Description
Technical field
The present invention relates to a kind of job practices of formwork erecting structure, especially, relate to a kind of job practices of underground structure side wall single side formwork.
Background technology
Along with the expansion of China's building field to the underground space, also towards super dark, super large, complexity, multi-form future development, construction technology more sophisticated, difficulty of construction progressively increase deep-foundation pit engineering.The significant progress that the appearance of diaphragm wall and inner support support system brings to deep-foundation pit engineering, also construction has proposed higher technical requirements to side wall simultaneously, especially the concrete side of Metro Station Structure side wall one-time-concreting amount is larger, the side wall template can only adopt single side formwork, if adopt that traditional full framing system exists that the side wall concrete builds that difficulty, maintenance are difficult, template and the problem such as the support turn around time is long, materials are many.Because expire setting up of hall support body, other operation can't be constructed in the foundation ditch simultaneously.For under the prerequisite that guarantees foundation ditch safety and construction quality, add the construction of express bus stop main body side wall, reduce the side wall template construction to the impact of other operation, need to seek a fast and efficiently job practices, should guarantee construction quality, simplify simultaneously construction technology, saved construction space, accelerated speed of application.
Therefore underground structure side wall single side formwork is necessary to design a kind of new structure and job practices.
Summary of the invention
Main purpose of the present invention is to propose a kind of new ground lower side wall unilateral formwork supporting structure and job practices.
The present invention has disclosed a kind of underground structure side wall single side formwork job practices, comprises the steps:
Installation form, this template comprise the first side and the second side, and wherein the first side is near a diaphragm wall;
An end that draws water-proof bolt is fixed on the diaphragm wall by connecting reinforcement;
Punch in template, will the other end that draw water-proof bolt be passed from template the first side, and pass with nut in the second side of template and to fix;
According to stressed needs a plurality of such formwork erecting structures are installed;
Build side wall concrete, finish the construction of underground structure side wall single side formwork.
Preferably, in described diaphragm wall excavation bar planting hole, connecting reinforcement implanted in the bar planting hole be fixed.
Preferably, described diaphragm wall is carried out the part pick cutter, expose main muscle, be fixed with the connecting reinforcement welding.
Preferably, on the second side of described template secondary joist and main joist are installed successively.
Preferably, three type cards are installed between the main joist of the second side of described template and the nut and are further compressed main joist.
Preferably, described the first side place of drawing water-proof bolt to press close to template is welded with the Template Location muscle.
Preferably, connecting reinforcement with to drawing the water-proof bolt diameter identical.
The invention has the beneficial effects as follows: a large amount of engineering quantitys of setting up that reduce full hall support body or trivet, for other operation construction provides larger work plane, reduced material cost, effectively shortened the construction period, guarantee simultaneously side wall construction quality and safety.
Description of drawings
Fig. 1 is the schematic diagram of underground structure side wall formwork one embodiment of the present invention;
Fig. 2 is the schematic diagram of another embodiment of underground structure side wall formwork of the present invention.
The specific embodiment
Describe underground structure side wall unilateral formwork supporting structure of the present invention in detail referring to accompanying drawing.
As shown in Figure 1 and Figure 2, this underground structure side wall unilateral formwork supporting structure comprises template 12, the diaphragm wall 1 that template 12 is contiguous, connecting reinforcement 15 with to drawing water-proof bolt 16.
In the present embodiment structure, 121 places, the first side of drawing water-proof bolt 16 to press close to template 12 are welded with Template Location muscle 8, with further locating template 12.
Preferably, secondary joist and main joist are installed, with further reinforcing template intensity on template 12 second sides.
The following a kind of construction sequence that further describes this underground structure wall unilateral formwork supporting structure in conjunction with Fig. 1, Fig. 2.
At first that space enclosing structure construction in the boundary of works area is complete, and satisfy the excavation requirement;
Earth excavation is to predetermined absolute altitude;
Measure unwrapping wire.According to the spacing of side wall thicknesses and formwork system design connecting reinforcement 15, the position that connecting reinforcement 15 is installed is thrown in to diaphragm wall face 1;
According to throwing in to the position of 1 upper connecting reinforcement 15 of diaphragm wall, in diaphragm wall, excavate bar planting hole 14 and fill the bar planting agent, above-mentioned connecting reinforcement 15 is implanted in this bar planting hole 14, and in the present embodiment, implantation depth is 15d (d is the connecting reinforcement diameter);
Connecting reinforcement 15 is welded an end that draws water-proof bolt 16 with above-mentioned, and the present embodiment is single-sided welding, and fusion length is 10d;
Colligation side wall reinforcing bar (not shown);
Installation side wall form 12, and according to the position of drawing water-proof bolt 16 to penetrate is punched in template 12, to not pass from the first side 121 of template 12 with the other end that connecting reinforcement 15 welds drawing water-proof bolt 16, and pass in the second side 122 of template 12, fixing with nut 11, complex root secondary joist 13 is installed on template 12 second sides 122, and the direction vertical with secondary joist 13 installed two main joists 9 on template 12, secondary joist 13 and main joist 9 all with to drawing water-proof bolt 16 vertical, in the present embodiment, secondary joist 13 is selected 100 * 100 flitches, spacing is not more than 200mm, can directly be fixedly installed on the template 12 with the nail (not shown), main joist 9 is selected 48 pairs of steel pipes of φ, vertical spacing is not more than 500mm, main joist 9 is installed on drawing the both sides of water-proof bolt 16, be between nut 11 and the secondary joist 13, nut 11 main joist 9 that can directly be fixedly clamped, or as in the present embodiment, the three type cards 10 that perforation is arranged in the middle of increasing in the middle of main joist 9 and the nut 11, further compress main joist 9, fixing with nut 11.
