1A is a cross-sectional view showing a raker pile and a raker installation process in explaining a bottom-up sequential removal and sequential landfill method for removing an underground retaining wall according to prior art literature (Korean Patent Publication No. 2006-0103309), and FIG. 1B is In explaining the bottom-up sequential removal and sequential landfill method for removing the underground retaining wall according to the prior art literature, it is a perspective view showing the raker pile and the raker installation process, and FIG. 1c is a bottom-up sequential removal for removing the underground retaining wall according to the prior art literature. And in explaining the sequential reclamation method, the soil backfill is in progress and the lower raker, which no longer needs to support the retaining wall, is removed, while for the part where the retaining wall has been removed, the raker file used to support the retaining wall is pulled out. It is a cross section illustrating the concept.

The bottom-up sequential removal and sequential reclamation method for removing the underground retaining wall according to the prior art literature is proposed to fit the demolition of the basement that is not deep, as shown in FIGS. 1A to 1C. It is designed to be fixed to the raker pile 30 so that the raker 32, which has a different inclination after driving the raker pile 30 in the inner ground, supports the underground retaining wall 10 at an angle.

Applying the raker 32 with a different inclination means that there must be an inside of the space that has already been demolished, and this point is that the state immediately before the installation of the raker pile 30 and the raker 32 is blocked by the underground retaining wall 10 Since the earth pressure can collapse at any time, it is inevitable to be exposed to a very dangerous situation if the depth of the underground is deep, and in the end, demolition in the case of a deep underground layer has a limit that cannot be realized.

In addition, the soil backfilling process is also inconvenient [construction period extension] because the soil is forced to backfill the soil at an angle [to prepare for the removal of the raker 32] due to the slope of the raker 32 as shown in FIG. 10) is repeatedly exposed to the risk that the soil may collapse at any time due to the earth pressure applied to it, and furthermore, the earth pressure due to the soil backfill applied to the raker pile 30 is considerable, causing the raker pile 30 to bend in one direction or Not only can a bending phenomenon appear, but in order to overcome this, the thickness or depth for the bearing capacity of the raker pile 30 has to be further considered.

In the end, the bottom-up sequential removal and sequential reclamation method for removing the underground retaining wall in the prior art literature is designed to be suitable for places where the underground is not deep, and in particular, it requires the premise that there must be an inside of the space that has already been demolished. Due to (32), there are many problems such as bending or bending of the raker pile 30, difficulty and danger of backfilling, and in particular, the underground retaining wall 10 is used for heavy heating and It is mercilessly demolished with a strong commitment, resulting in damage to neighboring residents due to severe vibration and severe noise, as well as causing danger to neighboring buildings.

Furthermore, in the low-noise and low-vibration civil building safe cutting and demolition method according to the present invention, the 30th step (S30) demolishes the civil construction pieces 52a in ascending order as shown in FIGS. ) to the ground, soil backfilling (T) and compaction while dismantling the struts 65 and wales 64, so that the safe demolition of the underground building 50 can be realized, and furthermore, the 30th step (S30) After that, as shown in FIG. 5K, a 40th step (S40) of drawing out the post pile 61 and the H-beam H is further included to enable a satisfactory handover to a civil engineering company.

At this time, in the twenty-first step (S21), the through hole 53a is drilled in the center of the slab 53 of each underground floor, as shown in FIG. 5A, and the post pile 61 is placed in the through hole 53a. It is supported on the underground foundation 51 while being fitted into a plurality of pieces; In the 22nd step (S22), as shown in FIGS. 5B to 5E, the strut 65 is wrapped around the basement wall 52 together with a plurality of post piles 61 inserted into the through hole 53a ( 64) consisting of vertical and horizontal butting beams (65a) connecting the center; An omnidirectional work space G1 is secured in the vertical and horizontal directions from the post pile 61 to the basement wall 52 for each basement floor.

That is, the post pile 61 supporting the support 65 for preventing the collapse of the underground building 50 by the earth pressure of the earth and sand wall B is drilled in the center of the slab 53 of each underground floor. By securing the omnidirectional work space G1 in the underground building 50 by fitting it into the through hole 53a, the rotary cutting multi-joint heavy equipment 70 or other heavy equipment 80 [other for loading and unloading of civil engineering pieces 52a] This is so that the working range of the heavy equipment 80 can be guaranteed with ease.

When such an omnidirectional work space (G1) is not secured, the range of motion of the rotary cutting multi-joint heavy equipment (70) as well as other heavy equipment (80) is extremely limited, considering that workability is significantly reduced. Securing will be relatively desirable.

It may further include an oblique support 67 connecting the corner beam 66 of the adjacent upper floor in an oblique direction while being fixed to.

Since the corner beam 66 is supported by the wale 64 surrounding the corner of the basement wall 50, considering that the downward holding force may be weakened, While being fixed to the wale 64, an oblique support 67 connecting the corner beam 66 of the adjacent upper floor in an oblique direction is further installed to ensure the omnidirectional bearing capacity of the underground building 50 so as to be more free from the risk of safety accidents do.

Furthermore, in the low-noise and low-vibration civil building safe cutting and demolition method according to the present invention, in the 22nd step (S22), as shown in FIG. The foundation work space (G2) in the vertical direction from the basement foundation 51 to the lower middle of each basement floor by the oblique support 67 that is installed in descending order and at the same time supports the corner beam 66 in an oblique direction to secure

In other words, by utilizing the foundation work space (G2) secured from the middle and lower floors of each underground floor to the underground foundation (51), the underground foundation (51) is demolished without hesitation to ensure both stability and speed. When the underground foundation 51 is removed, only the area capable of supporting the post pile 61 is left and the underground foundation 51 is removed. In the case where the piles 61 are connected, it is of course possible to demolish all of the underground foundations 51 leaving only the micro piles].

There are wales 64, corner beams 66, oblique supports 67, diagonal braces 65b, and vertical and horizontal beams in the underground building 50, so if they are cut with the circular saw blade 71, a large accident may occur. Therefore, the laser is irradiated toward the outer periphery of one half of the circular saw blade 71 and the outer periphery of the other half of the underground wall 52, where visibility is inevitably secured due to dust, etc., to make linear cutting while checking the laser visually. This is to enable safe demolition to be realized.

As described above, the low-noise and low-vibration method for safe cutting and demolition of civil buildings according to the present invention is a piece of civil architecture by linearly cutting the civil buildings 500 by rotating together with changing the left and right angles of the circular saw blade 71 of the rotary cutting multi-joint heavy equipment 70.
