Abstract
The invention relates to the technical field of earth retaining and water drainage and discloses a novel retaining plate reverse-filtering drainage system and a construction method. The construction method includes: pouring a concrete base layer of a reverse-filtering layer; laying a drainage net core on the reverse-filtering layer; building an earth retaining wall; filling and building a gravel layer, and laying a nonwoven water isolating layer till a wall top; pre-burying a water collection pipe and a water discharge pipe at the bottom, and connecting the same by adopting a three-way connector; extending the drainage net core into an open groove of the water collection pipe; pouring a top platform or backfilling clay at the top to cut off ground water. The novel retaining wall reverse-filtering drainage system is short in construction time and has a good drainage function and certain strength, blockage of a drainage passage due to the fact that concrete intrudes into a reverse-filtering drainage structure during concrete pouring is avoided, and drainage effect is guaranteed.

Loaded filter, as the important component part of retaining structure, is stablized to maintain barricade for getting rid of wall back of the body soil body ponding, and running off in generation seepage failure etc. preventing the soil body all plays an important role.In the design and construction process of retaining structure, engineers and technicians often attach great importance to the main part of retaining structure, and design and the detailed inspection of having carried out system are calculated, and pay close attention to not to loaded filter, do not carry out the design of autonomous system.
In prior art, what loaded filter generally adopted is bagged sand gravel.In the design and construction process of reality, mainly there is the deficiency of the following aspects in bagged sand gravel loaded filter:
(1) engineering time is longer, and the loaded filter construction in excavation location is after soil excavation completes, and in wall back of the body place, code block forms from bottom to top, takes longer, easily causes interim excavation slope to produce local buckling because open-assembly time is longer;
(2) difficulty of construction is large, and because wall back slope rate is comparatively steep or even upright, and loaded filter thickness is relatively thin, and the difficulty that code builds construction is comparatively large, and particularly when barricade is higher, self-stability is poor, is more difficult to construction;
(3) construction quality is wayward, because loaded filter is relatively thin, the wall back of the body also out-of-flatness that excavation is formed, and design is also without clear and definite compactness standard-required, the loaded filter that code is built generally is difficult to closely knit and uneven thickness, affects the performance of its anti-filter, drain function;
(4) reliable quality determining method is lacked.
Summary of the invention
The invention provides a kind of novel barricade anti-filter drainage system and construction method, to solve in prior art the loaded filter engineering time compared with long, difficulty of construction is large, the uppity technical problem of quality.
The object of the invention is to be achieved through the following technical solutions:
A novel barricade anti-filter drainage and construction method, comprising:
Build the concrete base layer of loaded filter;
Draining web-roll core is routed on loaded filter;
