Abstract
The utility model discloses a subway construction engineering construction shaft belongs to the subway construction field. The utility model discloses subway construction engineering construction shaft, including the well body, the periphery of the well body sets up the stock, the transverse section of the well body is the ellipse, well body top is equipped with the fore shaft collar tie beam, the fixed hoisting device that sets up on the fore shaft collar tie beam, well body bottom is equipped with the pit. Horizontal steel shotcrete and angle brace can be cancelled to oval shaft, the demand greatly reduced of grid reinforcing bar simultaneously, very big reduction construction cost, the horizontal steel shotcrete of cancellation is convenient for the portal crane and is slagged tap, improves the efficiency of construction, reduces the construction risk.
Description
Technical field
The present invention relates to subway construction field, particularly a kind of subway construction engineering construction vertical shaft.
Background technology
Along with the development of subway construction, especially in Station construction, construction shaft is more and more applied.The vertical shaft adopted in current subway construction is mostly rectangle vertical shaft, and must set up when section is comparatively large or foundation ditch is darker and support firmly, work progress is too loaded down with trivial details, and temporary support structure affects greatly follow-up construction.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of subway construction engineering construction vertical shaft being beneficial to construction, saving material, efficiency of construction be provided, reduce construction risk.
Technical scheme of the present invention is:
A kind of subway construction engineering construction vertical shaft, comprise well body, the periphery of described well body arranges anchor pole; The lateral cross section ovalize of described well body; Described well body top is provided with fore shaft collar tie beam, is provided with pit bottom described well body.
Preferably, described fore shaft collar tie beam is fixedly installed lifting appliance.
Preferably, described well body is formed by being filled with concrete steel grating.
Preferably, described lifting appliance comprises portal frame and is arranged on the electric block on portal frame.
Further, described portal frame periphery adopts dividing plate to close.
Preferably, the long axis length of oval well body is 1.3-2 times of minor axis length.
Research calculates first internal force of rectangle vertical shaft and oval vertical shaft, and result is as shown in table 1;
First internal force comparison sheet of table 1 rectangle vertical shaft and oval vertical shaft
Can find out by just propping up internal force result: under identical loading condition, traditional rectangular vertical shaft corner hogging moment concentration phenomenon, its well bore hogging moment maximum value is 3.5 times of oval vertical shaft, and well bore positive bending moment maximum value is 3 times of oval vertical shaft.Its impact is exactly that grid reinforcing bar demand area is double, and needs increase by one Horizontal steelwork bracing to resist long limit positive bending moment in the middle part of vertical shaft, and bight need increase angle brace to share bight hogging moment.And load can be converted into axle power by oval vertical shaft stress system, make full use of concrete compressive strength.Under the prerequisite significantly reducing bending and shearing, improve axle power, favourable to arrangement of reinforcement control critical eigenvalue.
With form of fracture 12m × 8m, the degree of depth is that the vertical shaft of 26m is analyzed:
Adopt ellipsoidal structure form of fracture to compare traditional rectangular cross section form and reduce concrete angle brace 60, each cost 612 yuan, amount to cost-saving 36720 yuan.Bracing members 15 in the middle of reducing, every root cost 1095 yuan, amounts to cost-saving 16425 yuan.Amount to cost-saving 53145 yuan.
Owing to eliminating the fabrication and installation time of heel brace and middle bracing members, the engineering time of often circulating reduces 14 hours, and vertical shaft amounts to point 26 circulation constructions, saves time altogether 364 hours about 15 days.
To Construction of Silo takes up an area little, reduces the impact on surrounding enviroment and resident to greatest extent.
Oval vertical shaft can cancel Horizontal steelwork bracing and angle brace, and the demand of grid reinforcing bar reduces greatly simultaneously, greatly reduces construction cost, cancels Horizontal steelwork bracing and is convenient to straddle truck and slags tap, improve efficiency of construction, reduce construction risk.
Beneficial effect of the present invention is:
Oval vertical shaft can cancel Horizontal steelwork bracing and angle brace, and the demand of grid reinforcing bar reduces greatly simultaneously, greatly reduces construction cost, cancels Horizontal steelwork bracing and is convenient to straddle truck and slags tap, improve efficiency of construction, reduce construction risk.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
