Abstract

The invention discloses the soft base processing methods that drainage channel is closed in a kind of application timing, this soft base processing method is coated with corrosion medicine slurry on the drain bar for forming vertical drain inside soft base, the water and vapour inside soft base are discharged by drain bar during treatment of soft foundation, the filter membrane of drain bar is slowly corroded after corrosion medicine slurry contact water, filter membrane etching time is subscribed by corroding the setting of medicine slurry concentration, achieve the effect that periodically to close vertical drain, to save treatment of soft foundation project amount, effectively save cost, the invention is used for treatment of soft foundation engineering field.

Description

The soft base processing method of drainage channel is closed in a kind of application timing

Technical field

The present invention relates to treatment of soft foundation engineering fields, close at the soft base of drainage channel more particularly to a kind of application timing Reason method.

Background technique

During treatment of soft foundation, it is desirable that the water and vapour that can quickly be discharged in mud improves the void ratio in mud, usually During treatment of soft foundation, vertical drain can be arranged to be discharged in mud water and vapour.After treatment of soft foundation, in order to anti- The discharge that continues of sealing and vapour leads to that treated settlement after construction occurs for soft base, it usually needs cuts vertical row by mechanical device Aquaporin prevents settlement after construction from continuing to occur, so that treatment of soft foundation operation meets requirement.

And the existing way that vertical drain is cut by mechanical device, biggish project amount is needed, and expend machine Tool and manpower, the cost that will lead to treatment of soft foundation operation increase.

Summary of the invention

The purpose of the present invention is to provide one kind to automatically cut off vertical drain by presetting to save at soft base The soft base processing method of drainage channel is closed in the application timing for managing cost.

The technical solution used in the present invention is:

The soft base processing method of drainage channel is closed in a kind of application timing, comprising the following steps:

1) the corrosion medicine slurry of the filter membrane of corrosion drain bar, is configured to according to the default channel shut-in time；

2), in the corrosion medicine slurry of the filter membrane coating predetermined depth of drain bar；

3), drain bar is inserted vertically into soft base to be processed, and drain bar is inserted into preset treatment of soft foundation depth, is formed Vertical drain during treatment of soft foundation；

4), carry out treatment of soft foundation operation, in treatment of soft foundation operation process by drain bar be discharged water in soft base mud with Vapour, meanwhile, corrosion medicine slurry is chemically reacted with water, corrodes the filter membrane of drain bar；

5), after the filter membrane corrosion of drain bar, mud penetrates into drain bar, closes vertical drain.

It is further used as the improvement of technical solution of the present invention, and drain bar includes the filter for draining inner core and package draining inner core Film, draining inner core includes the plastic plate of a strip and vertical several rhones disposed in parallel on plastic plate.

It is further used as the improvement of technical solution of the present invention, and in step 5), after filter membrane corrodes, mud penetrates into rhone It is interior, vertical drain is blocked, realizes the closing to vertical drain.

It is further used as the improvement of technical solution of the present invention, and the predetermined depth of the corrosion medicine slurry coated in step 2) is 50cm。

It is further used as the improvement of technical solution of the present invention, and the etching time of filter membrane is in 1 month.

Beneficial effects of the present invention: this application timing closes the soft base processing method of drainage channel through shape inside soft base At corrosion medicine slurry is coated on the drain bar of vertical drain, the water inside soft base is discharged by drain bar during treatment of soft foundation And vapour, corrosion medicine slurry are slowly corroded the filter membrane of drain bar after contacting water, are subscribed by corroding the setting of medicine slurry concentration Filter membrane etching time achievees the effect that periodically to close vertical drain, to save treatment of soft foundation project amount, effectively Save cost.

Specific embodiment

The present invention is a kind of soft base processing method of application timing closing drainage channel, comprising the following steps:

2) the corrosion medicine slurry of predetermined depth, is coated on the filter membrane of drain bar；

The soft base processing method that drainage channel is closed in this application timing is forming vertical drain inside soft base It is coated with corrosion medicine slurry on drain bar, the water and vapour inside soft base are discharged by drain bar during treatment of soft foundation, corrosion medicine slurry connects The filter membrane of drain bar is slowly corroded after touching water, filter membrane etching time is subscribed by corroding the setting of medicine slurry concentration, reaches To the effect that can be periodically closed to vertical drain, to save treatment of soft foundation project amount, cost is effectively saved.

As a preferred embodiment of the present invention, drain bar includes the filter membrane for draining inner core and package draining inner core, draining Inner core includes the plastic plate of a strip and vertical several rhones disposed in parallel on plastic plate.

As a preferred embodiment of the present invention, in step 5), after filter membrane corrodes, mud penetrates into rhone, resistance Disconnected vertical drain, realizes the closing to vertical drain.

As a preferred embodiment of the present invention, the predetermined depth of the corrosion medicine slurry coated in step 2) is 50cm.

Drain bar is made of plastic plate or degradable material, in preheating setting time, after filter membrane is corroded, and draining Slot is filled by mud, so that effectively blocking rhone forms closing.

As a preferred embodiment of the present invention, the etching time of filter membrane is in 1 month.

Certainly, the invention is not limited to above embodiment, and those skilled in the art are without prejudice to originally Equivalent deformation or replacement can be also made under the premise of spirit, these equivalent variation or replacement are all contained in the application right It is required that in limited range.
