Detailed description of the invention
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
As shown in Figure 7, a kind of rock-fill concrete construction method for wave wall basic platform, it comprises the following steps:
Step 1: as shown in Figure 1, lay grouting layer 2 at levee body 1 upper surface, grouting layer adopts the hardcore bed that ballast grain sizes is 10～100mm, rubble is transported on levee body 1 by the dull and stereotyped barge 3 that is provided with excavator 31, in the time of seawater ebb tide, lay, after having laid, roll compacting by excavator 21.
Step 2: as shown in Figure 2, in the each template 4 of building in the both sides of grouting layer 2; Template 4 adopts the wide piece stone for 50cm manually to grout and forms, and required mortar can be produced with mixer ship 5, delivers on dike with the high-front shovel 51 on mixer ship 5, and piece stone adopts and facilitates the hand that manpower is moved to remove piece.
Step 3: as shown in Figure 3 and Figure 4, bury gutter 6 underground and spread into enrockment 7 between two templates 4.For avoiding gutter 6 impaired, can first bury steel pipe 61 underground, the diameter of steel pipe 61 is greater than gutter 6, and steel pipe 61 is moved piece stone by workman 62 and is fixed; After enrockment is laid, gutter 6 is inserted to steel pipe 61, then steel pipe 61 is extracted.Like this, steel pipe can reuse, and can avoid gutter to spread in process and destroyed by crushing at enrockment simultaneously.Between two templates 4, form multiple enrockments storehouse, between two adjacent described enrockment storehouses, separate with asphalt plank.As shown in Figure 3 and Figure 4, the enrockment 7 used block of stone 82 that puts in storage is transported to scene by cargo ship 8, utilizes high-front shovel 81 to send Shi Shangdi, flattens by the excavator 71 on dike.Excavator 71 on dike can, along the construction that falls back of dike axis direction, to guarantee there are enough work planes in the situation that levee body 1 is narrower, avoid damaging the gutter of having buried underground.
Step 4: as shown in Figure 5, carry out wave wall reinforcing bar 9 pre-buried between two templates 4.By reinforcing bar cargo ship 10, the reinforcing bar processing is transported to job site, artificial colligation is pre-buried, and it is fixing that the steel mesh reinforcement forming after reinforcing bar binding utilizes enrockment space to bury underground.
Step 5: as shown in Figure 6, self-compacting concrete 11 is built and filled enrockment 7, form rock-fill concrete.Self-compacting concrete 11 is produced on-site on mixer ship 12, material ship 122 by transporting material to mixer ship 12, by the pumping system 121 on mixer ship 12, use and with the delivery pump pipeline of hinged suspension bridge, concrete conveyance is built and is filled in enrockment 7 gaps, can regulate pipeline location according to tidal fluctuations, avoid, because tidal fluctuations elongates pipeline or shortens, improving and building efficiency.Before self-compacting concrete pumping, self-compacting concrete is detected, check raw material and the mix-design of described self-compacting concrete, to meet national standard.Also can produce after self-compacting concrete, utilize high-front shovel to build rock-fill concrete, to reach the effect of economic environmental protection.
Construction method of the present invention, the position influence that makes moist is little, and do mechanization operation degree is high, and efficiency of construction is improved; Construction technology is simple, and human intervention is little, and quality easily ensures; Due to the skeleton function of rockfill, volume stability is good simultaneously, and quality aspect more easily ensures; Therefore, construction method of the present invention can be applicable to sea and be positioned at the construction of the wave wall basic platform in Lang Jian district and fluctuation of water table district well.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that this only illustrates, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these embodiments, but these changes and amendment all fall into protection scope of the present invention.
