Embodiment 1

[0034] Embodiment 1 (as figure 1 ):

[0035] The utility model relates to an enclosure of a geocell, the main body of which is a multi-layer geogrid, and the cells of the geogrid are filled with sand, gravel or soil to form an enclosure. Set up inland side tie bars on the inner side slope of the enclosure.

[0036] The construction method is:

[0037] 1. On the completed foundation (according to the actual situation, adopt corresponding foundation treatment measures), lay the geocell filling layer upward in sequence;

[0038] 2. Each layer of geocell retracts inward for a certain distance to form a certain slope;

[0039] 3. When the filling layer of the geocell is laid to a certain height, the filling starts. It is necessary to choose whether to set the inland side tie bar at the same time of filling;

[0040] 4. Alternately carry out the laying and filling of geocell fill layers until the top of the enclosure;

[0041] 5. Each geocell is connected with the upper and low...

Embodiment 2

[0043] Embodiment 2 (as figure 2 ):

[0044] The utility model relates to an enclosure of a geocell, the main body of which is a multi-layer geogrid, and the cells of the geogrid are filled with sand, gravel or soil to form an enclosure. Set up inland side tie bars on the inner side slope of the enclosure. Set up the protective surface on the side facing the sea.

[0045] The construction method is:

[0046] 1. On the completed foundation (according to the actual situation, adopt corresponding foundation treatment measures), lay the geocell filling layer upward in sequence;

[0047] 2. Each layer of geocell retracts inward for a certain distance to form a certain slope;

[0048] 3. When the filling layer of the geocell is laid to a certain height, the filling starts. It is necessary to choose whether to set the inland side tie bar at the same time of filling;

[0049] 4. Alternately carry out the laying and filling of geocell fill layers until the top of the enclosure; ...

Embodiment 3

[0053] Embodiment 3 (as image 3 ):

[0054] The utility model relates to a geocell enclosure, in which side slopes on both sides are formed by multi-layer geogrids, and embankment core soil is filled between the side slopes. In the core soil of the embankment, an inner tie bar is set to connect the geogrid slopes on both sides. Set the inland side tie bars on the inner side slope.

[0055] The construction method is:

[0056]1. On the completed foundation (according to the actual situation, adopt corresponding foundation treatment measures), lay the geocell filling layer upward in sequence;

[0057] 2. Each layer of geocell retracts back a certain distance to form a certain slope;

[0058] 3. Fill the embankment core soil between the two side slopes formed by the geocell until the top of the enclosure;

[0059] 4. Set the internal tension belt at the appropriate position in the filling layer;

[0060] 5. According to the needs, choose whether to set the inland side tie ...

Abstract

The invention provides a geocell cofferdam, wherein a main body of the earthwork standard room cofferdam is formed by multiply layers of geogrids, and geocells of the geogrids are filled with sand ordetritus or clay to form the cofferdam. The invention further provides another geocell cofferdam, wherein two side slopes are formed by erecting multiple layers of geogrids, and breakwater core soil is filled between two side slopes. According to the invention, the cofferdam slopes have good integrity and sedimentation adaptability, have powerful lateral limitation and high rigidity and can fulfill the aims of enlarging a slope ratio of the slopes, reducing a cofferdam section, reducing material outward transport cost and saving engineering cost.

Description

technical field [0001] The invention belongs to the field of port engineering and relates to enclosure technology, in particular to an enclosure of geocells and a construction method thereof. Background technique [0002] At present, the enclosure is mainly used to enclose the construction area of ​​dredger fill, which is the main structural part of the dredger fill project and one of the main engineering measures for coastal protection. It is a barrier to protect coastal areas from wind waves and storm surges, and it is also a guarantee for flood control in estuary areas. [0003] The selection of the structure form of the enclosure is mainly based on the natural conditions of the project location, source of materials, use requirements and construction conditions, etc., and also comprehensively consider technical, economic and other factors. Due to the lack of technology and construction equipment capacity, the early dikes at home and abroad basically adopted the structure...
