Abstract
The invention discloses a construction method for an underground waterproof coil material of a large deep foundation pit. The large deep foundation pit comprises a supporting structure, wherein a treatment layer is arranged on the outer side of the supporting structure; the waterproof coil material is arranged on the outer side of the treatment layer; the waterproof coil material is fixed through a steel nail; and a gasket is mounted on the steel nail in a sleeving manner. The construction method achieves the beneficial effects that procedures of binding reinforcing bars, arranging a template, pouring structural concrete, and the like, can be directly carried out without the requirement of laying a protective layer, the operation is easy and convenient, the construction procedures are less, the construction progress is fast, the construction quality is improved, and the construction cost is reduced.
Description
Technical field
The present invention relates to a kind of large deep foundation pit underground waterproof coiled material construction method.
Background technology
In building trade, especially large-and-medium size cities high-rise civil building and commercial building, the most all use support deep pit Large Underground Parking Space form, increased available space as far as possible and reduce cost.But at present, China's overwhelming majority underground engineering all uses traditional material, traditional construction construction technology waterproof layer, and the defect of this way is when waterproof layer is destroyed, and subsoil water can form crossfire between waterproof layer and structure.The ratio that Chinese large-sized deep basal pit has supporting underground waterproof engineering pre-installed and inverted adhered new waterproofing techniques to use at present is the lowest, and it has bigger development and application prospect in China, promotes the development of this technology will to produce huge economic benefit and social benefit energetically.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, it is provided that a kind of large deep foundation pit underground waterproof coiled material construction method, it is not necessary to lay any protective layer and can directly carry out assembling reinforcement; install template; the operations such as pouring structure concrete, it is achieved that less operation, reduce the duration.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
One large deep foundation pit underground waterproof coiled material construction method of the present invention, including supporting construction, the outside of described supporting construction is provided with process layer, and the outside of described process layer is provided with waterproof roll, described waterproof roll is fixed by steel nail, and described steel nail is set with pad；
Its construction method is: carries out campshed, diaphram wall according to design, inverse makees the construction of arch wall enclosed structure, carries out base cleaning, put waterproof roll location line and fixing point bit line.
Further, paving waterproof roll, when coiled material is used in plane, high density polyethylene (HDPE) is carried out empty paving facing to bed course；When coiled material is used in facade, using mechanical means that waterproof roll is fixed on building enclosure wall supporting surface, adhesive layer is towards structure sheaf.
Further, after fixing end, use Special seal material to carry out adhering and sealing in minor face lap-joint or fixing point, be not required to after having checked and accepted lay protective layer, can directly carry out assembling reinforcement, install template, pouring structure concrete subsequent handling.
The present invention is reached to provide the benefit that: can directly carry out assembling reinforcement without laying any protective layer, install the operations such as template, pouring structure concrete, the most easy and simple to handle, working procedure is few, and construction speed is fast, and improves construction quality, reduces construction cost.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, is used for together with embodiments of the present invention explaining the present invention, is not intended that limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
In figure: 1, steel nail；2, pad；3, layer is processed；4, waterproof roll；5, supporting construction.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
Embodiment 1
As it is shown in figure 1, a kind of large deep foundation pit underground waterproof coiled material construction method, including supporting construction 5, the outside of described supporting construction 5 is provided with process layer 3, the outside of described process layer 3 is provided with waterproof roll 4, and described waterproof roll 4 is fixed by steel nail 1, described steel nail 1 is set with pad 2；
Its construction method is: carries out campshed, diaphram wall according to design, inverse makees the construction of arch wall enclosed structure, carries out base cleaning, put waterproof roll location line and fixing point bit line.
Paving waterproof roll, when coiled material is used in plane, carries out empty paving by high density polyethylene (HDPE) facing to bed course；When coiled material is used in facade, using mechanical means that waterproof roll is fixed on building enclosure wall supporting surface, adhesive layer is towards structure sheaf.
After fixing end, use Special seal material to carry out adhering and sealing in minor face lap-joint or fixing point, be not required to after having checked and accepted lay protective layer, can directly carry out assembling reinforcement, install template, pouring structure concrete subsequent handling.
Can directly carry out assembling reinforcement without laying any protective layer, install the operations such as template, pouring structure concrete, the most easy and simple to handle, working procedure is few, and construction speed is fast, and improves construction quality, reduces construction cost.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
