Description
Technical field
The present invention relates to subway work technical field, in particular to a kind of subway station hole for hoist method for blocking.
Background technique
With the continuous development of raising and the transport development of china's overall national strength, China's underground traffic infrastructure is rapidly sent out
Exhibition, each big city starts to build subway engineering successively；Subway station generally can all select AT STATION during design and construction
Preformed hole is set on the top plate and middle plate above the area Gui Hang to meet a variety of materials equipment hoisting needs such as the section of track, shield machine；It stands
Interior construction then needs to block these ducts close to complete working hour；Open cut of subway station reserving hole closure at present is generally adopted
With support cast-in-place construction technique, intensive labor is needed, at high cost, low efficiency is unfavorable for the duration.
Summary of the invention
It is an object of the invention to overcome the existing open cut of subway station reserving hole in the presence of the prior art to block one
As use support cast-in-place construction technique, need intensive labor, at high cost, low efficiency is unfavorable for the above-mentioned deficiency of duration, provides
A kind of subway station hole for hoist method for blocking.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes:
A kind of subway station hole for hoist method for blocking, comprising the following steps:
A, when making the hole for hoist of subway station, support end is set in the hole for hoist installation site surrounding；
B, several prefabricated cover boards, all cover boards successively hole for hoist described in spliced shape adaptation are each described
There is gap between cover board and the hole for hoist side wall contacted, there is gap between the two neighboring cover board；
C, all cover boards of handling are arranged at the correspondence hole for hoist, and all cover boards are corresponded to by the hole for hoist
The support end support；
D, all gaps are formed using concreting, are completed the hole for hoist and are blocked.
Using a kind of subway station hole for hoist method for blocking of the present invention, hole for hoist is blocked using the prefabricated cover board of handling
Mode do not need to set up bracket, installation template, assembling reinforcement and largely pour mixed compared with traditional support cast-in-place construction
The work of soil is coagulated, difficulty of construction reduces, while noise is small, pollution is small, and construction efficiency is high, short time limit used, while utilizing coagulation
Soil crams gap, so that cover board has certain waterproofness after blocking hole for hoist, meets subway station waterproof requirement, the closure side
Method step is simple, easy to operate, works well.
Preferably, each cover board connects the side of the support end and is arranged in mismatch, and the top of the side compared with
Lower part is prominent, so that each cover board is overlapped on the support end.
Preferably, the lower shape of each cover board is adapted to the notch that the support end surrounds.
Preferably, in the step D, all gaps are poured using C40 slightly expanded concrete.
Preferably, the size in each gap is 5cm-10cm.
Preferably, concrete is poured using hanging modulus method in the gap between the two neighboring cover board, i.e., described
Sunpender is set in gap, and the sunpender connects bed die, and the sunpender tenses, and the bed die fits in two adjacent lids
Plate, then casting concrete, maintenance remove the bed die after forming in the gap.
Preferably, water-swellable water-stop glue is equipped in each gap, the water-swellable water-stop glue is connected to described
Cover sidewall.
Since subway station needs strict waterproof performance, in this way, part water is leaked into the gap
After concrete, percolating water is after encountering water-swellable water-stop glue, since water-swellable water-stop glue is water expansion one-pack-type sealant,
One it is hardened reform into own vol expansion after the good rubber elastomer of restoration, immersion, filling gap play it is certain only
Water effect.
Preferably, pre-buried angle steel at two angles being oppositely arranged on the two neighboring cover board, when executing the step D,
After pouring all gaps, the welding steel on two adjacent angle steel.
Since subway station needs strict waterproof performance to can be improved two neighboring prefabricated lid in this way
Globality between plate, the waterproof performance of enhancing structure.
Preferably, after executing the step D, cast-in-situ steel reinforced concrete layer is set on all cover boards.
In this way, the integral waterproofing effect after hole for hoist blocks is further increased, simultaneously because cover board is overlap joint
On support end, hole for hoist needs backfill after blocking, and cast-in-situ steel reinforced concrete layer is arranged on the cover board and is capable of enhancing structure
Stability.
Preferably, the cast-in-situ steel reinforced concrete layer with a thickness of 10cm-20cm.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, with a kind of subway station hole for hoist method for blocking of the present invention, lifting is blocked using the prefabricated cover board of handling
The mode in hole is not needed to set up bracket, installation template, assembling reinforcement and largely be poured compared with traditional support cast-in-place construction
The work of concrete, difficulty of construction reduce, while noise is small, pollution is small, and construction efficiency is high, short time limit used, while utilizing mixed
Solidifying soil crams gap, so that cover board has certain waterproofness after blocking hole for hoist, meets subway station waterproof requirement, the closure
Method and step is simple, easy to operate, works well；
2, it is equipped with that meet water swollen with a kind of subway station hole for hoist method for blocking of the present invention, in each gap
Swollen water-stop glue, the water-swellable water-stop glue are connected to the cover sidewall, since subway station needs strict waterproof performance,
In this way, part water leaks into the gap after concrete, percolating water after encountering water-swellable water-stop glue, by
It is water expansion one-pack-type sealant in water-swellable water-stop glue, one hardened reforms into the good rubber elastomer of restoration, leaching
Own vol expansion, filling gap play certain water-stagnating effect after water；
3, opposite on the two neighboring cover board to set with a kind of subway station hole for hoist method for blocking of the present invention
Pre-buried angle steel at two angles set, when executing the step D, after pouring all gaps, in two adjacent angle steel
Upper welding steel, since subway station needs strict waterproof performance to can be improved two neighboring prefabricated in this way
Globality between cover board, the waterproof performance of enhancing structure；
4, with a kind of subway station hole for hoist method for blocking of the present invention, after executing the step D, in all institutes
Setting cast-in-situ steel reinforced concrete layer on cover board is stated, in this way, further increases the integral waterproofing effect after hole for hoist blocks
Fruit, simultaneously because cover board is overlapped on support end, hole for hoist needs backfill after blocking, and it is mixed that cast in place reinforced bar is arranged on the cover board
Solidifying soil layer is capable of the stability of enhancing structure.
