides a kind of reverse construction earthwork vertical transferring apparatus and method, solve that existing earthwork construction shoveling inefficiency, digging machine are huge, shoveling cost height, the technical problem that can not carry out the superstructure construction simultaneously.
For achieving the above object, the present invention adopts following technical scheme:
This reverse construction earthwork vertical transporting method, it adopts the instrument of the belt-type conveyer belt of merogenesis as deep foundation ditch earthwork transportation, conveyer belt passes from the reservation hole of each floor plate, and the earthwork is directly transported on the ground tipping truck through conveyer belt, and concrete construction sequence is as follows:
Step 1: at first carry out the construction of space enclosing structure, pile foundation and the intermediolateral column in deep foundation pit construction place;
Step 2: the open cut earthwork on construction ground, the construction of clay model method
± 0The floor of layer,
± 0Reserve the hole on the floor of layer, arrange the conveyer belt of the first floor, will
± 0The earthwork that layer excavates
± 0Layer is transported on the tipping truck on ground through conveyer belt;
Step 3: when
± 0The structural strength of floor plate reaches at 100% o'clock, removes
± 0The floor plate is reserved the template and the cleaning at place, hole, the hole is local cuts the earth downwards from reserving, reserve lower floor's digging face, to the negative one deck conveyer belt of the oblique continued access of negative one deck, the earthwork that divides the negative one deck of section tunneling, horizontal spreading conveyer belt is to the work plane of cutting the earth, to be transported on the tipping truck on ground in the earthwork that negative one deck excavates, simultaneously, with the floor of the negative one deck of clay model method construction, floor at negative one deck is reserved the hole, construction F2/B2 floor;
Step 4: when the floor slab structure intensity of negative one deck reaches 100%, remove the floor of negative one deck and reserve hole place's template and cleaning, toward the negative two layers of conveyer belt of negative two layers of oblique continued access, divide the section tunneling negative two layers of earthwork, horizontal spreading conveyer belt will be transported on the tipping truck on ground in the earthwork of negative two layers of excavation to the work plane of cutting the earth, simultaneously, the floor that the construction of clay model method is negative two layers is reserved the hole at negative two layers floors, and construction is three floor plates on the ground;
Step 5: repeat above-mentioned steps three to step 4, until being excavated to the basement bottom board place.
The reverse construction earthwork vertical transferring apparatus that described method adopted, form by the independent segmented belt-type conveyer belt head and the tail continued access that is obliquely installed, has one section conveyer belt at least at each floor, described belt-type conveyer belt comprises motor, running roller, running roller pedestal, belt, conveyer belt frame and elevating hopper, and elevating hopper is positioned at the afterbody of belt-type conveyer belt.
The angle of inclination of described conveyer belt is less than 19 degree.
The inclination conveyer belt of described each floor and the continued access of horizontal spreading conveyer belt.
Reverse construction earthwork vertical transporting method of the present invention and device can be according to total earth volumes of basement, and the budget shoveling duration calculates the amount of being unearthed every day, and the individual layer area is divided into some unearthed districts, and each district sets up one to overlap independently conveyer belt vertical transit system.
The conveyer belt vertical transit system is constituted jointly by the conveyer belt of independent merogenesis, and every joint length does not wait from 8 meters-20 meters, according to floor height, the openings position flexible arrangement, box out on the floor is that 2 meters wide * 4 are meter long just enough, but double as ventilation hole, hole is placed ladder and done personnel's passage up and down.
Soil in bulk is evenly distributed on very long being with, and is little to the pressure of each strong point, do not have impact load, do not need the extra in addition floor design of reinforcement that increases.
Compared with prior art the present invention has following beneficial effect:
1. because conveyer belt can directly arrive the shoveling work plane of basement by spreading, excavator can with the earthwork of excavating directly overturning on conveyer belt, therefore, do not need basement to turn over to refute digging machine to turn over haul volume, reduced the process of cutting the earth and lightering.Can increase substantially shoveling efficient.
2. the required dimension of opening of conveyer belt is less, and is favourable to horizontal support structure.
3. adopt the conveyer belt vertical transport to replace
± 0The large-scale lifting earth loader tool such as the straddle truck of the big rotary space of the needs on the floor, long-armed digging machine etc.Therefore, the above and below ground structure can be constructed simultaneously, can effectively accelerate the duration.
4. the power owing to conveyer belt is electricity, and a large amount of digging machines of former method are diesel, and the environmental protection energy-saving and emission-reduction have also been produced sizable benefit.
5. after the employing carousel transmission scheme, the muck haulage vehicle is not gone up floor, and beam slab does not need to strengthen design, has reduced amount of reinforcement.
6. but the present invention's overground part and under ground portion are constructed simultaneously, effectively increase the earth volume of single vertical transport, effectively improve shoveling efficient, reduce digging machine, reduce the shoveling cost, the influence that underground excavation and construction is constructed simultaneously to superstructure eases down to minimum degree, has shortened the duration significantly.
