Abstract

The invention relates to a lining wall concrete placement top-down method based on an underground diaphragm wall. The lining wall concrete placement top-down method comprises the following steps: (1) the underground diaphragm wall is constructed; (2) a foundation floor slab is constructed; (3) an upper floor slab is constructed; (4) a formwork is erected, an upper layer of lining wall concrete is poured, a steel pipe is pre-buried every 2-3 meters in the upper layer of lining wall concrete, and the lower end of each pre-buried steel pipe is arranged on the top of an inverted groove in the lower portion of an upper lining wall which is formed in a pouring mode; (5) a lower lining wall formwork is erected, wherein the formwork is directly connected with the upper lining wall from the bottom surface of the foundation floor slab and is mounted in a closed mode, pump truck concrete delivery pipes used for pouring a lower layer of lining wall concrete are inserted in the pre-buried steel pipes to conduct pouring continuously, the concrete is compacted by means of vibration, a micro-expanding agent is added into the concrete, and then pouring of the lining wall concrete is completed. The lining wall concrete placement top-down method based on the underground diaphragm wall is simple in operation process, can sufficiently guarantee that the concrete poured in the lining walls later is compact, accelerates construction progress, and improves construction efficiency.

Description

The contrary method of doing of inwall pouring concrete based on diaphragm wall
Technical field
The invention belongs to inwall pouring concrete field, the contrary method of doing of especially a kind of inwall pouring concrete based on diaphragm wall.
Background technology
In building field deep foundation pit construction, often adopt diaphragm wall as space enclosing structure, and side inner lining construction wall become the exterior wall of underground construction within it.Sometimes inwall and underground structure adopt contrary sequence method to construct, the method of inwall pouring concrete is normally: below basic bottom application work complete after, install wall side form, between the inwall that template and top have poured, stay and establish certain space, template is outwards tiltedly chosen, do funnel, then carry out pouring concrete.This method pouring technology is complicated, and the concrete stretching out outside wall will cut after form removal, is cast in as placed concrete junction simultaneously has the blind area of vibrating by this method, has air to be difficult for discharging, and forms space, causes infiltration phenomenon.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of inwall pouring concrete based on diaphragm wall the contrary method of doing, this inwall pouring concrete is simple to operate against making method, can effectively solve the contrary uncompacted problem of cast of doing of inwall, shortened the engineering time, accelerate construction speed, improved efficiency of construction.
The present invention solves its technical problem and is achieved through the following technical solutions:
The contrary method of doing of inwall pouring concrete based on diaphragm wall, its this cast is contrary to be comprised the steps: as method
(1), that construction of diaphragm wall is complete;
(2), basic floor slab construction is complete;
(3), upper strata floor slab construction is complete;
, install upper strata inwall mould bases, cast upper strata inwall concrete, and in this upper strata inwall concrete at interval of the pre-buried steel pipe of 2-3 rice, the lower end of every embedded steel tube is arranged at the inverted groove top of watering inwall bottom, upper strata;
(5), install lower floor's inwall mould bases, this mould bases from basic soffit directly and upper strata inwall join, adopt closed installation, the concrete pump truck elephant trunk of cast lower floor's inwall inserts from embedded steel tube, pour into a mould continuously, constructor transfers vibrating head by within the scope of concrete jolt ramming , lower floor's inwall top 150mm from the reserved pre-buried steel mouth of pipe, in the concrete of cast, add micro-expanding agent, inwall pouring concrete is complete.
And described embedded steel tube comprises lower vibrating spear steel pipe, exhaust steel pipe and lower grey steel pipe, this lower vibrating spear steel pipe, exhaust steel pipe and lower grey steel pipe are alternately arranged in the inwall concrete of upper strata.
And described micro-expanding agent is UEA micro-expanding agent.
Advantage of the present invention and beneficial effect are:
The present invention adopts in the inwall concrete of upper strata at interval of the pre-buried steel pipe of 2-3 rice, the lower end of every embedded steel tube is arranged at the mode at the inverted groove top of watering inwall bottom, upper strata, adopt closed installation, the concrete pump truck elephant trunk of cast lower floor's inwall inserts from embedded steel tube, pour into a mould continuously, constructor transfers vibrating head by concrete jolt ramming from the reserved pre-buried steel mouth of pipe, within the scope of lower floor's inwall top 150mm, in the concrete of cast, add micro-expanding agent, the method operating procedure is simple, can fully guarantee the closely knit of pouring concrete after inwall, accelerated construction speed, improved efficiency of construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
The contrary method of doing of inwall pouring concrete based on diaphragm wall, its this cast is contrary to be comprised the steps: as method
(1), that diaphragm wall 5 constructions are complete;
(2), basic floor 6 constructions are complete;
(3), floor 7 constructions in upper strata are complete;
, install upper strata inwall mould bases, cast upper strata inwall concrete 1, and in this upper strata inwall concrete at interval of the pre-buried steel pipe 2 of 2-3 rice, the lower end of every embedded steel tube is arranged at the inverted groove top of watering inwall bottom, upper strata; Embedded steel tube comprises lower vibrating spear steel pipe, exhaust steel pipe and lower grey steel pipe, and this lower vibrating spear steel pipe, exhaust steel pipe and lower grey steel pipe are alternately arranged in the inwall concrete of upper strata.
(5), install lower floor's inwall mould bases 4, this mould bases from basic soffit directly and upper strata inwall join, adopt closed installation, the pump truck elephant trunk of cast lower floor inwall concrete 3 inserts from embedded steel tube, pours into a mould continuously, and constructor transfers vibrating head by concrete jolt ramming from the reserved pre-buried steel mouth of pipe, within the scope of lower floor's inwall top 150mm, in the concrete of cast, add micro-expanding agent, micro-expanding agent is UEA micro-expanding agent, and inwall pouring concrete is complete.
The present invention adopts closed installation to save template outwards tiltedly to be chosen, done the operation that funnel is poured into a mould and then cut, and the financial resources that use manpower and material resources sparingly improve efficiency of construction and construction quality.Adopt embedded steel tube to carry out lower ash, exhaust, vibrate, improved pouring concrete quality, increased concrete compaction degree, improved construction quality.
