The purpose of this utility model can realize by taking following technical scheme:
The buttress type supporting and protection structure of foundation ditch diaphragm wall, comprises diaphragm wall, and its design feature is: in the top of diaphragm wall is arranged, lead wall, lead wall and Guan Liang, Guan Liang on the top of diaphragm wall outward and lead wall in being clipped in, lead between wall outward; Arrange first to support at the near coal-mine place of foundation ditch, described first supports and is fixedly connected with Guan Liang, forms top supporting and protection structure; Bottom foundation ditch, arrange waist rail toward position more than last layer basement height, described waist rail and diaphragm wall wall are fixedly connected to form second braced structures, i.e. lumbar support structure; Short beam is set in the below of waist rail, supports to form bottom basement structure, counterfort is set above waist rail, form layer second from the bottom or the buttress type braced structures along number second layer basement structure; Diaphragm wall wall bottom foundation ditch is provided with gutter.
The purpose of this utility model can also realize by taking following technical scheme:
Further, the thickness of described diaphragm wall can be 800mm.
Further, the height of described diaphragm wall is three layers of height sum to five layers of basement, is preferably the height sum of three layers of basement.
The utility model has following outstanding beneficial effect:
1, the utility model supports by arranging first at the near coal-mine place of foundation ditch, and described first supports and is fixedly connected with Guan Liang, forms top supporting and protection structure; Bottom foundation ditch, arrange waist rail toward position more than last layer basement height, described waist rail and diaphragm wall wall are fixedly connected to form second braced structures; Short beam is set in the below of waist rail, to form bottom basement form bracing, counterfort is set above waist rail, forms layer second from the bottom or the buttress type braced structures along number second layer basement floor; Be equivalent to arrange the multi-level braced structures to diaphragm wall, and tool buttress type braced structures feature, therefore, can prior art in deep foundation ditch process of construction because diaphragm wall bears the problem that larger pressure easily collapses, have the gear soil that improves diaphragm wall and compression capability, structure simply, the beneficial effect such as easy construction.
2, the utility model adds short beam and counterfort by the diaphragm wall in foundation ditch construction and sidewall of basement, forms a kind of buttress type diaphragm wall supporting and protection structure.This structure can increase the compression capability of diaphragm wall in foundation ditch construction, also plays the effect of reinforcing sidewall of basement wall body structure simultaneously.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Specific embodiment 1
Referring to figs. 1 through Fig. 6, the buttress type supporting and protection structure of the foundation ditch diaphragm wall related in the present embodiment, comprise diaphragm wall 1, in the top of diaphragm wall 1 is arranged, lead wall 3-1, lead wall 3-2 and hat beam 2 outward, hat beam 2 is on the top of diaphragm wall 1 and lead wall 3-1 in being clipped in, lead between wall 3-1 outward; Arrange first at the near coal-mine place of foundation ditch and support 4, described first supports 4 and is fixedly connected with hat beam 2, forms top supporting and protection structure; Bottom foundation ditch, arrange waist rail 5 toward position more than last layer basement height, described waist rail 5 is fixedly connected to form second braced structures, i.e. lumbar support structure with diaphragm wall wall; Short beam 7 is set in the below of waist rail 5, supports to form negative three layers of basement structure 9, counterfort 8 is set above waist rail 5, forms the buttress type braced structures bearing two layers of basement structure 10; Diaphragm wall wall bottom foundation ditch is provided with gutter 6.
In the present embodiment, the thickness of described diaphragm wall 1 is 800mm.The height of described diaphragm wall 1 is the height sum of three layers of basement.After having constructed.Totally three layers of basement structure in foundation ditch, are that basement bears three layer construction 9, the negative two layers of structure 10 of basement and the negative Rotating fields 11 of basement respectively, in addition, foundation ditch have first floor floor slab structure 12.
The construction method of the present embodiment, is characterized in that:
1) first on smooth location, diaphragm wall 1 is carried out in construction, then lead in the construction of the both sides, top of diaphragm wall 1 is carried out wall 3 carry out in lead wall 3-1, lead wall 3-2 outward, then carry out hat beam 2 in the construction of the top of diaphragm wall 1;
2) excavation of foundation pit is carried out to excavation face 13 in layering and zoning, and first construction is carried out first and supported 4, and described first supports 4 and is fixedly connected with hat beam 2, forms top supporting and protection structure; Then bottom foundation ditch, arrange waist rail 5 toward position more than last layer basement height, described waist rail 5 is fixedly connected to form second braced structures, i.e. lumbar support structure with diaphragm wall wall;
3) excavation face-7.2m being excavated to foundation ditch locates, and gutter 6 is carried out in construction;
4) construction is carried out basement and is born three layer construction 9 and basement bears two-layer structure 10, builds simultaneously and supports short beam 7, and construction sidewall of basement to second supports 5 absolute altitude places, the end;
5) remove second braced structures 5, continue up construction basement to first and support 4 end absolute altitudes, and build counterfort 8 simultaneously;
6) finally remove first and support 4, basement is up constructed to a negative Rotating fields 11 and first floor floor 12 place, and backfill sidewall and diaphragm wall space 14, foundation pit construction completes.
Further, between diaphragm wall and sidewall of basement, utilize concrete backfill, make diaphragm wall and sidewall of basement form overall structure.
Owing to strengthening short beam and counterfort between sidewall and continuous body of wall, its continuous body of wall and sidewall of basement overall structure are stronger, can strengthen keeping off native ability, thus strengthen the compression capability of basement and diaphragm wall.
Other specific embodiments:
The feature of other specific embodiments of the utility model is: the height of described diaphragm wall 1 is the height sum of four layers or five layers basement; Short beam 7 is set in the below of waist rail 5, supports to form bottom basement structure, counterfort 8 is set above waist rail 5, form layer second from the bottom or the buttress type braced structures along number second layer basement structure.All the other are with specific embodiment 1.
The above; be only the utility model preferably specific embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with this technician in the scope that the utility model discloses; be equal to according to the technical solution of the utility model and design thereof and replace or change, all belonged to protection domain of the present utility model.The content do not described in detail in the utility model is state of the art scope.
