The embodiment of the application also discloses a construction process for excavating the foundation. A construction process for excavating the ground includes the following steps:
s1: forming a hole;
the method comprises the steps of performing pore-forming operation on one side of the underground diaphragm wall by using a rotary drilling rig to form an operation hole, then performing foundation pile construction at the bottom of the operation hole, firstly putting a reinforcement cage with the height of 1 meter into the bottom of the operation hole during construction, pouring concrete with the thickness of 1M into the bottom of the operation hole after the reinforcement cage is in place, and forming a foundation pile with the reinforcement cage after the concrete is solidified.
S2: protecting the hole wall;
after the hole is formed, a plurality of pile casings 91 are spliced and then gradually placed into an operation hole by using a crane, when the pile casings 91 are placed, the pile casing 91 positioned at the bottommost layer is fixed by using the crane, then the rest pile casings 91 are sequentially spliced with the pile casing 91 positioned at the bottommost layer, when the pile casings 91 are spliced, two half casings 911 are spliced to form the pile casings 91 through the splicing groove 9111 and the insertion block 9112, and then the clamping ring 9113 of any pile casing 91 is inserted into the clamping groove 9114 of the other pile casing 91, so that the two adjacent pile casings 91 can be fixed; after each layer of pile casing 91 is installed, the crane drives the bottom layer pile casing 91 to move downwards for a certain distance until the bottom layer pile casing 91 is contacted with the foundation pile, and then the crane is separated from the bottom layer pile casing 91; at this time, since the soil in the foundation is not yet excavated, after the casing 91 is placed in the working hole, the casing 91 can play a role in reinforcing and protecting the hole wall of the working hole, thereby reducing the collapse of the hole wall of the working hole.
S3: building equipment for foundation excavation construction;
after pile casing 91 is spliced, the equipment for foundation excavation construction is installed, during installation, a crane for a scaffold 1 is placed into the inner side of the pile casing 91, then, a worker walks downwards along a ladder stand 9115 on the inner wall of the pile casing 91, when the worker walks to a foundation pile, the scaffold 1 and the foundation pile are fixed through expansion bolts, in order to further fix the scaffold 1, the scaffold 1 and a ground connecting wall are fixed through the expansion bolts, then, other parts in the equipment for foundation excavation construction are installed on the scaffold 1, during installation, a material box 5 and a clamping assembly 8 are located above the pile casing 91 on the highest layer, and therefore the excavated soil is poured into the material box 5 by the worker.
S4: digging soil;
when the soil is excavated, the soil outside the pile casings 91 is excavated by an excavator and poured into the material box 5, after the soil outside the pile casings 91 is excavated to a certain height, if the pile casing 91 on the uppermost layer is completely exposed above the soil, the pile casing 91 on the layer is removed, and then the soil is continuously excavated downwards.
S5: conveying soil;
when the soil in the material box 5 is filled to a certain amount, the material box 5 is clamped by the clamping component 8, the material box 5 is driven to the upper part of the ground by the first driving component, after the material box 5 is conveyed to the upper part of the ground, the telescopic arm 76 drives the material box 5 to move towards one side far away from the scaffold 1, the soil pulling vehicle is started to the outer side of the operation hole, the sixth motor 62 drives the rotating bottom plate 67 to rotate downwards, so that the discharge hole 51 is opened, the soil in the material box 5 can fall onto the soil pulling vehicle, finally, the sixth motor 62 drives the rotating bottom plate 67 to rotate to the original position, the discharge hole 51 is sealed, the first lifting component 7 drives the clamping component 8 and the material box 5 to move, and the material box 5 is placed in the original position; in the process of conveying soil to the road surface, a first lifting assembly 7 and a clamping assembly 8 work corresponding to two feed boxes 5 on a toothed ring 44, and when soil is poured towards one feed box 5, the first lifting assembly 7 conveys the other feed box 5 to the position above the road surface for soil pouring.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
