Abstract
Disclosed are an anti-seepage wall and a construction method thereof. The anti-seepage wall comprises multiple anti-seepage plate sections which are movably connected. Each anti-seepage plate section is an anticorrosion plastic plate and comprises a main plate, a connecting fold edge and a connecting fold lug, the connecting fold edge and the connecting fold lug are disposed on two sides of the main plate, and a pile machine formwork mounting groove is arranged at the bottom of the main plate. Two adjacent anti-seepage plate sections are movably connected in a wedge manner, namely the connecting fold edge of the rear anti-seepage plate section is inserted into the connecting fold lug of the front anti-seepage plate section. The anti-seepage wall is simple in structure, convenient to construct, low in manufacturing cost, made of super-corrosion-resistant materials such as polyethylene or polypropylene, quite long in service life, high in cost performance, suitable for soil dams of reservoirs of rivers, lakes and the sea and suitable for anti-seepage treatment of soil buildings. In addition, due to the fact that the anti-seepage plate sections are movably connected, the anti-seepage wall is high in deformability to adapt to soil stress, and crack accidents can be avoided.

Detailed description of the invention
A kind of impervious wall as shown in Figure 1, be flexibly connected by more piece barrier sheet and form, described barrier sheet is anti-rot plastic plate, as shown in Figures 2 and 3, barrier sheet rolls over ear 3 with the connection flanging 2 being located at mainboard both sides with being connected by mainboard 1, is provided with a machine template and mounts groove 4 bottom mainboard 1.
Barrier sheet of the present invention is flexibly connected and refers to that adjacent two joint barrier sheets are that wedging connects, and namely, the connection flanging of a joint barrier sheet is plugged in the connection folding ear of last joint barrier sheet.
It can also be other forms of flexible connection such as adjacent two joint barrier sheet clamping or sockets etc. that barrier sheet of the present invention is flexibly connected.
Barrier sheet of the present invention is polyethylene board or polypropylene board or polyvinyl chloride panel, or the anti-rot plastic plate of other materials.
The construction method of impervious wall, comprises the following steps: a., according to the actual conditions of sub-bottom changes, determines to build the position of design impervious wall and the degree of depth and trend thereof; B. stake machine template is inserted barrier sheet, make together with a machine template stacks with barrier sheet, the stake machine template making a bottom of machine template fall into barrier sheet mounts in groove, gapless between barrier sheet and stake machine template contacts face; C. by stake machine model sheetinstallat on stake machine; D. a machine pile monkey is then started to the vibration pressure of stake machine template one along barrier sheet direction, stake machine template drives barrier sheet to be sunk in the dykes and dams soil body, and when sinkage reaches designing requirement, stake machine stops vibration, extract a machine template, first segment barrier sheet is just stayed to be needed in the dykes and dams soil body of antiseepage; E. stake machine template is inserted second section barrier sheet, make together with a machine template stacks with second section barrier sheet, the stake machine template making a bottom of machine template fall into barrier sheet mounts in groove, gapless between barrier sheet and stake machine template contacts face, and make the connection flanging of second section barrier sheet insert in the connection folding ear of first segment barrier sheet; F. by stake machine model sheetinstallat on stake machine, then a machine pile monkey is started to the vibration pressure of stake machine template one along barrier sheet direction, stake machine template drives barrier sheet to be sunk in the dykes and dams soil body, when sinkage reaches designing requirement, stake machine stops vibration, extract a machine template, second section barrier sheet just connects as one with first segment barrier sheet, stays simultaneously and needs in the dykes and dams soil body of antiseepage; G. according to designing requirement, then sink to Section of three barrier sheet, its method is identical with the method sinking to second section barrier sheet, and such three joint barrier sheets are interconnected to be integrated to be stayed in the soil body; H. the method that sinks to of Section of three barrier sheet and barrier sheet below all with second section barrier sheet to sink to method identical, according to designing requirement, can sink to and save barrier sheet arbitrarily, in the soil body, bury random length underground, any degree of depth, the impervious wall connected as one by more piece barrier sheet; I. for ensureing the verticality of stake machine template, double-shaft tilt angle sensor is utilized to measure and control technology, be arranged on a machine template top by obliquity sensor, obliquity sensor is electrically connected with stake machine control system, makes it keep vertically sinking to by stake machine control system regulable control stake machine template.
Engineering design requirements and trend thereof is built according to impervious wall, the selected position burying first segment barrier sheet underground, as the starting point of impervious wall, as shown in Figure 4 and Figure 5, then together with barrier sheet being stacked with stake machine template 5, simultaneously, the bottom of stake machine template is dropped on a machine template and is mounted in groove, again with magnet on the mainboard of barrier sheet give barrier sheet certain pressure, to reaching gapless between barrier sheet and stake machine template contacts face, the connection flanging of adjacent two joint barrier sheets is kept to roll over the correct wedging of ear with being connected.Then a machine pile monkey is started, repeatedly give stake machine template with vibration pressure along barrier sheet direction, namely stake machine template is sunk in the soil body, when sinkage reaches designing requirement, namely stop pile monkey vibration, under the effect of stake machine, stake machine template is extracted from the soil body, at this moment first segment barrier sheet is left in the soil body, and first segment impervious wall is buried underground successfully.In work progress, the measurement of double-shaft tilt angle sensor and control technology must be utilized to ensure the verticality of stake machine template.Second section barrier sheet method for embedding, except identical with first segment method for embedding, also will pay special attention to make the connection flanging of second section barrier sheet correctly wedge the connection folding ear of first segment barrier sheet, first segment barrier sheet and second section barrier sheet are formed, and wedging type is active to be connected.Simultaneously under pile monkey vibration, second section barrier sheet is sunk in the soil body, connects as one with first segment impervious wall.Section three, the method for embedding of barrier sheet and below more piece barrier sheet is identical with the method for embedding of second section barrier sheet.Can according to designing requirement, bury three joints, four joints or more more piece barrier sheet underground, barrier sheet is interconnected to constitute the impervious wall that random length is integrated continuously.
