Description
Technical field
The present invention relates to the technical field of construction of ditch cable trench, and in particular to a kind of ditch cable trench constructing device and its
Construction method.
Background technique
With the speed-raising again and enlarging of China railways, all standing of high-speed rail is gradually formed, this is not only to railway main line
It builds and proposes high request, while requirements at the higher level also are proposed to the efficiency of building of the accessory building facility of Along Railway.
Positioned at the ditch of rail on both sides and cable trough as the embedded slot drained in railway tunnel with cable in railway tunnel
Very important effect is played to the normal operation of railway, due to the scrambling of its construction, causes the slow of real construction efficiency
Slowly, the form of construction work of existing railway tunnel ditch cable trench is roughly divided into two classes according to the difference of construction technology:
The advantages of first kind is to be spliced using pre-processed trench cell, this mode is construction technology content
It is low, high-efficient, short construction period, but since the tunnel in practical construction is often all located in mountain area, the groove list of installation forming
Member needs to cause transportation cost high, fortune in the good concrete groove shipped of factory process to construction tunnel project site
The excessive problem of throughput rate, simultaneously as the design of the ditch of railway tunnel and cable trough is usually to be integrally designed, it is desirable that there is height
Intensity, high life, the groove of splicing will appear crackle at splicing gap, cause to seal it is bad, the problems such as leak, so now
Substantially this kind of construction method is seldom used.
Second class is cast-in-place method, i.e., is fixed using template, concreting is formed in template, this to apply
Work technique has good airproof performance, and intensity is high, service life long advantage, for existing railway tunnel ditch cable trench generally use apply
Work method.
But because works is relatively narrow when due to current railway, the construction of highway ditch cable trench, formwork reinforcement and its difficulty are existing
Have generally using the seamless steel pipe of fixed length come support shuttering in technology, according to strong mould situation, using manually by steel pipe cutting or use
The modes such as flitch feet are controlled, are reinforced.It is used again after template position confirmation and manually carries out hammering into shape the methods of striking steel, tapping
Pipe is closely connect with template and ground, final fixed-type, then by chute placing concrete, completes to construct, but this
There is also following defects for kind method:
(1) fixed form of steel pipe and feet, poor accuracy are used, and operating process is difficult to control, template is easy to appear
The phenomenon that running mould, faulting of slab ends, reduces the accuracy of template；
(2) during placing concrete, chute concrete at shift position is easy to be scattered, it cannot be guaranteed that construction site
Cleannes.
In view of this, being badly in need of improving existing ditch cable trench formwork reinforcement and casting method, race is avoided the occurrence of
The phenomenon that mould, faulting of slab ends, increases the accuracy of template, while during placing concrete, keeps construction site cleaning.
Summary of the invention

When construction, after plate device, which installs, has casting concrete condition, the chute made is placed on electricity
Above cable slot template, tail end is carried chute pair after concrete tank is in place by the bottom alignment in chute channel 30 position to be poured
Concreting is carried out among the chute that standard places, baffle 80 is placed on the top of chute, and control two sides groove body pours speed
Degree and quantity.
Worker is ready at all times to carry out the adjustment of concrete using baffle 80 in casting process, i.e., when sending out abutment wall existing
The concrete of certain altitude has been poured, has timely used baffle 80 to coagulation when the height that another road abutment wall pours is relatively low
Soil pours too fast closing over there, and concrete is allowed to flow to the low side of absolute altitude, and so on finished until concrete uniformly pours.
The present invention can effectively control ditch cable trench two sides concreting speed by baffle, big using this chute
Reduce greatly because of concrete delivery truck deviation in place, works is partially narrow, traditional chute is mobile falls concrete problem, operation letter
It is single.
Work progress of the invention specifically includes the following steps:
Step 1 clears up substrate, and after survey engineer setting-out, installation template, the lower mouth of template sets Steel-bar Pile reinforcing, and
Adjust formwork elevation measuring；
The first bracing means is arranged in the top of step 2, template, and the pin of the first bracing means is inserted into the pre- of template
It boxes out, rotates first sleeve, template size is made to meet the requirements；
The second bracing means is arranged between two side templates for step 3, rotates second sleeve, makes ditch cable trench two sides wall
Spacing meet the requirements；
Step 4, chute place the position for needing to pour, utilize the baffle controls progressive die concrete being equipped in casting process
Quantity and speed, pour completion one section after, be moved to next section；
Construction is completed in step 5, form removal and health.
The present invention adjusts ditch cable trench by the second bracing means by the size of the first bracing means adjusting template
The distance between two sides wall effectively controls the problem of template runs mould, faulting of slab ends, while using special chute, is effectively promoted
Speed of perfusion, solves the problems, such as to fall concrete very well.
The invention is not limited to above-mentioned preferred forms, and anyone should learn that is made under the inspiration of the present invention
Structure change, the technical schemes that are same or similar to the present invention are fallen within the scope of protection of the present invention.
