Fig. 1 is the sectional view of this utility model hydraulic-driven movable dam fluid pressure line laying structure embodiment, the hydraulic-driven movable dam fluid pressure line laying structure of the present embodiment as shown in Figure 1, including the laying ditch 1 being arranged on dam foundation base plate, fluid pressure line 2, solid-filling medium 3 and second phase cast-in-place concrete capping 4, such as, dam foundation base plate can use C25 reinforced concrete, second phase cast-in-place concrete capping 4 can be C30 second phase concrete, and wherein concrete is the abbreviation of concrete.
Wherein second phase cast-in-place concrete capping 4 can cover laying ditch 1, and collectively forms airtight chamber with laying ditch 1, and fluid pressure line 2 is arranged in airtight chamber.Before the second phase, ditch 1 was laid in cast-in-place concrete capping 4 covering, remaining space in the airtight chamber needing to fill up solid-filling medium 3 second phase cast-in-place concrete capping 4 and lay that ditch 1 formed, say, that remove the space that second phase cast-in-place concrete covers 4 spaces that may take and fluid pressure line 2 takies.
In order to when the situation that section hydraulic pipeline 2 damages occurs, the fluid pressure line 2 damaged can be keeped in repair or changes, in the present embodiment, solid-filling medium 3 is used to take the certain space laying ditch 1, such that it is able to that is done by the thickness of second phase cast-in-place concrete capping 4 accordingly is relatively thin, second phase cast-in-place concrete capping 4 is the most easily made to be destroyed.Owing to fluid pressure line 2 can be covered by solid-filling medium 3, therefore solid-filling medium 3 is also required to can be disassembled the most easily or destroy, so needing solid-filling medium 3 to constitute disassembled interstitital texture in airtight chamber, afterwards, need to be tightly connected second phase cast-in-place concrete capping 4 with laying ditch 1.Specifically, second phase cast-in-place concrete capping 4 can directly use the method poured, pour on solid-filling medium 3 after having filled solid-filling medium 3, ultimately forms second phase cast-in-place concrete capping 4.
The hydraulic-driven movable dam fluid pressure line laying structure of the present embodiment, by filling solid-filling medium 3 at laying ditch 1, and constitute disassembled interstitital texture, avoid in the laying ditch 1 that fluid pressure line 2 is covered on dam foundation base plate by the method utilizing cast-in-place concrete to pour, achieve the thickness reducing second phase cast-in-place concrete capping 4, and when the situation of section hydraulic conduit failure occurs, second phase cast-in-place concrete capping 4 is easier to be destroyed, and avoids and damage fluid pressure line 2 during rejecting second phase cast-in-place concrete capping 4.Use the technical scheme of the present embodiment, it is possible to when the situation that section hydraulic pipeline 2 damages occurs, conveniently and efficiently the fluid pressure line 2 damaged is keeped in repair or changes, save fluid pressure line 2 and keep in repair or replacing construction, improve efficiency.Simultaneously it can be avoided that pouring concrete capping 4 is washed away by current, cause solid-filling medium between second phase cast-in-place concrete 4 times fluid pressure lines of capping to come off, make fluid pressure line 2 directly contact with current and by heavy corrosion.
In order to prevent penetrating into more water in laying ditch 1, the hydraulic-driven movable dam of the present embodiment is with in fluid pressure line laying structure, and fixing filled media 3 can include the low-grade concrete that water penetration is poor, such as C5 or C10.But during hydraulic pump carries liquid by fluid pressure line 2, fluid pressure line 2 may shake, the damping effect of low-grade concrete is poor, and after rejecting second phase cast-in-place concrete capping 4, low-grade concrete cleaning the most relatively difficulty, therefore, in order to solve the problems referred to above, the hydraulic-driven movable dam of the present embodiment is with in fluid pressure line laying structure, solid-filling medium 3 can include dry sand, so by dry sand, fluid pressure line 2 is covered, and do husky more open softness, this makes it possible to make fluid pressure line 2 effectively buffer, thus reach the effect of vibration damping.Simultaneously, it is to avoid fluid pressure line 2 covers 4 hard contact with base plate dam foundation base plate or second phase cast-in-place concrete, and if when there is multiple fluid pressure line 2, the most there is not hard contact between each fluid pressure line 2, be effectively prevented fluid pressure line 2 and deform.And after rejecting second phase cast-in-place concrete capping 4, dry sand is carried out cleaning and is easier, save the time, improve efficiency.
