Abstract
The utility model provides an extruded sheet side template structure, this structure is at the inboard one deck plywood that bonds of steel sheet pile, again with extruded sheet laminating nail tightly be fixed in on the plywood, lay between the inboard of extruded sheet and the raft foundation and paste waterproofing membrane. The problem that the brick bed-jig of the raft foundation and the waterproof roll of the foundation are often damaged by shaking in the process of removing the enclosure structure is solved. Belongs to the technical field of building construction.
Description
Technical Field
The utility model relates to an extruded sheet side template structure belongs to construction technical field.
Background
Along with the continuous development in the deep foundation pit field and the shortage of urban sites, the distance between the pile foundation and the raft foundation designed by a plurality of foundation pits is compact, under the condition that super-thick silt exists in the geology, the construction of the super-deep raft foundation needs an enclosure structure for construction, steel sheet pile enclosure is commonly used, a brick bed film of the raft foundation and a waterproof coiled material of the foundation can be damaged frequently due to shaking in the process of removing the steel sheet pile, the structure quality is unfavorable, and therefore how to effectively solve the problems is one of the technologies needing to be researched at present.
Disclosure of Invention
The utility model provides an extruded sheet side template structure to the in-process of solving envelope and pulling out often can destroy raft foundation's brick fetal membrane and basic waterproofing membrane's problem because of the shake.
In order to solve the problems, the side formwork structure of the extruded sheet is to be adopted, the structure is to bond a layer of plywood on the inner side of a steel sheet pile, then the extruded sheet is tightly attached and nailed on the plywood, and waterproof coiled materials are paved between the inner side of the extruded sheet and a raft foundation.
In the side formwork structure, the waterproof coiled material is connected to a raft foundation in a pre-laying and reverse-adhering mode;
in the side formwork structure, the waterproof coiled material is a high-density polyethylene self-adhesive film waterproof coiled material;
in the side formwork structure, the thickness of the plywood is 5 mm.
Compared with the prior art, the utility model discloses the vibrations that utilize extruded sheet's fragility and plasticity to remove the avoidance steel sheet pile to pull out cause destruction to raft foundation's lateral wall template, when raft foundation and steel sheet pile envelope are very close, adopt the brick fetal membrane to destroy because of causing the extrusion to it when the steel sheet pile is pulled out easily, and the waterproofing membrane on the brick fetal membrane also can appear damaging the circumstances such as because the destruction of brick fetal membrane, utilize extruded sheet plasticity when the steel sheet pile is pulled out, even take place the extrusion also can not cause great influence and destruction to it because extruded sheet's plasticity, and waterproofing technique adopts the technique of the anti-sticking of pre-paving, under extruded sheet is by the extruded circumstances, can also drive waterproofing membrane and structure more laminating, improve the waterproof performance of structure.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
To further clarify the objects, technical solutions and advantages of the present invention, the present invention will be described in detail with reference to the accompanying drawings, and it should be understood that the embodiments described herein are only used for the purpose of explanation and are not intended to limit the present invention.
In the geology of the super-thick sludge layer, a circle of steel sheet piles 1 are required to be constructed on the periphery of a large-size raft foundation 4 to serve as a surrounding structure, and the distance between the steel sheet piles 1 and the raft foundation 4 is 500 mm. And traditional brick fetal membrane construction can be because raft foundation 4 construction is accomplished the back under the condition of pulling out steel sheet pile 1, the condition that brick fetal membrane structure destroyed appears, and damage also can appear because of the destruction of brick fetal membrane in addition to waterproofing membrane 5 on the brick fetal membrane, and this is irreversible influence to raft foundation 4's waterproof quality and structural quality.
Examples
Referring to fig. 1, the extruded sheet 3 of the embodiment mainly comprises the steps of bonding a 5mm plywood 2 on a steel sheet pile 1 as a support for rooting of the extruded sheet 3, and nailing the extruded sheet 3 on the plywood 2 to ensure that the extruded sheet 3 does not collapse due to vertical paving and pasting to influence the construction efficiency and the safety of constructors; the raft foundation 4 is waterproof by adopting a pre-paving and anti-sticking waterproof technology, and a waterproof coiled material 5 of a high-density polyethylene self-adhesive film is pre-selected and paved on the extruded sheet 3, so that a complete and continuous adhesive layer with good waterproof performance is formed on the surface of the structural concrete, and the reliability of the waterproof layer on the structural protection is improved; because extruded sheet 3's fragility and plasticity, when steel sheet pile 1 is pulled out, plywood 2 with steel sheet pile 1 bonding can be taken out when steel sheet pile 1 is pulled out, and extruded sheet 3 also can be taken out along with pulling out of plywood 2 with the iron nail of plywood 2, and steel sheet pile 1 can cause the extrusion nevertheless can not cause the influence nature to its wholeness to destroy 3 extruded sheet at the extrusion of pulling out, and the laminating of waterproofing membrane 5 and structure can further be strengthened to extruded sheet 3's extrusion, improve the water-proof effects on its raft foundation.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
