Description
Technical field
The present invention relates to the construction method of fender post, in particular to a kind of construction method of subway station occlusion fender post.
Background technique
Subway station is built, the construction method of existing foundation pit are as follows: will need generally all in underground so needing to carry out foundation pit digging
The position digged pit carries out scribing operation, fender post is poured on foundation pit periphery, outside the landslide or foundation pit for preventing foundation pit side-wall
Infiltration inside lateral foundation pit.
In order to improve the intensity of fender post, a kind of existing occlusion fender post allows two neighboring concrete column to be formed irregular
Occlusive state improves the support strength of fender post.
The construction method of existing occlusion fender post are as follows: template is fixed on the ground, then pours and leads on the outside of template
Wall drills in the portion within the walls that leads, and two adjacent drillings intersect, and alternately casting concrete stake, allows adjacent in drilling
Two concrete-piles be mutually twisted, formed interlocking pile, improve the intensity of fender post.
Above-mentioned the shortcomings of the prior art is: pour lead wall during, need using template, existing skill
Template in art includes the plate body of arc and the support bracket for connecting opposite two plate bodys and adjacent plate body, plate body are
Metal is made, and quality is larger, due to being that bolt is fixedly connected between support bracket and plate body, dismounts or carry inconvenience, in turn
Influence construction efficiency.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to: a kind of occlusion fender post in subway station is provided
Construction method, by using easy disassembly template so that improve construction efficiency the advantages of.
Above-mentioned technical purpose is achieved through the following technical solutions, a kind of construction party of subway station occlusion fender post
Method includes the following steps, step 1: scribing line；Step 2: leading wall production；Step 3: drilling pours, the production method for leading wall is
Guide wall is first dug, simultaneously fixed form is put in guide wall, and in the assembling reinforcement of template two sides, is then poured on reinforcing bar mixed
Solidifying soil, the template include the first noumenon, second ontology adjacent with the first noumenon, the third ontology opposite with the first noumenon,
The connection for being detachably fixed connection the first noumenon and the second ontology is provided between the first noumenon and the second ontology
The alignment component for being aligned the first noumenon Yu third ontology is provided on part, the first noumenon and the third ontology.
Construction can be allowed more accurate through the above technical solutions, first carrying out scribing line, the production for leading wall can facilitate drilling
The use of mechanical equipment in casting process, mechanical equipment operates on leading wall can be reduced borehole sidewall in boring procedure and is set by machinery
The standby risk for rolling landslide, can more accurately the position of drilling be drawn a circle to approve by leading wall by template construct, allow lead wall according to
Scheduled shape is poured.The first noumenon and the second ontology are detachably connected by template by connector, facilitate template
Transport, installation and disassembly, and then reduce transport and installation time, so as to improve construction efficiency.
Further, the connector includes being fixedly connected on the first noumenon close to the first connection ring of the second ontology side
And it is fixedly connected on second connection ring of second ontology close to the first noumenon side, pass through first connection ring and described
Second connection ring is plugged with connecting rod, and connector further includes for the first connection ring and the second connection ring to be fixed on connecting rod
Plugboard.
Through the above technical solutions, connecting rod, which is inserted into connection ring, to connect the first noumenon and the second ontology
It connects, by plugboard that the first noumenon and the second ontology fixed operation is convenient, the mode of grafting can allow connection more convenient,
When dismantling template, it is only necessary to extract connecting rod out of the first connection ring and the second connection ring after extracting plugboard
The first noumenon is separated with the second ontology, it is easy to operate.
Further, it is fixedly connected in connecting rod in the middle part of the plugboard, the plugboard two sides are plugged on the respectively
On one ontology and the second ontology.
Through the above technical solutions, the positional relationship of the fixed two neighboring stencil body of connecting rod, it can by plugboard
Fix the relative angle of two stencil bodies, it is only necessary to which the fixation of two templates of operation can be completed in Plug Action, easy to operate.
Further, the application method of connector are as follows: the first noumenon and the second ontology are placed in guide wall, by first
Connection ring is opposite with the annular distance of the second connection ring to sequentially pass through the first connection ring and the second connection ring for connecting rod afterwards, and will insert
Fishplate bar is inserted into the first noumenon and the second ontology.
Through the above technical solutions, capableing of the fixation of more convenient pair of body position.
Further, the alignment component include be respectively fixedly connected on the first noumenon and third ontology to penetrating laser
Sensor includes being fixed on the first noumenon close to the transmitting terminal of third ontology side and being fixed on third to laser sensor is penetrated
Ontology is electrically connected with indicator light on the receiving end of the first noumenon side, laser-correlation sensor.
Through the above technical solutions, can determine the first noumenon and third ontology face when opposite type sensor face, it can
Facilitate the position of determining third ontology, in operating process, the line of demarcation that first step generates to the layout line put the first noumenon and
Third ontology, by penetrate laser sensor can facilitate to third body position relationship determine operation it is more convenient, more
Precisely, it can conveniently see whether that laser sensor is aligned by the setting of indicator light.
Further, the alignment component includes two pairs to penetrating laser sensor altogether, and is electrically connected with indicator light.
Through the above technical solutions, separate according to what two points make a line, one is not accurate enough to the setting of laser sensor,
Two laser sensors are aligned to illustrate the first noumenon and third ontology face, can be more accurate judge
And adjustment.
Further, the spacing for measuring the first noumenon Yu third ontology is provided between the first noumenon and third ontology
From measuring piece.
Through the above technical solutions, by the setting of measuring piece can control between the first noumenon and third ontology away from
From, and then control and lead the distance between wall and drilling, it is more convenient during drilling construction.
Further, the measuring piece includes the casing being rotatably connected on the first noumenon, and is rotatably connected on second
Ontology and the scale bar being inserted on the first noumenon.
Through the above technical solutions, scale bar is inserted into casing, after then the first noumenon and third ontology are well placed,
Adjusting the distance between the first noumenon and third ontology can be facilitated by observing scale bar, it is easy to operate.
The present invention has following technical effect that in summary
1, the transport of template can be facilitated by being detachably connected for template, be made since template is generally metal, transport and
Carrying needs manpower or material resources relatively more, can facilitate the carrying of template by the card disassembly of template, during wall is led in production
It can accelerate construction progress；
2, by the way that connector is arranged to connecting rod and plugboard, it is only necessary to which connecting rod is inserted into the first connection ring and second
In connection ring, and plugboard is inserted into two adjacent templates to the grafting that two neighboring plugboard can be completed, construction is more
It is easy, it is convenient for disassembly and assembly.
