In order to effectively expand the width of the road surface, old houses on two sides of the road surface are dismantled.
However, a phenomenon exists in the removal process, part of reserved houses have certain historical value, and some buildings are even listed as material cultural heritages and have certain protection significance. It is apparent that these old buildings cannot be directly dismantled for road widening, and a new solution is needed to solve this problem.
Disclosure of Invention
The invention aims to provide a house moving method in building construction, which can move for a short distance without dismantling a house, thereby facilitating planning and construction of urban infrastructure projects.
The technical purpose of the invention is realized by the following technical scheme:
a house moving method in building construction comprises the following steps:
a first step of excavating an annular working pit around a foundation of a house;
secondly, in the operation pit, utilizing a reinforcing plate to perform surrounding type fixing on the side surface of the foundation;
thirdly, excavating unit blocks on the foundation base part in the operation pit in a side-excavating and supporting mode, and supporting the foundation by using unit supporting modules after each unit is excavated; and detachably connecting and fixing the adjacent unit supporting modules;
fourthly, a slideway which is connected with the lower end face of the foundation is arranged near the operation pit, and the part of the operation pit adjacent to the slideway is backfilled;
and fifthly, pushing the house to slide to a preset position along the slide by using the cart force application reinforcing plate.
By adopting the technical scheme, the operation pit is used for exposing the side surface of the foundation, so that the foundation can be conveniently excavated and supported by constructors from the side surface.
The house can be moved by excavating the entire foundation so that the house is supported by the plurality of unit support modules while the foundation below the house is separated from the ground.
The side surface of the house is surrounded by the reinforcing plate and fixed to protect the house; when the house is pulled, the reinforcing plates surround the house, the moving force is transmitted to a plurality of side faces of the house, the pressure intensity applied to the house in the moving process is reduced, and the loss of the house in the moving process is reduced.
The bearing surface of the slideway is smoothly connected with the upper surface of the unit supporting module, so that the house smoothly slides to the slideway from the unit supporting module and further moves to a preset position.
In the design, the house is effectively separated from the ground by utilizing the mode of gradually opening and gradually supporting the unit blocks below the foundation one by one, and the house is protected in place in the process, so that the loss of the house in the moving process is very little.
Preferably, in the third step, after each unit block is excavated, the bottom of the foundation under the unit is reinforced by the aluminum membrane plate, and the hardened reinforced concrete block is supported by the unit supporting modules.
By adopting the technical scheme, the reinforced concrete of the unit is reinforced below the foundation, so that the loss of the foundation in the moving process is reduced, and the integral structural strength below the house is increased; after the house is moved to a new preset position, the reinforced concrete structure below the house can increase the overall firmness of the house.
Preferably, the steel bars of the reinforced concrete blocks under the adjacent units are bound, and concrete is poured for fixation.
Through adopting above-mentioned technical scheme, the reinforced concrete piece that will go up each unit piece is cemented each other and is fixed and can form a comparatively smooth slip face, is favorable to the stability when house later stage slides.
Preferably, in the third step, the adjacent unit support modules are detachably fixed.
By adopting the technical scheme, the unit supporting modules are fixed to each other to form a whole, which is obviously beneficial to improving the stability of the house support when the lower parts of the foundations are excavated one by one; the method has the advantages that after the outer wall is excavated below the foundation, when the house moves on the integral unit supporting modules, the friction resistance generated on the lower unit supporting modules when the house moves is not uniform, and as all the unit supporting modules are fixed into a whole, the unit supporting modules are not easy to collapse, so that a stable and relatively flat sliding surface can be provided by using the unit supporting modules, and the stability of house sliding is improved.
Preferably, in the third step, the reinforcing plate detachably fixes the adjacent unit support modules.
By adopting the technical scheme, the fixing of the reinforcing plate and the unit supporting module is beneficial to improving the firmness of connection between the unit supporting module and a house, so that the excavation and supporting procedures below the foundation are safer. Therefore, when the back-end house is moved by using the detachable connection method, the reinforcing plate needs to be separated from the unit supporting module.
Preferably, in the third step, the supporting of the unit supporting modules of at least three corners at the bottom of the foundation is completed firstly, then the foundation base is subjected to gradual hollow-out treatment, and the foundation base extends outwards from the center of the foundation to complete the overall supporting below the foundation.
By adopting the technical scheme, the characteristic that the triangle has stability is utilized, the unit supporting modules are supported at the three pivot positions, then the foundation base part is hollowed out, and the supporting of the corner unit supporting modules to the center of the foundation is completed in the hollowing process.
Preferably, in the second step, the sliding side guard plates are installed on the ground, the side guard plates are symmetrically installed on two wings of the house, and the side guard plates and the reinforcing plates are detachably connected and fixed.
By adopting the technical scheme, the side guard plates are firstly used for supporting the house, and the support on the two sides is utilized to reduce the shaking of the house in the operation of the unit supporting module;
secondly, when the house removes, two side shields are equivalent to two flanks, and the equilibrium degree when the house removes can be increased for the house is more steady at the removal in-process, has reduced the house and has removed the in-process because excessively rock the damage that causes.
Preferably, the reinforcing plate and the side guard plate are reinforced by a guy cable.
Through adopting above-mentioned technical scheme, the cable effectively increases the fastness between gusset plate and the side guard plate.
Preferably, in the fifth step, the reinforcing panels and the side guards are removed after the house is moved to the predetermined position.
By adopting the technical scheme, the house is moved to the preset position, only the house and the ground are required to be reinforced, and the original reinforcing plates and the side guard plates can be recycled, so that the resource waste is reduced.
Preferably, in the fifth step, the house is moved to the predetermined position by a distance in the range of 5-50 m.
By adopting the technical scheme, the house moving distance is too long, the loss to the house is larger, and the house moving range is controlled to be optimal within 5-50 meters through simulation test because the house moving distance is designed in the design scheme; the reason is that, at distances less than 5 meters, the road can be redirected relatively easily, and the cost is less for moving the house; when the house moves more than 50m, the shaking and swaying time of the house moving is large, so the moving distance is preferably controlled within 50 m.
In conclusion, the invention has the following beneficial effects: the foundation of the house is separated from the ground by using the unit supporting module, and the house is pushed to a preset position by using a cart in a mode of surrounding and protecting the house by a reinforcing plate.
Further, the concrete of ground below adopts the aluminium template shaping to fix in this design, will carry out recycle to the aluminium template after the construction, to the secondary recycle of building materials, has embodied the green building construction technology that the country advocated.
In addition, the middle reinforcing plate, the side guard plates and the unit supporting module are detachably connected and fixed, and can be used for next house moving construction, so that the waste of construction building materials can be greatly reduced, and the green building construction technology is embodied.
The noun in the scheme explains that: the concrete block is equivalent to a reinforced concrete block.

Second, the adjacent unit support modules 32 are detachably fixed by bolts and nuts when the supports are installed.
Third, the reinforcing plate 41 is detachably fixed to the adjacent unit support module 32 by bolts and nuts.
The three points are required to be synchronously carried out when the unit block is excavated and supported.
After the lower portion of the foundation 21 is completely supported by the unit supporting module 32, the fourth step is performed.
As shown in fig. 4 and 5:
fourthly, digging a slideway near the operation pit 1, wherein the slideway is communicated with the operation pit 1; the bearing surface of the slideway is as high as the supporting surface formed by the unit supporting modules 32, at the moment, one side of the operation pit 1 adjacent to the slideway is backfilled, and the backfilling height is as high as the bearing surface of the slideway; the slide way is a straight line way, and the side protection plates 42 are right at the two sides of the slide way, so that the house body 2 can smoothly move on the slide way. The bottom of the slideway should be paved with a foundation stone, one side of the house body 2 is downward in the moving process, a sand layer with the thickness of 10cm on one side should be paved above the foundation stone, and the friction resistance of the house body 2 in the moving process can be reduced by dense sand grains in the sand layer.
