Abstract

The invention relates to the civil engineering field, especially relating to a temporary drainage method for water-sufficient areas of sandy land. A drainage channel, waterproof films and water stop rivets are adopted in the method. The temporary drainage method also comprises the following four steps. Step one: the drainage channel is dug according to a design drawing, and a reservoir that is connected with the drainage channel is constructed at the far end of the drainage channel. Stop two: the waterproof films are laid in the drainage channel in the water flow direction; at the connecting place of every two films, the edge of the upstream film covers the edge of the downstream film. Step three: the water stop rivets are hammered at the connecting place of every two films; Step four: the films that cover the embankment of the channel are covered with sand. With the design of the invention, for a deep foundation pit project, drained water cannot rapidly permeate back to the construction site through sandy land. After the foundation pit project is finished, backflow of underground water can be ensured after the films are removed, which can protect land quality.

Description

Sand ground abundance of water region temporary drainage method

Technical field

The present invention relates to field of civil engineering, relate in particular to sand ground abundance of water region temporary drainage method.

Background technology

Because iron and steel, the energy, Resources Construction project have some demands in construction and production period to water resource, so region that general building project all can select water resource relatively to enrich, and due to the relation of sand ground geological characteristics, in the time carrying out above-mentioned a few intermediate item construction, there will be the underground deep-foundation pit engineering that the degree of depth is larger, while carrying out such engineering, drainage construction falls, but sand ground draining is without special drainage, the water of discharging can infiltrate very soon in sand ground and flow back to foundation ditch, and the underground water of simultaneously discharging also can cause adverse effect to the shallow foundation hole of closing on excavation.

Summary of the invention

The object of the invention is to, provide a kind of and reuse, place the Groundwater of discharging and can return the original former groundwater resources of underground maintenance and the impregnable sand ground abundance of water of environment region temporary drainage method.

In order to achieve the above object, the present invention is achieved in that

A kind of sand ground abundance of water region temporary drainage method, it comprises escape canal, fluid-tight film and sealing rivet; Also comprise the steps:

Step 1, press design drawing excavation escape canal, and at the distant place of escape canal terminal arranges and escape canal links reservoir;

Step 2, at the fluid-tight film of escape canal laid inside, film is laid along the direction of current direction, each film joint hides the edge of downstream membrane with the edge of upstream film;

Step 3, hammer into sealing rivet in the joint of each film;

Step 4, on the film being covered on irrigation canals and ditches embankment, cover sandy soil.

Described sand ground abundance of water region temporary drainage method, fluid-tight film is colour bar cloth or plastic foil.

Described sand ground abundance of water region temporary drainage method, sealing rivet comprises the nail bar of plastic material and the head of a nail of quality of rubber materials.

The present invention adopts above-mentioned design, after underground water is got rid of, deep foundation pit construction place and contiguous construction area just can not be subject to discharging the impact of rear a large amount of underground water, and the water in reservoir also can permeate the ground gradually and spread gradually towards periphery, after having constructed, falling draining stops, Groundwater infiltration sand ground, reclaims waterproof film in irrigation canals and ditches, the backfill of sand ground excavation part, completed deep foundation pit construction, made again the water and soil resources of sand ground not be affected.

Fig. 2 is arrangement diagram of the present invention.

Fig. 3 is the structural representation of sealing rivet.

Detailed description of the invention

As shown in Figure 1 and Figure 2, a kind of sand ground abundance of water region temporary drainage method, it comprises escape canal 1, plastic sheeting 2 and sealing rivet 3; Also comprise the steps:

Step 1, press design drawing excavation escape canal 1, and the reservoir 4 linking at the terminal setting of the distant place of escape canal 1 and escape canal 1;

Step 2, at escape canal 1 laid inside plastic sheeting 2, plastic sheeting 2 is laid along the direction of current direction, the edge of covering downstream, the edge plastic sheeting 2 of upstream plastic sheetings 2 for each plastic sheeting 2 joints;

Step 3, hammer into sealing rivet 3 in the joint of each plastic sheeting 2;

Step 4, on the plastic sheeting 2 being covered on irrigation canals and ditches 1 embankment, cover sandy soil.

Described sand ground abundance of water region temporary drainage method, plastic sheeting 2 can also use colour bar cloth to substitute.

As shown in Figure 3, for ensureing the effect of sealing rivet 3, sealing rivet 3 comprises the nail bar 32 of plastic material and the head of a nail 31 of quality of rubber materials.
