In addition, because the spacing distance between the extension building envelope and the existing building envelope is larger, soil around the existing building envelope loosens to cause the existing building envelope to lack extrusion force, thereby influencing the structural stability of the existing building. In addition, when the existing building constructed by adjacent water and adjacent mountains is involved, when the enclosure structure is expanded outside the adjacent water surface or the adjacent mountains of the existing enclosure structure, on one hand, construction is inconvenient, and on the other hand, after construction, because the expanded enclosure structure is closer to the water or the adjacent mountains, potential safety hazards can be caused to the structural safety of the existing building body. Therefore, how to reduce the safety and the structural stability of the existing building and the adjacent buildings in the construction of the basement extension envelope structure becomes a technical problem which needs to be solved in the field.

Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
referring to fig. 2, an embodiment of the present invention provides a method for constructing a newly-built enclosure structure for expanding an existing basement, wherein a newly-built underground continuous wall 200 is constructed on the inner side of an existing fender pile 101 through an area of an existing engineering pile 102, and the newly-built underground continuous wall 200 is the newly-built enclosure structure.
Referring to fig. 5, in the method for constructing a newly-built enclosure structure for expanding an existing basement according to the embodiment of the present invention, the method for constructing a newly-built underground continuous wall 200 through an area of an existing engineering pile 102 includes:
step 501, please refer to fig. 1 and fig. 3, pay off and position the underground continuous wall to be built in the area of the existing engineering pile 102, and drive the steel casing 301 to rotate downwards to cut the soil drilling hole 201 to a predetermined depth in the pay-off and position area by using the full slewing drilling machine 300.
Step 502, please refer to fig. 1 and 4, when the steel casing 301 of the full slewing drilling machine 300 encounters the existing engineering pile 102 in the process of rotationally cutting the wall borehole 201, the existing engineering pile 102 is separated from the soil body 402, a wedge-shaped hammer 303 is placed between the steel casing 301 and the existing engineering pile 102, the wedge-shaped hammer 303 rotates along with the copper casing 301 to cut off or twist off the existing engineering pile 102 to form an existing engineering pile section, and the existing engineering pile section is pulled out section by section. Wherein the wedge hammer 303 may also be referred to as a drill steel, a clamping bar, and an inverted triangular hammer. Where steel casing 301 has a diameter greater than the diameter of existing engineered pile 102. The existing engineering pile section can be pulled out by a crane. After the hole 201 is cleared, firstly, the cement soil is backfilled to a certain depth, and then the steel sleeve 301 is pulled out while the cement soil is backfilled, wherein the bottom of the steel sleeve 301 is always kept below the cement soil. The cement soil is reserved on the steel sleeve 301 by a certain amount, so that the condition that the amount is insufficient when the steel sleeve is pulled out is avoided, and the cement soil is a mixture of cement and soil.
Step 503, please refer to fig. 1, a trenching machine is used to remove the line-laying positioning area and the soil body in the drill hole 201 to form a trench 202, guide wall templates are arranged at two sides of the trench 202 to pour concrete to form guide walls, and a reinforcement cage is hung in the trench 202 between the guide walls and concrete is poured to form the newly-built underground continuous wall 200. The trenching machine in step 503 is a dual-wheel trenching machine that has dual functions of trenching and clearing obstacles. In this step 503, before forming the groove 202, a gantry column may be disposed along the line-releasing positioning area to ensure the accuracy of the construction position of the guide wall.
In the embodiment of the invention, the method for constructing and newly building the underground continuous wall 200 through the area of the existing engineering piles 102 is to pass through the area of the existing engineering piles 102 and carry out pile pulling treatment on the existing engineering piles 102 with obstacles, thereby constructing and newly building the underground continuous wall 200. The method utilizes the effective area of the existing basement of the existing building to be constructed, and avoids the influence on the structural performance and the safety performance of the adjacent existing building caused by crossing the adjacent existing building. And the influence of the newly-built underground continuous wall 200 on the structural performance and the safety performance of the existing building to be built due to the proximity of the adjacent mountains, the adjacent water and other areas is avoided.
In the embodiment of the invention, the method for constructing and newly building the underground continuous wall 200 through the area of the existing engineering pile 102 adopts the full slewing drilling machine 300, and can utilize the steel sleeve 301 for retaining soil when drilling downwards through the steel sleeve 301, so that hole collapse is prevented, and the influence on the surrounding environment is reduced. Removing the obstacles and digging to form the groove 202 by means of a two-wheel slot milling machine reduces the risk of tilting or cracking the surrounding structure building, thereby reducing the impact on the surrounding environment.
Referring to fig. 1 and fig. 2, in the method for constructing a newly-built enclosure structure for expanding an existing basement according to the embodiment of the present invention, a newly-built underground continuous wall 200 of a corresponding surface is constructed on the inner side of at least one surface of an existing fender post 101 through an area of an existing engineering post 102, and a newly-built underground continuous wall 200 of a corresponding surface is constructed on the outer side of the remaining surface of the existing fender post 101 and in close contact with the existing fender post 101, so that all the newly-built underground continuous walls 200 are connected to form a newly-built fender post. The embodiment of the invention includes, but is not limited to, constructing the newly-built underground continuous wall 200 of the corresponding surface through the existing engineering pile 102 area at the inner side of the south surface of the existing fender pile 101, and constructing the newly-built underground continuous wall 200 of the corresponding surface by clinging the existing fender pile 101 at the east surface, the north surface and the west surface of the existing fender pile 101.

Referring to fig. 6, the method for constructing a newly-built enclosure structure for expanding an existing basement according to the embodiment of the present invention includes the following steps:
The method for constructing the newly-built underground continuous wall 200 of the corresponding surface by clinging to the existing fender post 101 means that a small gap exists between the newly-built underground continuous wall 200 and the existing fender post 101, and the size of the gap is determined by the fact that the soil body between the newly-built underground continuous wall 200 and the existing fender post 101 is loosened and extruded by the newly-built underground continuous wall 200, so that the existing fender post 101 is not loosened. The construction is closely attached, and the structural stability and the safety of the existing building can be ensured.
In the embodiment of the invention, when the newly-built underground continuous wall 200 is constructed outside the existing fender post 101 and clings to the existing fender post 101, because no obstacle of the existing engineering post 102 blocks the newly-built underground continuous wall, a back-hoe excavator can be adopted to directly form the groove 202, and the construction difficulty is reduced.
