Abstract
The invented construction method includes the following steps: on a ground surface, from its all around, using mechanical cutting machine to groove to a certain depth, then using manual or mechanical method to take out stone material and earth from middle portion of groove, then making reinforced concrete frame between wall and template and depositing concrete to form reinforced concrete retaining wall, then downwards repeating the above-mentioned operation steps so as to implement reinforced concrete pouring engineering from top to bottom layer-by-layer. Said invention is low in cost, simple in construction process, short in construction period, can be safely and quickly used for building underground space.
Description
The present invention relates to a kind of underground space construction method of building, show that especially building the underground space takes the open cut reversed construction method.
At present, to the building underground construction, divide open cut and tunneling two kinds of job practicess substantially both at home and abroad.Built-in in the city proper " people's air defense ", or underground constructions such as " subways ", the conventional open cutting construction method of general employing, urban operating mechanism engineering at first to having built up, open the broken tripe of intestines, boring then, blow out, deslagging, dig basic part always, just carry out at last major project is constructed, after underground major project is built up, waste residue is transported back filled and led up again, also to come disrupted urban operating mechanism full recovery at last, this job practices, it is big to exist investment, the cost height, long construction period is made troubles to citizen's life, good geologic structure is destroyed with good building materials become refuse, weak point such as also be restricted to the construction depth of underground excavation.In the patent disclosure of number of patent application 91103214.2 " a kind of method of building the large-scale underground space ", also exist the construction technology complexity, cost height, shortcoming such as the cycle is long.
The objective of the invention is to solve in the above-mentioned technology and have weak point, and propose a kind of underground space open cutting construction method of building.
The present invention also aims to provide reversed construction method from top to bottom.
The objective of the invention is to realize by following content, begin when slotting certain depth downwards with mechanical cutter all around from ground, middle building stones or the earth that to hold groove with artificial or mechanical means all around successfully take out, carry out between wall and the template after the steel bar concrete water engineering finishes forming, around downwards level carries out, slot, get material, steel bar concrete water again, top-down whole reinforced concrete works is watered finish in layer.
In order to guarantee the mechanical slotting normal operation, the trough that one deck is opened can not be vertical with the trough that last layer is opened, and mechanical cutter is return a bit, stays a small stair, and is simultaneously that the blade of mechanical cutter is more outward-dipping, makes the both sides wall form zigzag.
Indication of the present invention " oppositely " construction is and the rightabout job practices of routine job practices from bottom to top.As building underground construction routinely, be to have dug the tunnel earlier, to carry out post, wall, plate, beam from the basis, tunnel and carry out from bottom to top, this job practices claims " forward " construction method; Otherwise,, be called " reverse " construction method from last and down construct from level to level.
It is low that the present invention has cost, small investment, and construction technology is simple to be grasped easily, and the duration is short, characteristics such as construction safety.
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is one embodiment of the present of invention sectional structure schematic diagram.
Among the figure: trough 7-reinforcing anchor pole that the soil 6-mechanical cutter of 1-ground, 2-steel concrete primary and secondary beam, 3-reinforced concrete floor, 4-steel concrete barricade 5-do not dig is cut
Shown in accompanying drawing, the trough 6 that cut with mechanical cutter downwards 1 both sides from ground, the trough 6 that mechanical cutter is cut outwards is a steel concrete shelves wall 4, steel concrete primary and secondary beam 2 and reinforced concrete floor 3 that each level is arranged between steel concrete shelves wall 4, if the wall of the trough 6 that mechanical cutter is cut finds to have situations such as crack, fragmentation, reinforce the soil 5 that does not dig with reinforcing anchor pole 7.
Claims (2)
1. open-cut reversed construction method for rehabilitating underground space, it is characterized in that (1) begins when slotting certain depth downwards with mechanical cutter all around from ground, middle building stones or the earth that to hold groove with artificial or mechanical means all around successfully take out, carry out steel bar concrete water to forming between wall and the template, form steel concrete barricade (4), around downwards level carries out, slot, get material, steel bar concrete water again, top-down whole reinforced concrete works is watered finish in layer.
2. a kind of open-cut reversed construction method for rehabilitating underground space according to claim 1 is characterized in that mechanical cutter returns a bit, stays a small stair, and is simultaneously that the blade of mechanical cutter is more outward-dipping, makes the both sides wall form zigzag.
