Description
Technical field
The utility model relates to foundation pit earth laminated structure applied technical field, especially a kind of foundation pit earth pressure-controlled structure.
Background technology
The foundation excavation of silt large for some excavation areas, the degree of depth is little again, adopts in foundation ditch and is abound with the support cost that the design of horizontal inner support can increase foundation ditch undoubtedly greatly.Engineering practice shows, utilizes the remaining soils of foundation ditch inside and diagonal brace to assist the design and construction carrying out foundation ditch, can reduce support cost.
For these actual conditions of foundation ditch that area is larger, being abound with reinforced concrete inner support system if adopted, to encircle for protection greatly increasing foundation ditch the cost of engineering undoubtedly, and developer being in order to make full use of soil, foundation ditch surrounding headspace is greatly reduced, puts slope mode so often also cannot adopt.For solving this ~ problem, when carrying out large-scale excavation excavation, when conditions permit, adopt the mode of reserved soil in foundation ditch to carry out mode that design of foundation pit and construction are a kind of economical rationality.
Prior art can not meet the needs of people, and for making up prior art deficiency, the utility model aims to provide a kind of foundation pit earth pressure-controlled structure.
For achieving the above object, the utility model is by the following technical solutions: a kind of foundation pit earth pressure-controlled structure, at least comprises base plate cushion cap, timber, basement bottom board, support bracket, capping beam, built-in fitting, steel pipe skewed horizontal load part, B1 floor and concrete bracket; Described timber is arranged on base plate cushion cap left end; Described base plate cushion cap upper end is provided with concrete bracket; Described B1 floor left end is connected with load transfering strip; On the right side of described steel pipe skewed horizontal load part, bottom and concrete bracket overlap, and left upper end is connected with capping beam by built-in fitting; Described basement bottom board left end left end is connected with conveyer belt.
Further, described steel pipe skewed horizontal load part is when making: after basement bottom board and bracket reach 80% of design strength, can carry out Two bors d's oeuveres 0609mm steel pipe support and install.Measure bracing members installed height mark and horizontal level, the concrete laitance on the pre-embedded steel slab on capping beam and base plate is cleaned out, measure the clear spacing of pre-embedded steel slab between capping beam and underplate concrete bracket, adjust assembled bearing length.Through review errorless after, then steel end wall bracket is set on bracket, carries out welding procedure.For ensureing base pit stability, should be installed by most weak spot, namely carrying out welding procedure from middle part, limit, hole to both sides.
Compared with prior art, the beneficial effects of the utility model are: this foundation pit earth pressure-controlled structure, the foundation excavation of silt large for some excavation areas, the degree of depth is little again, adopt in foundation ditch and are abound with the support cost that the design of horizontal inner support can increase foundation ditch undoubtedly greatly; Engineering practice shows, utilizes the remaining soils of foundation ditch inside and diagonal brace to assist the design and construction carrying out foundation ditch, can reduce support cost.Overall structure is simple, practical, easily manufactured, is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of foundation pit earth pressure-controlled structure, at least comprises base plate cushion cap 1, timber 2, basement bottom board 3, support bracket 4, capping beam 5, built-in fitting 6, steel pipe skewed horizontal load part 7, B1 floor 8 and concrete bracket 9; Described timber 2 is arranged on base plate cushion cap 1 left end; Described base plate cushion cap 1 upper end is provided with concrete bracket 9; Described B1 floor 8 left end is connected with load transfering strip; On the right side of described steel pipe skewed horizontal load part 7, bottom and concrete bracket 9 overlap, and left upper end is connected with capping beam 5 by built-in fitting 6; Described basement bottom board 3 left end left end is connected with conveyer belt.
Further, described steel pipe skewed horizontal load part 7 is when making: after basement bottom board and bracket reach 80% of design strength, can carry out Two bors d's oeuveres 0609mm steel pipe support and install.Measure bracing members installed height mark and horizontal level, the concrete laitance on the pre-embedded steel slab on capping beam and base plate is cleaned out, measure the clear spacing of pre-embedded steel slab between capping beam and underplate concrete bracket, adjust assembled bearing length.Through review errorless after, then steel end wall bracket is set on bracket, carries out welding procedure.For ensureing base pit stability, should be installed by most weak spot, namely carrying out welding procedure from middle part, limit, hole to both sides.
After basement bottom board and bracket reach 80% of design strength, Two bors d's oeuveres 0609mm steel pipe support can be carried out and install.Measure bracing members installed height mark and horizontal level, the concrete laitance on the pre-embedded steel slab on capping beam and base plate is cleaned out, measure the clear spacing of pre-embedded steel slab between capping beam and underplate concrete bracket, adjust assembled bearing length.Through review errorless after, then steel end wall bracket is set on bracket, carries out welding procedure.
For ensureing base pit stability, should be installed by most weak spot, namely carrying out welding procedure from middle part, limit, hole to both sides.In capping beam work progress, the location of built-in fitting must accurately, and this engineering controls according to deviation < 5mm.Consider pressure Xiang Liang at the scene in work progress likely because built-in fitting causes relatively large off normal, so in the work progress of follow-up bracket, require that measuring personnel should locate the relative position of diagonal brace bracket according to the position of pressure item beam built-in fitting, to ensure to press the built-in fitting in Xiang Liang and bracket to keep just to state.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
