Description
Technical field
The utility model relates to building backfill application, especially relates to a kind of pit backfill structure.
Background technology
Along with the development in city, the basement degree of depth of city new building constantly increases, and which increases deep pit digging difficulty, also improves the quality requirement of pit backfill engineering.Vibration watertight method is a kind of pit backfill construction technology, its technological principle is paved according to certain loose laying depth by sandy soil filler, adds water saturation, with plug-in type vibrating rod vibration compacting, after vibrating, treat that filling surface reaches the degree of compaction that certain aridity detects every layer again.This backfilling process can not only solve the pit backfill construction difficult problem that the degree of depth is comparatively large, working space is narrow, also can greatly improve pit backfill workmanship, reduces construction safety hidden danger.
Chinese patent CN203546759U discloses the plugging structure of post-cast strip for underground building, aim to provide that a kind of structure is simple, the scope of application extensively, easy construction, minimizing potential safety hazard, reduce the plugging structure of the post-cast strip for underground building of later stage expense.Comprise concrete exterior wall and ater-casting, also comprise precast plate, connector, ater-casting reserved steel bar and leveling layer; Precast plate is thrown into the outside of ater-casting; Connector connects precast plate and ater-casting reserved steel bar; After precast plate is installed, leveling layer is put on outside precast plate.But this kind of plugging structure cannot realize backfill function.
Utility model content
The purpose of this utility model is exactly provide a kind of overall structure simple to overcome defect that above-mentioned prior art exists, practical, easily manufactured, is easy to the pit backfill structure promoted the use of.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pit backfill structure, comprise water pump, weeper drain, backfilling material, dewatering well, storage tank, the first water pipe and the second water pipe, described water pump is arranged on the least significant end of dewatering well, through the first water pipe be arranged on ground storage tank and be connected, described weeper drain is opened in the bottom of dewatering well, described backfilling material is deposited in outside dewatering well, is connected with storage tank through the second water pipe.
The low side of described dewatering well is positioned at the pedestal place of outer wall of basement.
Described dewatering well is made up of Plant holdfast and protecting wire net layer, and described protecting wire net layer forms the side wall construction of dewatering well; Described protecting wire net layer is supported by Plant holdfast.
Described weeper drain is provided with two-layer building net.
The second described water pipe contacts with the top of backfilling material.
Compared with prior art, structure of the present utility model is suitable for vibration watertight method construction technology, and not only solve the pit backfill construction difficult problem that the degree of depth is comparatively large, working space is narrow, also large raising pit backfill workmanship, reduces construction safety hidden danger; Overall structure is simple, practical, easily manufactured, is easy to promote the use of.
