Abstract
The utility model relates to a reinforcing structure for a gate dam foundation of a deep riverbed covering layer. The reinforcing structure mainly aims to solve the technical problem of providing the reinforcing structure for the gate dam foundation of the deep riverbed covering layer and giving the construction method of the structure. The utility model aims to ensure that the sedimentation and the deformation of upper hydraulic structure are within the acceptable range so as to guarantee the safety of the engineering. The technical scheme for solving the problem is as follows: the structure is built above the deep and natural riverbed covering layer, a aerial sandy gravel layer and a floury soil layer on the superficial surface of the deep covering layer are replaced by backfill material, and a consolidation grouting hole is arranged in the backfill material. The reinforcing structure is suitable for the foundation reinforcing treatment when the hydraulic structure such as dams, water gates and the like are built on the deep riverbed covering layer in the water conservancy and hydropower engineering.
Description
Technical field
The utility model relates to a kind of ground stabilization structure, the ruggedized construction of particularly a kind of riverbed deep covering layer gate dam foundation, and the underpin when being applicable to hydraulic structures such as building dam, sluice in the Hydraulic and Hydro-Power Engineering on the riverbed deep covering layer is handled.
Background technology
According to natural conditions such as basin characteristics, topographic and geologics, the engineering of building barrage on deep covering layer is more and more, if the hydraulic structure that concrete dam, sluice etc. are had relatively high expectations to the basis is directly built on the natural stream channel covering layer, often is difficult to satisfy bearing capacity, distortion and seepage stability requirement.Therefore, need in conjunction with the design feature of top hydraulic structure, select safe, reasonable, economical underpin structure and reinforcing and processing method simultaneously according to the physico-mechanical properties of tectal layer of structure distribution, bed thickness and each level.
Summary of the invention
The technical problems to be solved in the utility model is: need have the situation of building hydraulic structures such as gate dam on the riverbed of deep covering layer at this, the ruggedized construction of a kind of riverbed deep covering layer gate dam foundation is provided, and provide the job practices of this structure.Be intended to guarantee top water conservancy project building settlement, distortion in allowed band, thereby guarantee engineering safety.
The technical scheme that the utility model adopted is: the ruggedized construction of a kind of riverbed deep covering layer gate dam foundation, this structure is built on the natural stream channel deep covering layer, it is characterized in that: the built on stilts sand pebble layer and the powder soil horizon of the shallow table of described deep covering layer are replaced by backfill, are provided with the consolidation grouting hole in the backfill.
Described backfill is sandy gravel or rock ballast material.
The beneficial effects of the utility model are: the utility model is excavated the displacement of back employing backfill with the built on stilts sand pebble layer and the powder soil horizon of the shallow table of riverbed deep covering layer, and backfill is carried out layered rolling and consolidation grouting handle, basic tectal supporting capacity and comprehensive deformation modulus have been improved effectively, reduce the sedimentation and deformation of top gate dam structure, guarantee the normal operation of engineering; And this structure helps mechanized construction.
Description of drawings
Fig. 1 is the main sectional view before the riverbed underpin is handled among the utility model embodiment.
Fig. 2 is that the riverbed underpin is finished dealing with and lock chamber is built structural representation after finishing among the utility model embodiment.
The specific embodiment
As shown in Figure 1 and Figure 2, present embodiment will be built sluice having on the riverbed of deep covering layer.If sluice is directly built on the riverbed covering layer, be difficult to satisfy bearing capacity, distortion and infiltration requirement, so present embodiment has carried out consolidation process to this basis, riverbed, its method is as follows:
A. planning to build the position of making sluice, the built on stilts sand pebble layer 1 and the powder soil horizon 2 of deep covering layer shallow table in riverbed in this position range are being excavated;
B. adopt backfill 3 (for sandy gravel or the rock ballast material that has grating to require) backfill displacement then, and the backfill 3 of displacement needs to adopt self-propelled vibrating roller layered rolling;
Consolidation grouting hole 4 is set in backfill 3 after c. backfill is finished, carries out consolidation grouting and handle.
Can carry out the construction of gate floor 6 and lock chamber 5 after consolidation process is finished, and then finish the construction of whole sluice.The step that above-mentioned consolidation grouting is handled can guarantee that backfill 3 contacts with the good of top gate floor 6.
Therefore present embodiment is after the consolidation process of above-mentioned steps a～c, and the built on stilts sand pebble layer 1 of the shallow table of deep covering layer and powder soil horizon 2 are used consolidation grouting hole 4 consolidation process by backfill 3 displacements in the backfill.
Claims (2)
