Embodiment:
Anti-floating design is a requisite project for underground engineering construction, its structure, the problems such as quality directly affect the safety of surface construction, continuous quickening along with Urbanization in China, the development and use of urban underground space also are subjected to the attention of all departments increasingly, at present, more underground construction anti-floating commonly used adopts and adds Guan Liang between agent structure 1 and the supporting and protection structure 2 and capping beam 3 solves, wherein, the construction of Guan Liang need be through cutting pile crown, abolishing the dabbing of face processes, the scum silica frost cleaning, the straightening reserved steel bar, formwork erection is built, the steps such as form removal maintenance, after with the method Guan Liang being set, between agent structure 1 and hat beam, build capping beam 3 again, in the work progress that adopts the method, no matter be that Guan Liang or the difficulty of construction of capping beam 3 are all larger, because the continuous volume of Guan Liang is large, capping beam 3 construction spaces are little, when choosing outside the Guan Liang, construction space is narrow and small, and the interface processing difficulty is large, and quality also is difficult to ensure card; And when Guan Liang chooses outside not, capping beam 3 also needs reliably to be connected with supporting and protection structure 2, because all can there be a lot of drawbacks in early stage embedded ribs or later stage bar planting etc., tend to batch interface to occur connecing difficult, reinforcing bar connects the large difficulty that waits of difficulty, therefore, for simplifying the difficulty of construction of said structure, the utility model proposes a kind of foundation ditch float Structure for underground construction, as shown in Figure 1, it comprises is located at the supporting and protection structure 2 that is used for going along with sb. to guard him agent structure 1 in the foundation ditch, described supporting and protection structure 2 is located at agent structure 1 one sides, be provided with anchoring piece between supporting and protection structure 2 and the agent structure 1, solve the inconvenience that Guan Liang and capping beam 3 are constructed and caused continuously, removed the complicated procedures of forming of Guan Liang construction from, reduced construction cost.
In the Anti-floating design of underground construction, Guan Liang generally is used for the stake top of foundation pit supporting construction 2, make many piles top have elastic restraint, strengthen the stability of pile body integral body, capping beam 3 then is usually used on the masonry member, as: enclosure wall, adopt the solidifying soil of concrete or reinforcing bar to build, other reinforced concrete member reinforcing bars on enhancing masonry monolithic stability or anchoring are beared down on one, the utility model passes through appropriate design, take full advantage of the effect of capping beam 3, adopt anchoring piece to replace the continuous constructure scheme of Guan Liang and capping beam 3, described anchoring piece adopts as shown in Figure 2 structure, as shown in Figure 2, anchoring piece is by capping beam 3 and is located at the integrative-structure that the support pier 4 on the capping beam 3 forms, wherein, capping beam 3 has the continuous effect of Guan Liang concurrently, support pier 4 can satisfy the stressed needs of support at foundation ditch top, capping beam 3 is connected on the supporting and protection structure 2, its syndeton is as follows: such as Fig. 3, shown in Figure 4, top in supporting and protection structure 2 is provided with dowel, one end of capping beam 3 is connected with supporting and protection structure 2 by dowel, closely knit by building between the other end of capping beam 3 and the agent structure 1, be provided with support pier 4 on the top of capping beam 3, the foundation ditch that is provided with for foundation pit construction at support pier 4 supports 5.
For better realizing the utility model, support pier 4 all forms by reinforcing bar binding with capping beam 3, and is simple in structure, after can first support pier 4 and capping beam 3 configurations being finished, carry out again foundation pit construction, easier than building the method for capping beam 3 at Guan Liang in the prior art, reduced difficulty of construction; Certainly, support pier 4 and capping beam 3, supporting and protection structure 2 and capping beam 3 to connect batch position also all closely knit by building, firm in structure, make it have good anti-floating ability; And in the utility model, capping beam 3 also comprises the outer part of choosing, and is certain, and its outer part of choosing should satisfy the fastness of self and certain degree of depth restriction, and the bottom of choosing part outward then is by wiping one's face or the handled flat configuration of clay model; On support pier 4, also be provided be used to burying foundation ditch underground and support 5 required iron plates, in practice of construction, should in time bury underground, prop up again afterwards vertical foundation ditch and support 5 template.
In the practice of construction process, because the difference of construction site, supporting and protection structure 2 is to some extent difference also, and supporting and protection structure 2 described in the utility model can be made as maintaining pile (as: bored pile, reinforced concrete sheet pile etc.) or safeguard wall (as: diaphragm wall, soil nail wall etc.).
But supporting and protection structure 2 one-shot formings that the utility model adopts, and be simple and easy to do, simplified the support force structure, make the anti-floating coping structure be easier to operation, more be tending towards safe and reliable, its Specific construction step is as follows:
(1) construction of supporting and protection structure 2: carry out engineering calculation (structural calculation of each several part) according to the practice of construction place, after structural calculation is passed through, in foundation ditch, set up fender post or enclosure wall, and reserve the dowel of itself and capping beam 3 by designing requirement.
(2) construction of anchoring piece (capping beam 3 and support pier 4): colligation capping beam 3 and support pier 4 reinforcing bars on dowel, support 5 required ironwares as burying foundation ditch on the support pier 4 underground, should in time bury underground, branching standing template afterwards, capping beam 3 is outer to be chosen the part bottom and can adopt and wipe one's face or the measure such as clay model guarantees its planeness, build capping beam 3 concrete, control building blanking time of itself and support pier 4, guarantee to connect that build continuously at a batch position, vibration compacting.
(3) support system of anchoring piece: build until capping beam 3 and support pier 4 and to finish and after maintenance reaches the intensity of designing requirement, carry out foundation pit construction, add foundation ditch at support pier 4 and support 5, when later stage agent structure 1 construction, can directly utilize capping beam 3, only notice that 1 of capping beam 3 times and agent structure are built closely knitly both can.
The utility model is with low cost, and technique is simple, and quality is easy to the advantages such as control, has overcome the problems such as above-mentioned, has simplified the support force structure, makes the anti-floating coping structure be easier to operation, more is tending towards safe and reliable.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all falls within the protection domain of the present utility model any simple modification, equivalent variations that above embodiment does.
