Abstract
The invention relates to the technical field of construction engineering, in particular to an underground arch top plate mounting method. The method mainly comprises the steps that a pipe roof is driven into soil for forepoling, a groove is drilled, longitudinal beams are mounted, and a prefabricated arch top plate is mounted. By means of the underground arch top plate mounting method, the quality is reliable, cost is low, the effects of environment protection and energy conservation are achieved, construction is easy and safe, the construction period is short, and the waterproof effect is good.
Description
Technical field
The present invention relates to construction engineering technical field, specifically the mounting method of a kind of underground arch top board.
Background technology
The construction in current interval tunnel mainly contains shield method or shallow burial hidden digging.Wherein, shield method is applicable to middle Soft Soil Layer and the larger running tunnel of buried depth, adopts shield duct piece to carry out supporting, has that cost is higher, time is longer, shield structure well affects the defects such as road traffic.Shallow burial hidden digging adopts steel grating, sprayed mortar, form concrete composition support system, need at underground cast-in-place steel concrete, exist long in time limit, poor working environment, security risk are many, quality is difficult to ensure the defects such as card.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, providing that a kind of reliable in quality, with low cost, environmental protection and energy saving, construction are simple and safe, short construction period and the technical scheme of the mounting method of the underground arch top board of good water-proof effect.
Technical problem to be solved by this invention realizes by the following technical solutions: the mounting method of a kind of underground arch top board, comprises the following steps:
A: be drilled with groove to projected depth in the soil body;
B: two longerons are inserted in groove, makes two longerons be overlapped on the concrete precast pile of both sides, tunnel respectively;
C: inserted one by one in groove by prefabricated arch top board, makes the both sides of prefabricated arch top board be overlapped on longeron, and multiple prefabricated arch top board connects as one.
Technical scheme of the present invention also has: in the soil body, set pipe canopy before described step a carry out advance support.Adopt the technical program, can prevent from being drilled with soil body landslide in groove process.
Technical scheme of the present invention also has: after described step c completes, extract pipe canopy and inject the hole that cement grout backfill pipe canopy formed at soil layer.Adopt the technical program, can realize the recovery of pipe canopy, the secondary contributing to pipe canopy utilizes, and has saved steel.
Technical scheme of the present invention also has: described concrete precast pile is provided with bracket, and the both sides of described prefabricated arch top board are overlapped on bracket.
Technical scheme of the present invention also has: be provided with water proof rubber pad between adjacent two prefabricated arch top boards in described step c, and described water proof rubber pad arranges continuously along the end face of prefabricated arch top board and bonds with the end face of adjacent two prefabricated arch top boards fixing respectively.Adopt the technical program, ensure the waterproof effect of underground arch top board.
Technical scheme of the present invention also has: the installation using hanging device false longeron and prefabricated arch top board in described step b and step c.
Technical scheme of the present invention also has: the material of described prefabricated arch top board is fibrous concrete.Adopt the technical program, the toughness of prefabricated arch top board is high, reduces the possibility of prefabricated arch roof break.
Technical scheme of the present invention also has: the span of described prefabricated arch top board is 4.5-7 rice, and the length of prefabricated arch top board is 2-6 rice.
Relative to prior art, beneficial effect of the present invention is:
(1) due to prefabricated arch top board of the present invention be tie up muscle, formwork in the factory, build, maintenance forms, therefore its quality is better than cast in situs, ensure that workmanship.
(2) because prefabricated arch top board of the present invention is in factory's centralized production, the dispersion avoiding the resource such as material, electric power uses, and waste reduces, with low cost, also reduces the impact of cast in situs construction on surrounding environment, shortens construction period.
(3) mounting method of underground of the present invention arch top board is assembled by multiple volume, the rational prefabricated arch top board of weight, and the process of the therefore transport of prefabricated arch top board, lifting, installation is simple, safety.
