The structure comprises a continuous retaining wall formed by a plurality of supporting wallboards, wherein a longitudinal rib plate is arranged near the edge on one side outside each supporting wallboard; and the supporting wallboards and the longitudinal rib plates jointly form a rigid whole. The structure has the following advantages: the problems of poor bearing capacity, inconvenience in construction, high construction cost and the like in the prior art are solved; and the structure has the characteristics of reasonable structure, convenience in construction, low construction cost, good protection effect and the like, and can be used for foundation pit or slope support.
Description
Technical field
The utility model relates to the retaining support technical field of structures, more particularly, relates in particular to a kind of L type retaining wall structure.
Background technology
Present foundation pit supporting system: the flexible support system is mainly anchor pole+sprayed mortar net muscle surface layer form; The stake of rigidity support form or ground-connecting-wall+support or anchor cable.Flexible support system cost is low, but the displacement control ability is poor, and cutting depth is limited.And rigidity support system cost is high, but it is strong to control the peripheral distortion ability, and cutting depth is big.Bigger in the excavation of foundation pit degree of depth, environment soil layer mechanical property of living in is relatively poor, under the situation of surrounding enviroment sternness, all adopts stake (or ground-connecting-wall)+interior support (or anchor cable) support system usually.
Stake (or ground-connecting-wall)+interior supporting system has following deficiency: 1, the concrete support needs molding, mounting reinforcing steel bars, fluid concrete etc., needs the long construction period; Need remove support again during construction in later period basement agent structure, need the manpower and materials of labor, and can produce airborne dust, contaminated environment.If 2 adopt steel to support, then need large-scale equipment to lift.And steel is supported for on-site consolidation, and globality is not strong, and system is unstable, is very easy to cause the foundation ditch malicious event that caves in, and destroys that periphery is built, structure, brings huge property loss, causes the serious social influence of giving.3, because after the excavation of foundation pit degree of depth increases, under a lot of situation of main duration of construction foundation pit by the construction of supporting with remove and confirm that adopting inner supporting body is can prolong much the foundation ditch duration.4, because interior support has taken the inner space of excavation of foundation pit, hinder the operation of construction machinery, cause pit earthwork excavation and later stage basement main structure construction inconvenience.
Stake (or ground-connecting-wall)+cable bolting system has following deficiency: 1. existing support system anchor cable system is a stage excavation, and gradation sets.In the work progress, anchor cable needs boring, system anchor, cast anchor, be in the milk, wait for fixed attention process such as phase, long construction period.2. in the construction anchor cable process, it is bigger to set length, and the surrounding enviroment influence basin is bigger, and particularly present city foundation ditch exists a large amount of municipal pipelines, construction of structures basis, subway tunnel etc. in the certain limit.Under the surrounding enviroment complicated situation, set anchor cable and may destroy construction of structures, therefore also limited the use of anchor cable in a large number.3. if be the soil layer anchor cable, anchor cable is owing to the creep of the soil body, and the displacement meeting of cable bolting system constantly increases, and causes support system dangerous situation to occur.4. perforate sets anchor cable in layer of sand, also can take a large amount of Sha Heshui out of, and cause land subsidence etc., has a strong impact on the safety of foundation pit supporting system and surrounding enviroment.
Present side slope pile-anchor supporting system because the creep effect of soil layer anchor cable brings dangerous situation can for permanent use of side slope, has also limited its use.
