Abstract
The invention relates to a lining wall concrete pouring inversing method based on a UEA micro-expanding agent. The method includes the following steps of firstly, completing underground continuous wall construction; secondly, completing foundation floor construction; thirdly, completing upper floor construction; fourthly, erecting a formwork, pouring upper layer lining wall concrete, and embedding steel pipes in the upper layer lining wall concrete, wherein the interval of the steel pipes ranges from 2 m to 3 m, and the lower ends of the embedded steel pipes are arranged on the tops of reverse grooves in the lower portion of an upper layer lining wall where pouring has been conducted; fifthly, erecting a lower layer lining wall formwork, directly connecting the formwork with the upper layer lining wall from the bottom face of a foundation floor, adopting closed type installation, inserting a pumper concrete conveying pipe pouring lower layer lining wall concrete into each embedded steel pipe, unceasingly conducting pouring, compacting the concrete through vibration, adding the micro-expanding agent, and completing pouring of the lining wall concrete. The method is simple in operation process, compactness of the concrete poured to the rear portion of the lining wall can be fully ensured, the construction progress is accelerated, and the construction efficiency is improved.
Description
The application be number of patent application be 201310612772.6, patent name is continuous based on underground
The inwall concrete cast of wall is inverse makees method, the divisional application of filing date 2013.11.26.
Technical field
The invention belongs to inwall concrete cast field, especially a kind of based on UEA micro-expanding agent
The cast of inwall concrete inverse make method.
Background technology
In building field deep foundation pit construction, through frequently with diaphram wall as building enclosure, and
Within it inner lining construction wall becomes the exterior wall of underground engineering.Sometimes inwall uses with underground structure
Contrary sequence method is constructed, and the method for inwall concrete cast is typically: basis bottom application work below
After complete, install to stay between the inwall that wall side form, template and top have poured and set certain space,
Template is the most tiltedly chosen, does funnel, then carry out concrete cast.This method is poured into a mould
Complex process, stretches out the concrete outside wall and to cut after form removal, be cast in by this method simultaneously
There is blind area of vibrating in novel concrete junction, has air to be difficult to discharge, form space, cause infiltration
Phenomenon.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of based on UEA microdilatancy
The inwall concrete cast of agent is inverse makees method, and the cast of this inwall concrete is inverse makees method operation letter
It is single, it is possible to efficiently solve inverse work of inwall and pour into a mould uncompacted problem, shorten the engineering time,
Accelerate construction speed, improve efficiency of construction.
The present invention solves its technical problem and is achieved through the following technical solutions:
The cast of a kind of inwall concrete based on UEA micro-expanding agent is inverse makees method, and its this cast is inverse
Comprise the steps: as method
(1), that construction of diaphragm wall is complete；
(2), basis floor slab construction is complete；
(3), upper strata floor slab construction is complete；
(4), install upper strata inwall mould bases, pour into a mould upper strata inwall concrete, and in this upper strata
At interval of the pre-buried steel pipe of 2-3 rice in chemise concrete, the lower end of every embedded steel tube is arranged at
Water the inverted groove top of inwall bottom, upper strata；
(5), installing lower floor's inwall mould bases, this mould bases is direct and upper strata liner from basis soffit
Wall connects, and uses closed installation, the pump truck concrete delivery pipe of cast lower floor inwall concrete
Insert from embedded steel tube, be carried out continuously cast, under workmen is from the reserved pre-buried steel mouth of pipe
Put vibrating head by concrete jolt ramming, in the range of lower floor's inwall top 150mm, the coagulation of cast
Adding micro-expanding agent in soil, inwall concrete is poured.
And, described embedded steel tube includes lower vibrating spear steel pipe, aerofluxus steel pipe and lower ash steel
Pipe, this lower vibrating spear steel pipe, aerofluxus steel pipe and lower ash steel pipe are alternately arranged at upper strata inwall
In concrete.
And, described micro-expanding agent is UEA micro-expanding agent.
Advantages of the present invention and having the beneficial effect that
The present invention uses in the inwall concrete of upper strata at interval of the pre-buried steel pipe of 2-3 rice, every
The lower end of embedded steel tube is arranged at the mode at the inverted groove top watering inwall bottom, upper strata, adopts
Using closed installation, the pump truck concrete delivery pipe of cast lower floor inwall concrete is from embedded steel tube
Middle insertion, is carried out continuously cast, and workmen transfers vibrating head from the reserved pre-buried steel mouth of pipe will
Concrete jolt ramming, in the range of lower floor's inwall top 150mm, adds micro-in the concrete of cast
Extender, the method operating procedure is simple, can fully ensure that the closely knit of pouring concrete after inwall,
Accelerate construction speed, improve efficiency of construction.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following example simply describe
Property, it not determinate, it is impossible to limit protection scope of the present invention with this.
The cast of a kind of inwall concrete based on UEA micro-expanding agent is inverse makees method, and its this cast is inverse
Comprise the steps: as method
(1), diaphram wall 5 is constructed complete；
(2), basis floor 6 is constructed complete；
(3), upper strata floor 7 is constructed complete；
(4), install upper strata inwall mould bases, pour into a mould upper strata inwall concrete 1, and in this upper strata
At interval of the pre-buried steel pipe 2 of 2-3 rice in chemise concrete, the lower end of every embedded steel tube is arranged at
Water the inverted groove top of inwall bottom, upper strata；Embedded steel tube includes lower vibrating spear steel pipe,
Aerofluxus steel pipe and lower ash steel pipe, this lower vibrating spear steel pipe, aerofluxus steel pipe and lower ash steel pipe are handed over
