  拉森钢板桩工程施工的时分,拉森钢板桩假设入土不可深的话,拉森钢板桩的支撑强度就不可,就会致使地下水或者是地下水带土流入沟槽。恶性循环就会致使拉森钢板桩背面的土体变形过大,直接致使拉森钢板桩失稳,地上就会遭到以下影响:
  During the construction of Larsen steel sheet pile project, if the Larsen steel sheet pile is not deep enough, the supporting strength of Larsen steel sheet pile will not be able, which will cause groundwater or groundwater with soil into the trench. The vicious circle will cause the soil deformation on the back of Larsen steel sheet pile to be too large, which will directly cause the instability of Larsen steel sheet pile, and the ground will be affected as follows:
  1、小变形地上沉降值≤50mm,就会影响到规划为1-1.5倍沟槽深度;
  1. When the ground settlement value of small deformation is less than 50 mm, it will affect the planned groove depth of 1-1.5 times.
  2、中等变形地上沉降值50-100mm,就会影响到规划大于1.5倍基坑开挖深度;
  2. The settlement value of medium deformation ground is 50-100 mm, which will affect the excavation depth of foundation pit which is more than 1.5 times as planned.
  3、大变形地上沉降值≥100mm,就会影响到规划大于2.5倍基坑开挖深度。
  3. The settlement value of large deformation ground (> 100mm) will affect the excavation depth of foundation pit which is more than 2.5 times as planned.
  因此在打拉森钢板桩入土要注意不能让泥土也进入了桩锁扣的本地,通常为了便当使用,通常都在锁扣处涂上油脂,以便当施工操作。在打钢板桩的过程中,一定要坚持拉森钢 板桩笔直,通常都是用经纬仪来检测的,打钢板桩时,一定要坚持前面的两个拉森钢板桩的方向要一起,才华便当后来的拉森钢板桩沿着前面的打桩。
  Therefore, when driving Larsen steel sheet pile into the soil, we should pay attention not to let the soil into the local lock of the pile. Usually, for convenience, grease is applied to the lock, so as to facilitate construction operation. In the process of driving steel sheet piles, we must adhere to the straight Larsen steel sheet piles, which are usually detected by theodolite. When driving steel sheet piles, we must adhere to the direction of the two Larsen steel sheet piles in front of each other. Only then can the later Larsen steel sheet piles be driven along the front.
  假设拉森钢板桩入土不可深,支撑强度不可,则要思考拉森钢板桩内支撑进行加固,对于钢板桩的加固,是要在确保安全的前提下,拉森钢板桩内支撑的施工与基坑内水位或泥面/土面的下降按“先支撑后降水或吸泥,分层支撑分层降水或吸泥”的准则进行。可以这么说拉森钢板桩的加固是盘绕拉森钢板桩围檩的支撑进行的,从加固的支撑次第就可以看出来。

  Assuming that the Larsen steel sheet pile is not deep enough to support, it is necessary to consider the reinforcement of the internal support of the Larsen steel sheet pile. For the reinforcement of the steel sheet pile, the construction of the internal support of the Larsen steel sheet pile and the decline of the water level or the mud/soil surface in the foundation pit should be carried out according to the criterion of "supporting first, dewatering or sucking mud, layered support, dewatering or sucking mud". It can be said that the reinforcement of Larsen steel sheet pile is carried out around the purlin of Larsen steel sheet pile, which can be seen from the support order of reinforcement.
  拉森钢板桩内支撑加固的次第:
  Larsen steel sheet pile internal support reinforcement in the second place:
  1、抽水/取土至层支撑处;
  1. Pumping/extracting soil to the first support;
  2、加层围檩及内撑;
  2. Add the first purlin and brace;
  3、吸泥/取土至第二层支撑处;
  3. Soil suction/extraction to the second support;
  4、加第二层围檩及内撑;
  4. Adding the second purlin and brace;
  5、吸泥/取土至基坑底。
  5. Soil suction/extraction to the bottom of the foundation pit.
  拉森钢板桩围檩的支撑包括围檩及内撑,选用两层安顿,两层标高分别为0.0m、-4.8m。
  The support of purlin of Larsen steel sheet pile includes purlin and inner support. Two layers of purlin are selected to settle down. The elevations of the two layers are 0.0m and - 4.8m, respectively.
  拉森钢板桩的用处十分广泛,可以用在永久性构造修建上,也可以用在临时性构筑物上。例如修建地铁站、地道、建桥围堰、驳岸、市政工程、土建工程的深基坑、沟槽、管道、地下室等挡土、挡水的开挖围护等等,在这些工程建造上体现重要作用。因此我们在进行拉森钢板桩施工的时分一定要注意细节疑问。
  Larsen steel sheet piles are widely used in permanent structures and temporary structures. For example, the construction of subway stations, tunnels, bridges, cofferdams, revetments, municipal works, deep foundation pits of civil engineering, trenches, pipelines, basements and other retaining soil, water retaining excavation and enclosure, etc., play an important role in the construction of these projects. Therefore, we must pay attention to the details of the construction of Larsen steel sheet pile.
