Abstract
The present invention relates to the construction method of a kind of Tu Yan in conjunction with guard relay pile under geological conditions, comprise 1, survey report rock stratum height line chart according to Tu Yan in conjunction with the ground of geology and determine first campshed length and arrangement of reinforcement; 2, the position of absolute altitude distance 1m at the bottom of excavation of foundation pit to stake, the partial section for rock stratum not yet exposure is investigated; 3, after investigation, for the position needing construction relay stake, vacate first campshed 500mm clear distance and set up row's castinplace pile; 4, relay pile head arranges a corral purlin, encloses purlin near first campshed, fills in space with pea gravel concreten; 5, one support is added at collar tie beam position, for relay stake before and after consolidation.Present invention decreases design and construction difficulty, be specially adapted to coastal area Tu Yan in conjunction with geological conditions; It is long that relay stake effectively reduces stake, reduces verticality problem rambunctious under such geological conditions; Being excavated to after at the bottom of first campshed, can dig on a wide area be proceeded, only in local location slot milling construction relay stake, the duration need have been saved.
Description
Technical field
The present invention relates to a kind of for coastal area Tu Yan in conjunction with the fender post construction method under geological conditions.
Background technology
In coastal area, under sea terrestrial facies replace geological conditions, bedrock surface rises and falls very large, adopt conventional single bored pile as going along with sb. to guard him form, the determination of static parameter of holing has difficulties, the discrete type of geological prospecting is also difficult to that the stake of each pile is long to be determined to provide conclusive foundation, and this also can affect Force Calculation and the Reinforcement Design of fender post greatly.The requirement of longer stake long very difficult guarantee verticality, is also unfavorable for the whole cycle of constructing.
For this situation, carry out special design in conjunction with this type of situation run in three nuclear power station project construction processes, proposed the method for designing of guard relay pile.Three nuclear power first stage of the project are that China introduces third generation compressed water reactor nuclear power technology autonomy-oriented Project Cooperation, and construction project to be built geological conditions is multiple, and upper strata is backfill ragstone layer, and lower floor is tuff and sandstone, and whole rock stratum rises and falls very large, and the most shallow crop out, can reach 20m the most deeply.Especially in 1# siphonic water-collecting well region, violent rock stratum rises and falls and all brings very large difficulty to absolute altitude and Reinforcement Design at the bottom of the stake of bored pile.Therefore by the design of guard relay pile, solve this difficulty, save the duration.
Summary of the invention
The present invention will provide a kind of Tu Yan in conjunction with the construction method of guard relay pile under geological conditions, rising and falling large, going along with sb. to guard him the technical problem of constructional difficulties for solving Tu Yan in conjunction with regional rock stratum.
For achieving the above object, technical scheme of the present invention is: a kind of Tu Yan is in conjunction with the construction method of guard relay pile under geological conditions, and concrete steps are as follows:
1) survey report rock stratum height line chart according to Tu Yan in conjunction with the ground of geology and determine first campshed length and arrangement of reinforcement;
2) position of absolute altitude distance 1m at the bottom of excavation of foundation pit to stake, the partial section for rock stratum not yet exposure is investigated;
3), after investigation, for the position needing construction relay stake, vacate first campshed 500mm clear distance and set up row's castinplace pile;
4) relay pile head arranges a corral purlin, encloses purlin near first campshed, fills in space with pea gravel concreten;
5) one support is added at collar tie beam position, for relay stake before and after consolidation.
The invention has the beneficial effects as follows:
1, when considering average buried depth of bedrock, position large for bedrock relief being separated, reducing design and construction difficulty, being specially adapted to coastal area Tu Yan in conjunction with geological conditions;
2, effectively to reduce stake long in relay stake, reduces verticality problem rambunctious under such geological conditions;
3, being excavated to after at the bottom of first campshed, can dig on a wide area be proceeded, only in local location slot milling construction relay stake, the duration need have been saved;
4, between relay stake by enclose purlin, support system formed pin joint, ensure that the safety of front and back campshed.
Accompanying drawing explanation
Fig. 1 is working drawing of the present invention;
Fig. 2 is the sectional view along A-A in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As Fig. 1, shown in 2, Tu Yan of the present invention is in conjunction with the construction method of guard relay pile under geological conditions, and concrete steps are as follows:
1) survey report rock stratum height line chart according to Tu Yan in conjunction with the ground of geology and determine first campshed 1 length and arrangement of reinforcement;
2) position of absolute altitude distance 1m at the bottom of excavation of foundation pit to stake, the partial section for rock stratum not yet exposure is investigated;
3), after investigation, for the position needing construction relay stake 2, vacate first campshed 1,500mm clear distance and set up row's castinplace pile;
4) relay stake 2 pile crown arranges a corral purlin, encloses purlin near first campshed 1, fills in space with pea gravel concreten;
5) one support 3(anchor pole is added at collar tie beam position) for relay stake 2 before and after consolidation, make its stress performance reasonable.
